Audio Description (AD) / Described Video (DV)
Audio Description or Described Video is an essential accessibility feature designed to make visual content accessible to people who are blind or partially sighted. It works by adding a secondary audio track to a program, production, or video. This track provides verbal descriptions of key visual elements that are important for understanding the storyline, such as:
-
Character movements and actions: "The woman steps forward and raises her hand."
-
Facial expressions and emotions: "He frowns and appears concerned."
-
Setting and environment: "Old furniture fills a bedroom."
-
Scene changes or transitions: "At night, traffic flows past a busy street corner."
These descriptions are carefully timed to fit between dialogue, and important music and sounds effects, ensuring they don't interfere with the integrity of the media. Descriptions enable users to follow along with visual content in a way that is both informative and seamless, making entertainment and information more inclusive.
Applications of Audio Description:
​
-
Film and Television: Providing detailed descriptions for movies and shows, often through a dedicated audio track or streaming platform feature.
-
Live Performances: Delivering real-time descriptions during theater performances, ballet, and opera, usually trough a dedicated headset or app.

Audio Description/Described Video not only benefits people with disabilities, but can also enhance the experience for those who are learning English by clarifying complex visual concepts. It’s an important step toward making digital and cultural content universally accessible.
