Rhetorical questions are questions asked to make a point rather than to elicit an answer, as the answer is obvious or implied. They can be used in speeches to engage audiences, emphasize points, and persuade listeners. Some effective techniques for using rhetorical questions include asking questions that personalize the topic to listeners, evoke emotions, emphasize statements, predict audience questions, and use consecutive questions to highlight conflicting or supporting viewpoints. Rhetorical questions should be phrased so that listeners can easily supply the intended answer without it needing to be stated explicitly.
