Yeah, I was just showing the other day to few friends the current project to voice all NPCs in Morrowind using AI-generated voice over.
This stuff is improving at an almost-alarming rate, too, so what may sound "more or less convincing" today will be basically flawless "few papers down the line" (cit.). Even in its current state, a lot of the lines in the video I linked are already fairly better than a lot of cases of amateur voice acting done for modding purposes... Or past cases of bad voice acting in gaming, in general.
There's also a vast range of possible applications, too. For instance in the past I've been really vocal (hehe) about the fact that expecting a fully voiced protagonist in BG3 will all the possible permutations of who the MC can be available would be unreasonable. But now imagine if they just had to register one male and female variation for the MC and then they could use AI to over-impose alternate vocal timbers on these lines. The cost would be grought down immensely, if with a marginal compromise in quality/unicity of the output, while the feasibility would improve dramatically.
Its exciting to think what Morrowind will look like in the near future, the recreation projects have already reached a point where they're adding new areas, quests, and characters to the game, and now they have tools to create them fully voiced. I watched another video of Vivec fully voiced and I have to admit it was long enough ago, that I wasn't sure if Vivec had any voice acting to begin with, probably the perfect place to start working original voices in. With a few mis-reads it was as good as anything in the original game. (Probably better in fact)
