The FCC is currently investigating closed caption radio for the hard of
hearing. WGBO and NPR are working on this project. Any thoughts? Is
it pretty easy for stations to convert their sound stream into
captioning. I wonder if anyone knows what kind of changes in receivers
we would need. The newer radios already type song titles and station
id's.

There was a time when subcarriers on FM stations was used for text. I can't
remember how experimental it was, but there were even experiments on using
it to deliver computer programs.

Like a lot of things, doing it is likelier easier than implementing it.
First they have to figure out a standard, convince companies to sell
such radios (or adaptors). Even if the radios can be dumb, and a nearby
computer used for the decoding, it will still require a radio with an output
jack to feed the computer.

And of course, someone will have to do the translation to text. That will
require funding.
