CD Projekt used AI to modify the voice of Geralt's Polish actor after a stroke left it significantly changed: 'This was a special case'
Jacek Rozenek was the voice of Geralt in all previous Polish-language Witcher releases, and CD Projekt wanted to work with him again—but his voice is no longer a match.
CD Projekt used AI to modify the voice of Polish actor Jacek Rozenek, who voiced Geralt in The Witcher 3, after a stroke left his voice significantly different. Rozenek suffered a stroke in 2019, which left him temporarily unable to speak and took time to recover. When CD Projekt decided to make a new Witcher 3 expansion, they wanted Rozenek back for the role, but his changed voice presented a problem.
