Provide an alternative to video-only and audio-only content
Users who have difficulty with hearing and/or vision may need assistance with audio-only or video only content, such as an audio file, embedded podcast or silent film.
By providing the same information in a different format, these users can access the content by other means, such as text or assistive technology.
How to pass
- Provide a text transcript that conveys the same information as audio-only media;
- Provide a text transcript that conveys the same information as video-only media; or
- Provide an audio-track that conveys the same information as video-only media.
You don’t need to provide an alternative if the content is itself an alternative for text.
Sometimes creating a text transcript is simple, other times you have to make a judgement call on what to include. The best bet is, as always, to be honest with your users. What does the media convey and does your transcript do the same? Could you swap one for the other?
A text transcript for a video without sound should describe what is going on in the video as clearly as possible. Try to focus on what the video is trying to say rather than getting bogged down with detail.
Alternatively for video-only content, record an audio track that narrates the video.
For both audio-only and video-only, create your text transcript and place it either directly beneath the content or insert a link next to the content.
