The voice talent behind Cyberpunk 2077 is looking quite extensive. Reportedly, more than 150 Chinese voice actors are attached to dub the Mandarin voice lines, of which there are more than 100,000. All of this work is being performed in four different recording studios. Clearly, this suggests the amount of English voice talent will prove just as robust.
Such effort eclipses that of The Witcher 3: Wild Hunt by a wide margin. According to Niko Partners Senior Analyst Daniel Ahmad, the voice work for Chinese localization in Cyberpunk 2077 is about 15 to 20 percent more than that of what was present in The Witcher 3 and its DLC offerings. Ahmad noted all of the above in the following Twitter post:
