Have your Mac speak audio descriptions for videos
Audio descriptions provide an audible narration of important onscreen action and content in movies and TV shows. If you have a video that includes audio descriptions, your Mac can read them aloud for you.
Choose Apple menu > System Preferences, click Accessibility, then click Descriptions.
Select the “Play audio descriptions when available” checkbox.
To turn the descriptions off, deselect the checkbox.
