CDPR Uses AI With Geralt Actor’s Consent for New Witcher 3 DLC

Jacek Rozenek says he trusts CDPR’s AI to match his Geralt recordings to his earlier voice after changes following his 2019 stroke.

CD Projekt Red is using AI to adjust the actor’s voice for the newly recorded, polished Geralt dialogue in The Witcher 3: Songs of the Past DLC. Rozenek is still performing the lines himself, but the studio is using Respeecher to match his voice to earlier recordings from before his 2019 stroke, so the old and new dialogue plays together more consistently for Polish audiences.

The English dialogue, performed by Doug Cockle, is not receiving the same treatment.

In a new interview with Stephen Totillo of Game File, CD Projekt Red Representatives explain how they use AI and a human-in-the-loop process to review every piece of dialogue.

When discussing concerns about using AI, CD Projekt’s localization producer Mikołaj Szwed noted that this is a big concern for the voice acting Community but also stated that he thinks “this is one of those ways where you can use AI ethically, with consent, and also to do something good.”

The actor also spoke about his trust in the team and their process.

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

CD Projekt Red recently released a remastered edition of The Witcher 3, which broke the game’s all-time player record on Steam upon release. For more on songs of the past, check out our preview while you wait for the new DLC to drop in 2027.
