CD Projekt Red has used AI to restore the Polish voice of Geralt for The Witcher 3: Songs of the Past, according to TechPowerUp. Jacek Rozenek is returning to the role, with the report describing voice-matching technology intended to bring his new recordings into line with Geralt’s 2015 sound.
Rozenek has voiced Geralt in Polish since the first Witcher game, giving that vocal continuity a history stretching beyond The Witcher 3. The report also relays CD Projekt Red’s statement to Game File that it worked with a Ukrainian AI company. That developer statement establishes the collaboration; the more detailed account of how the dialogue was produced comes from commenter DrUsmanSaleem.
According to DrUsmanSaleem’s account, cited by TechPowerUp, Rozenek performed every new line himself. That attribution matters: the described process starts with fresh performances from the returning actor, rather than treating his involvement and the use of AI as mutually exclusive. On that account, the technology’s role was to alter the sound of recorded dialogue — not to dispense with recording the actor.
The commenter identifies Respeecher’s model as the tool involved, saying it was trained on Rozenek’s original Witcher 3 recordings and then used to reshape the newly recorded takes to match Geralt’s 2015 voice. The meaningful distinction is between the performance and its vocal treatment: Rozenek supplied the new dialogue, while the model used his earlier work as the reference for how those takes should sound. For the Polish version of Songs of the Past, the reported approach pairs the returning performer with a voice-matching process built around his own recordings.
