E3 2019: How Does "Play As Anyone" Even Work in Watch Dogs Legion?

This could be amazingly cool and i'm getting "State of Decay on Steroroids" vibes from this. It seems too good to be true though. How would they record enough different voices for this to feel like its not a GTA Online style silent protagonist? Color me seriously impressed if they pull this off though.

All old lady gang, here I come.

This is some bananas, pie in the sky sounding nonsense. I'll be really impressed if they manage to pull this off.

@livevil999: Brad said that they use a lot of different versions of the script + voice modulation, and then algorithms to line it all up. So they may have written 12 different ways a conversation in a cutscene can play out, and said it's possible to have two people in a cutscene played by the same voice actor without it being noticeable. So it doesn't sound totally unfeasible.

To me the unbelievable stuff was how the cutscenes in the demo were reacting to the game. Like in a scene from this video when the hacker recruit asked "So what happened to that other guy" referring to how the earlier character died. I don't really see a way for that to be possible, in every cutscene, even if they've written 12+ versions of the script.
