The Witcher 3 AI voice decision is now confirmed: CD Projekt Red's Songs of the Past expansion will use Respeecher to adjust Geralt's Polish lines. The studio says it did so with the full consent of actor Jacek Rozenek, who suffered a stroke.

The story broke on the evening of November 11 in Game File's interview with CD Projekt and Respeecher. Songs of the Past will be Geralt's last adventure after the Remastered release in September, which picked up a prize at the Golden Joystick Awards 2026.

How does the Witcher 3 AI voice work?

Jacek Rozenek has voiced Geralt in every Polish Witcher release. In 2019 a stroke left him unable to speak for a while. He got his voice back through intensive training.

He returned for a couple of quests in the 2022 next-gen update, but told Game File he "was so exhausted after this recording". For the new expansion, his voice sounded clearly lower and gruffer than it did a decade ago.

So CD Projekt Red turned to Respeecher. PC Gamer's write-up of the Game File report explains that Rozenek still records every new line himself. Respeecher then shifts those takes toward his original sound, using a model trained on his old Witcher 3 lines.

Respeecher's Dmytro Vasylets said it took dozens of hours. The hardest part was Rozenek's emotional range: shouts, groans, fear and laughter, plus AI artifacts that "never fully disappear".

Why does CD Projekt Red call it a special case?

Localisation producer Mikołaj Szwed admitted that AI is a big concern for voice actors around the world. Still, he sees this as an ethical use with consent, and stressed it only came up because of Rozenek's health.

According to IGN's report, the studio will not alter an actor's voice without explicit permission. It also won't be needed for The Witcher 4, since an older Geralt can plausibly sound deeper.

This is not the studio's first project with Respeecher. For Cyberpunk 2077: Phantom Liberty, it recreated the voice of Polish actor Miłogost Reczek, who died in 2021, with his family's blessing. Cyberpunk is also in the news this week with Cyberpunk 2077 launching on Battle.net.

What does it mean for players?

Nothing changes if you play in English. Only players who pick the Polish voice track are affected, and they will hear a Geralt closer to his 2015 tone.

Even so, the move will spark debate. AI remains a touchy subject across the industry, from voice work to storefronts, as seen in Valve's response to Steam's AI slop problem.

Songs of the Past takes Geralt to Letten, a new region, and is co-developed with Fool's Theory. After that, Ciri takes the lead. For more on what comes next, read everything we know about The Witcher 4.

Frequently asked questions

Why is AI used in The Witcher 3: Songs of the Past?

Jacek Rozenek, Geralt's Polish voice actor, suffered a stroke in 2019 that changed his voice. With his consent, CD Projekt Red used Respeecher so his new lines match his original Witcher 3 performance.

Will Geralt's English voice be changed with AI?

No. CD Projekt Red localisation producer Mikołaj Szwed said there are no plans to do the same with Doug Cockle, who voices Geralt in English. It only applies to the Polish dub.
