THIS is the update I've been waiting to hear about! I asked in one of the developer livestreams over two years ago if they'd ever consider doing real-time voice synths for player names, and one of them said in chat that they were already testing it internally. I never heard anything else about it since then, so I figured they abandoned the idea. I'm glad they're finally doing it!
Really curious to know their solution to the OBVIOUS problem. I have to imagine there's some sort of approval process before the game will say your name.
