How to fix: video without captions

Deaf users cannot access audio content. Captions transcribe both speech and meaningful sound.

WCAG references
1.2.2

Critical

What it looks like in the wild

Deaf users cannot access audio content.

The screen-reader user, keyboard user, or low-vision user encountering this issue does not get an error message. The page just stops working for them. Which is why this kind of bug rarely shows up in your error tracker; it shows up in support tickets, lawsuits, and abandoned conversions.

Why it fails WCAG

Captions transcribe both speech and meaningful sound.

Map this back to 1.2.2 when you log the bug. Auditors and procurement teams expect that mapping; "broken" is not enough context.

The wrong pattern (avoid)

HTML
<video src="/promo.mp4" controls></video>

The right pattern (copy this)

HTML
<video src="/promo.mp4" controls>
  <track kind="captions" src="/promo.en.vtt" srclang="en" label="English" default>
</video>

Notes from real audits

  • YouTube auto-captions are not WCAG-compliant on their own; review and correct.
