Audio Description Track With No Way to Turn It On
1.2.3 — Audio Description or Media Alternative (Prerecorded)
Scenario
Setting
A language-learning app's lesson screen
What’s wrong
audio description track exists but the player provides no way to select it.
Example
A tester reviewing a language-learning app's lesson screen finds this: audio description track exists but the player provides no way to select it.
Why it matters
Blind and low-vision viewers who hear dialogue but miss unique visual information. On a language-learning app's lesson screen, that means they get no equivalent for the sound or picture content.
How to test
Check the player controls for an audio-description toggle: if it exists but doesn't actually switch on a described audio track, it fails.
How to fix
An audio description or a full descriptive transcript covering all important visual information must be provided.
Outcome
With the fix in place on a language-learning app's lesson screen, they hear or read what the media conveys.
Who is affected
Blind and low-vision viewers who hear dialogue but miss unique visual information.
