Reminds me a lot of CeVIO in terms of sound quality, but without the super-hard consonants. The voice is bit breathy, but it's very smooth. I don't know enough Chinese to really evaluate its clarity, but it sounds nearly like a real person, aside from a few weird transitions and vibrato - which honestly might just be weird tuning.
I'll have to run the program myself later to really get a feel for it, but I see a LOT of potential here!
