Audio description, also known as descriptive narration or video description, is an accessibility service that provides a spoken description of the visual elements of a television program or movie. It is designed for people who are blind or have low vision, and is typically delivered through a secondary audio channel.
Audio description can be beneficial for people with vision impairments by providing them with information about the visual elements of a program that they would otherwise miss. For example, it can describe the setting of a scene, the appearance and actions of characters, and the overall plot of the program. This information can help people with vision impairments to better understand and enjoy the program.
