Captioned Radio?

Out of curiosity, I was wondering if they even come up with something for those who are hearing impaired. And there are a lot of them. According to the Survey of Income and Program Participation (SIPP), nearly 10,000,000 persons are hard of hearing and close to 1,000,000 are functionally deaf.

I found this:

PC Magazine reports that Harris Communications has worked with partners to develop a means of captioning radio for deaf listeners. It is not the first time this idea has been thought of, but it is progress that an actual system has been developed, and demonstrated. The system is aimed at "talk radio."

The systems works a lot like close captioning does for television. So, I thought that is a neat idea but then again, it would be very difficult to "read" a radio while driving, cleaning house, getting ready in the morning or doing other tasks that requires our eyes.

I don't think it will be a huge success because since deaf people are VERY visual, we rely on our eyes on everything, so if we had to choose between captioned radio or captioned TV, all of us would choose TV without any hesitation.
