Media Captions

Do media have captions for audio and descriptions for information provided visually?

People who are deaf or hard of hearing have limited or no access to the audio track of video content on a web page.

Captions provide a synchronized text equivalent to spoken and key non-spoken content for video. They are superimposed on the video so a viewer can see the video and read the captions at the same time as the words are spoken or the sound is made. When they are available as closed captions, the display of captions can be turned on or off using a control on the video player's. Videos with open captions have the caption text burned into the video, so the captions are permanently available to everyone.

When captions are not provided, people who can't hear the soundtrack will be unable to understand the content of the video.
