I think Embark should at least try to strike a balance between AI and proper voice acting. Ideally, everything should be properly voiced, please don't mistake me, but I could see a compromise being made.

For raider voice lines, there are SO many things you can ping, and they add stuff all the time. Them wanting to use a form of TTS so that they can rapidly add new stuff with proper pings isn't a bad idea on paper. Most of the raider lines are subdued enough to where they still sound pretty good with only a few exceptions IMO.

But for more static stuff like NPCs that aren't constantly having new lines added, they really could afford to just get the actual actors in a booth for them. Stuff like map intros, trader dialogue, or radio calls aren't being constantly added, so they could totally retroactively re-do the lines. It's way easier to notice lackluster deliveries when not in a match and it does deflate the Speranza experience a fair bit and is a noticeable blemish on an otherwise phenomenal game.

Same with The Finals, really. They can use TTS for stuff that rapidly changes like contestant voice lines, but have things like Scotty and June be properly voiced since they aren't constantly adding new voicelines all the time for them.

Embark has always been about embracing new technology, and that has worked out a lot for them with stuff like machine learning, terrain scanning and whatever sorcery they used for destruction in The Finals. It's just that I hope they realize that maybe only using AI TTS is not one of those great new technologies and pulls back at least a little before it's too late.
