CD Projekt RED confirms use of genAI for Geralt’s Polish lines in Songs of the Past expansion

CDPR wanted original VA Jacek Rozenek back, but a stroke he suffered in 2019 led the studio to use genAI to enhance his new lines with his blessing.

CD Projekt RED is using generative AI to enhance the voice lines of Geralt of Rivia’s Polish voice actor, Jacek Rozenek, in the upcoming The Witcher 3: Songs of the Past expansion.

CDPR confirmed this detail in a recent interview with Game File where it defended its decision, claiming it was a last resort to keep Rozenek in the iconic role. Rozenek suffered a stroke in 2019 which affected his ability to act. He has had voice training since and returned to acting, but his voice was reportedly deeper and older. CDPR wanted him to sound more like his original recordings for The Witcher 3, and feared his changed voice would sound like a mismatch, so the team called in an AI company it has used before on the likes of projects like Cyberpunk 2077.

For his part, Rozenek gave his blessing and signed off on the use of generative AI enhancement to get his new voice lines closer to the old ones. Reportedly, the casting of a soundalike was also dismissed as CDPR was invested in Rozenek’s voice.

“The point is that this voice should be as close as possible to my voice from 12 years ago," Rozenek explained. "I have great trust ... for the creators of this game.”

The Witcher 3: Songs of the Past is set for a 2027 launch, following a major free update of the base game and its DLCs. As we await further details, stay tuned to The Witcher series topic for updates.
