I'm ok with both - I have favorite examples for voiced (female sarcastic Hawke - best character ever) and silent (apart from BG, my favorite is Malkavian from Vampire Bloodlines - there the silent treatment worked pretty well) protagonists and I can see the pros for both sides. I could live with what they are doing in the EA - have a few voiced lines and the rest is silent. But I'm ok with fully voiced too.
