8.3 WCAG 2.1 Success Criterion 1.2.2 − Captions (Prerecorded)

Provide captions for audio tracks so that they are accessible by persons with hearing impairments. Captions not only present the content of a conversation but also important cues and surrounding noises.

Before Rectification

An image of an audio player.

When an audio is embedded in a webpage, the audio is only usable by people who can hear.

After Rectification

An image of an audio player containing text captions.

Text captions as shown in the example above should be provided so that a person with hearing difficulties can still access the content of the audio.
