I know we can create vaguely convincing synthesised voices, but I've not run across a program which can take my recorded voice, and convert it to a celebrity, or even shift apparent pitch or gender convincingly.
BTW, we can create extremely convincing synthesized voices: https://google.github.io/tacotron/publications/tacotron2/ind...
I think I've just gotten so used to that voice as the "google" voice that I automatically associate it with computers. It would be strange to meet the human that was providing the human voice in those samples.
Now imagine that with Tacotron quality, and you'll get that "strange" effect with anyone, meeting their vocal clone.
This is still text-to-speech, so it's not live-copying your intonation, but you could easily imagine a seq2seq network designed to do so.
I did have a fever at the time, which might not have helped.
Hence, if I could find a program which could reliably turn one actor's voice into another, I could use their acting ability, but with more characters and less requirement for them to "put on" voices. That's powerful because really good actors are thin on the ground, and also because trying to hold a different voice or accent can limit the quality of the main performance.
