Provide audio descriptions for pre-recorded videos.

Introduction

Users with visual impairments or cognitive limitations may rely on audio description to enjoy videos. Adding an audio description soundtrack to videos means these users get all information from the content.

How to Pass

  • Provide an audio described version of a video’s soundtrack, selectable by the user; or
  • Provide an alternative version of your video with audio description.

Exceptions

You don’t need to add audio description if your video conveys all its information through the regular soundtrack. Something like a straight face-to-face interview, or a speech to-camera would probably not need audio description.

Tips

Audio description is an edited version of a video’s soundtrack that adds more information than the regular soundtrack offers during pauses. This might mean narrating movements that are not audibly explained in the video, identifying speakers or explaining visual information. You can provide this to users by letting them select an audio track within the video player or having links to both versions of the video.

Keep this guideline in mind when creating videos to reduce your workload.

If you provided audio descriptions for videos to meet 1.2.3, you’ve already fulfilled this guideline.

This doesn’t apply to live videos or streaming.

Introduction

Users with hearing impairments may rely on captions to enjoy your video content. Adding captions to live videos helps people use your website when you’re streaming live video.

How to Pass

Add captions to live video.

Tips

Include presenter cues and important sound effects as well as dialogue.

Depending on the software you’re using to stream, it may have a built-in auto caption option or you may need to link up some 3rd party captioning software.

This is a difficult and potentially expensive guideline to meet. Broadcasters like the BBC hire professional subtitlers to add captions to live television.
