What is Audio Description?

Audio Description makes the visual content of any media accessible to blind and low-vision audiences. Description is the act of adding a secondary audio track that describes actions, settings, and other visual details so that blind and low-vision audiences can have the same experience with media as someone who is fully sighted.

Describers write a script consisting of vivid and succinct descriptions, timed during natural breaks in the dialogue and other audio. Narrators then record voiceover of those descriptions to be mixed into the soundtrack, creating a descriptive audio track that can be selected by the user.

What is Expanded Audio Description?

With Expanded Description, a video editor inserts pauses at key points , giving the describer more time to convey a full picture of the scene. This process extends the duration of the video, so it’s best suited to web-based content. If your video has constant dialogue with few natural pauses, then it is a good candidate for Expanded Description.

What is Live Audio Description?

Realtime audio description provides live narration of a program’s visual content as it occurs. Realtime audio description is a growing service in the accessibility world, as more and more organizations are providing for their blind and low-vision constituents a full audio description of their live media.

What is Text Description?

Text Description (also called a descriptive transcript or media alternative) is a document that includes both description of a video’s visual content and transcription of the audio. It is an alternative to the primary media, designed for use with screen readers or refreshable braille displays.
