Tokyo court says a performer's voice can carry publicity rights, but dismisses TikTok deletion claim

A Tokyo court said unauthorized exploitation of a commercially attractive voice can infringe publicity rights. It dismissed Kenjiro Tsuda's TikTok deletion claims after the posts were removed, without deciding whether the clips infringed.

The big change

The court said a person's voice can symbolize identity like a likeness. Unauthorized use of a performer's voice can infringe publicity rights when the voice attracts customers and the use is solely aimed at exploiting that appeal. The judges did not decide whether these clips met that test.

Performers challenging commercial voice imitation can now cite that judicial statement, but they still need evidence tying a disputed voice and its use to the claim. Tsuda's deletion request ended after the posts were removed, leaving similarity, infringement and TikTok's responsibility for the posts unresolved.

OpenAI’s Decisions API: what developers can verify today

OpenAI announced a finite-choice Decisions API in limited preview. Its recap describes classification and routing, while public integration details remain unpublished.

The big change

OpenAI has announced a service expressly framed around finite, developer-defined decisions from text or images. The immediate opportunity is a clearer boundary between a model’s answer and the application that uses it. For now, that is a product description at limited-preview stage. The missing public contract prevents a reliable implementation guide or a measured comparison with existing APIs.

Our DevDay launch guide places Decisions API among the event’s releases and previews. This follow-up concentrates on the decision interface and what a developer can verify. BIG CHANGE’s Jev overview and Jev demonstrations cover TypeSafe AI’s separate product. Similar decision-oriented language is no evidence of shared architecture, training or API behavior.
