Long Description That Doesn’t Match What the Audio Actually Says

1.2.1 — Audio-only and Video-only (Prerecorded)

Scenario

Setting

A nonprofit's donation form

What’s wrong

The long description provided for an image doesn't actually convey the same information as the image itself.

Example

A nonprofit's donation form runs into this exact issue: the long description provided for an image doesn't actually convey the same information as the image itself.

Why it matters

Deaf people who need transcripts of audio-only media, and blind people who need alternatives to silent video. On a nonprofit's donation form, this barrier means they are left guessing what the media actually shows.

How to test

Open the linked long description for the audio/video-only media and compare it point-by-point against the recording: gaps mean it fails.

How to fix

Make the long description convey the same information the image conveys.

Outcome

Corrected, a nonprofit's donation form now lets a visitor understand the image, video, or audio content.

Who is affected

Deaf people who need transcripts of audio-only media, and blind people who need alternatives to silent video.
