[miHoYo's 'Genshin Impact' AI Voice Imitation Case Verdict: Awarded 750,000 Yuan in Compensation] Deep Tide TechFlow reports that on September 10, according to IT Home, the People's Court of Pudong New Area, Shanghai, recently ruled on Shanghai's first unfair competition dispute case involving AI voice imitation. In 2025, miHoYo discovered an AI voice-changing software that, without authorization, used voice resource packs of 63 characters from 'Genshin Impact' to provide paid voice-changing services to users. The software trained its AI voice-changing model by mixing just one minute of character audio with other materials. Forensic voiceprint analysis determined that the voice-changing effect was 'inclined to be identified as identical' to the original voices of the game characters. The court ultimately ordered the defendant to immediately cease the infringing activities and awarded miHoYo 750,000 yuan in compensation. Additionally, on September 7, the Supreme People's Court issued the first judicial ruling guidelines related to AI, clarifying that using a natural person's voice to train AI models without their consent constitutes an infringement. AI 'voice theft' is no longer in a legal gray area.
