You already knew that you can turn on subtitles for your TV show or movie—handy if you’re hearing impaired, or just want to understand the dialogue better. But there’s a corresponding feature for people with low vision: audio description tracks, where an unseen narrator tells you, in real time, what’s happening on the screen. But who creates them, and how, and when? And how do they describe the action during fast dialogue, fast action, sex scenes, and screens full of scrolling credits? A deep dive into a bizarre art form most people didn’t know exists.

Guests: Lauren Berglund, consumer relations coordinator at the Guide Dog Foundation. Bill Patterson, founder, Audio Description Solutions. Rhys Lloyd, studio head, Descriptive Video Works. Bryan Gould, director of the National Center for Accessible Media at WGBH.
