Finally, speakers should consider time limits when choosing an informative speech topic. A topic should be covered thoroughly enough that the audience feels as if most of their questions on the topic have been answered. On the other hand, a tight time restriction may prevent the speaker from adequately covering a very intricate topic. When time is limited, a subject which requires lengthy explanation should be avoided. The audience should leave an informative speech feeling as if they’ve gained new insight on a topic. It is good if they are interested in doing their own research to learn more about the subject, but they should never leave the presentation feeling confused or unclear about what they have just heard.
