WCAG 2.0 AA Compliance

Section 1.2.2

Captions are provided for all prerecorded audio content. This allows hearing impaired users to access the captions that are stored directly within the audio track.

This is for scenarios when you are providing an audio-only track that contains things like:

  • an audio book
  • a set of verbal instructions
  • a narration
  • music

This section is also for scenarios when you are providing a full video with audio, such as a YouTube video. It is highly recommended that you use a familiar and popular interface such as YouTube to provide your videos as they have a very user-friendly method of adding captions to videos. CaptionTube is a great place to start with your closed-captioning needs.

It is usually difficult to provide a cross-platform method of closed captioning for a pure audio source with no video. The best method to satisfy this requirement is to provide equivalent content that matches or exceeds the information that is provided in the auditory track. If the auditory track is being provided as an alternative to text-based content, you must clearly indicate this. Otherwise, you may provide SAMI and SMIL files for use with Quicktime, RealPlayer, and Windows Media Player. See the below references to provide this.
