What is the purpose of a rhetorical question in a speech?

The purpose of a rhetorical question in a speech is primarily to make the audience think silently. Rhetorical questions are designed to provoke thought and reflection rather than to elicit a direct response. They engage the audience by prompting them to consider the implications or answers within the context of the speaker’s message. This technique can create a more interactive atmosphere, as the audience finds themselves mentally engaged with the ideas being presented.

In this context, while rhetorical questions may unintentionally lead to discussions or encourage dialogue, their main function is not that. Instead, they serve to enhance the speech by inviting listeners to ponder and resonate with the concepts discussed. This mental engagement is crucial for effective communication and helps to reinforce the speaker's points without requiring immediate feedback.
