Audio description

Summary

Audio description (AD), also referred to as a video description, described video, or visual description, is a form of narration used to provide information surrounding key visual elements in a media work for the benefit of blind and visually impaired consumers. These narrations are typically placed during natural pauses in the audio, and sometimes overlap dialogue if deemed necessary. Occasionally when a film briefly has subtitled dialogue in a different language, the narrator will read out the subtitles.
