Sure thing!
Plus you'd have the choice of playing an Orc or a deranged human (shell shocked kinda deal) but if you wanted to do it, you'd be given an array of scripts for a host of different characters, which i'd run through a pitch shift to change them slightley.. That'd be just for things like backing ambience etc.
I'll run through the script i have and find some relevant things for you to say, and then just plonk them on here!
