CD Projekt Red Used AI to Alter Geralt's Voice Due to Polish Actor's Health Issues

CD Projekt Red is employing an AI tool to modify Geralt’s Polish voice for the upcoming Witcher 3 expansion after the original actor Jacek Rozenek suffered a stroke that altered his voice. The studio collaborated with Ukrainian AI firm Respeecher, preserving Rozenek’s performance while ensuring consistency across the game’s older map sections. The approach aims to keep the character’s authenticity despite health‑related vocal changes.
