This stuff is very labour and memory intensive and I couldn't even get the voice cloning software to train from scratch due to error messages that required coding knowledge to resolve. I can now see that there are two other voice cloning models that didn't exist a year ago, neither one of which looks any more user friendly than the one I tried. I really couldn't face removing the one I tried and all the pre-trained models, loading on a new one, and then going through all that effort again for a different set of error messages for the three vocoded sentences I needed.
The fact that the software is so open to abuse is probably why they are never going to make it user friendly. I don't think it is going to revolutionise TV or movies. It is what is. If you work in the industry or if you have the spare time, you can have some fun with it making memes or some such. You might get uber-fans dubbing Grand Moff Tarkin in a vocoded Peter Cushing voice or something silly like that.
Hell, I'd even be willing to pay someone to do the 5 lines of dialogue I need to 'perfect' my fan edit. And while I'm at it, I really hate Shatner's delivery of, "The question is, Mr Decker, is there a next move?" I bet a vocoder could deliver more emotion than Shatner for that line!
