Having just listened to it, it's as distorted as the text is. I can't understand it myself, and the doctor said I have "normal" hearing. Nope, I don't think that passes muster at all. Lots of people will still be excluded. What about a blind deaf person using a braille browser? Such people do actually exist. Maybe it's fine with you if your sites don't work for them, but I think it's morally vacant, considering that the REST of the technology all works fine with it. I'm not talking about flying an airplane, I'm talking about viewing a web page!
