After a meeting between the two sides confirmed that Rozenek's voice had grown lower and gruffer due to some combination of the stroke and him simply getting older, the studio made the decision not to recast the actor, but instead let modify Respeecher modify his lines to make them sound closer to those original recordings. Rozenek reportedly gave his blessing for this to go ahead. "The point is that this voice should be as close as possible to my voice from 12 years ago," he told Game File. "I have great trust...for the creators of this game."
This isn't the first time CD Projekt Red have enlisted Respeecher's services. Back in 2023, it was revealed that the studio had used speech synthesis software to make ripperdoc Viktor Vektor's lines in the Polish version of Cyberpunk 2077's Phantom Liberty expansion sound like actor Miłogost Reczek. Reczek died in 2021 before he could reprise his role as Vektor for the DLC, so rather than recasting the character across the whole game to avoid noticeable differences in voice, CD Projekt got another actor to voice Vektor's new lines for Phantom Liberty, then used the genAI tech to make those lines sound like Reczek was delivering them. CD Projekt Red said at the time that they'd gotten permission from Reczek's family before going ahead with their plan.
