WCAG 1.2.9: Audio-only (Live)
WCAG 1.2.9 Audio-only (Live) is a level AAA success criterion from WCAG 2.0. Live audio needs a text alternative, such as a live transcript.
Deaf people cannot follow a live audio announcement of stock or a radio-style sale.
How to test
During a live audio event, confirm a transcript updates as people speak.
How to fix
Run live transcription and show it on the same page as the player.
Example that fails
A live restock announcement is audio only.
Example that passes the check
The page shows a live transcript beside the player.
Shopify
Embed the transcription-capable player in a page section and link it from the announcement bar as text too.
WooCommerce
Put the live transcript embed under a heading on a dedicated page.
WordPress
Use a page with the player and the transcript embed, both labelled.
Wix
Add the transcript embed under the audio player with a heading.
