CD Projekt Red Uses AI to Restore Geralt's Polish Voice After Actor's Stroke
Jacek Rozenek returns to voice Geralt but AI helps match his lines to the original game.
CD Projekt Red has partnered with AI voice company Respeecher for The Witcher 3 expansion Songs of the Past, set for release next year. The Polish voiceover for Geralt will be adjusted using AI to match the actor's performance from the base game.
Jacek Rozenek, the original Polish voice actor for Geralt, has returned to record all new dialogue for the expansion. However, Rozenek suffered a stroke in 2019 that affected his speech. After daily training, he returned to voice acting in 2022 for a new quest in the PS5 version of The Witcher 3, a process he described as exhausting.
For Songs of the Past, CD Projekt Red recorded Rozenek's lines as usual. The studio then sent the recordings to Respeecher, which uses AI tools trained on Rozenek's earlier work to make the new lines sound like the Geralt from 12 years ago. Rozenek has given his blessing to the process, stating that the voice should be as close as possible to his original performance.
This AI adjustment only applies to the Polish language option. English voice actor Doug Cockle has returned to voice Geralt for the English version without any AI processing.
