CDPR confirmed that the new DLC for The Witcher 3: Wild Hunt, "Old Tunes"will use Respeecher technology to adjust Geralt's Polish voice lines. Actor Jacek Rozenek will still personally record the new dialogue; the technology will not replace his performance but will make the new recordings more closely match the voice he left behind before suffering a stroke in 2019, ensuring greater consistency between old and new dialogue.
Rozenek stated that the goal of this work is to make his voice sound as close as possible to how it was 12 years ago, expressing great trust in the game's creators and their approach. The entire process has been conducted with the actor's informed consent, and the production team has implemented a human review step to check each line of dialogue individually.
CDPR Localization Producer Mikołaj Szwed acknowledged that AI is a major concern within the voice acting community. He believes that using this technology is ethically acceptable when actors provide informed consent, remain involved in the performance, and the results undergo human review.
This adjustment applies only to the Polish performance. The English version of Geralt's dialogue, handled by Doug Cockle, will not receive the same treatment. The new DLC for The Witcher 3: Wild Hunt, "Old Tunes," is scheduled for release in 2027.
