Website Accessibility Tip of the Week: Provide Transcripts
Pre-Recorded Audio Files & Video-Only Files Best Practices
Immediately following an audio file or video-only hyperlink, include a secondary link to the corresponding transcript (if linking to a transcript document, ensure that the document itself meets the document accessibility requirements).
Transcripts must be a verbatim record of everything that speaker(s) say(s). It identifies who is speaking as well as noting other significant sounds that are part of the recording, such as applause, laughter, questions from the audience, and so on.
Always create and include a transcript with a silent movie and consider creating an audio track that includes a description of the action in the video. This makes it possible for users with and without vision impairment to review content simultaneously.
A text equivalent is not required for audio that is provided as an equivalent for video with no audio information. For example, it is not required to caption video description that is provided as an alternative to a silent movie.
See the additional resources below to learn more details about the WCAG 2.0 Guideline 1.2 and Success Criterion 1.2.1:
The audio control accessibility guideline is based on the first Web Content Accessible Guide (WCAG) 2.0 principle, Level A: Principle 1 – Perceivable and states: Information and user interface components must be presentable to users in ways they can perceive.
The WCAG 2.0 Guideline 1.2 - Time-Based Media was created based on that principle stating: Provide alternatives for time-based media.
The WCAG 2.0 Success Criterion 1.2.1 - Audio-only and Video-only (Prerecorded) states: For prerecorded audio-only and prerecorded video-only media, the following are true, except when the audio or video is a media alternative for text and is clearly labeled as such:
- Prerecorded Audio-only: An alternative for time-based media is provided that presents equivalent information for prerecorded audio-only content.
- Prerecorded Video-only: Either an alternative for time-based media or an audio track is provided that presents equivalent information for prerecorded video-only content.
