I think the main problem with voices , at least for me, is variety. If the game had for example: islander, gritty, deep, young, old, middle age, tone influence, demeanor, softcore, hardcore, etc I don't think it would be as much of a problem. Add in the disable voice and partial voice options and you have at least partly an immersive character.

I mean in the end I'll play the game regardless but those options would really take it to the next level.
