Success Criterion 1.2.3 - Level A
Audio Description or Media Alternative (Prerecorded)
Ensure a transcript or audio description is provided for videos where you can't hear what is displayed. The content can then be read in case of a transcript, or heard in case of audio description.
Impact
A transcript is useful for anyone who has trouble understanding video frames.
People who are blind can hear what can be seen in videos through an additional audio track.
Check
“Is a transcript or audio description available for all videos?”
This can be tested visually, no assistive technologies are needed.
