1.2.4 Captions (Live)
Live video with sound, such as webinars and live streams, needs real-time captions.
Who it helps
Deaf and hard-of-hearing people.
Failures we see most
- Live webinars with no captioning
- Town hall streams that only get captions in the recording afterwards
How it gets tested
No automated tool can judge 1.2.4 reliably, so a specialist tests it by hand, with a keyboard and a screen reader where that applies.
How we fix it
A specialist fixes this in your site's code or content, and we re-test the page before you sign off.
