I would prefer silent since I find it more important what my character is saying, than how they sound when they are saying it, since i believe that a voiced protagonist makes it hard to have as many dialouge choices as i would prefer.
With that said, i don't think Larian will bless us with that much more dialouge in the full release, so they might as well record the pitiful few dialouge choices that do exist. With a toggle to mute your protag if the voices doesn't fit their character.
