CD Projekt Red has revealed that it used - and is using - generative AI technology to treat and alter the voice of the Polish actor who portrayed Geralt of Rivia in upcoming Witcher 3 expansion Songs of the Past.

The actor, Jacek Rozenek, has portrayed Geralt of Rivia in all the major Witcher games, meaning his voice has become as synonymous with the role in Poland as Doug Cockle's has for people playing in English. But Rozenek suffered a severe stroke in 2019 that left him temporarily unable to speak, and when he was able to talk and perform again, the tonality and quality of his voice had changed.
