It has been revealed that CD Projekt Red used AI to recreate the voice of an actor who passed away shortly after the release of Cyberpunk 2077 in its Phantom Liberty expansion.

The details:

  • As reported by Bloomberg, the studio used AI technology to recreate the voice of Miłogost Reczek, a Polish actor who played Viktor Vektor in Cyberpunk's Polish-language version. Reczek died in 2021, but CD Projekt wished to use his character in the then-upcoming expansion.
  • Originally, the developer considered not only replacing the deceased voice actor in the DLC content but also replacing the existing lines in the base game for consistency. The studio "didn't like this approach," according to CD Projekt localization director Mikołaj Szwed, because Reczek was not only "one of the best Polish voice talents," but his performance as the character was "stellar.”
  • Instead, CD Projekt hired a new voice actor to record the lines and then used software called "Respeecher" to alter the voice to make it sound exactly like Reczek had recorded them himself. The actor's family approved of the decision to use AI, with his sons said to be "very supportive" of the idea.
  • AI has remained an issue of debate across many mediums, with some claiming that AI-generated art should be avoided as it is trained using existing, human-created pieces, while others applaud its convenience. Although situations such as Viktor Vektor's inclusion in Cyberpunk benefit greatly from AI-assisted voice alteration, it has also been used to create terrifyingly accurate recreations of celebrities such as Drake.
