CD Projekt used speech-cloning tech to revoice a dead actor in Cyberpunk 2077: Phantom Liberty
If you've ever spoken to the ripperdoc character Viktor Vektor in the Polish localisation of Cyberpunk 2077's Phantom Liberty expansion, you've been talking to a cyborg. Technically, of course, most characters in Cyberpunk 2077 are cyborgs, but in this case, I'm referring to one voice actor posing as another using voice-cloning technology, following the second actor's death.
