What term is used for reminding an audience about the thesis during the conclusion of a speech?

The term that best describes reminding an audience about the thesis during the conclusion of a speech is "instant-replay function." This term emphasizes the practice of revisiting the main points or thesis to reinforce the message and ensure that the audience retains the key ideas presented throughout the speech. By revisiting the thesis in the conclusion, the speaker helps solidify the main argument and enhances audience retention, leaving a lasting impression.

The other terms mentioned have different meanings and are not specifically related to reiterating the thesis. For instance, forecasting pertains to outlining what is to come later in a speech, and the appeal to action typically encourages the audience to take specific steps or actions following the speech. The forewarning function involves cautioning the audience about potential issues or misunderstandings, which does not focus on summarizing the thesis. Thus, the "instant-replay function" effectively encapsulates the practice of reiterating the thesis for clarity and impact in the concluding segment of a speech.
