Provide alternatives for live audio.

Introduction

Some users with hearing impairments may rely on alternatives to enjoy live audio-only content.

How to Pass

  • Add captions to live audio; or
  • If the live broadcast is from a prepared script, make the script text available from near the original content.

Tips

To add live captions to an audio broadcast, you will need professional software and a trained operator. This isn’t a job you can accurately perform without training.

Provide a text alternative to pre-recorded videos.

Introduction

Users with visual and/or hearing impairments may not be able perceive the information in a video from its soundtrack or captions.

How to Pass

Provide a full text transcript for your video and link to it from near the original content

Exceptions

If the video is itself an alternative, you don’t need to add a transcript.

Tips

You may have fulfilled this Guideline if you chose to meet 1.2.3 – Audio Description or Media Alternative (Pre-recorded) with a text transcript.

A good transcript contains all information in the video, such as visual cues, description and dialogue attribution.

Provide extended audio description for pre-recorded videos.

Introduction

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

For videos where there’s more information to convey than the natural pauses in the soundtrack allow you, those users need an extended audio description soundtrack.

How to Pass

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

Exceptions

  • You don’t need to add audio description at all 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.
  • You don’t need extended audio description if regular audio description can provide all of the information in the video during the natural pauses in sound.\This guideline doesn’t apply to live videos or streaming.
  • Live videos and streaming.

Tips

Extended audio description builds on audio description by effectively pausing the video to give the soundtrack enough time to pass one all the information from the video. This might mean narrating movements that are not audibly explained in the video, identifying speakers or explaining visual information.

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

Provide sign language translations for pre-recorded videos.

Introduction

Users with hearing impairments can benefit from seeing a sign language translation of your video soundtracks. In fact, those whose first language is a sign language may have limited reading ability, meaning captions can be difficult to follow.

Sign language is also faster to interpret than written captions and can convey emotion and tone much better.

How to Pass

Make an alternative version of your video with a sign language interpreter either present in the main video or embedded as picture-in-picture and link to it from near the original content.

Tips

An obvious issue is the question of which sign language to use. Forms of sign language are often exclusive to a particular country; even British and American sign languages are completely distinct, despite the similarities of the written language.

The best bet is to provide sign language in the language of the country that you are targeting, or if you are multi-national, in the language of the country of the highest proportion of your visitors.

You’ll need to find and hire a sign language interpreter for your videos.
