When you use videos, be sure it has synchronized captions. If you include a video that already has captions, then you do not have to worry about this step. Something else that should be kept in mind is that any video/audio files should have a text transcript. If you insert the content as an object, you need to provide an alt text for it.
Section 7.1: Captions for Presentations:
Many people listening to your presentation may not be able to hear you speak. To fix this issue, provide live captions for your audience. To make captions visible,
Click the Slideshow button.
In presentation mode, click the Options Menu in the bottom left corner. It has three vertical dots.
Click Captions Preferences, then Toggle Captions. You can change the position and text size of the font. It is always good to have the font be at the bottom of the screen and a large size.
