CD Projekt Red Uses AI to Modify Geralt's Polish Voice Lines for Witcher 3 Expansion

What changed#

CD Projekt Red has reportedly engaged Ukrainian artificial intelligence firm Respeecher to modify audio recordings for Geralt of Rivia in the Polish-language version of The Witcher 3: Wild Hunt. This specialized audio processing is being carried out for the game’s upcoming expansion, titled Songs of the Past.

The technical modifications center on dialogue recorded by Jacek Rozenek, the longtime Polish voice actor for Geralt. After Rozenek suffered a stroke that altered his vocal delivery, CD Projekt Red sought a method to adjust his newly recorded audio. With Rozenek’s explicit permission, the studio partnered with Respeecher to apply generative AI technology to his performance. The goal of this process is to alter the newly recorded dialogue so that Geralt’s voice in Songs of the Past sounds similar to the lines Rozenek delivered for the original game before his stroke occurred.

Why it matters#

The decision to utilize generative AI in this manner allows CD Projekt Red to maintain vocal continuity for Geralt in Polish while continuing to work directly with Jacek Rozenek. Instead of recasting the role or leaving the modified vocal delivery unadjusted, the studio chose to process Rozenek’s actual performances using Respeecher’s tools.

Key details regarding this audio update include:

• Actor Permission: Jacek Rozenek granted consent to CD Projekt Red and Respeecher to alter his recorded performances using AI tools.
• Vocal Consistency: The AI adjustments are designed to match the tone of the new Songs of the Past lines with Rozenek’s pre-stroke work on the original game.
• Targeted Application: The generative AI work applies specifically to the Polish-language voice track for Geralt of Rivia in the upcoming expansion.

What to do next#

Players who experience The Witcher 3: Wild Hunt using the Polish audio track can expect Geralt’s dialogue in the Songs of the Past expansion to feature these AI-assisted recordings from Jacek Rozenek. Players should follow official announcements from CD Projekt Red for further details on the expansion’s release schedule and technical implementation.
