Audio-only (Live)

For live audio-only broadcasts, provide a live text version so deaf and hard-of-hearing people can follow along.

In plain English

If you broadcast live audio with no video, like a live audio room or an audio-only launch event, deaf and hard-of-hearing people cannot follow it. This AAA rule says provide a real-time text version: a live captioner typing along, or, if you are reading from a script, the script published as text.

Most stores never run live audio-only content, so this often does not apply. Live video shopping streams fall under different (caption) rules.

Who this is for

  • Deaf and hard-of-hearing people trying to follow a live audio broadcast.

How to check and fix it yourself

Do you ever go live in audio only? If so, arrange live captioning, or post the prepared script as text at the same time.

Live audio event → live captioner typing in real time.   ✓
Reading a prepared script → publish the script as text.  ✓
No live audio-only content → not applicable.

Where we can help

We identify whether you run any live audio-only content and, if so, what real-time text option fits your setup. It is a rare case but part of covering every media rule.

Frequently asked questions

What does audio-only (live) require?+

Success Criterion 1.2.9 (Level AAA) says a live audio-only stream (like a live podcast or audio-only broadcast) must have a text alternative presented in real time, so deaf and hard-of-hearing people can read what's being said.

How do you caption something live?+

Either with a live captioner (a person transcribing in real time, sometimes called CART) or, if the audio follows a prepared script, by publishing that script as text alongside the stream.

Does a typical store need this?+

Only if you run live audio-only events, which is uncommon for stores. If you host a live shopping stream (which is video), the relevant rules are the live-caption ones instead. This criterion is specifically audio-only and Level AAA.
