Nope. Everything is hand crafted according to the developers.
Here some quotes from developers
"If by "algorithm" you mean "hand crafted every and each scene, both body and facial animations" - you are right! : )
The whole thing is somewhat complicated, and I was thinking lately of doing blog post about that. We shall see."
"Hi there! Actually, there's no facial capture in the game - apart from one tiny moment, IIRC. Everything else is hand made and hand placed. Layers and layers of hard work. : ) We have also extensive animations library which we use in the dialogue scenes - many of them are also keyframed, and all of them are hand placed and tweaked. Just like facial animations."
