CDPR has used Respeecher AI technology to restore the early Polish voice line of Geralt in 'The Witcher 3'.

CDPR has adopted Respeecher AI technology to provide Polish voice acting for the new DLC of 'The Witcher 3: Wild Hunt', adjusting the hoarse voice of Jacek Rozenek after a stroke to an early effect. Rozenek personally recorded new lines, and Respeecher used its early voice model for conversion, focusing on restoring his emotional expression. CDPR stated that they may no longer use this method in the future, and that Rozenek's current voice may be suitable for shaping an older Geralt.
