Live Webinar Audio With No Real-Time Captions

1.2.4 — Captions (Live)

Scenario

Setting

An e-book reader's library page

What’s wrong

Live stream/webinar with audio and no real-time captions (live human captioning (CART) or quality auto-generated (speech recognition)).

Example

Try this on an e-book reader's library page: live stream/webinar with audio and no real-time captions (live human captioning (CART) or quality auto-generated (speech recognition)).

Why it matters

Deaf and hard-of-hearing participants in live streams, classes, and meetings. The practical effect on an e-book reader's library page: they get no equivalent for the sound or picture content.

How to test

Join the live stream and check for a captions option (CART or live speech-to-text): if entirely absent, it fails.

How to fix

Readable, reasonably accurate real-time captions must run for the entire live event.

Outcome

That one change on an e-book reader's library page means they get the same information as everyone else.

Who is affected

Deaf and hard-of-hearing participants in live streams, classes, and meetings.
