Why should an introduction to a speech offer the central idea and preview the main points to be discussed?

The general purpose of any speech will be either to Inform; Motivate/Persuade; or Entertain your audience. As soon as you know the general purpose of your speech you can develop your Specific Purpose Statement (What the speaker will accomplish). Your Specific Purpose Statement is used to develop your speech. You don't acutally say it in your speech.

Restrict your Specific Purpose to one idea only. In Speech 151 for the informative speech your general purpose is to inform. For an informative speech you will want to start your specific purpose statement with "I will inform my audience about...." A Specific Purpose Statement for an informative speech will be phrased much like the following statements. Click here for more examples of Specific Purposes, Central Ideas, and Main Points.

Informative speech specific purpose statements:

• I will inform my audience about the two major forms of hula.
• I will inform my audience about what lifegaurds do as part of their jobs.

When you have your specific purpose statement you are ready to compose your Thesis Statement/Central Idea (they are one in the same). This is the most important part of your speech. This is one sentence that encompasses the central idea of your speech.

Writing your thesis statement/central idea is a four step process:

1. Choose your topic
2. Determine your general purpose
3. Write your specific purpose statement
4. Tie it all together by composing a clear concise thesis statement/central idea

"The two major forms of hula that have played an important role in Hawaiian history and have developed into unique dances are the Kahiko and 'Auana."

"Lifegaurding is a great way to spend your days on the beach, but the work includes training, teaching, and lots of practice making it more challenging than what you see on "Baywatch."

Your next step is to compose the main points of your speech. Main points are complete sentences that create a dialogue with your audience. With your main points you want to create questions in the mind of your audience. You will answer the question in your support of your main points. You make a claim in your main points and you support your claim in your subpoints, sub-subpoints, sub-sub-subpoints and so on.

The following are examples of Main points:

Specific Purpose: I will inform my audience about the two major forms of hula.

Central Idea: "The two major forms of hula that have played an important role in Hawaiian history and have developed into unique dances are the Kahiko and 'Auana."

1. (Main Point 1) "The ancient hula or Kahiko is a unique form of hula."
2. (Main Point 2) "The Kahiko plays an improtant role in the history of Hawaii."
3. (Main Point 3) "The 'Auana or modern hula has played an important role in Hawaiian history."
4. (Main Point 4) "The 'Auana has developed into a unique form of dance and storytelling."

The introduction and conclusion of a speech are essential. The audience will remember the main ideas even if the middle of the speech is a mess or nerves overtake the speaker.  So if nothing else, get these parts down!

Introduction

The introduction gives the audience a reason to listen to the remainder of the speech. A good introduction needs to get the audience’s attention, state the topic, make the topic relatable, establish credibility, and preview the main points. Introductions should be the last part of the speech written, as they set expectations and need to match the content.

Attention getters

The first few sentences of a speech are designed to catch and maintain the audience’s attention. Attention getters give the audience a reason to listen to the rest of the speech. Your attention getter helps the audience understand and reflect on your topic.

• Startle the audience
  • Speaker walks up to stage with notes stuck to hands with jelly.
• Rhetorical question
  • Did you know there is a right way to make a peanut butter and jelly sandwich?
• Quote
  • Rob Gronkowski once said, “Usually, about 2 hours before a game, I stuff in a nice peanut butter and jelly [sandwich] with chocolate milk.”
• Story
  • A little boy walks in from a long day at school, telling his mom that he is starving. His mom is confused because she knows she sent him to school with a full lunch. As she opens his lunch box, she sees his peanut butter and jelly, with the grape jelly smeared on the side of the bag. She realizes there has to be a better way to make a PB&J.
• Imagery, song, visual…
  • Bring in a clear sandwich bag with jelly seeping through the bread of a peanut butter and jelly sandwich.

Logical orientation

Once the audience is invested in the speech, logical orientation tells the audience how the speaker will approach and develop the topic.

• Your thesis needs to be stated clearly and concisely
  • Peanut butter on both sides of the bread with jelly in the middle is the best way to make a PB&J.
• Provide background information so the audience is able to follow your topic
  • PB&Js have developed a bad reputation, because of the jelly making the bread soggy and hands sticky.

Psychological orientation

Like the logical orientation of a speech, the psychological orientation is also going to provide the audience with a map for how and why the topic is being presented.

• Make the topic relatable for the audience
  • Most of us remember our moms – dads too – packing a peanut butter and jelly sandwich in our lunches. We also remember how the jelly did not just stay in the sandwich, but became a new stain on our shirts and the glue that held all the playground dirt to our hands.
• Motivate the audience to see the importance of the topic
  • We can end this torture for future generations by making sure all parents are aware of the best way to make a PB&J.
• Establish your credibility as speaker on the topic
  • I have eaten numerous PB&Js myself, but my real authority on the topic comes from being a mom of two boys and the maker of many PB&Js.

Both the logical and psychological orientations give the audience a road map for the speech ahead as well as cues for what to listen to. This will help the audience transition from the introduction to the main points of the speech.
