A potential goldmine of content might be just the press of a button away if you’re a language learner who wants to pick up a language through watching and listening.
Audio description, also known as described video, video description, or visual description, adds a narrator’s description of precisely what’s happening on the screen to a program’s soundtrack.
Audio description is primarily intended to benefit people who are blind or visually impaired by making the visual content accessible to them through hearing.
What appears to be overlooked is its tremendous value as a tool for language acquisition.
By providing a great source of comprehensible input—language made understandable through context—audio description also makes the target language more accessible to language learners.
