I'm working on an indie online game that heavily uses text-to-speech, http://www.CircumReality.com . (It's far from done yet, but there is a little bit of content.)

Some comments about TTS:

- It won't take Ceptral long before they provide UI so an infinite number of voice variations can be made.

- It's possible to record your own voice (around 1000 sentences) and make a TTS voice from it. However, (a) other players would have to download the voice (which is 4-40 MB depending on the quality), and (b) Cepstral hasn't made that functionality public yet.

- In the long run, TTS for chatting between two players is far inferior to voice chat, barring some exceptions. You can even apply voice transformation/disguise to your voice-chat voice and do gender conversions.

- TTS is most useful for NPCs and game narration.

I've implemented cepstral voices before in a project. let's just say that they have good technology, but the voices are grating enough that AT&T starts sounding like a tempting alternative (even though an AT&T voice can cost several hundred dollars a seat)

Re: TTS versus voice morphing, I think that TTS does a better job at "maintaining suspension of disbelief" as Akela puts it. With voice morphing, you still hear your own voice, not the voice you have in mind for your avatar. And do morphing programs really make a reasonable gender changing voice? There's more to gender than pitch.....
