Audio Accessible Alternative Check
Description
The “Audio Accessible Alternative Check” evaluates whether there are <video></mark> elements containing audio content (e.g., speech or meaningful sounds) and whether they provide an accessible text alternative, typically in the form of captions.
Example outcome
I noticed that there is 1 <video></mark> element with audio content that must have an accessible alternative.
Impact
- Auditory Disorders: Without captions, users with auditory disorders cannot access spoken content or key sounds.
- Non-Native Speakers: Captions support language comprehension and clarity.
Fixes
To address missing audio accessible alternatives:
- Locate the inappropriate
<video></mark> element. - Provide captions for the audio (e.g., adding a
<track></mark> element within the<video></mark> tag).
