To those complaining about the new voice acting being everywhere, there are settings in the options to change that.
"Full" means every line is voiced more or less (the little pop up thoughts you get walking around the map aren't, some of the descriptors of actions alongside someone talking aren't, but you usually get a Foley noise of someone sighing or snorting or punching a table if that's the action described).
"Psychological" means all the external characters are voiced, but your internal dialogs are not, if you subscribe to the "thoughts are instant not a conversation in your head" kind of thing.
"Classic" is basically the original game's voice acting frequency, when only key lines are voiced.
They all use the new voice acting recordings though, so Dot Major's performance as Cuno is gone.

The new voice actor is objectively better for accurately depicting a troubled 12 year old kid coming off of speed trapped in a hellish situation you can empathize with (after you punch). I have to admit its superior, but I'll nostalgically miss the original, inferior voice acting. It was extremely iconic.
The developers talked about the decision to make one voice actor say all the Skill's internal dialog in an article somewhere online (I read about it from second hand sources but never went to go find the article and look at it directly), I guess they were concerned that 24 different voice actors all screaming at you at once would have been hard to set the tone they wanted. Probably unspoken in that article would be how hard it would be to find 24 good fucking VAs, schedule them all in fun disease work times, make sure the audio quality was uniform and good working remotely, and probably even with the game's success all this might have been out of the small studio's budget.
Initially I was kinda put off with the one VA for all the skills, mostly because I had sort of invented how each talked in my head and it didn't line up, and it was weird to have these wildly different characters talk in the same deep voice with their conflicting viewpoints and behaviors, but I warmed to it eventually. I think its a different take on the protagonist, one that makes him seem more schizophrenic and fucked up, because its not different entities arguing in his head over whatever subject you're on, its just
him. Your protagonist is now more like the crazy homeless guy living under a bridge inebriated and having a passionate argument with nobody but himself, except that hobo is now your local law enforcement, and been given a badge, a gun, and authority, all of which he may not be the best at holding onto. Its actually kinda scarier and more off putting when you inadvertently thought of the skills as different entities.
