I think a great tool for this would be a cross over voice changer AI, so you could still speak naturally but then sound like the model voice, that way it would be a little less soulless.
Honestly, that would be incredible for so many purposes! vTubers and amateur media creators would love to be able to just speak and have it translated into their voice of their characters in a more natural way!
Would also be an interesting one for theme parks, since it could led the costumed characters speak in the voices of the relevant characters rather than remaining silent, which would add a lot to the sense of immersion there too. (something like the website on the other hand could let the animatronics, CGI characters and others hold conversations with guests too, which would also be neat)
