Audio Description Script

An audio description script is the written text that forms the basis of an audio description track for video content. The script contains narration that describes visual elements — including actions, scene changes, character appearances, on-screen text, and other visual information — timed to fit within natural pauses in dialogue and other audio. Writing effective AD scripts requires balancing completeness of visual information with brevity to fit within available gaps, and prioritizing the most essential visual details for understanding the content. Scripts can be narrated by professional voice actors or, increasingly, rendered through text-to-speech synthesis, which lowers production costs and enables iterative editing. Text-based AD script formats allow scripts to be stored, shared, and applied as external metadata independently of the original video file.
