CD Projekt used AI to modify Geralt's Polish voice
CD Projekt has used AI to modify the voice of Geralt's Polish actor, Jacek Rozenek, after a stroke left his voice significantly changed. Rozenek voiced Geralt in all previous Polish-language Witcher releases, and the studio wanted to work with him again, but his voice was no longer a match for the role. Rather than recasting, the team turned to AI, which the studio described as 'a special case.' For anyone working in games, localization or audio, this is a useful example of how AI tools are being applied to voice work where continuity and a performer's identity are at stake. It raises practical questions about consent, credit and how studios set boundaries when technology can reshape a human performance. Teams building voice pipelines should watch closely how this approach is received by players and performers alike.
