His neck and collar appear to be doing the same thing in this video from 2009. There are even moments here where it looks like a mask, so - probably not a mask. I am also not convinced that mask tech is actually this good, or that the voice could also be imitated. And then to try to do this with all these different people? A fake Biden mask, a fake Fauci mask, a fake Pelosi mask? I’m not convinced that could be pulled off. Deep fakes over Zoom with some sort of voice modification would seem to be more achievable, but even then, I’m not sure how effective or consistently believable that would be.
