Text documents that provide descriptions of important visual information and transcripts of important auditory information


Provide a single document that combines text versions of any media equivalents required by Guideline 1.2, including captions and audio descriptions, in the order in which they occur in the multimedia.

Transcripts also provide the ability to index and search for information contained in audio/visual materials.
