A professional voice actor sued a São Paulo shopping centre, saying it used the actor's voice without authorisation in a marketing campaign shown on YouTube, and claimed lost earnings and moral damages. The centre answered that the voice was not the actor's but a synthetic voice produced with Microsoft's text-to-speech service, available to the public. According to the legal news site ConJur, a judge of the 18th Civil Court accepted that the voice was produced synthetically and dismissed the claim; on appeal the actor argued that a notarised record attesting to the similarity of the voices had never been assessed. The 6th Private Law Chamber of the São Paulo Court of Justice annulled that judgment for curtailment of the defence, holding that the use of AI does not by itself rule out misuse of third parties' rights, and sent the case back for evidence on how the campaign voice was generated and how similar it is to the actor's. The court docket shows the case back at first instance at the court-expert stage in 2025; no ruling on the merits is reported. Whether the AI voice reproduces the actor's voice is disputed.

Remie Michelle Clarke, a voiceover artist in Dublin, told Bloomberg Law in April 2023 and Marketplace in June 2023 that a synthetic voice built from recordings she had made for Microsoft's text-to-speech software was being sold by a third-party AI voice company, Revoicer, as a voice called Olivia that customers could make say anything. She said she learned of it when a fellow actor asked whether another voice job had paid her well, that she had since found a number of adverts and a couple of tech products using her voice, and that buyers choosing the AI voice was affecting her smaller jobs. She said she was completely shocked. Microsoft told Marketplace that it informs voice talent and obtains their legal consent to create synthetic voices; it did not address the resale. No response from Revoicer and no legal action are reported in the inspected sources.

Greg Marston, a British voice actor, said in accounts published in 2023 that an AI-generated clone of his voice, built from a recording he had made for IBM years earlier, was being sold to websites that were using it to build a synthetic voice that could say anything. Julia Angwin's New York Times column (republished by the Oman Observer on 25 September 2023) says he found the clone, called Connor, online and heard his voice on the Wimbledon website during the tennis tournament; Cryptopolitan (1 July 2023) says he found it on Revoicer, an AI text-to-speech site. He had signed a release allowing the recording to be used in many ways, but said he never agreed to having his voice cloned to compete against him. He estimated that the clone had already lost him jobs and was working with a lawyer to seek compensation. IBM said it was aware of his concern and was discussing it with him. The outcome is not reported in the inspected sources.

Claudio Serrano, the Spanish dubbing actor who is the Spanish-language voice of Batman and Ant-Man, said in a TikTok video posted on 11 September 2026 that a US-based artificial intelligence platform, which he did not name, has a profile carrying his name, his image and an excerpt of a clone of his voice presenting itself, made and offered without his permission. Computer Hoy and Infobae relayed the video on 12 October 2026. Serrano said that when he tried to complain, the platform asked him to pass a voice captcha to prove he is the real Serrano, and that his lawyers are working on the matter. The platform's account of the voice, its name and any response are unknown.

Event date unknownMexicoUnidentified voice-cloning tool (suspected)
On 25 September 2026 Diego Carreto, a 26-year-old commercial announcer from León, Guanajuato, published a video saying that a promotional spot for Vendimias Guanajuato 2026, produced by a private agency and distributed by the state Secretaría de Turismo e Identidad, used his voice although he never recorded it, never worked with the agency and was never contacted. He showed segments of the spot and repeated the same lines himself. He believes his public voice demo was fed into a generative-AI system, and asked for removal of all material with his voice, payment for its use, legal action against those responsible and deletion of his biometric data. He says the spot ran nationally, and within Guanajuato on radio, on state government social media and on the Visit México platform. The secretariat said it rejects any unauthorised use of a person's voice or image, including with AI tools, and asked the producing company to clarify what happened. AI use has not been confirmed.
