That's cool, but I guess I was specifically looking for something more advanced than basic text-to-speech (which most browsers nowadays have built in and can be achieved in 2 lines of JavaScript[0]). I was specifically looking for high quality natural speech sounding generated audio.
Cool app. The biggest issue for me is the voice sounds very much like the typical system voice apps, when we are seeing such leaps and bounds in the voice quality. But your interface is simple and nice.
