Lesson overview · Captions (Live)
In plain language
Live streams with audio need real-time captions.
Who it affects
Deaf and hard-of-hearing participants in live streams, classes, and meetings.
How to check
Join a live event and confirm readable, reasonably accurate captions run throughout.
Common misconception
Auto-generated live captions from a webinar platform are a starting point, not a guarantee. Heavy accents, jargon, or fast speech can push accuracy too low to be usable without a human captioner.
