WCAG 1.2.2: Captions (Prerecorded)
WCAG 1.2.2 requires that all prerecorded audio content in synchronized media (video with audio) includes accurate captions. This ensures deaf and hard-of-hearing users can access spoken dialogue, sound effects, and other meaningful audio information.

WCAG 1.2.9: Audio-only (Live)
WCAG 1.2.9 requires that all live audio-only content — such as live radio broadcasts or audio-only streams — be accompanied by a real-time text alternative equivalent, such as a live captions feed or text transcript updated synchronously. This ensures that users who are deaf or hard of hearing can access live audio content without relying on the audio track itself.
