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.
