I envision a day when even normal hearing people wear hearing aids and have assisting devices to give them essentially super-hearing, or more selective hearing. It's kind of strange being profoundly deaf, but having situations where I can actually hear better than my friends, because my hearing aid filters out things!
Edit: I played around with it a bit by myself. It seems to work as well as any other text-to-speech, but I do like the interface. I'll test it out more this week and see how it goes!
Otherwise looks great!
