Success Criterion 1.2.2
Conformance level A

Captions Translated Into Another Language Instead of the Original

1.2.2 — Captions (Prerecorded)

Scenario

Setting

A weather app's forecast screen

What’s wrong

Captions in a different language than the audio (only translated subtitles, no same-language captions).

Example

<video src="demo.mp4"></video>

Why it matters

Deaf and hard-of-hearing viewers, and anyone watching video without sound.

How to test

Turn on captions and compare their language to the audio's language: if only translated subtitles exist with no same-language captions, it fails at Level A.

How to fix

Synchronized captions must be provided covering all dialogue, speaker identification, and important sounds.

<video src="demo.mp4">

  <track kind="captions" src="captions-en.vtt" srclang="en" label="English">

</video>

A <track> element with kind="captions" surfaces synchronized text for dialogue and important sounds.

Outcome

On a weather app's forecast screen, this barrier is gone for deaf and hard-of-hearing viewers — they get the same result as anyone else here.
