"Being blind doesn’t mean you can't, you know, listen." - Stevie Wonder
Audio Description makes visual media accessible to people who are blind and visually impaired. It’s a secondary audio track with a narrator describing key visual elements that are inserted into natural pauses in the dialogue. Different terms are used in different countries, but the meaning is the same.
The term audio description (AD) is commonly used in the United States, the United Kingdom, Australia, China, Europe, The Netherlands, Scandinavia, India, Korea and New Zealand. In Canada, this process is known as descriptive video (also referred to as DV, video description, described video or described narrative).
THE AUDIO DESCRIPTION PROCESS
Turn-around will vary with type of content, (a dialogue-dense film leaves less space for Audio Description and requires less time to create).
