For gaming, AI opens up the possibility of true reactivity with fully voiced and even emotive npc characters. A whole village of them. An entire world of them. Factions of them. Each one has a set of coded morality and other defining characteristics, drives, backstories and…boom…you basically have a holodeck from Star Trek.
I think that is very exciting!
I don't like it when AI kicks people out of jobs. Voice acting, however, is criminally underpaid work.
A big pro for me in gaming is that characters might finally sound the same. I hate it when the German lines are OOC. Almost always, the voice actor brings an execution contrary to the og... or sounds just too different. Petty as hell, I know. I've been mad about it for more than half my life. Seems there's no growing out of it.
