I dit buy it and tested it. At this moment all I can say is that it doesn't work. Nor does it work on Poser Pro (the current one, not tested on 2010).

Running on a Vista Ultimate 64 environment. It tells me it creates all the frames and spends a long time without any error messages but afterwards none of the animation frames exist and the number of frames has not been extended.

Shame it looked like a usefull utility, combining actual generation of speech and creating all appropriate animation frames, including blinks and head movement.
