I hate to be the stick in the mud, but I'm not a huge fan of full voice acting in RPGs, especially cRPGs like this where dialogue and text make up a large portion of gameplay. It's a huge expense that imposes restrictions about the game, and personally I've always been a fan of audible speech being something important and uncommon.
That said, I understand why they did it for DOS2 and can appreciate it, the majority of the voice actin is quite good, or is at least bearable.
