What this means
Captions show a video's speech and important sounds as text at the right time. They must be accurate. An audio-only recording needs a written transcript so people can read its information without hearing it.
Passing examples
- A video has accurate captions timed to the speech.
- Captions identify a different speaker and an alarm sound that matters to the story.
- A podcast has a complete, accurate transcript available beside it.
- Automatic captions have been checked, including names, prices, and dates.
Failing examples
- Captions change 'fifteen pounds' to 'fifty pounds'.
- A video contains speech but has no captions.
- A podcast has no readable transcript.
- Captions appear well after the relevant speech, making the exchange hard to follow.
A separate transcript does not replace synchronized captions for a video with speech.
