Success criterion
Conformance level
Essential baseline — must meet for any compliance.
What it means
This covers two distinct cases. First, audio-only content: a podcast, a recorded phone call, or any standalone audio file. Second, video-only content: a silent animation, a screen recording with no narration, or any video with no meaningful audio track.
For audio-only content, a full written transcript makes the content accessible to people who are Deaf or hard of hearing. The transcript needs to include all spoken words plus any meaningful sounds such as applause or a door closing if those sounds carry information.
For video-only content, you can either provide a written description of what happens visually, or record a separate audio track narrating the visual content.
In practice
For a podcast or audio recording, publish a complete transcript on the same page or linked directly from the audio player. Include speaker names where there are multiple voices.
For a silent product demo or animation, write a step-by-step description of every action shown, or record a voiceover narrating what the viewer is watching.
Transcripts must cover all meaningful content. A summary or set of bullet points is not sufficient.
Common failures
- Podcast published with no transcript and no link to one
- Silent how-to video with no written description of the steps shown
- Transcript that summarises content rather than representing it fully
