I was under the impression -- although I could be quite wrong here-- that the intention is to have the main character fully voiced by the end of development, its just not fully implemented yet. What with all the voice options there are, that's a lot of lines to deal with adding in at the current stage of early access. I also wouldn't be surprised if the devs wanted to collect some Feedback on the subject since some people seem to want silent protag entirely, but thats just my guess. Am curious if there are any official words on it that I've missed.
The one cutscene I came across where my character actually spoke in response to something (with camera actually up close on him) I admit threw me off a little but I wouldn't hate having the whole game be like that.
