Voice Actor Sues TikTok Over AI Baritone Imposter

A prominent Japanese voice actor, Kenjiro Tsuda, has initiated legal action against TikTok, seeking the removal of videos that he claims feature an AI-generated clone of his unique baritone voice. This lawsuit, filed by Tsuda known for major franchises like "Jujutsu Kaisen," is considered the first in Japan to defend an individual's vocal identity against AI impersonation. The platform, however, contends that the voice in question is a generic male tone and its similarity to Tsuda's is subjective.

The case highlights growing concerns within the global performing arts industry regarding AI imitation, particularly impacting Japan's renowned animation sector. Tsuda's legal team asserts that the unauthorized use of his voice infringes upon his publicity rights, as the anonymous account reportedly earned significant revenue by narrating urban legends and conspiracy theories. While the account is no longer active, the Tokyo District Court's ruling on Wednesday will address TikTok's responsibility for hosting such content.

Parallel to the lawsuit, Japanese voice actors have launched a campaign, "No More," advocating against the unconsented use of generative AI to mimic performers. Experts and fellow actors express solidarity, emphasizing the potential for AI voice cloning to undermine the industry and discourage aspiring artists. The International Federation of Actors has noted that existing copyright and data protection laws are struggling to keep pace with AI advancements globally.

While Japan has recently issued non-binding guidelines protecting voices under publicity and likeness rights, their influence on Wednesday's verdict remains uncertain. TikTok has challenged Tsuda's claim of national fame and argued its role as a platform for user-generated content, protected by free speech principles. The international interest in this case is significant, with predictions that the outcome could set a precedent for vocal identity protection worldwide.
