I think the question is about a "documentary" using synthesized voices presented as if they are recordings. You'd have the same issue with impersonation by a human; it is presenting one thing as something it is not. Getting away from the specifics of this case, cheap impersonation of arbitrary individuals getting easier raises lots of questions... all those TV spy shows "voice print cloning" stuff becoming more real will make a lot of things involving non-face-to-face trust more interesting.
