In what scenario would a speaker most commonly use a visual aid?

Using a visual aid to support a speaker's verbal message is a fundamental practice in public speaking. Visual aids, such as slides, charts, graphs, or images, serve to enhance understanding, retention, and engagement among the audience. They can clarify complex information, provide illustrations of key points, and help to reinforce the speaker's argument or narrative.

When a visual aid is used effectively, it complements what is being said and allows the audience to visualize the concepts being discussed. This is particularly beneficial in presentations that involve data or statistics, as visual representations can make those elements more accessible and impactful. By using visual aids in this manner, speakers can communicate their ideas more effectively and ensure the audience grasps the intended message.
