Fix "Video without captions" in HTML
Why it's a problem
A video whose soundtrack carries speech or meaningful sounds is inaccessible to Deaf and hard-of-hearing people without synchronised captions — and to anyone watching muted. axe-core cannot tell whether the video speaks: it reports a missing captions track as an item to review, not a certain failure.
How to fix it — HTML
Add a <track kind="captions"> in WebVTT format, synchronised and faithful to the dialogue, with meaningful sounds in brackets. Proofread auto-generated captions before publishing: recognition errors sometimes change the meaning. A video with no speech or meaningful sound does not need them.
