Yesterday, his voice was normal. He's human, and he sounded human.
Now, it sounds like his voice has been filtered, almost as if he were one of the holograms throughout the game. It sounds robotic, and it kind of hurts my ears to hear him talk. I've been playing this game for several days now, and this is new. The problem didn't go away when I closed the game out and reloaded it, either.
EDIT: I meant for this to go in the Bug Reports section.
