Verdict Delivered in miHoYo's Genshin Impact AI Voice Impersonation Case, Awarding 750,000 RMB in Compensation

According to TechFlow, on September 10, reports from IT Home indicated that the Shanghai Pudong New Area People's Court recently handed down a verdict in Shanghai's first unfair competition dispute case involving AI voice forgery. In 2025, miHoYo discovered an unauthorized AI voice-changing application that used sound packs for 63 characters from Genshin Impact, allowing users to pay for voice alteration. It also trained its AI voice-changing model using merely one minute of character audio blended with other materials. Forensic voiceprint analysis determined that the altered vocal effects were "highly likely to be deemed identical" to the original in-game character voices. The court ultimately ruled that the defendant must immediately cease the infringing conduct and compensate miHoYo 750,000 yuan. Additionally, on September 7, the Supreme People's Court released its first judicial rulebook concerning AI, explicitly clarifying that using an individual's voice without consent to train AI models constitutes infringement, ensuring that AI "voice theft" is no longer relegated to a legal gray area.
