CD Projekt uses voice AI to match Geralt's Polish lines to 2015 recordings
Jacek Rozenek still performs every new line in Songs of the Past; software trained on his older work narrows the gap left by his 2019 stroke.
Key takeaways
- CD Projekt Red is using AI voice processing on Geralt's Polish dialogue in The Witcher 3 expansion Songs of the Past.
- Jacek Rozenek, the Polish voice of Geralt since the first game, records all new lines himself.
- Rozenek had a stroke in 2019 and was unable to speak for months before returning to the role.
- The studio says his voice is now lower and rougher than in the 2015 recordings.
- Songs of the Past is scheduled to launch in 2027.
What the studio is doing
CD Projekt Red has confirmed that AI voice software is being applied to Geralt's Polish dialogue in Songs of the Past, the upcoming expansion for The Witcher 3. The technology does not write or perform the lines. It processes recordings made by Jacek Rozenek, who has voiced the character in Polish since the first Witcher game, so that they sit closer to how he sounded in the 2015 release.
The studio worked with Respeecher, a voice-technology company it had already used on Phantom Liberty, the Cyberpunk 2077 expansion. An algorithm trained on Rozenek's earlier performances adjusts the new recordings. According to the account published by Game File, the actor's acting and delivery remain his own; the software only narrows the difference in timbre.
Why the voice changed
Rozenek had a stroke in 2019 and could not speak for several months. He trained his voice for six or seven hours a day during recovery and eventually came back to the part, recording extra lines for The Witcher 3's next-gen update in 2022. He told Game File that those sessions left him exhausted.
When CD Projekt brought him back for Songs of the Past, the studio found his voice noticeably lower and rougher than in the original game. The expansion is set around the same period as the base game, so a sudden change between old and new dialogue would be audible to players.
Rozenek described the goal in his own words: «The point is that this voice should be as close as possible to my voice from 12 years ago.» He gave his consent to the process and said he trusts the developers.
The studio's framing
Mikołaj Szwed, a localization producer at CD Projekt, said he understands the wider concern about AI in games but described this case as a special one, made necessary by the actor's health. The studio's stated aim was to keep Rozenek in the role rather than replace him or generate his performance from scratch.
Songs of the Past is scheduled to launch in 2027. CD Projekt has not said whether the same processing will be used for Geralt's voice in other languages.
