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 1.2.3: Audio Description or Media Alternative (Prerecorded)
WCAG 1.2.3 requires that prerecorded synchronized media (video with audio) provides either an audio description of the visual content or a full text alternative, ensuring users who are blind or have low vision can access information conveyed visually.
WCAG 1.2.6: Sign Language (Prerecorded)
WCAG 1.2.6 requires that sign language interpretation be provided for all prerecorded audio content in synchronized media. This criterion ensures that Deaf users whose primary language is a sign language can fully access audio information that may not be adequately conveyed through captions alone.
WCAG 1.2.7: Extended Audio Description (Prerecorded)
WCAG 1.2.7 requires that when pauses in foreground audio are insufficient to convey all visual information, extended audio descriptions—achieved by pausing the video—must be provided for prerecorded synchronized media. This ensures blind and low-vision users can fully understand complex visual content that standard audio descriptions cannot cover.
