## Key points

- CD Projekt will use AI to adjust Rozenek’s Polish Geralt lines.
- Rozenek reportedly consented, seeking a closer match to his earlier voice.
- The studio says this is a special case for the expansion.

## Summary

CD Projekt Red has confirmed plans to use generative AI to adjust Jacek Rozenek’s newly recorded Polish lines as Geralt in the upcoming The Witcher 3: Songs of the Past expansion. The studio says the change, made with Rozenek’s consent, will make his voice sound closer to recordings from before a 2019 stroke; it has chosen to keep him in the role rather than recast him.

Rozenek returned to record some lines for the 2022 update, but the work reportedly left him exhausted, and his voice has since become lower and gruffer. He said he trusted the game’s creators and wanted the new voice to resemble his voice from 12 years ago. CD Projekt describes the AI use as a special case: Doug Cockle’s English lines will not be altered, nor will Rozenek’s lines in future Witcher games. The decision renews debate over consent, actors’ work and when voice synthesis is appropriate.
