Public Speaking: Developing a Thesis Statement In a Speech

Understanding the purpose of a thesis statement in a speech

Diving headfirst into the world of public speaking, it’s essential to grasp the role of a thesis statement in your speech. Think of it as encapsulating the soul of your speech within one or two sentences.

It’s the declarative sentence that broadcasts your intent and main idea to captivate audiences from start to finish. More than just a preview, an effective thesis statement acts as a roadmap guiding listeners through your thought process.

Giving them that quick glimpse into what they can anticipate helps keep their attention locked in.

As you craft this central hub of information, understand that its purpose is not limited to informing alone—it could be meant also to persuade or entertain based on what you aim for with your general purpose statement.

This clear focus is pivotal—it shapes each aspect of your talk, easing understanding for the audience while setting basic goals for yourself throughout the speech-making journey. So whether you are rallying rapturous applause or instigating intellectual insight, remember—your thesis statement holds power like none other! Its clarity and strength can transition between being valuable sidekicks in introductions towards becoming triumphant heroes by concluding lines.

Identifying the main idea to develop a thesis statement

In crafting a compelling speech, identifying the main idea to develop a thesis statement acts as your compass. This process is a crucial step in speech preparation that steers you towards specific purpose.

Think of your central idea as the seed from which all other elements in your speech will grow.

To pinpoint it, start by brainstorming broad topics that interest or inspire you. From this list, choose one concept that stands out and begin to narrow it down into more specific points. It’s these refined ideas that form the heart of your thesis statement — essentially acting as signposts leading the audience through your narrative journey.

Crafting an effective thesis statement requires clarity and precision. This means keeping it concise without sacrificing substance—a tricky balancing act even for public speaking veterans! The payoff though? A well-developed thesis statement provides structure to amplifying your central idea and guiding listeners smoothly from point A to B.

It’s worth noting here: just like every speaker has their own unique style, there are multiple ways of structuring a thesis statement too. But no matter how you shape yours, ensuring it resonates with both your overarching message and audience tastes will help cement its effectiveness within your broader presentation context.

Analyzing the audience to tailor the thesis statement

Audience analysis is a crucial first step for every public speaker. This process involves adapting the message to meet the audience’s needs, a thoughtful approach that considers cultural diversity and ensures clear communication.

Adapting your speech to resonate with your target audience’s interests, level of understanding, attitudes and beliefs can significantly affect its impact.

Crafting an appealing thesis statement hinges on this initial stage of audience analysis. As you analyze your crowd, focus on shaping a specific purpose statement that reflects their preferences yet stays true to the objective of your speech—capturing your main idea in one or two impactful sentences.

This balancing act demands strategy; however, it isn’t impossible. Taking into account varying aspects such as culture and perceptions can help you tailor a well-received thesis statement. A strong handle on these elements allows you to select language and tones best suited for them while also reflecting the subject at hand.

Ultimately, putting yourself in their shoes helps increase message clarity which crucially leads to acceptance of both you as the speaker and your key points – all embodied within the concise presentation of your tailor-made thesis statement.

Brainstorming techniques to generate thesis statement ideas

Leveraging brainstorming techniques to generate robust thesis statement ideas is a power move in public speaking. This process taps into the GAP model, focusing on your speech’s Goals, Audience, and Parameters for seamless target alignment.

Dive into fertile fields of thought and let your creativity flow unhindered like expert David Zarefsky proposes.

Start by zeroing in on potential speech topics then nurture them with details till they blossom into fully-fledged arguments. It’s akin to turning stones into gems for the eye of your specific purpose statement.

Don’t shy away from pushing the envelope – sometimes out-of-the-box suggestions give birth to riveting speeches! Broaden your options if parameters are flexible but remember focus is key when aiming at narrow targets.

The beauty lies not just within topic generation but also formulation of captivating informative or persuasive speech thesis statements; both fruits harvested from a successful brainstorming session.

So flex those idea muscles, encourage intellectual growth and watch as vibrant themes spring forth; you’re one step closer to commanding attention!

Remember: Your thesis statement is the heartbeat of your speech – make it strong using brainstorming techniques and fuel its pulse with evidence-backed substance throughout your presentation.

Narrowing down the thesis statement to a specific topic

Crafting a compelling thesis statement for your speech requires narrowing down a broad topic to a specific focus that can be effectively covered within the given time frame. This step is crucial as it helps you maintain clarity and coherence throughout your presentation.

Start by brainstorming various ideas related to your speech topic and then analyze them critically to identify the most relevant and interesting points to discuss. Consider the specific purpose of your speech and ask yourself what key message you want to convey to your audience.

By narrowing down your thesis statement, you can ensure that you address the most important aspects of your chosen topic, while keeping it manageable and engaging for both you as the speaker and your audience.

Choosing the appropriate language and tone for the thesis statement

Crafting the appropriate language and tone for your thesis statement is a crucial step in developing a compelling speech. Your choice of language and tone can greatly impact how your audience perceives your message and whether they are engaged or not.

When choosing the language for your thesis statement, it’s important to consider the level of formality required for your speech. Are you speaking in a professional setting or a casual gathering? Adjusting your language accordingly will help you connect with your audience on their level and make them feel comfortable.

Additionally, selecting the right tone is essential to convey the purpose of your speech effectively. Are you aiming to inform, persuade, or entertain? Each objective requires a different tone: informative speeches may call for an objective and neutral tone, persuasive speeches might benefit from more assertive language, while entertaining speeches can be lighthearted and humorous.

Remember that clarity is key when crafting your thesis statement’s language. Using concise and straightforward wording will ensure that your main idea is easily understood by everyone in the audience.

By taking these factors into account – considering formality, adapting to objectives, maintaining clarity – you can create a compelling thesis statement that grabs attention from the start and sets the stage for an impactful speech.

Incorporating evidence to support the thesis statement

Incorporating evidence to support the thesis statement is a critical aspect of delivering an effective speech. As public speakers, we understand the importance of backing up our claims with relevant and credible information.

When it comes to incorporating evidence, it’s essential to select facts, examples, and opinions that directly support your thesis statement.

To ensure your evidence is relevant and reliable, consider conducting thorough research on the topic at hand. Look for trustworthy sources such as academic journals, respected publications, or experts in the field.

By choosing solid evidence that aligns with your message, you can enhance your credibility as a speaker.

When presenting your evidence in the speech itself, be sure to keep it concise and clear. Avoid overwhelming your audience with excessive details or data. Instead, focus on selecting key points that strengthen your argument while keeping their attention engaged.

Remember that different types of evidence can be utilized depending on the nature of your speech. You may include statistical data for a persuasive presentation or personal anecdotes for an informative talk.

The choice should reflect what will resonate best with your audience and effectively support your thesis statement.

By incorporating strong evidence into our speeches, we not only bolster our arguments but also build trust with our listeners who recognize us as reliable sources of information. So remember to choose wisely when including supporting material – credibility always matters when making an impact through public speaking.

Avoiding common mistakes when developing a thesis statement

Crafting an effective thesis statement is vital for public speakers to deliver a compelling and focused speech. To avoid common mistakes when developing a thesis statement , it is essential to be aware of some pitfalls that can hinder the impact of your message.

One mistake to steer clear of is having an incomplete thesis statement. Ensure that your thesis statement includes all the necessary information without leaving any key elements out. Additionally, avoid wording your thesis statement as a question as this can dilute its potency.

Another mistake to watch out for is making statements of fact without providing evidence or support. While it may seem easy to write about factual information, it’s important to remember that statements need to be proven and backed up with credible sources or examples.

To create a more persuasive argument, avoid using phrases like “I believe” or “I feel.” Instead, take a strong stance in your thesis statement that encourages support from the audience. This will enhance your credibility and make your message more impactful.

By avoiding these common mistakes when crafting your thesis statement, you can develop a clear, engaging, and purposeful one that captivates your audience’s attention and guides the direction of your speech effectively.

Revising the thesis statement to enhance clarity and coherence

Revising the thesis statement is a crucial step in developing a clear and coherent speech. The thesis statement serves as the main idea or argument that guides your entire speech, so it’s important to make sure it effectively communicates your message to the audience.

To enhance clarity and coherence in your thesis statement, start by refining and strengthening it through revision . Take into account any feedback you may have received from others or any new information you’ve gathered since initially developing the statement.

Consider if there are any additional points or evidence that could further support your main idea.

As you revise, focus on clarifying the language and tone of your thesis statement. Choose words that resonate with your audience and clearly convey your point of view. Avoid using technical jargon or overly complicated language that might confuse or alienate listeners.

Another important aspect of revising is ensuring that your thesis statement remains focused on a specific topic. Narrow down broad ideas into more manageable topics that can be explored thoroughly within the scope of your speech.

Lastly, consider incorporating evidence to support your thesis statement. This could include statistics, examples, expert opinions, or personal anecdotes – whatever helps strengthen and validate your main argument.

By carefully revising your thesis statement for clarity and coherence, you’ll ensure that it effectively conveys your message while capturing the attention and understanding of your audience at large.

Testing the thesis statement to ensure it meets the speech’s objectives.

Testing the thesis statement is a crucial step to ensure that it effectively meets the objectives of your speech. By testing the thesis statement , you can assess its clarity, relevance, and impact on your audience.

One way to test your thesis statement is to consider its purpose and intent. Does it clearly communicate what you want to achieve with your speech? Is it concise and specific enough to guide your content?.

Another important aspect of testing the thesis statement is analyzing whether it aligns with the needs and interests of your audience. Consider their background knowledge, values, and expectations.

Will they find the topic engaging? Does the thesis statement address their concerns or provide valuable insights?.

In addition to considering purpose and audience fit, incorporating supporting evidence into your speech is vital for testing the effectiveness of your thesis statement. Ensure that there is relevant material available that supports your claim.

To further enhance clarity and coherence in a tested thesis statement, revise it if necessary based on feedback from others or through self-reflection. This will help refine both language choices and overall effectiveness.

By thoroughly testing your thesis statement throughout these steps, you can confidently develop a clear message for an impactful speech that resonates with your audience’s needs while meeting all stated objectives.

Once you have captured your audience’s attention, it’s important to make the rest of your introduction interesting, and use it to lay out the rest of the speech. In this section, we are going to explore the five remaining parts of an effective introduction: linking to your topic, reasons to listen, stating credibility, thesis statement, and preview.

Link to Topic

After the attention-getter, the second major part of an introduction is called the link to topic. The link to topic is the shortest part of an introduction and occurs when a speaker demonstrates how an attention-getting device relates to the topic of a speech. Often the attention-getter and the link to topic are very clear. For example, if you look at the attention-getting device example under historical reference above, you’ll see that the first sentence brings up the history of the Vietnam War and then shows us how that war can help us understand the Iraq War. In this case, the attention-getter clearly flows directly to the topic. However, some attention-getters need further explanation to get to the topic of the speech. For example, both of the anecdote examples (the girl falling into the manhole while texting and the boy and the filberts) need further explanation to connect clearly to the speech topic (i.e., problems of multitasking in today’s society).

Let’s look at the first anecdote example to demonstrate how we could go from the attention-getter to the topic.

In July 2009, a high school girl named Alexa Longueira was walking along a main boulevard near her home on Staten Island, New York, typing in a message on her cell phone. Not paying attention to the world around her, she took a step and fell right into an open manhole. This anecdote illustrates the problem that many people are facing in today’s world. We are so wired into our technology that we forget to see what’s going on around us—like a big hole in front of us.

In this example, the third sentence here explains that the attention-getter was an anecdote that illustrates a real issue. The fourth sentence then introduces the actual topic of the speech.

Let’s now examine how we can make the transition from the parable or fable attention-getter to the topic:

The ancient Greek writer Aesop told a fable about a boy who put his hand into a pitcher of filberts. The boy grabbed as many of the delicious nuts as he possibly could. But when he tried to pull them out, his hand wouldn’t fit through the neck of the pitcher because he was grasping so many filberts. Instead of dropping some of them so that his hand would fit, he burst into tears and cried about his predicament. The moral of the story? “Don’t try to do too much at once.” In today’s world, many of us are us are just like the boy putting his hand into the pitcher. We are constantly trying to grab so much or do so much that it prevents us from accomplishing our goals. I would like to show you three simple techniques to manage your time so that you don’t try to pull too many filberts from your pitcher.

In this example, we added three new sentences to the attention-getter to connect it to the speech topic.

Reasons to Listen

Once you have linked an attention-getter to the topic of your speech, you need to explain to your audience why your topic is important. We call this the “why should I care?” part of your speech because it tells your audience why the topic is directly important to them. Sometimes you can include the significance of your topic in the same sentence as your link to the topic, but other times you may need to spell out in one or two sentences why your specific topic is important.

People in today’s world are very busy, and they do not like their time wasted. Nothing is worse than having to sit through a speech that has nothing to do with you. Imagine sitting through a speech about a new software package you don’t own and you will never hear of again. How would you react to the speaker? Most of us would be pretty annoyed at having had our time wasted in this way. Obviously, this particular speaker didn’t do a great job of analyzing her or his audience if the audience isn’t going to use the software package—but even when speaking on a topic that is highly relevant to the audience, speakers often totally forget to explain how and why it is important.

Appearing Credible

The next part of a speech is not so much a specific “part” as an important characteristic that needs to be pervasive throughout your introduction and your entire speech. As a speaker, you want to be seen as credible (competent, trustworthy, and caring/having goodwill). As mentioned earlier in this chapter, credibility is ultimately a perception that is made by your audience. While your audience determines whether they perceive you as competent, trustworthy, and caring/having goodwill, there are some strategies you can employ to make yourself appear more credible.

First, to make yourself appear competent, you can either clearly explain to your audience why you are competent about a given subject or demonstrate your competence by showing that you have thoroughly researched a topic by including relevant references within your introduction. The first method of demonstrating competence—saying it directly—is only effective if you are actually a competent person on a given subject. If you are an undergraduate student and you are delivering a speech about the importance of string theory in physics, unless you are a prodigy of some kind, you are probably not a recognized expert on the subject. Conversely, if your number one hobby in life is collecting memorabilia about the Three Stooges, then you may be an expert about the Three Stooges. However, you would need to explain to your audience your passion for collecting Three Stooges memorabilia and how this has made you an expert on the topic.

If, on the other hand, you are not actually a recognized expert on a topic, you need to demonstrate that you have done your homework to become more knowledgeable than your audience about your topic. The easiest way to demonstrate your competence is through the use of appropriate references from leading thinkers and researchers on your topic. When you demonstrate to your audience that you have done your homework, they are more likely to view you as competent.

The second characteristic of credibility, trustworthiness, is a little more complicated than competence, for it ultimately relies on audience perceptions. One way to increase the likelihood that a speaker will be perceived as trustworthy is to use reputable sources. If you’re quoting Dr. John Smith, you need to explain who Dr. John Smith is so your audience will see the quotation as being more trustworthy. As speakers we can easily manipulate our sources into appearing more credible than they actually are, which would be unethical. When you are honest about your sources with your audience, they will trust you and your information more so than when you are ambiguous. The worst thing you can do is to out-and-out lie about information during your speech. Not only is lying highly unethical, but if you are caught lying, your audience will deem you untrustworthy and perceive everything you are saying as untrustworthy. Many speakers have attempted to lie to an audience because it will serve their own purposes or even because they believe their message is in their audience’s best interest, but lying is one of the fastest ways to turn off an audience and get them to distrust both the speaker and the message.

The third characteristic of credibility to establish during the introduction is the sense of caring/goodwill. While some unethical speakers can attempt to manipulate an audience’s perception that the speaker cares, ethical speakers truly do care about their audiences and have their audience’s best interests in mind while speaking. Often speakers must speak in front of audiences that may be hostile toward the speaker’s message. In these cases, it is very important for the speaker to explain that he or she really does believe her or his message is in the audience’s best interest. One way to show that you have your audience’s best interests in mind is to acknowledge disagreement from the start:

Today I’m going to talk about why I believe we should enforce stricter immigration laws in the United States. I realize that many of you will disagree with me on this topic. I used to believe that open immigration was a necessity for the United States to survive and thrive, but after researching this topic, I’ve changed my mind. While I may not change all of your minds today, I do ask that you listen with an open mind, set your personal feelings on this topic aside, and judge my arguments on their merits.

While clearly not all audience members will be open or receptive to opening their minds and listening to your arguments, by establishing that there is known disagreement, you are telling the audience that you understand their possible views and are not trying to attack their intellect or their opinions.

Thesis Statement

A thesis statement is a short, declarative sentence that states the purpose, intent, or main idea of a speech. A strong, clear thesis statement is very valuable within an introduction because it lays out the basic goal of the entire speech. We strongly believe that it is worthwhile to invest some time in framing and writing a good thesis statement. You may even want to write your thesis statement before you even begin conducting research for your speech. While you may end up rewriting your thesis statement later, having a clear idea of your purpose, intent, or main idea before you start searching for research will help you focus on the most appropriate material. To help us understand thesis statements, we will first explore their basic functions and then discuss how to write a thesis statement.

Basic Functions of a Thesis Statement

A thesis statement helps your audience by letting them know “in a nutshell” what you are going to talk about. With a good thesis statement you will fulfill four basic functions: you express your specific purpose, provide a way to organize your main points, make your research more effective, and enhance your delivery.

Express Your Specific Purpose

To orient your audience, you need to be as clear as possible about your meaning. A strong thesis will prepare your audience effectively for the points that will follow. Here are two examples:

“Today, I want to discuss academic cheating.” (weak example)
“Today, I will clarify exactly what plagiarism is and give examples of its different types so that you can see how it leads to a loss of creative learning interaction.” (strong example)

The weak statement will probably give the impression that you have no clear position about your topic because you haven’t said what that position is. Additionally, the term “academic cheating” can refer to many behaviors—acquiring test questions ahead of time, copying answers, changing grades, or allowing others to do your coursework—so the specific topic of the speech is still not clear to the audience.

The strong statement not only specifies plagiarism but also states your specific concern (loss of creative learning interaction).

Provide a Way to Organize Your Main Points

When your thesis statement is sufficiently clear and decisive, you will know where you stand about your topic and where you intend to go with your speech. Having a clear thesis statement is especially important if you know a great deal about your topic or you have strong feelings about it. If this is the case for you, you need to know exactly what you are planning on talking about in order to fit within specified time limitations. Knowing where you are and where you are going is the entire point in establishing a thesis statement; it makes your speech much easier to prepare and to present.

Let’s say you have a fairly strong thesis statement, and that you’ve already brainstormed a list of information that you know about the topic. Chances are your list is too long and has no focus. Using your thesis statement, you can select only the information that (1) is directly related to the thesis and (2) can be arranged in a sequence that will make sense to the audience and will support the thesis. In essence, a strong thesis statement helps you keep useful information and weed out less useful information.

Make Your Research More Effective

If you begin your research with only a general topic in mind, you run the risk of spending hours reading mountains of excellent literature about your topic. However, mountains of literature do not always make coherent speeches. You may have little or no idea of how to tie your research all together, or even whether you should tie it together. If, on the other hand, you conduct your research with a clear thesis statement in mind, you will be better able to zero in only on material that directly relates to your chosen thesis statement. Let’s look at an example that illustrates this point:

Many traffic accidents involve drivers older than fifty-five.

While this statement may be true, you could find industrial, medical, insurance literature that can drone on ad infinitum about the details of all such accidents in just one year. Instead, focusing your thesis statement will help you narrow the scope of information you will be searching for while gathering information. Here’s an example of a more focused thesis statement:

Three factors contribute to most accidents involving drivers over fifty-five years of age: failing eyesight, slower reflexes, and rapidly changing traffic conditions.

This framing is somewhat better. This thesis statement at least provides three possible main points and some keywords for your electronic catalog search. However, if you want your audience to understand the context of older people at the wheel, consider something like:

Mature drivers over fifty-five years of age must cope with more challenging driving conditions than existed only one generation ago: more traffic moving at higher speeds, the increased imperative for quick driving decisions, and rapidly changing ramp and cloverleaf systems. Because of these challenges, I want my audience to believe that drivers over the age of sixty-five should be required to pass a driving test every five years.

This framing of the thesis provides some interesting choices. First, several terms need to be defined, and these definitions might function surprisingly well in setting the tone of the speech. Your definitions of words like “generation,” “quick driving decisions,” and “cloverleaf systems” could jolt your audience out of assumptions they have taken for granted as truth.

Second, the framing of the thesis provides you with a way to describe the specific changes as they have occurred between, say, 1970 and 2010. How much, and in what ways, have the volume and speed of traffic changed? Why are quick decisions more critical now? What is a “cloverleaf,” and how does any driver deal cognitively with exiting in the direction seemingly opposite to the desired one? Questions like this, suggested by your own thesis statement, can lead to a strong, memorable speech.

Enhance Your Delivery

When your thesis is not clear to you, your listeners will be even more clueless than you are—but if you have a good clear thesis statement, your speech becomes clear to your listeners. When you stand in front of your audience presenting your introduction, you can vocally emphasize the essence of your speech, expressed as your thesis statement. Many speakers pause for a half second, lower their vocal pitch slightly, slow down a little, and deliberately present the thesis statement, the one sentence that encapsulates its purpose. When this is done effectively, the purpose, intent, or main idea of a speech is driven home for an audience.

How to Write a Thesis Statement

Now that we’ve looked at why a thesis statement is crucial in a speech, let’s switch gears and talk about how we go about writing a solid thesis statement. A thesis statement is related to the general and specific purposes of a speech as we discussed them in Chapter 6 “Finding a Purpose and Selecting a Topic” .

Choose Your Topic

The first step in writing a good thesis statement was originally discussed in Chapter 6 “Finding a Purpose and Selecting a Topic” when we discussed how to find topics. Once you have a general topic, you are ready to go to the second step of creating a thesis statement.

Narrow Your Topic

One of the hardest parts of writing a thesis statement is narrowing a speech from a broad topic to one that can be easily covered during a five- to ten-minute speech. While five to ten minutes may sound like a long time to new public speakers, the time flies by very quickly when you are speaking. You can easily run out of time if your topic is too broad. To ascertain if your topic is narrow enough for a specific time frame, ask yourself three questions.

First, is your thesis statement narrow or is it a broad overgeneralization of a topic? An overgeneralization occurs when we classify everyone in a specific group as having a specific characteristic. For example, a speaker’s thesis statement that “all members of the National Council of La Raza are militant” is an overgeneralization of all members of the organization. Furthermore, a speaker would have to correctly demonstrate that all members of the organization are militant for the thesis statement to be proven, which is a very difficult task since the National Council of La Raza consists of millions of Hispanic Americans. A more appropriate thesis related to this topic could be, “Since the creation of the National Council of La Raza [NCLR] in 1968, the NCLR has become increasingly militant in addressing the causes of Hispanics in the United States.”

The second question to ask yourself when narrowing a topic is whether your speech’s topic is one clear topic or multiple topics. A strong thesis statement consists of only a single topic. The following is an example of a thesis statement that contains too many topics: “Medical marijuana, prostitution, and gay marriage should all be legalized in the United States.” Not only are all three fairly broad, but you also have three completely unrelated topics thrown into a single thesis statement. Instead of a thesis statement that has multiple topics, limit yourself to only one topic. Here’s an example of a thesis statement examining only one topic: “Today we’re going to examine the legalization and regulation of the oldest profession in the state of Nevada.” In this case, we’re focusing our topic to how one state has handled the legalization and regulation of prostitution.

The last question a speaker should ask when making sure a topic is sufficiently narrow is whether the topic has direction. If your basic topic is too broad, you will never have a solid thesis statement or a coherent speech. For example, if you start off with the topic “Barack Obama is a role model for everyone,” what do you mean by this statement? Do you think President Obama is a role model because of his dedication to civic service? Do you think he’s a role model because he’s a good basketball player? Do you think he’s a good role model because he’s an excellent public speaker? When your topic is too broad, almost anything can become part of the topic. This ultimately leads to a lack of direction and coherence within the speech itself. To make a cleaner topic, a speaker needs to narrow her or his topic to one specific area. For example, you may want to examine why President Obama is a good speaker.

Put Your Topic into a Sentence

Once you’ve narrowed your topic to something that is reasonably manageable given the constraints placed on your speech, you can then formalize that topic as a complete sentence. For example, you could turn the topic of President Obama’s public speaking skills into the following sentence: “Because of his unique sense of lyricism and his well-developed presentational skills, President Barack Obama is a modern symbol of the power of public speaking.” Once you have a clear topic sentence, you can start tweaking the thesis statement to help set up the purpose of your speech.

Add Your Argument, Viewpoint, or Opinion

This function only applies if you are giving a speech to persuade. If your topic is informative, your job is to make sure that the thesis statement is nonargumentative and focuses on facts. For example, in the preceding thesis statement we have a couple of opinion-oriented terms that should be avoided for informative speeches: “unique sense,” “well-developed,” and “power.” All three of these terms are laced with an individual’s opinion, which is fine for a persuasive speech but not for an informative speech. For informative speeches, the goal of a thesis statement is to explain what the speech will be informing the audience about, not attempting to add the speaker’s opinion about the speech’s topic. For an informative speech, you could rewrite the thesis statement to read, “This speech is going to analyze Barack Obama’s use of lyricism in his speech, ‘A World That Stands as One,’ delivered July 2008 in Berlin.”

On the other hand, if your topic is persuasive, you want to make sure that your argument, viewpoint, or opinion is clearly indicated within the thesis statement. If you are going to argue that Barack Obama is a great speaker, then you should set up this argument within your thesis statement.

Use the Thesis Checklist

Once you have written a first draft of your thesis statement, you’re probably going to end up revising your thesis statement a number of times prior to delivering your actual speech. A thesis statement is something that is constantly tweaked until the speech is given. As your speech develops, often your thesis will need to be rewritten to whatever direction the speech itself has taken. We often start with a speech going in one direction, and find out through our research that we should have gone in a different direction. When you think you finally have a thesis statement that is good to go for your speech, take a second and make sure it adheres to the criteria shown in Table 9.1 “Thesis Checklist”

Table 9.1 Thesis Checklist

Preview of Speech

The final part of an introduction contains a preview of the major points to be covered within your speech. I’m sure we’ve all seen signs that have three cities listed on them with the mileage to reach each city. This mileage sign is an indication of what is to come. A preview works the same way. A preview foreshadows what the main body points will be in the speech. For example, to preview a speech on bullying in the workplace, one could say, “To understand the nature of bullying in the modern workplace, I will first define what workplace bullying is and the types of bullying, I will then discuss the common characteristics of both workplace bullies and their targets, and lastly, I will explore some possible solutions to workplace bullying.” In this case, each of the phrases mentioned in the preview would be a single distinct point made in the speech itself. In other words, the first major body point in this speech would examine what workplace bullying is and the types of bullying; the second major body point in this speech would discuss the common characteristics of both workplace bullies and their targets; and lastly, the third body point in this speech would explore some possible solutions to workplace bullying.

4 Topic, Purpose, and Thesis

Learning objectives.

Differentiate among the three types of general speech purposes.
Understand the four primary constraints of topic selection.
Demonstrate an understanding of how a topic is narrowed from a broad subject area to a manageable specific purpose.
Integrate the seven tips for creating specific purposes.
Understand how to develop a strong thesis and assess thesis statements.

In the 2004 Tony Award-winning musical Avenue Q , the lead character sings a song about finding his purpose in life: “I don’t know how I know, but I’m gonna find my purpose. I don’t know where I’m gonna look, but I’m gonna find my purpose.” Although the song is about life in general, the lyrics are also appropriate when thinking about the purpose of your speech. You may know that you have been assigned to deliver a speech, but finding a purpose and topic seems like a formidable task. You may be asking yourself questions like, “What if the topic I pick is too common?”; “What if no one is interested in my topic?”; “What if my topic is too huge to cover in a three- to five-minute speech?”; or many others.

Finding a speech’s purpose and topic isn’t as complex or difficult as you might believe. This may be hard to accept right now but trust us. After you read this chapter, you’ll understand how to go about finding interesting topics for a variety of different types of speeches. In this chapter, we are going to explain how to identify the general purpose of a speech. We will also discuss how to select a topic, what to do if you’re just drawing a blank, and four basic questions you should ask yourself about the speech topic you ultimately select. Finally, we will explain how to use your general purpose and your chosen topic to develop the specific purpose and thesis of your speech.

General Purpose

What do you think of when you hear the word “purpose”? Technically speaking, a purpose is why something exists, how we use an object, or why we make something. For the purposes of public speaking, all three can be applied. For example, when we talk about a speech’s purpose, we can question why a specific speech was given, how we are supposed to use the information within a speech, and why we are personally creating a speech. For this specific chapter, we are more interested in that last aspect of the definition of the word “purpose”: why we give speeches.

Ever since scholars started writing about public speaking as a distinct phenomenon, there have been a range of different systems created to classify the types of speeches people may give. Aristotle talked about three speech purposes: deliberative (political speech), forensic (courtroom speech), and epideictic (speech of praise or blame). Cicero also talked about three purposes: judicial (courtroom speech), deliberative (political speech), and demonstrative (ceremonial speech—similar to Aristotle’s epideictic). A little more recently, St. Augustine of Hippo also wrote about three specific speech purposes: to teach (provide people with information), to delight (entertain people or show people false ideas), and to sway (persuade people to a religious ideology). All these systems of identifying public speeches have been attempts at helping people determine the general purpose of their speech. A general purpose refers to the broad goal of creating and delivering a speech.

These typologies or classification systems of public speeches serve to demonstrate that general speech purposes have remained pretty consistent throughout the history of public speaking. Modern public speaking scholars typically use a classification system for three general purposes: to inform, to persuade, and to entertain.

A general purpose refers to the broad goal of creating and delivering a speech.

The first general purpose that some people have for giving speeches is to inform. Simply put, informative speaking is about helping audience members acquire information that they do not already possess. Audience members can then use this information to understand something (e.g. a speech on a new technology or a speech on an issue of community concern) or to perform a new task or improve their skills (e.g. a speech on how to swing a golf club or a speech on how to assemble a layer cake). The most important characteristic of informative topics is that the goal is to gain knowledge. Notice that the goal is not to encourage people to use that knowledge in any specific way. When a speaker starts encouraging people to use knowledge in a specific way, they are no longer informing but instead persuading.

Informative speaking is about helping audience members acquire information that they do not already possess.

Let’s look at a real example of how an individual can accidentally go from informing to persuading. Let’s say you are assigned to inform an audience about a new vaccination program. In an informative speech, the purpose of the speech is to explain to your audience what the program is and how it works. If, however, you start encouraging your audience to participate in the vaccination program, you are no longer informing them about the program but instead persuading them to become involved in the program. One of the most common mistakes new public speaking students make is to blur the line between informing and persuading.

Why We Share Knowledge

Knowledge sharing is the process of delivering information, skills, or expertise in some form to people who could benefit from it. Every year, millions of people attend some kind of knowledge sharing conference or convention in hopes of learning new information or skills that will help them in their personal or professional lives (Atwood, 2009).

People are motivated to share their knowledge with other people for a variety of reasons (Hendriks, 1999). For some, the personal sense of achievement or responsibility drives them to share their knowledge (internal motivational factors). Others are compelled to share knowledge because of the desire for recognition or the possibility of job enhancement (external motivational factors). Knowledge sharing is an integral part of every society, so learning how to deliver informative speeches is a valuable skill.

Knowledge sharing is the process of delivering information, skills, or expertise in some form to people who could benefit from it.

Common Types of Informative Topics

O’Hair, Stewart, and Rubenstein identified six general types of informative speech topics: objects, people, events, concepts, processes, and issues (O’Hair, et al., 2007). The first type of informative speech relates to objects, which can include how objects are designed, how they function, and what they mean. For example, a student of one of our coauthors gave a speech on the design of corsets, using a mannequin to demonstrate how corsets were placed on women and the amount of force necessary to lace one up.

The second type of informative speech focuses on people. People-based speeches tend to be biography-oriented. Such topics could include recounting an individual’s achievements and explaining why he or she is important in history. Some speakers, who are famous themselves, will focus on their own lives and how various events shaped who they ultimately became. Dottie Walters noted as being the first female in the United States to run an advertising agency. In addition to her work in advertising, Dottie also spent a great deal of time as a professional speaker. She often would tell the story about her early years in advertising when she would push around a stroller with her daughter inside as she went from business to business trying to generate interest in her copywriting abilities. You don’t have to be famous, however, to give a people-based speech. Instead, you could inform your audience about a historical or contemporary hero whose achievements are not widely known.

The third type of informative speech involves explaining the significance of specific events, either historical or contemporary. For example, you could deliver a speech on a particular battle of World War II or a specific presidential administration. If you’re a history buff, event-oriented speeches may be right up your alley. There are countless historical events that many people aren’t familiar with and would find interesting. You could also inform your audience about a more recent or contemporary event. Some examples include concerts, plays, and arts festivals; athletic competitions; and natural phenomena, such as storms, eclipses, and earthquakes. The point is to make sure that an informative speech is talking about the event (who, what, when, where, and why) and not attempting to persuade people to pass judgment upon the event or its effects.

The fourth type of informative speech involves concepts, or “abstract and difficult ideas or theories” (O’Hair, et al., 2007). For example, if you want to explain a specific communication theory, E. M. Griffin provides an excellent list of communication theories on his website , http://www.afirstlook.com/main.cfm/theory_list . Whether you want to discuss theories related to business, sociology, psychology, religion, politics, art, or any other major area of study, this type of speech can be very useful in helping people to understand complex ideas.

The fifth type of informative speech involves processes. The process speech can be divided into two unique types: how-it-functions and how-to-do. The first type of process speech helps audience members understand how a specific object or system works. For example, you could explain how a bill becomes a law in the United States. There is a very specific set of steps that a bill must go through before it becomes a law, so there is a very clear process that could be explained to an audience. The how-to-do speech, on the other hand, is designed to help people come to an end result of some kind. For example, you could give a speech on how to quilt, how to change a tire, how to write a résumé, and millions of other how-to oriented topics. In our experience, the how-to speech is probably the most commonly delivered informative speech in public speaking classes.

The final type of informative speech involves issues, or “problems or matters of dispute” (O’Hair, et al., 2007). This informative speech topic is probably the most difficult for novice public speakers because it requires walking a fine line between informing and persuading. If you attempt to deliver this type of speech, remember the goal is to be balanced when discussing both sides of the issue. To see an example of how you can take a very divisive topic and make it informative, check out the series Point/Counterpoint published by Chelsea House, http://chelseahouse.infobasepublishing.com . This series of books covers everything from the pros and cons of blogging to whether the United States should have mandatory military service.

Sample: Jessy Ohl’s Informative Speech

The following text represents an informative speech prepared and delivered by an undergraduate student named Jessy Ohl. While this speech is written out as a text for purposes of analysis, in your public speaking course, you will most likely be assigned to speak from an outline or notes, not a fully written script. As you read through this sample speech, notice how Ms. Ohl uses informative strategies to present the information without trying to persuade her audience.

In 1977, a young missionary named Daniel Everett traveled deep into the jungles of Brazil to spread the word of God. However, he soon found himself working to translate the language of a remote tribe that would ultimately change his faith, lead to a new profession, and pit him in an intellectual fistfight with the world-famous linguist Noam Chomsky. As New Scientist Magazine of January 2008 explains, Everett’s research on a small group of 350 people called the Pirahã tribe has revealed a language that has experts and intellectuals deeply disturbed. While all languages are unique, experts like Noam Chomsky have argued that they all have universal similarities, such as counting, that are hard-wired into the human brain. So as National Public Radio reported on April 8, 2007, without the ability to count, conceptualize time or abstraction, or create syntax, the Pirahã have a language that by all accounts shouldn’t exist. Daniel Everett is now a professor of linguistics at Illinois State University, and he has created controversy by calling for a complete reevaluation of all linguistic theory in light of the Pirahã. Exploration of the Pirahã could bring further insight into the understanding of how people communicate and even, perhaps, what it means to be human. Which is why we must: first, examine the unique culture of the Pirahã; second, explore what makes their language so surprising; and finally, discover the implications the Pirahã have for the way we look at language and humanity. Taking a closer look at the tribe’s culture, we can identify two key components of Pirahã culture that help mold language: first, isolation; and second, emphasis on reality. First, while globalization has reached nearly every corner of the earth, it has not been able to penetrate the Pirahã natives in the slightest. As Dr. Everett told the New Yorker of April 16, 2007, no group in history has resisted change like the Pirahã. “They reject everything from outside their world” as unnecessary and silly. Distaste for all things foreign is the reason why the people have rejected technology, farming, religion, and even artwork. The lack of artwork illustrates the second vital part of Pirahã culture: an emphasis on reality. According to the India Statesman of May 22, 2006, all Pirahã understanding is based around the concept of personal experience. If something cannot be felt, touched, or experienced directly then to them, it doesn’t exist, essentially eliminating the existence of abstract thought. Since art is often a representation of reality, it has no value among the people. During his work as a missionary, Everett was amazed to find that the natives had no interest in the story of Jesus once they found out that he was dead. The Pirahã psyche is so focused on the present that the people have no collective memory, history, written documents, or creation myths. They are unable to even remember the names of dead grandparents because once something or someone cannot be experienced, they are no longer important. Since his days as a missionary, Everett remains the only Western professor able to translate Pirahã. His research has discovered many things missing with the language: words for time, direction, and color. But more importantly, Pirahã also lacks three characteristics previously thought to be essential to all languages: complexity, counting, and recursion. First, the Pirahã language seems incredibly simple. Now, this isn’t meant to imply that the people are uncivilized or stupid, but instead, they are minimalist. As I mentioned earlier, they only talk in terms of direct experience. The London Times of January 13, 2007, notes that with only eight consonants and three vowels, speakers rely on the use of tone, pitch, and humming to communicate. In fact, Pirahã almost sounds more like song than speech.

Second, Noam Chomsky’s famous universal grammar theory includes the observation that every language has a means of counting. However, as reported in the June 2007 issue of Prospect Magazine , the Pirahã only have words for “one, two, and MANY.” This demonstrates the Pirahã’s inability to conceptualize a difference between three and five or three and a thousand. Dr. Everett spent six months attempting to teach even a single Pirahã person to count to ten, but his efforts were in vain, as tribal members considered the new numbers and attempts at math “childish.” Third, and the biggest surprise for researchers, is the Pirahã’s apparent lack of recursion. Recursion is the ability to link several thoughts together. It is characterized in Christine Kenneally’s 2007 book, The Search for the Origins of Language , as the fundamental principle of all language and the source of limitless expression. Pirahã is unique since the language does not have any conjunctions or linking words. Recursion is so vital for expression that the Chicago Tribune of June 11, 2007, reports that a language without recursion is like disproving gravity. Although the Pirahã don’t care what the outside world thinks of them, their language and world view has certainly ruffled feathers. And while civilization hasn’t been able to infiltrate the Pirahã, it may ultimately be the Pirahã that teaches civilization a thing or two, which brings us to implications on the communicative, philosophical, and cultural levels. By examining the culture, language, and implications of the Pirahã tribe we are able to see how this small Brazilian village could shift the way that we think and talk about the world. Daniel Everett’s research hasn’t made him more popular with his colleagues. But his findings do show that more critical research is needed to make sure that our understanding of language is not lost in translation.

To Persuade

The second general purpose people can have for speaking is to persuade. In persuasive speaking , we attempt to get listeners to embrace a point of view or to adopt a behavior that they would not have done otherwise. A persuasive speech is distinguished from an informative speech by the fact that it includes a call for action for the audience to make some change in their behavior or thinking.

Why We Persuade

The reasons behind persuasive speaking fall into two main categories, which we will call “pure persuasion” and “manipulative persuasion.” Pure persuasion occurs when a speaker urges listeners to engage in a specific behavior or change a point of view because the speaker truly believes that the change is in the best interest of the audience members. For example, you may decide to give a speech on the importance of practicing good oral hygiene because you genuinely believe that oral hygiene is essential and that bad oral hygiene can lead to a range of physical, social, and psychological problems. In this case, the speaker has no ulterior or hidden motive (e.g. you are not a toothpaste salesperson).

Manipulative persuasion occurs when a speaker urges listeners to engage in a specific behavior or change a point of view by misleading them, often to fulfill an ulterior motive beyond the face value of the persuasive attempt. We call this form of persuasion manipulative because the speaker is not being honest about the real purpose of attempting to persuade the audience. Ultimately, this form of persuasion is perceived as profoundly dishonest when audience members discover the ulterior motive. For example, suppose a physician who also owns a large amount of stock in a pharmaceutical company is asked to speak before a group of other physicians about a specific disease. Instead of informing the group about the illness, the doctor spends the bulk of his time attempting to persuade the audience that the drug his company manufactures is the best treatment for that specific disease.

Obviously, the critical question for persuasion is the speaker’s intent. Is the speaker attempting to persuade the audience because of a sincere belief in the benefits of a certain behavior or point of view? Or is the speaker using all possible means—including distorting the truth—to persuade the audience because they will derive personal benefits from their adopting a specific behavior or point of view? Unless your speech assignment calls explicitly for a speech of manipulative persuasion, the usual (and ethical) understanding of a “persuasive speech” assignment is that you should use the pure form of persuasion.

Persuasive speaking attempts to get listeners to embrace a point of view or to adopt a behavior that they would not have done otherwise.

Pure persuasion occurs when a speaker urges listeners to engage in a specific behavior or change a point of view because the speaker truly believes that the change is in the best interest of the audience members.

Persuasion: Behavior versus Attitudes, Values, and Beliefs

Persuasion can address behaviors, observable actions on the part of listeners, and it can also address intangible thought processes in the form of attitudes, values, and beliefs.

When the speaker attempts to persuade an audience to change their behavior , or observable actions on the part of listeners. We can often observe and even measure how successful the persuasion was. For example, after a speech attempting to persuade the audience to donate money to a charity, the charity can measure how many donations were received. The following is a short list of various behavior-oriented persuasive speeches we’ve seen in our own classes: washing one’s hands frequently and using hand sanitizer, adapting one’s driving habits to improve gas mileage, using open-source software, or drinking one soft drink or soda over another. In all these cases, the goal is to make a change in the basic behavior of audience members.

The second type of persuasive topic involves a change in attitudes, values, or beliefs. An attitude is defined as an individual’s general predisposition toward something as being good or bad, right or wrong, negative or positive. If you believe that dress codes on college campuses are a good idea, you want to give a speech persuading others to adopt a positive attitude toward campus dress codes.

A speaker can also attempt to persuade listeners to change some value they hold. Value refers to an individual’s perception of the usefulness, importance, or worth of something. We can value a college education, we can value technology, and we can value freedom. Values, as a general concept, are relatively ambiguous and tend to be very lofty ideas. Ultimately, what we value in life motivates us to engage in a range of behaviors. For example, if you value protecting the environment, you may recycle more of your trash than someone who does not hold this value. If you value family history and heritage, you may be more motivated to spend time with your older relatives and ask them about their early lives than someone who does not hold this value.

Lastly, a speaker can attempt to persuade people to change their personal beliefs. Personal b eliefs are propositions or positions that an individual holds as true or false without positive knowledge or proof. Typically, beliefs are divided into two basic categories: core and dispositional. Core beliefs are beliefs that people have actively engaged in and created over the course of their lives (e.g. belief in a higher power, belief in extraterrestrial life forms). Dispositional beliefs , on the other hand, are beliefs that people have not actively engaged in; they are judgments based on related subjects, which people make when they encounter a proposition. Imagine, for example, that you were asked the question, “Can gorillas speak English?” While you may never have met a gorilla or even seen one in person, you can make instant judgments about your understanding of gorillas and fairly certainly say whether you believe that gorillas can speak English.

When it comes to persuading people to alter beliefs, persuading audiences to change core beliefs is more difficult than persuading audiences to alter dispositional beliefs. If you find a topic related to dispositional beliefs, using your speech to help listeners alter their processing of the belief is a realistic possibility. But as a novice public speaker, you are probably best advised to avoid core beliefs. Although core beliefs often appear to be more exciting and interesting than dispositional ones, you are very unlikely to alter anyone’s core beliefs in a five- to ten-minute classroom speech.

Attitude is defined as an individual’s general predisposition toward something as being good or bad, right or wrong, negative or positive.

Value refers to an individual’s perception of the usefulness, importance, or worth of something.

Core beliefs are beliefs that people have actively engaged in and created over the course of their lives (e.g. belief in a higher power, belief in extraterrestrial life forms).

Dispositional beliefs are beliefs that people have not actively engaged in; they are judgments based on related subjects, which people make when they encounter a proposition.

Sample: Jessy Ohl’s Persuasive Speech

The following speech was written and delivered by an undergraduate student named Jessy Ohl. As with our earlier example, while this speech is written out as a text for purposes of analysis, in your public speaking course, you will most likely be assigned to speak from an outline or notes, not a fully written script.

Take a few minutes and compare this persuasive speech to the informative speech Ms. Ohl presented earlier in this chapter. What similarities do you see? What differences do you see? Does this speech seek to change the audience’s behavior? Attitudes? Values? Dispositional or core beliefs? Where in the speech do you see one or more calls for action?

With a declining population of around 6,000, my home town of Denison, Iowa, was on the brink of extinction when a new industry rolled in bringing jobs and revenue. However, as the Canadian Globe and Mail of July 23, 2007, reports, the industry that saved Denison may ultimately lead to its demise. Denison is one of 110 communities across the country to be revolutionized by the production of corn ethanol. Ethanol is a high-powered alcohol, derived from plant matter, that can be used like gasoline. According to the Omaha World Herald of January 8, 2008, our reliance on foreign oil combined with global warming concerns have many holding corn ethanol as our best energy solution. But despite the good intentions of helping farmers and lowering oil consumption, corn ethanol is filled with empty promises. In fact, The Des Moines Register of March 1, 2008, concludes that when ethanol is made from corn, all of its environmental and economic benefits disappear. With oil prices at 100 dollars per barrel, our nation is in an energy crisis, and luckily, the production of ethanol can be a major help for both farmers and consumers, if done correctly. Unfortunately, the way we make ethanol—over 95% from corn—is anything but correct. Although hailed as a magic bullet, corn ethanol could be the worst agricultural catastrophe since the Dust Bowl. The serious political, environmental, and even moral implications demand that we critically rethink this so-called yellow miracle by: first, examining the problems created by corn ethanol; second, exploring why corn ethanol has gained such power; and finally, discovering solutions to prevent a corn ethanol disaster. Now, if you have heard anything about the problems of corn ethanol, it probably dealt with efficiency. As the Christian Science Monitor of November 15, 2007, notes, it takes a gallon of gasoline or more to make a gallon of ethanol. And while this is an important concern, efficiency is the least of our worries. Turning this crop into fuel creates two major problems for our society: first, environmental degradation; and second, acceleration of global famine. First, corn ethanol damages the environment as much as, if not more than, fossil fuels. The journal Ethanol and Bio-diesel News of September 2007 asserts that the production of corn ethanol is pushing natural resources to the breaking point. Since the Dust Bowl, traditional farming practices have required farmers to “rotate” crops. But with corn ethanol being so profitable, understandably, farmers have stopped rotating crops, leading to soil erosion, deforestation, and fertilizer runoff—making our soil less fertile and more toxic. And the story only gets worse once the ethanol is manufactured. According to National Public Radio’s Talk of the Nation of February 10, 2008, corn ethanol emits more carbon monoxide and twice the amount of carcinogens into the air as traditional gasoline. The second problem created from corn ethanol is the acceleration of global famine. According to the US Grains Council, last year, 27 million tons of corn, traditionally used as food, was turned into ethanol, drastically increasing food prices. The March 7, 2007, issue of The Wall Street Journal explains that lower supplies of corn needed for necessities such as farm feed, corn oil, and corn syrup have increased our food costs in everything from milk to bread, eggs, and even beer as much as 25 percent. The St. Louis Post Dispatch of April 12, 2007, reports that the amount of corn used to fill one tank of gas could feed one person for an entire year. In October, Global protests over corn ethanol lead the United Nations to call its production “a crime against humanity.” If you weren’t aware of the environmental or moral impacts of corn ethanol, you’re not alone. The Financial Times of May 27, 2007, reports that the narrative surrounding corn ethanol as a homegrown fuel is so desirable that critical thinking is understandably almost nonexistent. To start thinking critically about corn ethanol, we need to examine solutions on both the federal and personal levels. First, at the federal level, our government must end the ridiculously high subsidies surrounding corn ethanol. On June 24, 2007, The Washington Post predicted that subsidies on corn ethanol would cost the federal government an extra 131 billion dollars by 2010. This isn’t to say that the federal government should abandon small farmers. Instead, let’s take the excitement around alternative fuels and direct it toward the right kinds of ethanol. The Economist of June 2, 2007, reports that other materials such as switch grass and wood chips can be used instead of corn. And on July 6, 2011, The New York Times reported on ethanol made from corn cobs, leaves, and husks, which leaves the corn kernels to be used as food. The government could use the money paid in subsidies to support this kind of responsible production of ethanol. The point is that ethanol done right can honestly help with energy independence. On the personal level, we have all participated in the most important step, which is being knowledgeable about the true face of corn ethanol. However, with big business and Washington proclaiming corn ethanol’s greatness, we need to spread the word. So please, talk to friends and family about corn ethanol while there is still time. To make this easier, visit my website, at http://www.responsibleethanol.com . Here you will find informational materials, links to your congressional representatives, and ways to invest in switch grass and wood ethanol. Today, we examined the problems of corn ethanol in America and discovered solutions to make sure that our need for energy reform doesn’t sacrifice our morality. Iowa is turning so much corn into ethanol that soon the state will have to import corn to eat. And while my hometown of Denison has gained much from corn ethanol, we all have much more to lose from it.

To Entertain

The final general purpose people can have for public speaking is to entertain. Whereas informative and persuasive speech making is focused on the end result of the speech process, entertainment speaking focuses on the theme and occasion of the speech. An entertaining speech can be either informative or persuasive at its root, but the context or theme of the speech requires speakers to think about the speech primarily in terms of audience enjoyment.

Why We Entertain

Entertaining speeches are very common in everyday life. The fundamental goal of an entertaining speech is audience enjoyment, which can come in a variety of forms. Entertaining speeches can be funny or serious. Overall, entertaining speeches are not designed to give an audience a deep understanding of life but instead to function as a way to divert an audience from their day-to-day lives for a short period of time. This is not to say that an entertaining speech cannot have real content that is highly informative or persuasive, but its goal is primarily about the entertaining aspects of the speech and not focused on the informative or persuasive quality of the speech.

Common Forms of Entertainment Topics

There are three basic types of entertaining speeches: the after-dinner speech, the ceremonial speech, and the inspirational speech. The after-dinner speaking is a form of speaking where a speaker takes a serious speech topic (either informative or persuasive) and injects a level of humor into the speech to make it entertaining. Some novice speakers will attempt to turn an after-dinner speech into a stand-up comedy routine, which doesn’t have the same focus (Roye, 2010). After-dinner speeches are first and foremost speeches.

A ceremonial speech is a type of entertaining speech where the specific context of the speech is the driving force of the speech. Common types of ceremonial speeches include introductions, toasts, and eulogies. In each of these cases, there are specific events that drive the speech. Maybe you’re introducing an individual who is about to receive an award, giving a toast at your best friend’s wedding, or delivering the eulogy at a relative’s funeral. In each of these cases, the speech and the purpose of the speech is determined by the context of the event and not by the desire to inform or persuade.

The final type of entertaining speech, an inspirational speech , is one where the speaker’s primary goal is to inspire her or his audience. Inspirational speeches are based on emotions with the goal to motivate listeners to alter their lives in some significant way. Florence Littauer, a famous professional speaker, delivers an emotionally charged speech titled “ Silver Boxes .” In the speech, Mrs. Littauer demonstrates how people can use positive comments to encourage others in their daily lives. The title comes from a story she tells at the beginning of the speech where she was teaching a group of children about using positive speech, and one of the children defined positive speech as giving people little silver boxes with bows on top ( http://server.firefighters.org/catalog/2009/45699.mp3 ).

Sample: Adam Fink’s Entertainment Speech

The following speech, by an undergraduate student named Adam Fink, is an entertainment speech. Specifically, this speech is a ceremonial speech given at Mr. Fink’s graduation. As with our earlier examples, while this speech is written out as a text for purposes of analysis, in your public speaking course you will most likely be assigned to speak from an outline or notes, not a fully written script. Notice that the tenor of this speech is persuasive, but it persuades in a more inspiring way than just building and proving an argument.

Good evening! I’ve spent the last few months looking over commencement speeches on YouTube. The most notable ones had eight things in common. They reflected on the past, pondered about the future. They encouraged the honorees. They all included some sort of personal story and application. They made people laugh at least fifteen times. They referred to the university as the finest university in the nation or world, and last but not least they all greeted the people in attendance. I’ll begin by doing so now. President Holst, thank you for coming. Faculty members and staff, salutations to you all. Distinguished guests, we are happy to have you. Family members and friends, we could not be here without you. Finally, ladies and gentlemen of the class of 2009, welcome to your commencement day here at Concordia University, Saint Paul, this, the finest university in the galaxy, nay, universe. Really, it’s right up there with South Harlem Institute of Technology, the School of Hard Knocks, and Harvard. Check and check! Graduates, we are not here to watch as our siblings, our parents, friends, or other family walk across this stage. We are here because today is our graduation day. I am going to go off on a tangent for a little bit. Over the past umpteen years, I have seen my fair share of graduations and ceremonies. In fact, I remember getting dragged along to my older brothers’ and sisters’ graduations, all 8,000 of them—at least it seems like there were that many now. Seriously, I have more family members than friends. I remember sitting here in these very seats, intently listening to the president and other distinguished guests speak, again saying welcome and thank you for coming. Each year, I got a little bit better at staying awake throughout the entire ceremony. Every time I would come up with something new to keep myself awake, daydreams, pinching my arms, or pulling leg hair; I was a very creative individual. I am proud to say that I have been awake for the entirety of this ceremony. I would like to personally thank my classmates and colleagues sitting around me for slapping me every time I even thought about dozing off. Personal story, check—and now, application! Graduates, don’t sleep through life. If you need a close friend or colleague to keep you awake, ask. Don’t get bored with life. In the words of one of my mentors, the Australian film director, screen writer, and producer Baz Luhrman, “Do one thing every day that scares you.” Keep yourself on your toes. Stay occupied but leave room for relaxation; embrace your hobbies. Don’t get stuck in a job you hate. I am sure many of you have seen the “Did You Know?” film on YouTube. The film montages hundreds of statistics together, laying down the ground work to tell viewers that we are approaching a crossroad. The way we live is about to change dramatically. We are living in exponential times. It’s a good thing that we are exponential people.

We are at a crossing point here, now. Each of us is graduating; we are preparing to leave this place we have called home for the past few years. It’s time to move on and flourish. But let’s not leave this place for good. Let us walk away with happy memories. We have been fortunate enough to see more change in our time here than most alumni see at their alma mater in a lifetime. We have seen the destruction of Centennial, Minnesota, and Walther. Ladies, it might not mean a lot to you, but gentlemen, we had some good times there. We have seen the building and completion of the new Residence Life Center. We now see the beginnings of our very own stadium. We have seen enough offices and departments move to last any business a lifetime. Let us remember these things, the flooding of the knoll, Ultimate Frisbee beginning at ten o’clock at night, and two back-to-back Volleyball National Championship teams, with one of those championship games held where you are sitting now. I encourage all of you to walk out of this place with flashes of the old times flickering through your brains. Reflection, check! Honorees, in the words of Michael Scott, only slightly altered, “They have no idea how high [we] can fly.” Right now you are surrounded by future politicians, film critics, producers, directors, actors, actresses, church workers, artists, the teachers of tomorrow, musicians, people who will change the world. We are all held together right here and now, by a common bond of unity. We are one graduating class. In one of his speeches this year, President Barack Obama said, “Generations of Americans have connected their stories to the larger American story through service and helped move our country forward. We need that service now.” He is right. America needs selfless acts of service. Hebrews 10:23–25 reads, “Let us hold unswervingly to the hope we profess, for he who promised is faithful. And let us consider how we may spur one another on toward love and good deeds. Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another—and all the more as you see the Day approaching.” Let us not leave this place as enemies but rather as friends and companions. Let us come back next fall for our first reunion, the Zero Class Reunion hosted by the wonderful and amazing workers in the alumni department. Let us go and make disciples of all nations, guided by His Word. Let us spread God’s peace, joy, and love through service to others. Congratulations, graduates! I hope to see you next homecoming. Encouragement, check!

Selecting a Topic

A fork in the road (a trail in the woods)

One of the most common stumbling blocks for novice public speakers is selecting their first speech topic. Generally, your public speaking instructor will provide you with some fairly specific parameters to make this a little easier. You may be assigned to tell about an event that has shaped your life or to demonstrate how to do something. Whatever your parameters, at some point you as the speaker will need to settle on a specific topic. In this section, we’re going to look at some common constraints of public speaking, picking a broad topic area, and narrowing your topic.

Common Constraints of Public Speaking

When we use the word “constraint” with regard to public speaking, we are referring to any limitation or restriction you may have as a speaker. Whether in a classroom situation or the boardroom, speakers are typically given specific instructions that they must follow. These instructions constrain the speaker and limit what the speaker can say. For example, in the professional world of public speaking, speakers are often hired to speak about a specific topic (e.g. time management, customer satisfaction, or entrepreneurship). In the workplace, a supervisor may assign a subordinate to present certain information in a meeting. In these kinds of situations, when a speaker is hired or assigned to talk about a specific topic, they cannot decide to talk about something else.

Furthermore, the speaker may have been asked to speak for an hour, only to show up and find out that the event is running behind schedule, so the speech must now be made in only thirty minutes. Having prepared sixty minutes of material, the speaker now has to determine what stays in the speech and what must go. In both of these instances, the speaker is constrained as to what they can say during a speech. Typically, we refer to four primary constraints: purpose, audience, context, and time frame.

The first major constraint someone can have involves the general purpose of the speech. As mentioned earlier, there are three general purposes: to inform, to persuade, and to entertain. If you’ve been told that you will be delivering an informative speech, you are automatically constrained from delivering a speech with the purpose of persuading or entertaining. In most public speaking classes, this is the first constraint students will come in contact with because generally, teachers will tell you the exact purpose of each speech in the class.

The second major constraint that you need to consider as a speaker is the type of audience you will have. As discussed in the chapter on audience analysis, different audiences have different political, religious, and ideological leanings. As such, choosing a speech topic for an audience that has a specific mindset can be very tricky. Unfortunately, determining what topics may or may not be appropriate for a given audience is based on generalizations about specific audiences. For example, maybe you’re going to give a speech at a local meeting of Democratic leaders. You may think that all Democrats are liberal or progressive, but there are many conservative Democrats as well. If you assume that all Democrats are liberal or progressive, you may end up offending your audience by making such a generalization without knowing better. The best way to prevent yourself from picking a topic that is inappropriate for a specific audience is to know your audience, which is why we recommend conducting an audience analysis.

The third major constraint relates to the context. For speaking purposes, the context of a speech is the set of circumstances surrounding a particular speech. There are countless different contexts in which we can find ourselves speaking: a classroom in college, a religious congregation, a corporate boardroom, a retirement village, or a political convention. In each of these different contexts, the expectations for a speaker are going to be unique and different. The topics that may be appropriate in front of a religious group may not be appropriate in the corporate boardroom. Topics appropriate for the corporate boardroom may not be appropriate at a political convention.

The last, but by no means least important, major constraint that you will face is the time frame of your speech. In speeches that are under ten minutes in length, you must narrowly focus a topic on one major idea. For example, in a ten-minute speech, you could not realistically hope to discuss the entire topic of the US Social Security program. There are countless books, research articles, websites, and other forms of media on the topic of Social Security, so trying to crystallize all that information into ten minutes is just not realistic.

Instead, narrow your topic to something that is more realistically manageable within your allotted time. You might choose to inform your audience about Social Security disability benefits, using one individual disabled person as an example. Or perhaps you could speak about the career of Robert J. Myers, one of the original architects of Social Security 1 . By focusing on information that can be covered within your time frame, you are more likely to accomplish your goal at the end of the speech.

Selecting a Broad Subject Area

Once you know what the basic constraints are for your speech, you can then start thinking about picking a topic. The first aspect to consider is what subject area you are interested in examining. A subject area is a broad area of knowledge. Art, business, history, physical sciences, social sciences, humanities, and education are all examples of subject areas. When selecting a topic, start by casting a broad net because it will help you limit and weed out topics quickly.

Furthermore, each of these broad subject areas has a range of subject areas beneath it. For example, if we take the subject area “art,” we can break it down further into broad categories like art history, art galleries, and how to create art. We can further break down these broad areas into even narrower subject areas (e.g., art history includes prehistoric art, Egyptian art, Grecian art, Roman art, Middle Eastern art, medieval art, Asian art, Renaissance art, modern art). As you can see, topic selection is a narrowing process.

Narrowing Your Topic

Narrowing your topic to something manageable for the constraints of your speech is something that takes time, patience, and experience. One of the biggest mistakes that new public speakers make is not narrowing their topics sufficiently given the constraints. In the previous section, we started demonstrating how the narrowing process works, but even in those examples, we narrowed subject areas down to fairly broad areas of knowledge.

Think of narrowing as a funnel. At the top of the funnel are the broad subject areas, and your goal is to narrow your topic further and further down until just one topic can come out the other end of the funnel. The more focused your topic is, the easier your speech is to research, write, and deliver. So let’s take one of the broad areas from the art subject area and keep narrowing it down to a manageable speech topic. For this example, let’s say that your general purpose is to inform, you are delivering the speech in class to your peers, and you have five to seven minutes. Now that we have the basic constraints, let’s start narrowing our topic. The broad area we are going to narrow in this example is Middle Eastern art. When examining the category of Middle Eastern art, the first thing you’ll find is that Middle Eastern art is generally grouped into four distinct categories: Anatolian, Arabian, Mesopotamian, and Syro-Palestinian. Again, if you’re like us, until we started doing some research on the topic, we had no idea that the historic art of the Middle East was grouped into these specific categories. We’ll select Anatolian art or the art of what is now modern Turkey.

You may think that your topic is now sufficiently narrow, but even within the topic of Anatolian art, there are smaller categories: pre-Hittite, Hittite, Urartu, and Phrygian periods of art. So let’s narrow our topic again to the Phrygian period of art (1200–700 BCE). Although we have now selected a specific period of art history in Anatolia, we are still looking at a five-hundred-year period in which a great deal of art was created. One famous Phrygian king was King Midas, who according to myth was given the ears of a donkey and the power of a golden touch by the Greek gods. As such, there is an interesting array of art from the period of Midas and its Greek counterparts representing Midas. At this point, we could create a topic about how Phrygian and Grecian art differed in their portrayals of King Midas. We now have a topic that is unique, interesting, and definitely manageable in five to seven minutes. You may be wondering how we narrowed the topic down; we just started doing a little research using the Metropolitan Museum of Art’s website ( http://www.metmuseum.org ).

Overall, when narrowing down your topic, you should start by asking yourself four basic questions based on the constraints discussed earlier in this section:

Does the topic match my intended general purpose?
Is the topic appropriate for my audience?
Is the topic appropriate for the given speaking context?
Can I reasonably hope to inform or persuade my audience in the time frame I have for the speech?

Specific Purposes

Andrew Sutherland – Roma Street Steps – CC BY-SA 2.0.

Once you have chosen your general purpose and your topic, it’s time to take your speech to the next phase and develop your specific purpose. A specific purpose starts with one of the three general purposes and then specifies the actual topic you have chosen and the basic objective you hope to accomplish with your speech. The specific purpose answers the who , what , when , where , and why questions for your speech.

Getting Specific

When attempting to get at the core of your speech (the specific purpose), you need to know a few basic things about your speech. First, you need to have a general purpose. Once you know whether your goal is to inform, persuade, or entertain, picking an appropriate topic is easier. Obviously, depending on the general purpose, you will have a range of different types of topics. For example, let’s say you want to give a speech about hygiene. You could still write a speech about hygiene no matter what your general purpose is, but the specific purpose would vary depending on whether the general purpose is to inform (discussing hygiene practices around the globe), to persuade (telling people why they need to adopt a specific hygiene practice), or to entertain (explaining some of the strange and unique hygiene practices that people have used historically). Notice that in each of these cases, the general purpose alters the topic, but all three are still fundamentally about hygiene.

Now, when discussing specific purposes, we are concerned with who, what, when, where, why, and how questions for your speech. Let’s examine each of these separately. First, you want to know who is going to be in your audience. Different audiences, as discussed in the chapter on audience analysis, have differing desires, backgrounds, and needs. Keeping your audience first and foremost in your thoughts when choosing a specific purpose will increase the likelihood that your audience will find your speech meaningful.

Second is the “what” question or the basic description of your topic. When picking an effective topic, you need to make sure that the topic is appropriate for a variety of constraints or limitations within a speaking context.

Third, you need to consider when your speech will be given. Different speeches may be better at different times of the day. For example, explaining the importance of eating breakfast and providing people with cereal bars may be a great topic at 9:00 a.m. but may not have the same impact if you’re giving it at 4:00 p.m.

Fourth, you need to consider where your speech will be delivered. Are you giving a speech in front of a classroom? A church? An executive meeting? Depending on the location of your speech, different topics may or may not be appropriate.

The last question you need to answer within your speech is why. Why does your audience need to hear your speech? If your audience doesn’t care about your specific purpose, they are less likely to pay attention to your speech. If it’s a topic that’s a little more off-the-wall, you’ll really need to think about why they should care.

Once you’ve determined the who , what , when , where , and why aspects of your topic, it’s time to start creating your actual specific purpose. First, a specific purpose, in its written form, should be a short, declarative sentence that emphasizes the main topic of your speech. Let’s look at an example:

In this example, we’ve quickly narrowed a topic from a more general topic to a more specific topic. Let’s now look at that topic in terms of a general purpose and specific purpose:

For the purpose of this example, we used the same general topic area and demonstrated how you could easily turn the topic into either an informative speech or a persuasive speech. In the first example, the speaker is going to talk about the danger embedded journalists face. In this case, the speaker isn’t attempting to alter people’s ideas about embedded journalists, just make them more aware of the dangers. In the second case, the specific purpose is to persuade a group of journalism students (the audience) to avoid jobs as embedded journalists.

Your Specific Statement of Purpose

To form a clear and succinct statement of the specific purpose of your speech, start by naming your general purpose (to inform, to persuade, or to entertain). Follow this with a capsule description of your audience (my peers in class, a group of kindergarten teachers, etc.). Then complete your statement of purpose with a prepositional phrase (a phrase using “to,” “about,” “by,” or another preposition) that summarizes your topic. As an example, “My specific purpose is to persuade the students in my residence hall to protest the proposed housing cost increase” is a specific statement of purpose, while “My speech will be about why we should protest the proposed housing cost increase” is not.

Specific purposes should be statements, not questions. If you find yourself starting to phrase your specific purpose as a question, ask yourself how you can reword it as a statement. Table 6 “My Specific Purpose Is…” provides several more examples of good specific purpose statements.

Table 6 My Specific Purpose Is…

Basic Tips for Creating Specific Purposes

Now that we’ve examined what specific purposes are, we are going to focus on a series of tips to help you write specific purposes that are appropriate for a range of speeches.

Audience, Audience, Audience

First and foremost, you always need to think about your intended audience when choosing your specific purpose. In the previous section, we talked about a speech where a speaker is attempting to persuade a group of journalism students to not take jobs as embedded journalists. Would the same speech be successful, or even appropriate, if given in your public speaking class? Probably not. As a speaker, you may think your topic is great, but you always need to make sure you think about your audience when selecting your specific purpose. For this reason, when writing your specific purpose, start off your sentence by actually listing the name of your audience: a group of journalism students, the people in my congregation, my peers in class, and so on. When you place your audience first, you’re a lot more likely to have a successful speech.

Matching the Rhetorical Situation

After your audience, the second most important consideration about your specific purpose pertains to the rhetorical situation of your speech. The rhetorical situation is the set of circumstances surrounding your speech (e.g., speaker, audience, text, and context). When thinking about your specific purpose, you want to ensure that all these components go together. You want to make sure that you are the appropriate speaker for a topic, the topic is appropriate for your audience, the text of your speech is appropriate, and the speech is appropriate for the context. For example, speeches that you give in a classroom may not be appropriate in a religious context and vice versa.

Make It Clear

The specific purpose statement for any speech should be direct and not too broad, general, or vague. Consider the lack of clarity in the following specific purpose: “To persuade the students in my class to drink more.” Obviously, we have no idea what the speaker wants the audience to drink: water, milk, orange juice? Alcoholic beverages? Furthermore, we have no way to quantify or make sense of the word “more.” “More” assumes that the students are already drinking a certain amount, and the speaker wants them to increase their intake. If you want to persuade your listeners to drink eight 8-ounce glasses of water per day, you need to say so clearly in your specific purpose.

Another way in which purpose statements are sometimes unclear comes from the use of colloquial language. While we often use colloquialisms in everyday life, they are often understood only by a limited number of people. It may sound like fun to have a specific purpose like, “To persuade my audience to get jiggy,” but if you state this as your purpose, many people probably won’t know what you’re talking about at all.

Don’t Double Up

You cannot hope to solve the entire world’s problems in one speech, so don’t even try. At the same time, you also want to make sure that you stick to one specific purpose. Chances are it will be challenging enough to inform your audience about one topic or persuade them to change one behavior or opinion. Don’t put extra stress on yourself by adding topics. If you find yourself using the word “and” in your specific topic statement, you’re probably doubling up on topics.

Can I Really Do This Speech in Five to Seven Minutes?

When choosing your specific purpose, it’s important to determine whether it can be realistically covered in the amount of time you have. Time limits are among the most common constraints for students in a public speaking course. Speeches early in the term have shorter time limits, and speeches later in the term have longer time limits. To determine whether you think you can accomplish your speech’s purpose in the time slot, ask yourself how long it would take to make you an informed person on your chosen topic or to persuade you to change your behavior or attitudes.

If you cannot reasonably see yourself becoming informed or persuaded during the allotted amount of time, chances are you aren’t going to inform or persuade your audience either. The solution, of course, is to make your topic narrower so that you can fully cover a limited aspect of it.

A specific purpose starts with one of the three general purposes and then specifies the actual topic you have chosen and the basic objective you hope to accomplish with your speech.

The rhetorical situation is the set of circumstances surrounding your speech (e.g., speaker, audience, text, and context). When thinking about your specific purpose, you want to ensure that all these components go together.

Crafting and Understanding Thesis Statements for Speeches

You might be familiar with a thesis statement in writing an essay. Thesis statements are similar in speeches, but slightly different because they are only heard and not read. To help us understand thesis statements, we will first explore their basic functions and then discuss how to write a thesis statement.

Basic Functions of a Thesis Statement

A thesis statement helps your audience by letting them know what you are going to talk about “in a nutshell.” With a good thesis statement, you will fulfill four basic functions: you express your specific purpose, provide a way to organize your main points, make your research more effective, and enhance your delivery.

Express Your Specific Purpose

To orient your audience, you need to be as clear as possible about your meaning. A strong thesis will prepare your audience effectively for the points that will follow. Here are two examples:

“Today, I want to discuss academic cheating.” (weak example)
“Today, I will clarify what plagiarism is and give examples of its different types so that you can see how it leads to a loss of creative learning interaction.” (strong example)

The weak statement will probably give the impression that you have no clear position on your topic because you haven’t said what that position is. Additionally, the term “academic cheating” can refer to many behaviors: acquiring test questions ahead of time, copying answers, changing grades, or allowing others to do your coursework. Therefore, the specific topic of the speech is still not clear to the audience. The strong statement not only specifies plagiarism but also states your specific concern (loss of creative learning interaction).

Provide a Way to Organize Your Main Points

A thesis statement should appear, almost verbatim, toward the end of the introduction to a speech. A thesis statement helps the audience get ready to listen to the arrangement of points that follow. Many speakers say that if they can create a strong thesis sentence, the rest of the speech tends to develop with relative ease. On the other hand, when the thesis statement is not very clear, creating a speech is an uphill battle. When your thesis statement is sufficiently clear and decisive, you will know where you stand on your topic and where you intend to go with your speech. Having a clear thesis statement is especially important if you know a great deal about your topic or you have strong feelings about it. If this is the case for you, you need to know exactly what you are planning on talking about in order to fit within specified time limitations. Knowing where you are and where you are going is the entire point in establishing a thesis statement; it makes your speech much easier to prepare and to present.

Let’s say you have a reasonably strong thesis statement, and that you’ve already brainstormed a list of information that you know about the topic. Chances are your list is too long and has no focus. Using your thesis statement, you can select only the information that (1) is directly related to the thesis and (2) can be arranged in a sequence that will make sense to the audience and will support the thesis. In essence, a strong thesis statement helps you keep useful information and weed out less helpful information.

Make Your Research More Effective

If you begin your research with only a general topic in mind, you run the risk of spending hours reading mountains of excellent literature about your topic. However, mountains of research does not always make coherent speeches.

You may have little or no idea of how to tie your research together, or even whether you should tie it together. If, on the other hand, you conduct your research with a clear thesis statement in mind, you will be better able to zero in only on material that directly relates to your chosen thesis statement. Let’s look at an example that illustrates this point:

Many traffic accidents involve drivers older than fifty-five. While this statement may be true, you could find industrial, medical, insurance literature that can drone on ad infinitum about the details of all such accidents in just one year. Instead, focusing your thesis statement will help you narrow the scope of information you will be searching for while gathering information.

Here’s an example of a more focused thesis statement:

Three factors contribute to most accidents involving drivers over fifty-five years of age: failing eyesight, slower reflexes, and rapidly changing traffic conditions.

Mature drivers over fifty-five years of age must cope with more challenging driving conditions than existed only one generation ago: more traffic moving at higher speeds, the increased imperative for quick driving decisions, and rapidly changing ramp and cloverleaf systems. Because of these challenges, I want my audience to believe that drivers over the age of sixty-five should be required to pass a driving test every five years.

Enhance Your Delivery

When your thesis is not clear to you, your listeners will be even more clueless than you are. However, if you have a good clear thesis statement, your speech becomes clear to your listeners. When you stand in front of your audience presenting your introduction, you can vocally emphasize the essence of your speech, expressed as your thesis statement.

Many speakers pause for a half second, lower their vocal pitch slightly, slow down a little, and deliberately present the thesis statement, the one sentence that encapsulates its purpose. When this is done effectively, the purpose, intent, or main idea of a speech is driven home for an audience.

How to Write a Thesis Statement

Now that we’ve looked at why a thesis statement is crucial in a speech, let’s switch gears and talk about how we go about writing a solid thesis statement.

Choose Your Topic

The first step in writing a good thesis statement is finding your topic. Once you have a general topic, you are ready to go to the second step of creating a thesis statement.

Narrow Your Topic

One of the hardest parts of writing a thesis statement is narrowing a speech from a broad topic to one that can be easily covered during a five- to ten-minute speech. While five to ten minutes may sound like a long time to new public speakers, the time flies by very quickly when you are speaking. You can run out of time if your topic is too broad. To decide if your topic is narrow enough for a specific time frame, ask yourself three questions:

First, is your thesis statement narrow or is it a broad overgeneralization of a topic? Overgeneralization occurs when we classify everyone in a specific group as having a specific characteristic. For example, a speaker’s thesis statement that “the elderly are bad drivers” is an overgeneralization of all elderly drivers. Make sure that your thesis statement is nuanced enough to accurately represent what you can support in your speech.

The second question to ask yourself when narrowing a topic is whether your speech’s topic is one clear topic or multiple topics. A strong thesis statement consists of only a single topic. The following is an example of a thesis statement that contains too many topics: “Medical marijuana and prostitution should be legalized in the United States.” Not only are both broad, but you also have two completely unrelated topics thrown into a single thesis statement. Instead of a thesis statement that has multiple topics, limit yourself to only one topic. Here’s an example of a thesis statement examining only one topic: “Today we’re going to examine the legalization and regulation of prostitution in the state of Nevada.” In this case, we’re focusing our topic on how one state has handled the legalization and regulation of prostitution.

The last question a speaker should ask when making sure a topic is sufficiently narrow is whether the topic has direction. If your basic topic is too broad, you will never have a solid thesis statement or a coherent speech. For example, if you start off with the topic “Barack Obama is a role model for everyone,” what do you mean by this statement? Do you think President Obama is a role model because of his dedication to civic service? Do you think he’s a role model because he’s a good basketball player? Do you think he’s a good role model because he’s an excellent public speaker? When your topic is too broad, almost anything can become part of the topic. This broadness ultimately leads to a lack of direction and coherence within the speech itself. To make a cleaner topic, a speaker needs to narrow their topic to one specific area. For example, you may want to examine why President Obama is a good speaker.

Put Your Topic into a Sentence

Use the Thesis Checklist

Once you have written the first draft of your thesis statement, you’re probably going to end up revising your thesis statement a number of times before delivering your actual speech. A thesis statement is something that is constantly tweaked until the speech is given. As your speech develops, often your thesis will need to be rewritten to whatever direction the speech itself has taken. We often start with a speech going in one direction and find out through our research that we should have gone in a different direction. When you think you finally have a thesis statement that is good to go for your speech, take a second and make sure it adheres to the criteria shown below.

Thesis Checklist

Instructions: For each of the following questions, check either “yes” or “no.” Yes No

Does your thesis clearly reflect the topic of your speech?
Can you adequately cover the topic indicated in your thesis within the time you have for your speech?
Is your thesis statement simple?
Is your thesis statement direct?
Does your thesis statement gain an audience’s interest?
Is your thesis statement easy to understand?
Does your thesis statement introduce a clear argument?
Does your thesis statement clearly indicate what your audience should know, do, think, or feel?

Scoring: For a strong thesis statement, all your answers should have been “yes.”

After reading this chapter, we hope that you now have a better understanding not only of the purpose of your speech but also of how to find a fascinating topic for yourself and your audience. We started this chapter citing lyrics from the Avenue Q song “Purpose.” While the character is trying to find his purpose in life, we hope this chapter has helped you identify your general purpose, choose a topic that will interest you and your audience, and use these to develop a specific purpose statement for your speech.

8.2 The Topic, General Purpose, Specific Purpose, and Thesis

Before any work can be done on crafting the body of your speech or presentation, you must first do some prep work—selecting a topic, formulating a general purpose, a specific purpose statement, and crafting a central idea, or thesis statement. In doing so, you lay the foundation for your speech by making important decisions about what you will speak about and for what purpose you will speak. These decisions will influence and guide the entire speechwriting process, so it is wise to think carefully and critically during these beginning stages.

Understanding the General Purpose

Before any work on a speech can be done, the speaker needs to understand the general purpose of the speech. The general purpose is what the speaker hopes to accomplish and will help guide in the selection of a topic. The instructor generally provides the general purpose for a speech, which falls into one of three categories. A general purpose to inform would mean that the speaker is teaching the audience about a topic, increasing their understanding and awareness, or providing new information about a topic the audience might already know. Informative speeches are designed to present the facts, but not give the speaker’s opinion or any call to action. A general purpose to persuade would mean that the speaker is choosing the side of a topic and advocating for their side or belief. The speaker is asking the audience to believe in their stance, or to take an action in support of their topic. A general purpose to entertain often entails short speeches of ceremony, where the speaker is connecting the audience to the celebration. You can see how these general purposes are very different. An informative speech is just facts, the speaker would not be able to provide an opinion or direction on what to do with the information, whereas a persuasive speech includes the speaker’s opinions and direction on what to do with the information. Before a speaker chooses a topic, they must first understand the general purpose.

Selecting a Topic

What important events are occurring locally, nationally, and internationally?
What do I care about most?
Is there someone or something I can advocate for?
What makes me angry/happy?
What beliefs/attitudes do I want to share?
Is there some information the audience needs to know?

Students speak about what is interesting to them and their audiences. What topics do you think are relevant today? There are other questions you might ask yourself, too, but these should lead you to at least a few topical choices. The most important work that these questions do is to locate topics within your pre-existing sphere of knowledge and interest. Topics should be ideas that interest the speaker or are part of their daily lives. In order for a topic to be effective, the speaker needs to have some credibility or connection to the topic; it would be unfair to ask the audience to donate to a cause that the speaker has never donated to. There must be a connection to the topic for the speaker to be seen as credible. David Zarefsky (2010) also identifies brainstorming as a way to develop speech topics, a strategy that can be helpful if the questions listed above did not yield an appropriate or interesting topic. Brainstorming involves looking at your daily activities to determine what you could share with an audience. Perhaps if you work out regularly or eat healthy, you could explain that to an audience, or demonstrate how to dribble a basketball. If you regularly play video games, you may advocate for us to take up video games or explain the history of video games. Anything that you find interesting or important might turn into a topic. Starting with a topic you are already interested in will make writing and presenting your speech a more enjoyable and meaningful experience. It means that your entire speechwriting process will focus on something you find important and that you can present this information to people who stand to benefit from your speech. At this point, it is also important to consider the audience before choosing a topic. While we might really enjoy a lot of different things that could be topics, if the audience has no connection to that topic, then it wouldn’t be meaningful for the speaker or audience. Since we always have a diverse audience, we want to make sure that everyone in the audience can gain some new information from the speech. Sometimes, a topic might be too complicated to cover in the amount of time we have to present, or involve too much information then that topic might not work for the assignment, and finally if the audience can not gain anything from a topic then it won’t work. Ultimately, when we choose a topic we want to pick something that we are familiar with and enjoy, we have credibility and that the audience could gain something from. Once you have answered these questions and narrowed your responses, you are still not done selecting your topic. For instance, you might have decided that you really care about breeds of dogs. This is a very broad topic and could easily lead to a dozen different speeches. To resolve this problem, speakers must also consider the audience to whom they will speak, the scope of their presentation, and the outcome they wish to achieve.

Formulating the Purpose Statements

By honing in on a very specific topic, you begin the work of formulating your purpose statement. In short, a purpose statement clearly states what it is you would like to achieve. Purpose statements are especially helpful for guiding you as you prepare your speech. When deciding which main points, facts, and examples to include, you should simply ask yourself whether they are relevant not only to the topic you have selected, but also whether they support the goal you outlined in your purpose statement. The general purpose statement of a speech may be to inform, to persuade, to celebrate, or to entertain. Thus, it is common to frame a specific purpose statement around one of these goals. According to O’Hair, Stewart, and Rubenstein, a specific purpose statement “expresses both the topic and the general speech purpose in action form and in terms of the specific objectives you hope to achieve” (2004). The specific purpose is a single sentence that states what the audience will gain from this speech, or what will happen at the end of the speech. The specific purpose is a combination of the general purpose and the topic and helps the speaker to focus in on what can be achieved in a short speech.

To go back to the topic of a dog breed, the general purpose might be to inform, a specific purpose might be: To inform the audience about how corgis became household pets. If the general purpose is to persuade the specific purpose might be: to persuade the audience that dog breeds deemed “dangerous” should not be excluded from living in the cities. In short, the general purpose statement lays out the broader goal of the speech while the specific purpose statement describes precisely what the speech is intended to do. The specific purpose should focus on the audience and be measurable, if I were to ask the audience before I began the speech how many people know how corgis became household pets, they could raise their hand, and if I ask at the end of my speech how many people know how corgis became household pets, I should see a lot more hands. The specific purpose is the “so what” of the speech, it helps the speaker focus on the audience and take a bigger idea of a topic and narrow it down to what can be accomplished in a short amount of time.

Writing the Thesis Statement

The specific purpose statement is a tool that you will use as you write your speech, but it is unlikely that it will appear verbatim in your speech. Instead, you will want to convert the specific purpose statement into a central idea, or thesis statement that you will share with your audience. Just like in a written paper, where the thesis comes in the first part of the paper, in a speech, the thesis comes within the first few sentences of the speech. The thesis must be stated and tells the audience what to expect in this speech. A thesis statement may encapsulate the main idea of a speech in just a sentence or two and be designed to give audiences a quick preview of what the entire speech will be about. The thesis statement should be a single, declarative statement followed by a separate preview statement. If you are a Harry Potter enthusiast, you may write a thesis statement (central idea) the following way using the above approach: J.K. Rowling is a renowned author of the Harry Potter series with a Cinderella-like story of a rise to fame.

Writing the Preview Statement

A preview statement (or series of statements) is a guide to your speech. This is the part of the speech that literally tells the audience exactly what main points you will cover. If you were to get on any freeway, there would be a green sign on the side of the road that tells you what cities are coming up—this is what your preview statement does; it tells the audience what points will be covered in the speech. Best of all, you would know what to look for! So, if we take our J.K Rowling example, the thesis and preview would look like this: J.K. Rowling is a renowned author of the Harry Potter series with a Cinderella-like rags-to-riches story. First, I will tell you about J.K. Rowling’s humble beginnings. Then, I will describe her personal struggles as a single mom. Finally, I will explain how she overcame adversity and became one of the richest women in the United Kingdom.

Writing the Body of Your Speech

Once you have finished the important work of deciding what your speech will be about, as well as formulating the purpose statement and crafting the thesis, you should turn your attention to writing the body of your speech. The body of your speech consists of 3–4 main points that support your thesis and help the audience to achieve the specific purpose. Creating main points helps to chunk the information you are sharing with your audience into an easy-to-understand organization. Choosing your main points will help you focus in on what information you want to share with the audience in order to prove your thesis. Since we can’t tell the audience everything about our topic, we need to choose our main points to make sure we can share the most important information with our audience. All of your main points are contained in the body, and normally this section is prepared well before you ever write the introduction or conclusion. The body of your speech will consume the largest amount of time to present, and it is the opportunity for you to elaborate on your supporting evidence, such as facts, statistics, examples, and opinions that support your thesis statement and do the work you have outlined in the specific purpose statement. Combining these various elements into a cohesive and compelling speech, however, is not without its difficulties, the first of which is deciding which elements to include and how they ought to be organized to best suit your purpose.

Arguments and Information

Learning Objectives

Define what an argument is
Introduce ethos, pathos, and logos
Identify the argument structure of claim, evidence, and warrant
Explore effective language

You may be wondering, “What exactly is an argument? Haven’t I already decided on my main argument and topic?”

An argument is a series of statements in support of a claim, assertion, or proposition. So far, we’ve discussed thesis statements as the main argumentative through-line for a speech—it’s what you want to inform, persuade, or entertain the audience about.

Your thesis statement, however, is just one component of an argument, i.e. “here’s what I want to inform you about / persuade you to consider.” It is the main claim of your speech. Your task is to prove the reliability of that claim (with evidence) and demonstrate, through the body of the speech, how or why that information should matter to the audience. In this chapter, we will fill in the other structural components of an argument to make sure that your thesis statement has adequate support and proof. We’ll also outline the importance of language and tips to guarantee that your language increases the effective presentation of your argument.

An Overview of Arguments

It may be tempting to view arguments as only relevant to persuasion or persuasive speeches. After all, we commonly think of arguments as occurring between different perspectives or viewpoints with the goal of changing someone’s mind. Arguments are important when persuading (and we will re-visit persuasive arguments in Chapter 13), but you should have clear evidence and explanations for any type of information sharing.

All speech types require proof to demonstrate the reliability of their claims. Remember, when you speak, you are being an advocate and selecting information that you find relevant to your audience, so arguments are necessary to, at a bare minimum, build in details about the topic’s importance.

With speeches that primarily inform, a sound argument demonstrates the relevance and significance of the topic for your audience. In other words, “this is important information because…” or “here’s why you should care about this.” If you are giving a ceremonial speech, you should provide examples of your insights. In a speech of introduction, for example, you may claim that the speaker has expertise, but you should also provide evidence of their previous accomplishments and demonstrate why those accomplishments are significant.

For each speech type, a well-crafted speech will have multiple arguments throughout. Yes, your thesis statement is central to speech, and your content should be crafted around that idea – you will use your entire speech to prove the reliability of that statement. You will also have internal arguments, i.e. your speech’s main points or the “meat” of your speech.

All speech types require arguments, and all arguments use the rhetorical appeals of ethos, pathos, and logos to elicit a particular feeling or response from your audience.

Ethos , or establishing your credibility as a speaker, is necessary for any speech. If you’re informing the audience about a key topic, they need to know that you’re a trustworthy and reliable speaker. A key way to prove that credibility is through crafting arguments that are equally credible. Using reliable and well-tested evidence is one way to establish ethos.

Using reason or logic, otherwise known as logos , is also a key rhetorical appeal. By using logos, you can select logical evidence that is well-reasoned, particularly when you’re informing or persuading. We’ll talk more about logic and fallacies (to avoid) in Chapter 13.

Pathos , or emotional appeals, allows you to embed evidence or explanations that pull on your audience’s heartstrings or other feelings and values. Pathos is common in ceremonial speeches, particularly speeches that eulogize or celebrate a special occasion.

All three rhetorical appeals are important mechanisms to motivate your audience to listen or act. All three should be done ethically (see Chapter 1) and with the speech context and audience in mind.

Regardless of which rhetorical proof you use, your arguments should be well-researched and well-structured. Below, we explore the structure of an argument in more detail.

The Structur e : Claim, Evidence, Warrant

Arguments have the following basic structure (see Figure 5.1):

Claim: the main proposition crafted as a declarative statement.
Evidence: the support or proof for the claim.
Warrant: the connection between the evidence and the claim.

Each component of the structure is necessary to formulate a compelling argument.

The Toulmin Model

British Philosopher, Stephen Toulmin, created the “Toulmin Model” – a model that describes the structure of an argument or method of reasoning. Claim, evidence, and warrant are, if done well, necessary to create a good argument (O’Connor, 1958).

Visual layout of claim, evidence, and warrant

Evidence and warrants are the specifics that make your ideas, arguments, assertions, points, or concepts real and concrete by relating the information to your audience. Not all audiences are compelled by the same evidence, for example, so creating a well-structured argument also means being responsive to audiences.

Consider going to lunch with a friend. Your friend suggests a restaurant that you have not heard of, so you request some additional information, proof, or evidence of their choice. We could map the argument like this:

Claim: “Let’s go to Jack’s Shack for lunch.”
Evidence: “I have been there a few times and they have good servers.”

So far, your friend is highlighting service as the evidence to support their claim that Jack’s Shack is a good choice for lunch. However, the warrant is still missing. For a warrant, they need to demonstrate why good service is sufficient proof to support their claim. Remember that the warrant is the connection. For example:

Warrant: “You were a server, so I know that you really appreciate good service. I have never had a bad experience at Jack’s Shack, so I am confident that it’s a good lunch choice for both of us.”

In this case, they do a good job of both connecting the evidence to the claim and connecting the argument to their audience – you! They have selected evidence based on your previous experience as a server (likely in hopes to win you over to their claim!).

Using “claim, evidence, and warrant” can assist you in verifying that all parts of the argumentative structure are present. Below, we dive deeper into each category.

A claim is a declarative statement or assertion—it is something that you want your audience to accept or know. Like we’ve mentioned, your thesis statement is a key claim in your speech because it’s the main argument that you’re asking the audience to consider.

Different claims serve different purposes. Depending on the purpose of the argument, claims can be factual, opinionated, or informative. Some claims, for example, may be overtly persuading the audience to change their mind about a controversial issue, i.e. “you should support this local policy initiative.”

Alternatively, a claim may develop the significance of a topic (i.e. “this is why you should care about this information”) or highlight a key informative component about a person, place, or thing (“Hillary Clinton had an intriguing upbringing”). You might, for example, write a speech that informs the audience about college textbook affordability. Your working thesis might read, “Universities are developing textbook affordability initiatives.” Your next step would be to develop main points and locate evidence that supports your claim.

It’s important to develop confidence around writing and identifying your claims. Identifying your main ideas will allow you to then identify evidence in support of those declarative statements. If you aren’t confident about what claims you’re making, it will be difficult to identify the evidence in support of that idea, and your argument won’t be structurally complete. Remember that your thesis statement your main claim, but you likely have claims throughout your speech (like your main points).

Evidence is the proof or support for your claim. It answers the question, “how do I know this is true?” With any type of evidence, there are three overarching considerations.

First, is this the most timely and relevant type of support for my claim? If your evidence isn’t timely (or has been disproven), it may drastically influence the credibility of your claim.

Second, is this evidence relatable and clear for my audience? Your audience should be able to understand the evidence, including any references or ideas within your information. Have you ever heard a joke or insight about a television show that you’ve never seen? If so, understanding the joke can be difficult. The same is true for your audience, so stay focused on their knowledge base and level of understanding.

Third, did I cherry-pick? Avoid cherry-picking evidence to support your claims. While we’ve discussed claims first, it’s important to arrive at a claim after seeing all the evidence (i.e. doing the research). Rather than finding evidence to fit your idea (cherry-picking), the evidence should help you arrive at the appropriate claim. Cherry-picking evidence can reduce your ethos and weakened your argument.

With these insights in mind, we will introduce you to five evidence types : examples, narratives, facts, statistics, and testimony. Each provides a different type of support, and it’s suggested that you integrate a variety of different evidence types. Understanding the different types of evidence will assist as you work to structure arguments and select support that best fits the goal of your speech.

Examples are specific instances that illuminate a concept. They are designed to give audiences a reference point. An example must be quickly understandable—something the audience can pull out of their memory or experience quickly.

Evidence by example would look like this:

Claim: Textbook affordability initiatives are assisting universities in implementing reputable, affordable textbooks.

Evidence : Ohio has implemented a textbook affordability initiative, the Open Ed Collaborative, to alleviate the financial strain for students (Jaggers, Rivera, Akani, 2019).

Ohio’s affordability initiative functions as evidence by example. This example assists in demonstrating that such initiatives have been successfully implemented. Without providing an example, your audience may be skeptical about the feasibility of your claim.

Examples can be drawn directly from experience, i.e. this is a real example, or an example can be hypothetical where audiences are asked to consider potential scenarios.

Narratives are stories that clarify, dramatize, and emphasize ideas. They have, if done well, strong emotional power (or pathos). While there is no universal type of narrative, a good story often draws the audience in by identifying characters and resolving a plot issue. Narratives can be personal or historical.

Person narratives are powerful tools to relate to your audience and embed a story about your experience with the topic. As evidence, they allow you to say, “I experienced or saw this thing first hand.” As the speaker, using your own experience as evidence can draw the audience in and help them understand why you’re invested in the topic. Of course, personal narratives must be true. Telling an untrue personal narrative may negatively influence your ethos for an audience.

Historical narratives (sometimes called documented narratives) are stories about a past person, place, or thing. They have power because they can prove and clarify an idea by using a common form— the story. By “historical” we do not mean that the story refers to something that happened many years ago, only that it has happened in the past and there were witnesses to validate the happening. Historical narratives are common in informative speeches.

Facts are observations, verified by multiple credible sources, that are true or false. The National Center for Science Education (2008) defines fact as:

an observation that has been repeatedly confirmed an . . . is accepted as ‘true.’ Truth in science, however, is never final and what is accepted as a fact today may be modified or even discarded tomorrow.

“The sun is a star” is an example of a fact. It’s been observed and verified based on current scientific understanding and categorization; however, future technology may update or disprove that fact.

In our modern information age, we recommend “fact-checking a fact” because misinformation can be presented as truth. This means verifying all facts through credible research (check back to Chapter 4 on research). Avoid taking factual information for granted and make sure that the evidence comes from reputable sources that are up-to-date.

S tatistics are the collection, analysis, comparison, and interpretation of numerical data. As evidence, they are useful in summarizing complex information, quantifying, or making comparisons. Statistics are powerful pieces of evidence because numbers appear straightforward. Numbers provide evidence that quantifies, and statistics can be helpful to clarify a concept or highlighting the depth of a problem.

You may be wondering, “What does this actually mean ?” (excuse our statistical humor). We often know a statistic when we find one, but it can be tricky to understand how a statistic was derived.

Averages and percentages are two common deployments of statistical evidence.

An “ a verage ” can be statistically misleading, but it often refers to the mean of a data set. You can determine the mean (or average) by adding up the figures and dividing by the number of figures present. If you’re giving a speech on climate change, you might note that, in 2015, the average summer temperature was 97 degrees while, in 1985, it was just 92 degrees.

When using statistics, comparisons can help translate the statistic for an audience. In the example above, 97 degrees may seem hot, but the audience has nothing to compare that statistic to. The 30-year comparison assists in demonstrating a change in temperature.

A percentag e expresses a proportion of out 100. For example, you might argue that “textbook costs have risen more than 1000% since 1977” (Popken, 2015). By using a statistical percentage, 1000% sounds pretty substantial. It may be important, however, to accompany your percentage with a comparison to assist the audience in understanding that “This is 3 times higher than the normal rate of inflation” (UTA Libraries). You might also clarify that “college textbooks have risen more than any other college-related cost” (Bureau of Labor Statistics, 2016).

You are responsible for the statistical information that you deploy. It’s all too common for us as information consumers to grab a quick statistic that sounds appealing, but that information may not be reliable.

Be aware of three major statistical issues: small samples, unrepresentative samples, and correlation as causation. In a small sample, an argument is being made from too few examples. In unrepresentative sample, a conclusion is based on surveys of people who do not represent, or resemble, the ones to whom the conclusion is being applied. Finally, it’s common to conflate correlation as causation. In statistics, a correlation refers to the relationship between two variables while causation means that one variable resulted from the other. Be careful not to assume that a correlation means that something has caused the second.

A few other statistical tips:

Use statistics as support, not as a main point. The audience may cringe or tune you out for saying, “Now I’d like to give you some statistics about the problem of gangs in our part of the state.” That sounds as exciting as reading the telephone book! Use the statistics to support an argument.
In regard to sources, depend on the reliable ones. Use Chapter 4 as a guide to criticizing and evaluating credible sources.
Do not overuse statistics. While there is no hard and fast rule on how many to use, there are other good supporting materials and you would not want to depend on statistics alone. You want to choose the statistics and numerical data that will strengthen your argument the most and drive your point home. Statistics can have emotional power as well as probative value if used sparingly.
Explain your statistics as needed, but do not make your speech a statistics lesson. If you say, “My blog has 500 subscribers” to a group of people who know little about blogs, that might sound impressive, but is it? You can also provide a story of an individual, and then tie the individual into the statistic. After telling a story of the daily struggles of a young mother with multiple sclerosis, you could follow up with “This is just one story in the 400,000 people who suffer from MS in the United States today, according to National MS Society.”

Testimony is the words of others. As evidence, testimony can be valuable to gain insight into an expert or a peer’s opinion, experience, or expertise about a topic. Testimony can provide an audience with a relevant perspective that the speaker isn’t able to provide. We’ll discuss two types of testimony: expert and non-expert.

Expert Testimony

What is an expert? An expert is someone with recognized credentials, knowledge, education, and/or experience in a subject. To quote an expert on expertise, “To be an expert, someone needs to have considerable knowledge on a topic or considerable skill in accomplishing something” (Weinstein, 1993).

A campus bookstore manager could provide necessary testimony on the changing affordability of textbooks over time, for example. As someone working with instructors, students, and publishers, the manager would likely have an insight and a perspective that would be difficult to capture otherwise. They would provide unique and credible evidence.

In using expert testimony, you should follow these guidelines:

Use the expert’s testimony in their relevant field. A person may have a Nobel Prize in economics, but that does not make them an expert in biology.
Provide at least some of the expert’s relevant credentials.
If you interviewed the expert yourself, make that clear in the speech also. “When I spoke with Dr. Mary Thompson, principal of Park Lake High School, on October 12, she informed me that . . .”

Expert testimony is one of your strongest supporting materials to prove your arguments. When integrating their testimony as evidence, make sure their testimony clearly supports your claim (rather than an interesting idea on the topic that is tangential to your assertions).

Non-Expert/Peer Testimony

Any quotation from a friend, family member, or classmate about an incident or topic would be peer testimony. It is useful in helping the audience understand a topic from a personal point of view. For example, you may draw on testimony from a campus student who was unable to afford their campus textbooks. While they may lack formalized expertise in textbook affordability, their testimony might demonstrate how the high cost limited their engagement with the class. Their perspective and insight would be valuable for an audience to hear.

The third component of any argument is the warrant. Warrants connect the evidence and the claim. They often answer the question, “what does this mean?” Warrants are an important component of a complete argument because they:

Highlight the significance of the evidence;
Detail how the evidence supports the claims;
Outline the relevance of the claim and evidence to the audience.

For example, consider the claim that “communication studies provide necessary skills to land you a job.” To support that claim, you might locate a statistic and argue that, “The New York Times had a recent article stating that 80% of jobs want good critical thinking and interpersonal skills.” It’s unclear, however, how a communication studies major would prepare someone to fulfill those needs. To complete the argument, you could include a warrant that explains, “communication studies classes facilitate interpersonal skills and work to embed critical thinking activities throughout the curriculum.” You are connecting the job skills (critical thinking) from the evidence to the discipline (communication studies) from your claim.

Despite their importance, warrants are often excluded from arguments. As speechwriters and researchers, we spend lots of time with our information and evidence, and we take for granted what we know. If you are familiar with communication studies, the connection between the New York Times statistic referenced above and the assertion that communication studies provides necessary job skills may seem obvious. For an unfamiliar audience, the warrant provides more explanation and legitimacy to the evidence.

We know what you’re thinking: “Really? Do I always need an explicit warrant?”

It’s true that some warrants are inferred , meaning that we often recognize the underlying warrant without it being explicitly stated. For example, I might say, “The baking time for my cookies was too hot. The cookies burned.” In this statement, I’m claiming that the temperature is too hot and using burnt cookies as the evidence. We could reasonably infer the warrant, i.e. “burnt cookies are a sign that they were in the oven for too long.”

Inferred warrants are common in everyday arguments and conversations; however, in a formal speech, having a clear warrant will increase the clarity of your argument. If you decide that no explicit warrant is needed, it’s still necessary to ask, “what does this argument mean for my thesis? What does it mean for my audience?” Your goal is to keep as many audience members listening as possible, and warrants allow you to think critically about the information that you’re presenting to that audience.

When writing warrants, keep the following insights in mind:

Avoid exaggerating your evidence, and make sure your warrant honors what the evidence is capable of supporting;
Center your thesis statement. Remember that your thesis statement, as your main argument, should be the primary focus when you’re explaining and warranting your evidence.
A good warrant should be crafted with your content and context in mind. As you work on warrants, ask, “why is this claim/evidence important here? For this argument? Now? For this audience?”
Say it with us: ethos, pathos, and logos! Warrants can help clarify the goal of your argument. What appeal are you using? Can the warrant amplify that appeal?

Now that you have a better understanding of each component of an argument, let’s conclude this section with a few complete examples.

Claim : The Iowa Wildcats will win the championship. Evidence: In 2019, the National Sporting Association found that the Wildcats had the most consistent and well-rounded coaching staff. Referees of the game agreed, and also praised the players ability for high scoring. Warrant: Good coaching and high scoring are probable indicators of past champions and, given this year’s findings, the Wildcat’s are on mark to win it all.

Here’s an example with a more general approach to track the potential avenues for evidence:

Claim: Sally Smith will win the presidential election. Evidence: [select evidence that highlights their probable win, including: they’ve won the most primaries; they won the Iowa caucus; they’re doing well in swing states; they have raised all the money; they have the most organized campaign.” Warrant: [based on your evidence select, you can warrant why that evidence supports a presidential win].

Using Language Effectively

Claim, evidence, and warrant are useful categories when constructing or identifying a well-reasoned argument. However, a speech is much more than this simple structure over and over (how boring, huh?).

When we craft arguments, it’s tempting to view our audience as logic-seekers who rely solely on rationality, but that’s not true. Instead, Walter Fisher (1984) argues that humans are storytellers, and we make sense of the world through good stories. A good speech integrates argumentative components while telling a compelling story about your argument to the audience. A key piece of that story is how you craft the language—language aids in telling an effective story.

We’ll talk more about language in Chapter 7 (verbal delivery), but there are a few key categories to keep in mind as you construct your argument and story.

Language: What Do We Mean?

Language is any formal system of gestures, signs, sounds, and symbols used or conceived as a means of communicating thought, either through written, enacted, or spoken means. Linguists believe there are far more than 6,900 languages and distinct dialects spoken in the world today (Anderson, 2012). Despite being a formal system, language results in different interpretations and meanings for different audiences.

It is helpful for public speakers to keep this mind, especially regarding denotative and connotative meaning. Wrench, Goding, Johnson, and Attias (2011) use this example to explain the difference:

When we hear or use the word “blue,” we may be referring to a portion of the visual spectrum dominated by energy with a wave-length of roughly 440–490 nanometers. You could also say that the color in question is an equal mixture of both red and green light. While both of these are technically correct ways to interpret the word “blue,” we’re pretty sure that neither of these definitions is how you thought about the word. When hearing the word “blue,” you may have thought of your favorite color, the color of the sky on a spring day, or the color of a really ugly car you saw in the parking lot. When people think about language, there are two different types of meanings that people must be aware of: denotative and connotative. (p. 407)

Denotative meaning is the specific meaning associated with a word. We sometimes refer to denotative meanings as dictionary definitions. The scientific definitions provided above for the word “blue” are examples of definitions that might be found in a dictionary. Connotative meaning is the idea suggested by or associated with a word at a cultural or personal level. In addition to the examples above, the word “blue” can evoke many other ideas:

State of depression (feeling blue)
Indication of winning (a blue ribbon)
Side during the Civil War (blues vs. grays)
Sudden event (out of the blue)
States that lean toward the Democratic Party in their voting
A slang expression for obscenity (blue comedy)

Given these differences, the language you select may have different interpretations and lead to different perspectives. As a speechwriter (and communicator), being aware of different interpretations can allow you select language that is the most effective for your speaking context and audience.

Using Language to Craft Your Argument

Have you ever called someone a “wordsmith?” If so, you’re likely complimenting their masterful application of language. Language is not just something we use; it is part of who we are and how we think. As such, language can assist in clarifying your content and creating an effective message.

Achieve Clarity

Clear language is powerful language. If you are not clear, specific, precise, detailed, and sensory with your language, you won’t have to worry about being emotional or persuasive, because you won’t be understood. The goal of clarity is to reduce abstraction; clarity will allow your audience to more effectively track your argument and insight, especially because they only have one chance to listen.

Concreteness aids clarity. We usually think of concreteness as the opposite of abstraction. Language that evokes many different visual images in the minds of your audience is abstract language. Unfortunately, when abstract language is used, the images evoked might not be the ones you really want to evoke. Instead, work to be concrete, detailed, and specific. “Pity,” for example, is a bit abstract. How might you describe pity by using more concrete words?

Clear descriptions or definitions can aid in concreteness and clarity.

To define means to set limits on something; defining a word is setting limits on what it means, how the audience should think about the word, and/or how you will use it. We know there are denotative and connotative definitions or meanings for words, which we usually think of as objective and subjective responses to words. You only need to define words that would be unfamiliar to the audience or words that you want to use in a specialized way.

Describing is also helpful in clarifying abstraction. The key to description is to think in terms of the five senses: sight (visual: how does the thing look in terms of color, size, shape); hearing (auditory: volume, musical qualities); taste (gustatory: sweet, bitter, salty, sour, gritty, smooth, chewy); smell (olfactory: sweet, rancid, fragrant, aromatic, musky); and feel (tactile: rough, silky, nubby, scratchy).

If you were, for example, talking about your dog, concrete and detailed language could assist in “bring your dog to life,” so to speak, in the moment.

Boring and abstract: My dog is pretty great. He is well behaved, cute, and is friendly to all of our neighbors. I get a lot of compliments about him, and I really enjoy hanging out with him outside in the summer.
Concrete and descriptive: Buckley, my golden-brown Sharpei mix, is a one-of-a-kind hound. Through positive treat reinforcement, he learned to sit, shake, and lay down within one month. He will also give kisses with his large and wrinkly snout. He greats passing neighbors with a smile and enjoys Midwest sunbathing on our back deck in the 70-degree heat.

Doesn’t the second description do Image 5.2 more justice ? Being concrete and descriptive paints a picture for the audience and can increase your warrant’s efficacy. Being descriptive, however, doesn’t mean adding more words. In fact, you should aim to “reduce language clutter.” Your descriptions should still be purposeful and important.

Be Effective

Language achieves effectiveness by communicating the right message to the audience. Clarity contributes to effectiveness, but effectiveness also includes using familiar and interesting language.

Familiar language is language that your audience is accustomed to hearing and experiencing. Different communities and audience use language differently. If you are part of an organization, team, or volunteer group, there may be language that is specific and commonly used in those circles. We call that language jargon, or specific, technical language that is used in a given community. If you were speaking to that community, drawing on those references would be appropriate because they would be familiar to that audience. For other audiences, drawing on jargon would be ineffective and either fail to communicate an idea to the audience or implicitly community that you haven’t translated your message well (reducing your ethos).

In addition to using familiar language, draw on language that’s accurate and interesting. This is difficult, we’ll admit it! But in a speech, your words are a key component of keeping the audience motivated to listen, so interesting language can peak and maintain audience interest.

Active language is interesting language. Active voice , when the subject in a sentence performs the action, can assist in having active and engaging word choices. An active sentence would read, “humans caused climate change” as opposed to a passive approach of, “climate change was caused by humans.” Place subjects at the forefront. A helpful resource on active voice can be found here.

You must, however, be reflexive in the language process.

Practicing Reflexivity

Language reflects our beliefs, attitudes, and values – words are the mechanism we use to communicate our ideas or insights. As we learned in Chapter 1, communication both creates and is created by culture. When we select language, we are also representing and creating ideas and cultures – language has a lot of power.

To that end, language should be a means of inclusion and identification, rather than exclusion.

You might be thinking, “Well I am always inclusive in my language,” or “I’d never intentionally use language that’s not inclusive.” We understand, but intention is less important than effect.

Consider the term “millennial”— a categorization that refers to a particular age group. It can be useful to categorize different generations, particularly from a historical and contemporary perspective. However, people often argue that “millennials are the laziest generation” or “millennials don’t know hard work!” In these examples, the intention may be descriptive, but they are selecting language that perpetuates unfair and biased assumptions about millions of people. The language is disempowering (and the evidence, when present, is weak).

Language assists us in categorizing or understanding different cultures, ideas, or people; we rely on language to sort information and differentiate ourselves. In turn, language influences our perceptions, even in unconscious and biased ways.

The key is to practice reflexivity about language choices. Language isn’t perfect, so thinking reflexively about language will take time and practice.

For example, if you were crafting a hypothetical example about an experience in health care, you might open with a hypothetical example: “Imagine sitting for hours in the waiting room with no relief. Fidgeting and in pain, you feel hopeless and forgotten within the system. Finally, you’re greeted by the doctor and he escorts you to a procedure room.” It’s a great story and there is vivid and clear language. But are there any changes that you’d make to the language used?

Remember that this is a hypothetical example. Using reflexive thinking, we might question the use of “he” to describe the doctor. Are there doctors that are a “he”? Certainly. Are all doctors a “he”? Certainly not. It’s important to question how “he” gets generalized to stand-in for doctors or how we may assume that all credible doctors are men.

Practicing reflexivity means questioning the assumptions present in our language choices (like police men rather than police officers). Continue to be conscious of what language you draw on to describe certain people, places, or ideas. If you aren’t sure what language choices are best to describe a group, ask; listen; and don’t assume.

In this chapter, we discussed crafting complete, well-reasoned arguments. Claim, evidence, and warrant are helpful structural components when crafting arguments. Use Chapter 4 to aid in research that will enable you to locate the best evidence for each claim within your speech.

Remember, too, that language plays a central role in telling a compelling story. Up next: organizing and outlining.

The Importance of a Thesis Statement

In the last installment , I discussed the “tell them” approach to public speaking. Today’s installment will explain why you should make sure that your writing and public speaking includes a thesis statement. A thesis statement focuses your talk, which results in greater understanding from the audience (and that translates into less stress for you).

In this post I will first define what a thesis statement is, the importance of having a thesis statement, and how to incorporate a thesis statement into your writing and public speaking.

What is a Thesis Statement:

Very simply, your thesis statement is the main argument of your paper or speech. It tells the reader what you are trying to convince them of or explain to them. The thesis statement of this post is that you should include a thesis statement in your writing and public speaking.

The importance of a thesis statement:

A thesis statement allows a reader or listener to quickly understand what it is they should be getting from you. Much like the “tell them” approach, a thesis statement is an organizational tool. It ensures that there is no doubt about the purpose of what you are trying to communicate. It provides the audience with a clear takeaway.

But a thesis statement is also a persuasive tool. Regardless of if they leave or stop reading early or get confused later on, they will know the takeaway you provided them. This is especially important in longer presentations where a listener may lose focus.

How to incorporate it:

You should clearly state your thesis statement early in your presentation or speech. In this post, I included my thesis statement in my third sentence. Throughout your paper or speech make sure that you are consistently referencing back to your blog post both explicitly and implicitly.

Conclusion:

In summary, this post has defined what a thesis statement is, why it is important, and how to incorporate it into your writing and public speaking. I hope you will start using thesis statements in all your public speaking and writing.

Module 5: Choosing and Researching a Topic

Finding the purpose and central idea of your speech, learning objectives.

Identify the specific purpose of a speech.
Explain how to formulate a central idea statement for a speech.

General Purpose

The general purpose of most speeches will fall into one of four categories: to inform , to persuade , to entertain , and to commemorate or celebrate . The first step of defining the purpose of your speech is to think about which category best describes your overall goal with the speech. What do you want your audience to think, feel, or do as a consequence of hearing you speak? Often, the general purpose of your speech will be defined by the speaking situation. If you’re asked to run a training session at work, your purpose isn’t to entertain but rather to inform. Likewise, if you are invited to introduce the winner of an award, you’re not trying to change the audience’s mind about something; you’re honoring the recipient of the award. In a public speaking class, your general purpose may be included in the assignment: for instance, “Give a persuasive speech about . . . .” When you’re assigned a speech project, you should always make sure you know whether the general purpose is included in the assignment or whether you need to decide on the general purpose yourself.

Specific Purpose

Now that you know your general purpose (to inform, to persuade, or to entertain), you can start to move in the direction of the specific purpose. A specific purpose statement builds on your general purpose and makes it more specific (as the name suggests). So if your first speech is an informative speech, your general purpose will be to inform your audience about a very specific realm of knowledge.

In writing your specific purpose statement, you will take three contributing elements and bring them together to help you determine your specific purpose :

You (your interests, your background, experience, education, etc.)
Your audience
The context or setting

A diagram with three words at the top: YOU, YOUR AUDIENCE, and YOUR CONTEXT, each with an arrow pointing to the next level, which is a box containing the words Specific Purpose Statement. This box points to the next box: Central Idea Statement

There are three elements that combine to create a specific purpose statements: your own interests and knowledge, the interests and needs of your audience, and the context or setting in which you will be speaking.

Keeping these three inputs in mind, you can begin to write a specific purpose statement, which will be the foundation for everything you say in the speech and a guide for what you do not say. This formula will help you in putting together your specific purpose statement:

To _______________ [ Specific Communication Word (inform, explain, demonstrate, describe, define, persuade, convince, prove, argue)] _______________ [ Target Audience (my classmates, the members of the Social Work Club, my coworkers] __________________. [ The Content (how to bake brownies, that Macs are better than PCs].

Example: The purpose of my presentation is to demonstrate to my coworkers the value of informed intercultural communication .

Formulating a Central Idea Statement

While you will not actually say your specific purpose statement during your speech, you will need to clearly state what your focus and main points are going to be. The statement that reveals your main points is commonly known as the central idea statement (or just the central idea). Just as you would create a thesis statement for an essay or research paper, the central idea statement helps focus your presentation by defining your topic, purpose, direction, angle, and/or point of view. Here are two examples:

Central Idea—When elderly persons lose their animal companions, they can experience serious psychological, emotional, and physical effects.
Central Idea—Your computer keyboard needs regular cleaning to function well, and you can achieve that in four easy steps.

Please note that your central idea will emerge and evolve as you research and write your speech, so be open to where your research takes you and anticipate that formulating your central idea will be an ongoing process.

Below are four guidelines for writing a strong central idea.

Your central idea should be one, full sentence.
Your central idea should be a statement, not a question.
Your central idea should be specific and use concrete language.
Each element of your central idea should be related to the others.

Using the topic “Benefits of Yoga for College Students’ Stress,” here are some correct and incorrect ways to write a central idea.

A strong central idea shows that your speech is focused around a clear and concise topic and that you have a strong sense of what you want your audience to know and understand as a result of your speech. Again, it is unlikely that you will have a final central idea before you begin your research. Instead, it will come together as you research your topic and develop your main points.

Chapter 3: Preparing for Your First Speech

Determining Your Thesis

Once you have determined your specific purpose (to convince your audience that smoking is harmful), you probably feel that you have narrowed your topic sufficiently to begin gathering information. You begin an online search using some of the key words from your specific purpose (for instance, the harmful effects of smoking) and you are amazed to find that those few key words yield hundreds of possible results -lung cancer, throat and tongue cancer, emphysema, hardening of the arteries, accelerated aging, pulmonary disease, and the list goes on and on. You know you can’t possibly discuss all of these effects in a four- to five-minute speech, so what now? Now you need to become selective. Which of those results most interests you? Which might best persuade your audience to quit smoking? You narrow your topic further and decide to concentrate solely on the research involving lung cancer. But which points about lung cancer do you want to share in your presentation? You need a thesis statement -one sentence that pulls all of your information together and informs your audience of the major points that you intend to cover during your speech. A thesis statement for a speech on lung cancer might choose to examine the link between lung cancer and smoking, the treatment options for lung cancer patients, and the mortality rate for this type of cancer.

A thesis statement provides your audience with a “preview ” of your speech in much the same way that a movie trailer previews an upcoming new movie. Movie trailers reveal enough about the movie to capture the audience’s attention and to gain their interest; an effective movie trailer shows us just enough to make us want to see the movie. You want your thesis to do the same. An effective thesis lets your audience know what ideas you’ll cover, what you consider most important, and how many details you’ll include. The movie trailer certainly doesn’t reveal the ending or show you the entire movie. Your thesis, likewise, doesn’t go into great detail. You don’t give all your facts, tell all your stories, or share all of your examples in your introduction; you share that information gradually as you work your way through the speech. Your thesis, then, is simply an overview -or a preview -of what your audience will hear if they continue to pay attention and listen to all of your presentation.

Selecting a Topic

Generally, speakers focus on one or more interrelated topics—relatively broad concepts, ideas, or problems that are relevant for particular audiences. The most common way that speakers discover topics is by simply observing what is happening around them—at their school, in their local government, or around the world. Student government leaders, for example, speak or write to other students when their campus is facing tuition or fee increases, or when students have achieved something spectacular, like lobbying campus administrators for lower student fees and succeeding. In either case, it is the situation that makes their speeches appropriate and useful for their audience of students and university employees. More importantly, they speak when there is an opportunity to change a university policy or to alter the way students think or behave in relation to a particular event on campus.

But you need not run for president or student government in order to give a meaningful speech. On the contrary, opportunities abound for those interested in engaging speech as a tool for change. Perhaps the simplest way to find a topic is to ask yourself a few questions. See the textbox entitled “Questions for Selecting a Topic” for a few questions that will help you choose a topic.

Questions for Selecting a Topic

What important events are occurring locally, nationally and internationally?
What do I care about most?
Is there someone or something I can advocate for?
What makes me angry/happy?
What beliefs/attitudes do I want to share?
Is there some information the audience needs to know?

Once you have answered these questions and narrowed your responses, you are still not done selecting your topic. For instance, you might have decided that you really care about breeds of dogs. This is a very broad topic and could easily lead to a dozen different speeches. To resolve this problem, speakers must also consider the audience to whom they will speak, the scope of their presentation, and the outcome they wish to achieve.

Formulating the Purpose Statements

By honing in on a very specific topic, you begin the work of formulating your purpose statement. In short, a purpose statement clearly states what it is you would like to achieve. Purpose statements are especially helpful for guiding you as you prepare your speech. When deciding which main points, facts, and examples to include, you should simply ask yourself whether they are relevant not only to the topic you have selected, but also whether they support the goal you outlined in your purpose statement. The general purpose statement of a speech may be to inform, to persuade, to celebrate, or to entertain. Thus, it is common to frame a specific purpose statement around one of these goals. According to O’Hair, Stewart, and Rubenstein, a specific purpose statement “expresses both the topic and the general speech purpose in action form and in terms of the specific objectives you hope to achieve (2004). For instance, the home design enthusiast might write the following specific purpose statement: At the end of my speech, the audience will learn the pro’s and con’s of flipping houses . In short, the general purpose statement lays out the broader goal of the speech while the specific purpose statement describes precisely what the speech is intended to do. Some of your professors may ask that you include the general purpose and add the specific purpose.

Writing the Thesis Statement

The specific purpose statement is a tool that you will use as you write your talk, but it is unlikely that it will appear verbatim in your speech. Instead, you will want to convert the specific purpose statement into a central idea, or thesis statement that you will share with your audience.

Depending on your instructor’s approach, a thesis statement may be written two different ways. A thesis statement may encapsulate the main points of a speech in just a sentence or two, and be designed to give audiences a quick preview of what the entire speech will be about. The thesis statement for a speech, like the thesis of a research-based essay, should be easily identifiable and ought to very succinctly sum up the main points you will present. Some instructors prefer that your thesis, or central idea, be a single, declarative statement providing the audience with an overall statement that provides the essence of the speech, followed by a separate preview statement.

If you are a Harry Potter enthusiast, you may write a thesis statement (central idea) the following way using the above approach: J.K. Rowling is a renowned author of the Harry Potter series with a Cinderella like story having gone from relatively humble beginnings, through personal struggles, and finally success and fame .

Writing the Preview Statement

However, some instructors prefer that you separate your thesis from your preview statement. A preview statement (or series of statements) is a guide to your speech. This is the part of the speech that literally tells the audience exactly what main points you will cover. If you were to open your Waze app, it would tell you exactly how to get there. Best of all, you would know what to look for! So, if we take our J.K Rowling example, let’s rewrite that using this approach separating out the thesis and preview:

J.K. Rowling is a renowned author of the Harry Potter series with a Cinderella like rags to riches story. First, I will tell you about J.K. Rowling’s humble beginnings. Then, I will describe her personal struggles as a single mom. Finally, I will explain how she overcame adversity and became one of the richest women in the United Kingdom.

There is no best way to approach this. This is up to your instructor.

Writing the Body of Your Speech

Once you have finished the important work of deciding what your speech will be about, as well as formulating the purpose statement and crafting the thesis, you should turn your attention to writing the body of your speech. All of your main points are contained in the body, and normally this section is prepared well before you ever write the introduction or conclusion. The body of your speech will consume the largest amount of time to present; and it is the opportunity for you to elaborate on facts, evidence, examples, and opinions that support your thesis statement and do the work you have outlined in the specific purpose statement. Combining these various elements into a cohesive and compelling speech, however, is not without its difficulties, the first of which is deciding which elements to include and how they ought to be organized to best suit your purpose.

Good design is making something intelligible and memorable. Great design is making something memorable and meaningful.

13 Specific Purpose

Learning Objectives

Create a specific purpose to determine speech goals.

What Is Your Purpose?

There are two purposes for public speaking: general and specific. Purpose statements are especially helpful for guiding you as you prepare your speech. The general purpose refers to the broad goal for creating and delivering the speech. The specific purpose, on the other hand, starts with one of those broad goals and then further informs the listener about the who , what , when , where , why , and how of the speech. The specific purpose answers the question: What do you want to accomplish by the end of your speech?

The specific purpose is the combination of factors that make speeches and other discourse meaningful and a useful way to change the way something is. It is stated as a sentence incorporating the general purpose, the specific audience for the speech, and a prepositional phrase that summarizes the topic. Suppose you are going to give a speech about using open-source software. Here are two examples, each with a similar topic but a different general purpose and a different audience:

In each of these examples, you will notice that there is a general purpose (to inform or to persuade); the specific purpose follows the goal of the speech and allows the speaker to fine-tune their purpose by being more specific. Before you can think strategically about your speech content, you need to know what your specific purpose is. Once you have decided on the topic, intention, and general purpose of your speech, you can begin to write your specific purpose statement. You will not state this purpose verbatim in your speech but you will use it to craft a thesis statement that you will state verbatim in your speech.

Write your general and specific purpose for your informative speech now.

Key Takeaways

Specific purposes are important to the speech making process.

Your specific purpose will support your speech by informing the listener about your speech and the goals of your speech.
You may not specifically state the specific purpose but it will guide your intention of the speech.
The specific purpose will help guide your speech. You can always refer back to the specific purpose if you begin to “get in the weeds” with your information, research, and support.
Ask yourself: What do you want to accomplish by the end of your speech?

16 Formulating a Central Idea Statement

While you will not actually say your specific purpose statement during your speech, you will need to clearly state what your focus and main points are going to be (preferably after using an introductory method such as those described in Chapter 8). The statement that reveals your main points is commonly known as the central idea statement (or just the central idea).

Now, at this point we need to make a point about terminology. Your instructor may call the central idea statement “the thesis” or “the thesis statement.” Your English composition instructor probably uses that term in your essay writing. Another instructor may call it the “main idea statement.” All of these are basically synonymous and you should not let the terms confuse you, but you should use the term your instructor uses.

That said, is the central idea statement the very same thing as the thesis sentence in an essay? Yes, in that both are letting the audience know with- out a doubt your topic, purpose, direction, angle and/or point of view. No, in that the rules for writing a “thesis” or central idea statement in a speech are not as strict as in an essay. For example, it is acceptable in a speech to announce the topic and purpose, although it is usually not the most artful or effective way to do it. You may say,

“In this speech I will try to motivate you to join me next month as a volunteer at the regional Special Olympics.”

That would be followed by a preview statement of what the speech’s arguments or reasons for participating will be, such as,

“You will see that it will benefit the community, the participants, and you individually.”

However, another approach is to “capsulize” the purpose, topic, approach, and preview in one succinct statement.

“Your involvement as a volunteer in next month’s regional Special Olympics will be a rewarding experience that will benefit the community, the participants, and you personally.”

This last version is really the better approach and most likely the one your instructor will prefer.

So, you don’t want to just repeat your specific purpose in the central idea statement, but you do want to provide complete information. Also, unlike the formal thesis of your English essays, the central idea statement in a speech can and should use personal language (I, me, we, us, you, your, etc.) and should attempt to be attention-getting and audience-focused.

And importantly, just like a formal thesis sentence, it must be a complete, grammatical sentence.

The point of your central idea statement in terms of your audience is to reveal and clarify the ideas or assertions you will be addressing in your speech, more commonly known as your main points, to fulfill your specific purpose. However, as you are processing your ideas and approach, you may still be working on them. Sometimes those main points will not be clear to you immediately. As much as we would like these writing processes to be straightforward, sometimes we find that we have to revise our original approach. This is why preparing a speech the night before you are giving it is a really, really bad idea. You need lots of time for the preparation and then the practice.

Sometimes you will hear the writing process referred to as “iterative.” This word means, among other things, that a speech or document is not always written in the same order as the audience finally experiences it. You may have noticed that we have not said anything about the introduction of your speech yet. Even though that is the first thing the audience hears, it may be one of the last parts you actually compose. It is best to consider your speech flexible as you work on it, and to be willing to edit and revise. If your instructor asks you to turn the outline in before the speech, you should be clear on how much you can revise after that. Otherwise, it helps to know that you can keep editing your speech until you deliver it, especially while you practice.

Here are some examples of pairs of specific purpose statements and central idea statements.

Specific Purpose: To explain to my classmates the effects of losing a pet on the elderly.

Central Idea: When elderly persons lose their animal companions, they can experience serious psychological, emotional, and physical effects.

Specific Purpose: To demonstrate to my audience the correct method for cleaning a computer keyboard.

Central Idea: Your computer keyboard needs regular cleaning to function well, and you can achieve that in four easy steps.

Specific Purpose: To persuade my political science class that labor unions are no longer a vital political force in the U.S.

Central Idea: Although for decades in the twentieth century labor unions influenced local and national elections, in this speech I will point to how their influence has declined in the last thirty years.

Specific Purpose: To motivate my audience to oppose the policy of drug testing welfare recipients.

Central Idea: Many voices are calling for welfare recipients to go through mandatory, regular drug testing, but this policy is unjust, impractical, and costly, and fair-minded Americans should actively oppose it.

Specific Purpose: To explain to my fellow civic club members why I admire Representative John Lewis.

Central Idea: John Lewis has my admiration for his sacrifices during the Civil Rights movement and his service to Georgia as a leader and U.S. Representative.

Specific Purpose: To describe how makeup is done for the TV show The Walking Dead.

Central Idea: The wildly popular zombie show The Walking Dead achieves incredibly scary and believable makeup effects, and in the next few minutes I will tell you who does it, what they use, and how they do it.

Notice that in all of the above examples that neither the specific purpose nor the central idea ever exceeds one sentence. You may divide your central idea and the preview of main points into two sentences or three sentences, depending on what your instructor directs. If your central idea consists of more than three sentences, then you probably are including too much information and taking up time that is needed for the body of the speech. Additionally, you will have a speech trying to do too much and that goes overtime.

Donald Trump’s Attorney Fumes At Michael Cohen In Effort To Discredit Testimony Of Prosecution’s Star Witness: “That Was A Lie”

By Sean Piccoli

Sean Piccoli

ABC News' David Muir And Linsey Davis To Moderate September Presidential Debate

CNN's Jake Tapper And Dana Bash Will Moderate June Presidential Debate

The moment was a highlight of today’s proceedings in the hush money trial of the former president.

Cohen was Trump’s former attorney and so-called fixer. He testified on Tuesday that he reached Trump by calling the bodyguard, Keith Schiller, that day, October 24, 2016, and that he spoke to Trump on Schiller’s phone to let him know that a deal with Daniels was close. Cohen said this afternoon that his recollection was based on his review of phone records provided by prosecutors. But he admitted that he didn’t remember the problem with the prankster until seeing the texts with Schiller today.

“I believe I also told Trump — ” Cohen began, referring to the 90-second call over Schiller’s phone.

“We are not asking your for belief,” Blanche snapped, cutting him off. “This jury doesn’t want to hear what you think happened.”

The comment drew an objection from Assistant Manhattan District Attorney Susan Hoffinger. The trial paused for lunch shortly after that exchange.

On his second day of cross-examination, Cohen faced more skeptical questions from Blanche about his character, motives, past lying under oath, and penchant for sounding off about the man he used to affectionately call “Boss” before legal troubles partly tied to the $130,000 payment landed him behind bars.

Blanche had jurors listen to Cohen saying “revenge is a dish best served cold” last October in a podcast. Cohen said in the same podcast that he wanted Trump to go to prison, just as he had.

Blanche, plowing through multiple prosecution objections, took repeated aim at Cohen’s testimony this week in an apparent effort to damage his credibility with jurors — as when Cohen testified on Tuesday that he never wanted to work in the Trump White House. Blanche confronted Cohen with conversations and correspondence that showed his interest in becoming Trump’s chief of staff or attorney general.

Cohen today repeated that he just wanted to be asked about those roles. “That was for my ego,” Cohen said.

Cohen did admit to lying under oath on previous occasions: He said he lied in 2018 to the federal judge accepting his guilty plea on tax and banking charges.

Cohen said that he should not have faced criminal charges as a first-time tax offender but felt pressured by federal investigators who were threatening to also charge his wife — information Cohen admitted he didn’t share with the judge.

“I believe you still feel you did not engage in tax fraud, but you felt you had to protect your wife and family,” Blanche said. “Correct,” Cohen replied.

Cohen said he still thinks that judge — William H. Pauley III, who died in 2021 — colluded with federal prosecutors from New York who were targeting him on orders from the Trump White House. That’s largely the thesis of Cohen’s book, Revenge .

Blanche said that Cohen, far from “accepting responsibility” for his crimes — as he has said under oath that he did — had at different points blamed his accountant, banker, federal law enforcement officials or the Trump White House for his legal woes.

“I don’t dispute the facts of the case but I should not have been prosecuted,” Cohen testified today.

Cohen pleaded guilty to lying to Congress in 2017 about Trump’s business activities in Moscow. Today, Blanche reminded Cohen of problems with a written statement that Cohen delivered under oath to Congress two years later. Cohen declared in that 2019 appearance on Capitol Hill that he would never ask for, or accept, a pardon from then-President Trump.

In truth, Cohen had previously directed his lawyers to explore the possibility of a pardon. Cohen said today that his congressional statement was true when he made it, but acknowledged that his lawyers went back to Congress to correct the record.

The prosecution’s case against Donald Trump is winding down in court, but the background noise around the proceedings may be getting louder. This morning, on his way into the courtroom, Trump singled out Assistant District Attorney Matthew Colangelo, a former U.S. Department of Justice official before joining the local DA’s office and its Trump prosecution team.

Trump baselessly called Colangelo’s involvement proof that President Biden “is running this trial.”

Trump is still contesting the gag order imposed by Judge Juan Merchan: He’s appealed to New York state’s highest court to remove a restriction that has already seen him fined $10,000 and threatened with jail for public statements about jurors, witnesses and other trial participants or their families.

This morning’s entourage included Lauren Boebert and Matt Gaetz, Republican House members known for bashing the former president’s critics and regularly making news themselves for their own behavior. Boebert and Gaetz took seats directly behind Trump in the gallery next to Trump’s oldest son, Eric Trump.

One question this week is whether Trump is using surrogates to get around Judge Merchan’s gag order, and whether the Manhattan District Attorney’s office will make an issue of it. A reporter covering the trial for New York magazine told MSNBC on Tuesday evening that he saw Trump in court that day marking up a document with talking points used by his allies outside the courthouse.

Merchan’s gag order forbids Trump from criticizing trial participants, or directing others to do so, but it’s not clear if prosecutors will again ask the judge to intervene and sanction the defendant.

Johnson on Tuesday was openly critical of Merchan’s daughter, a Democratic campaign worker who is protected under the gag order but remains the unnamed source of Trump’s ongoing complaints about a “conflicted” trial judge. Sen. Tommy Tuberville, Republican of Alabama, told reporters he was “disappointed in looking at the American — supposedly American — citizens in that courtroom,” a remark widely interpreted as a dig at the jury.

Tuberville later clarified that he meant other people, not jurors, “trying to transition this country into something that it’s not.” He also said he hopes to “overcome this gag order.”

On Tuesday morning, as Trump entered court, a hallway pool reporter asked if he was directing surrogates to speak on his behalf. “I do have a lot of surrogates and they are speaking very beautifully,” Trump replied.

Cohen, the former Trump lawyer and self-styled “fixer,” spent Tuesday afternoon on the stand quietly parrying questions from Blanche about his credibility. So far the particulars of the DA’s case against Trump haven’t come up in cross examination.

The core allegation is that Trump sought to illegally influence the 2016 election using falsified invoices, checks and pay stubs to disguise the repayment to Cohen as ongoing legal work. Trump denies Daniels’ claim that they had sex in 2006 at a celebrity golf tournament in Lake Tahoe, when he was married and had a newborn son.

Trump’s lawyers defend the non-disclosure agreement with Daniels as routine business and a legal exercise of his right as a candidate to head off bad news in the heat of a political campaign.

Cohen is reportedly the prosecution’s last witness before the defense gets its turn to put on a case in a trial that has gone by more quickly than many observers expected. In a sidebar conference with the judge on Tuesday, out of earshot of jurors, Blanche said he still didn’t know whether his client will decide to testify.

The trial has gotten quieter by one measure: Since testimony began, public protests outside the courthouse have been low-key to nonexistent. This morning Trump blamed the heavy security. “Outside, if you take a look, it looks like Fort Knox. So many police and they don’t allow people to come. You’re not allowed to have friendly protests, we’re not allowed to have anything here.”
