Final answer:
A speaker should not necessarily reschedule their presentation if presentational aids fail; instead, they should be prepared to proceed without them, focusing on delivering the content of their talk effectively and considering the accessibility needs of the audience.
Step-by-step explanation:
The question is whether a speaker should reschedule their presentation if their presentational aid, such as PowerPoint, does not work. The answer is false. It is preferable for a speaker to have their presentation aids working, as they can enhance the effectiveness of the speech. However, if a presentational aid fails, a speaker should be prepared to proceed without it, possibly by using an alternative method such as an infographic or an adapted delivery script that accounts for accessibility. It is important for a speaker to plan ahead for potential technical difficulties and to ensure that the content of their talk can stand on its own.
Speakers can strengthen their message by considering the accessibility needs of their audience, such as those with visual or auditory impairments. A consistent visual style, spacing, and timing for media elements are also critical to avoid detracting from the main message of the presentation. Ultimately, while presentational aids are helpful, they are not absolutely necessary for delivering a successful speech.
