You're perfectly right about the irritating tone of his voice, i was so annoyed i turned the voices off for a while, and i never complained about any voices in games before, i was ok with the voices in the demo, even liked them, also i liked the voices in the original divine divinity.
Just play some more and you'll see the stupid tone of his voice changes for the better, it gets to the point where it sounds beter than the demo, im quite happy i had the courage to turn the voices back on after the initial shock :P
