1.2.4 — Captions (Live)

Level AA Perceivable

Operational summary

IF live synchronized media includes audio, caption that audio. Review actual live output, speaker identification, synchronization and meaningful sounds; a future transcript does not meet the live-caption obligation.

This is an original implementation summary, not replacement normative text. The sources below supply the precise requirement, its definitions and its qualifications.

Primary sources

• Normative text — W3C WCAG 2.2 Recommendation
• Understanding 1.2.4 — explanatory guidance

Registry record

Applicability and assessment start unset by design — no product has been evaluated. Instantiate the entry for an actual product, assign an owner and retain evidence.
