The Witcher 3: Songs of the Past’s Polish Geralt VA will be tuned with AI due to the actor’s health concerns

CD Projekt Red is using AI to adjust Polish Geralt actor Jacek Rozenek’s voice for the upcoming Witcher 3 expansion, Songs of the Past. Rozenek, who suffered a stroke in 2019, is recording the new lines himself, with his approval; the technology is intended to make his voice sound more like his earlier performances.

Rozenek recovered some speech and recorded lines for the game’s next-generation update in 2021, but the work left him exhausted. For the expansion, the studio found his voice had become rougher and lower, and turned to Ukrainian company Respeecher to tune it for new combat and other scenes. The article raises concerns that doing so could set expectations that voice actors’ voices should not change over time.
