1.2.4 Captions (Live)

Level AAWCAG 2.2Manual testing only

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.
