Masako Nozawa condemns unauthorised AI use of performers’ voices

Masako Nozawa, the Japanese voice actor known for playing Goku, has condemned AI videos using performers’ voices without permission. The Japan Actors Union has also announced guidelines calling for consent and protections when voices are used in AI training or generated content, according to Dexerto.

What happened

Nozawa told Japanese broadcaster NHK that using her voice without permission was “unforgivable” and compared it to theft, Dexerto reports. The article says she was responding to AI-generated videos imitating her voice. It also says she supports AI’s potential while objecting to unauthorised use of performers’ work.

The Japan Actors Union’s guidelines, announced on 15 October, call for performers’ consent before their voices are used to train AI models, generate recordings or appear in published content. They also address compensation and protections against unauthorised use, the report says. Read Dexerto’s report.

Why it matters

Voice cloning can turn a recognisable performance into material for new content without the performer’s participation. The union’s guidance puts consent and compensation directly on the table, beyond the familiar debate over whether a synthetic voice sounds convincing.

The practical details matter: guidelines are not the same as a law or a guarantee that platforms will prevent unauthorised use. But they give performers and the industry a clearer set of expectations to argue over as AI voice tools spread.

Our read

A voice is not just a sound file with excellent branding. Nozawa’s objection, as reported, is about ownership and permission; the union’s guidelines make those questions more concrete. The next test is whether platforms, studios and AI developers build consent into how voices are collected and used, rather than treating it as a problem for performers to chase after publication.

What to watch

• Whether the union publishes the full guidelines and how members and employers apply them.
• Whether platforms or AI developers introduce clearer consent and compensation rules for voice use.
• Whether Japan’s wider policy debate turns these guidelines into enforceable protections.

Discussion spark: Should AI voice tools require a performer’s explicit permission and payment before using their voice, or should existing copyright and publicity rules be enough?
