What factor should a speaker consider to ensure their topic is relevant and engaging for the audience?

Considering the audience's existing knowledge about the subject is crucial for ensuring that a topic remains relevant and engaging. When a speaker understands what the audience already knows, they can tailor their message to either build upon that knowledge or introduce new concepts in a way that resonates with their understanding. This enhances the connection between the speaker and the audience, making the content more relatable and easier to absorb. If the topic is too advanced or too simplistic compared to the audience's background, it may result in disengagement.

Knowledge of the audience serves as a foundation for crafting a message that captures attention and sustains interest throughout the presentation. By assessing the listeners' familiarity with the topic, the speaker can adjust their approach to maintain a dynamic and interactive environment, ensuring that the content is both relevant and stimulating.
