One of the most important functions of the conclusion is to prepare the audience for the end of the speech.

Throughout the speech, you have been providing the audience with verbal and nonverbal cues to where you are going in the speech. As you move to the conclusion, you need to continue to provide these cues. You can use language cues (“now that we have seen that we can solve this problem effectively, we can review the entire situation”), movement cues (physically moving back to the center of the room where you began the speech), and paralinguistic cues (slow the rate of the speech, use more pauses) to help prepare your audience for the end of the speech.

When you prepare the audience for the end of the speech, you let them know that they need to be ready for any final comments or appeals from you, and that they should be prepared to acknowledge you as a speaker.
