Text-to-speech

This is something I will have to implement for a realistic Tower simulator, the planes will have to talk to the user, and vice-versa. On the planes side, their calls are coming from text and will need to be transformed into voice. There are several text-to-speech egines out there, but I came upon one (NeoSpeech) that completely blew me away. It almost sounds like a human being, scary!

I'll be looking into this and other engines.
