Video’s Narrated Audio Track Skips Key Visual Details
1.2.1 — Audio-only and Video-only (Prerecorded)
Scenario
Setting
A community forum's discussion thread
What’s wrong
Video-only media whose audio-track alternative doesn't describe all important visual information.
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
Read the audio-track alternative for a video against the video itself: check it also states what's shown on screen, not just what's said.
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 community forum's discussion thread, this barrier is gone for deaf people who need transcripts of audio-only media — they reach the same outcome without extra effort.
Who is affected
Deaf people who need transcripts of audio-only media, and blind people who need alternatives to silent video.
