Why not just have the option to have a fully voiced player character and for those who don't want that give them the option to turn it off. People have posted that Larian has said that the pc will eventually be fully voiced though that idea maybe scrapped or still being worked on. I personally find it distracting that our pc is a mute for a lot of the conversations and it takes me out of the game and just makes it look awkward. It was one of the few things I didn't like about Dragon Age Origins.
