Visual aids help a speaker reinforce speech content visually, which helps amplify the speaker’s message. They can be used to present any of the types of supporting materials discussed previously. Speakers rely heavily on an audience’s ability to learn by listening, which may not always be successful if audience members are visual or experiential learners. Even if audience members are good listeners, information overload or external or internal noise can be barriers to a speaker achieving his or her speech goals. Therefore skillfully incorporating visual aids into a speech has many potential benefits:
Helping your audience remember information because it is presented orally and visually
Helping your audience understand information because it is made more digestible through diagrams, charts, and so on
Helping your audience see something in action by demonstrating with an object, showing a video, and so on
Engaging your audience by making your delivery more dynamic through demonstration, gesturing, and so on
