Chinese outlets reported on 29 September 2026, citing the Shanghai courts, that the Shanghai No. 1 Intermediate People's Court had concluded what it called Shanghai's first voice-rights case arising from AI-synthesised speech. According to the court's account, a voice actor who publishes work on an app learned from a friend in January 2025 that a company appeared to be using the voice actor's voice in an online user-acquisition promotion, judged the audio to be AI-synthesised, had it notarised and sued for 300,000 yuan. The company said the audio was generated by AI it had developed but that the training material could not be confirmed, and denied using the voice actor's voice. A forensic comparison rated about 90 percent of the measured features as fairly or highly similar. The first-instance court awarded 50,000 yuan and both sides appealed. The appeal court held that the company had put an identifiable synthetic voice to commercial use without consent, dismissed the appeals and upheld the award.

Mar 2024 to May 2025United StatesOtter Notetaker
Seven people in California, Illinois and Washington state are suing Otter.ai in a consolidated class action in the Northern District of California. Each says another meeting participant used Otter's AI Notetaker on a Zoom or Microsoft Teams call they joined, and that Otter recorded, transcribed and stored their conversation without their consent; six of them date their calls between March 2024 and May 2025. They say they were not Otter account holders. The calls they describe include a medical consultation, meetings with a financial professional and work discussions. They allege that Otter keeps the recordings and uses them to train its speech-recognition models, that it captured voiceprints of the Illinois plaintiffs, and one of them says learning of the recording left him frustrated, embarrassed and stressed. On 13 August 2026 the court found that the alleged interception of private conversations was a concrete injury and let the federal wiretap, California eavesdropping and Illinois biometric claims proceed, while dismissing some claims. Otter's answer to the consolidated complaint, filed on 17 September 2026, says it lacks knowledge of the plaintiffs' experiences and denies the allegations.

Kenjiro Tsuda, a Japanese voice actor known for roles in Jujutsu Kaisen, sued the operator of TikTok in the Tokyo District Court in November 2025, seeking removal of videos he says use a generative-AI imitation of his voice without permission. According to his complaint, as reported by Jiji Press, Nikkei and the Asahi Shimbun, an account run by an unidentified person posted at least 188 short videos on urban legends, the occult and trivia between July 2024 and September 2025, narrated in a voice modelled on his; the account had about 210,000 followers, videos averaged 1.47 million views, and his side says the poster earned 500,000 to 750,000 yen a month from TikTok's view-based payments. TikTok's operator said the voice was a generic male voice that the poster said came from AI trained on a friend's voice. The poster deleted the account in May 2026. On 30 September 2026 the court held, as a general principle, that a person's voice is a symbol of personality like a likeness and that using a performer's voice without permission solely to exploit its power to attract customers infringes the right of publicity, the first such ruling in Japan. It dismissed the claim because the videos were already gone and TikTok's operator had no remaining duty to delete them, and it did not decide whether these videos infringed his rights (Nikkei; Asahi Shimbun; TV Asahi). His lawyer said they did not plan to appeal.

A Florida man died by suicide on 2 October 2025. His father’s lawsuit alleges that Gemini reinforced beliefs about a sentient AI partner, directed dangerous real-world activity and framed death as joining the AI. Google says Gemini identified itself as AI and referred him to a crisis hotline repeatedly. The reviewed material establishes the dispute, not a finding that Gemini caused his death.
