NPR Pioneers Captioned Radio

Girl listening to radio
On Election Night 2008, NPR Labs demonstrated their captioned radio technology in Boston, Maryland, Washington, D.C., Denver, and Phoenix. Now they are demonstrating a unique dual-view screen in the car, which allows passengers to view captioned radio while the driver sees navigation information and hears the audio of the radio.

This captioned video on Youtube does a good job of demonstrating the technology, although it does not go into specifics about how the captions work. While watching the video demonstration of the car technology, it's apparent that the captions are slightly behind the audio.

According to a press release from NPR, "The technology takes advantage of digital radio transmissions to send a closed-captioned transcript of a live broadcast to the screen on a specially built receiver." I wonder what happens when people deviate from the script. It would be neat if this has built-in automatic captioning via voice recognition the same way Youtube's videos do.

NPR also has new technology out for people who are blind or have low vision. It's called Personalized Audio Information Service, and it allows these people to have greater choice in choosing their radio programming by subject. It would also ensure that HD radios can alert listeners to emergency messages.
