CD Projekt Red used AI to alter the voice of Geralt's original Polish actor in Witcher 3: Songs of the Past

For The Witcher 3's Songs of the Past expansion, CD Projekt Red used AI to alter the voice of Geralt's original Polish actor, Jacek Rozenek. In 2019, Rozenek suffered a stroke that left him unable to speak. In an interview with Game File , he described his recovery, which required six to seven hours of voice training daily. Rozenek briefly returned to voice Geralt in The Witcher 3's 2022 next-gen update but found the sessions exhausting. CDPR wanted him back for Songs of the Past but recognised his voice now differs significantly from 12 years ago.
