AD commonly identifies audio description: narration of important visual information such as actions, scene changes or on-screen text. It is an accessibility feature, not a fault or a second commentator. Availability depends on the programme and the tracks supplied through the viewing service.
Listen for the purpose
Description often fills gaps between dialogue to explain what is happening visually. It can be selected deliberately by viewers who benefit from it. If narration starts unexpectedly, inspect the audio menu and the device’s accessibility preferences before assuming that the original soundtrack has been replaced incorrectly.
Choose the appropriate track
A programme may list a normal language track and a descriptive version of the same language. Select the one that suits the viewer, then check whether the app remembers that choice. A global preference can automatically select description when available, but cannot create it for programmes that do not include a descriptive track.
Keep access needs visible
When sharing a television, agree on preferences rather than disabling accessibility features without explanation. If a descriptive option is missing or does not play, report the exact title, language and app. Captions and audio description serve different purposes, so offering subtitles alone does not necessarily meet the same viewer’s needs.
