- Success Criterion 1.2.1
- Conformance level A
Video Alternative Not Labeled as a Substitute for Article Text
1.2.1 — Audio-only and Video-only (Prerecorded)
Scenario
Setting
A crowdfunding platform's campaign page
What’s wrong
Media alternative for text not labeled as such, when relying on that exception.
Example
<audio src="podcast.mp3"></audio> Why it matters
Deaf people who need transcripts of audio-only media, and blind people who need alternatives to silent video.
How to test
Find any media marked as an alternative to on-page text: confirm it is explicitly labeled as such (e.g., 'audio version of this article') — unlabeled fails.
How to fix
A complete, accurate transcript (or an equivalent audio track for video-only media) must be provided and linked right next to the media.
<audio src="podcast.mp3"></audio><a href="podcast-transcript.html">Read the transcript</a>A text transcript gives Deaf users the same content the audio carries, with no video/audio dependency.
Outcome
On a crowdfunding platform's campaign page, this barrier is gone for deaf people who need transcripts of audio-only media — they can complete the task without hitting this wall.
Who is affected
Deaf people who need transcripts of audio-only media, and blind people who need alternatives to silent video.
