> Does it need a hardware synth? Yes. It supports a bunch of them, some better than others. It works best with the Doubletalk group. It also works well with audapter and the old artic boards with sonix+tts+porttalk, and it supports some prehistoric synthesizers you probably never heard of such as the Intex Talker and the Votrax Personal Speech System. The best thing about provox is its cost. It is free.
