I didn't have a problem with it, although when I first started playing the alpha all I could think of was Tyrion. However either for the beta or the full game release I have no doubt that they will put some type of effect of Peter's voice to make it sound more like a robot as him talking in his regualr voice isn't very robot like. Even if they dont add effects to Peter's voice it wont be a massive problem as after a while you'd just it. I'm pretty sure they will change it up in some way though.
