CD Projekt Red Uses AI to Restore Geralt's Polish Voice for Witcher 3 Expansion

CD Projekt Red has revealed that it used AI voice-processing technology to modify the performance of Jacek Rozenek, the Polish voice actor for Geralt of Rivia, in the upcoming Witcher 3 expansion "Songs of the Past." Rozenek, who voiced Geralt in every previous Polish-language Witcher release, suffered a stroke between the original game's launch and the new expansion, leaving his voice significantly changed. Rather than recast the iconic role, the studio partnered with an AI company to process Rozenek's newly recorded lines, restoring them to more closely resemble his pre-stroke delivery. Crucially, the process was carried out with the actor's full knowledge and consent.

CD Projekt Red has been open about why it considers this a justified and ethical use of AI technology. Studio representatives described it as "a special case," noting that the goal was never to replace the actor but to help him continue doing a job he had held for years, despite the physical challenges his health condition introduced. "This is one of those ways where you can use AI ethically," a developer told Kotaku, framing the decision as one rooted in respect for both the actor and the fans who have followed Rozenek's portrayal of Geralt across the entire series. The expansion arrives more than 11 years after The Witcher 3: Wild Hunt first released in 2015.
