What is one purpose of a speech introduction?

One purpose of a speech introduction is to establish credibility. This is essential because it helps the audience feel confident in the speaker's authority and knowledge on the subject matter. When a speaker effectively conveys their qualifications, experience, and relevant background in the introduction, it fosters trust and allows the audience to be more receptive to the information being presented. Establishing credibility sets a positive tone for the rest of the speech and helps to engage the audience from the outset.

In contrast, presenting counterarguments is typically a strategy used in the body of a speech, where the speaker addresses opposing views before rebutting them. Summarizing main points is also part of the body of the speech, where the speaker clarifies and reinforces key ideas after they've been presented. Concluding the speech is specifically reserved for wrapping up the discussion and imparting any final thoughts, which occurs at the end of the presentation. Each of these functions plays a role, but establishing credibility is fundamental right from the introduction, laying the groundwork for an impactful speech.
