The Witcher 3 Uses Generative AI to Work on Geralt's Polish Voice

CD Projekt Red has confirmed that it used generative AI on the voice of the Polish actor who plays Geralt of Rivia in The Witcher 3, and that the tool is still in use as the studio prepares the Songs of the Past expansion. According to the studio, the technology is being used to treat the actor's voice and to alter it, which is a notable admission given how closely that Polish performance is tied to the character for many fans.

The disclosure comes at a sensitive moment for AI in games. Voice work has become one of the most contested areas of the technology, with performers and their unions pushing for clear consent, fair pay, and limits on how their voices can be reproduced or modified. Any studio that uses AI on a recognizable performance is now expected to explain exactly what it did and why, and this case is no exception.

The studio's defense, as quoted in the coverage, is that this is one of the ways AI can be used ethically. That argument leans heavily on the context, since the tool is being applied to a performer's own voice rather than to replace a performer outright. Whether that framing settles the debate will depend on details that have not been fully laid out, including whether the actor agreed to the process, how much of the final audio is generated, and what safeguards govern future use.

For players, the practical question is simple: will the Polish Geralt in Songs of the Past sound like the character they know? For the industry, the bigger question is whether this kind of case becomes a template or a warning. Either way, expect the conversation around AI in games to move past whether studios use these tools and toward how they disclose them and who gets a say.
