A single spoken phrase can now traverse languages while retaining its identity, generating both excitement and apprehension among performers. Behind the scenes, a quiet race is underway to safeguard the integrity of voices.
Artificial intelligence is creating new avenues for Japanese voice actors, while simultaneously enhancing the protection of their voices, a resource that is becoming increasingly significant in the global content marketplace. Emerging technologies not only facilitate the international reach of Japanese anime but also establish mechanisms for controlling how these performers’ voices are utilized.
In November, the Tokyo-based Voice Dubbing Development and Protection Association (VIDA) showcased its initiatives during a press briefing. Voice actress Mika Kanai demonstrated a brief phrase in Japanese that was then seamlessly translated into multiple languages, including English and Chinese, while maintaining its unique vocal qualities.
This cutting-edge technology, developed by the American firm ElevenLabs, specializes in AI-driven voice generation. It can convert speech into over 30 languages without compromising individual voice characteristics. Additionally, digital watermarks are embedded in the audio files, enabling usage tracking, ownership verification, and prevention of unauthorized duplications.
Market Expansion and New Opportunities for Actors
Founded with the collaboration of agencies and industry stakeholders, the VIDA association aims to leverage these technologies in partnership with rights holders to facilitate the global expansion of Japanese anime.
“Sales of Japanese anime have surged significantly overseas, and voice actors enjoy immense popularity. The number of fans will increase further if we can use the original actors’ voices instead of dubbed versions.”

At the same time, the trading corporation Itochu and the Japan Actors Union have announced the creation of the J-Vox-Pro voice database. This platform is designed to securely store, manage, and utilize the voices of performers both domestically and internationally.
Copyright and Income Challenges
This initiative arises amid escalating concerns over the ease with which modern technology can mimic human voices. Current Japanese law does not recognize a voice as a copyrightable object, allowing AI to learn from actors’ recordings and generate similar vocal renditions without legal repercussions.
There is already a proliferation of videos using AI-generated voices without performers’ consent, posing not only legal but also economic threats to actors. Many work as freelancers, often earning less than 3 million yen annually.
The J-Vox-Pro database seeks to establish a system through which actors can receive payment for the use of their voices, including AI-generated versions, in commercial undertakings.
New Applications and the Need for Legislation
Voice synthesis technologies have potential applications beyond the entertainment sector, such as enhancing in-car navigation systems or providing voice instructions for older individuals.
Meanwhile, the Japan Actors Union is contemplating additional strategies to combat unauthorized voice use, including seeking court injunctions and pursuing damages through lawsuits.
“Private-sector initiatives to certify original dubbing actors’ voices may help in curbing unauthorized usage. However, given the limitations, it is essential to push for legislative advancements to address this issue.”
– Kazuhiro Ando
Experts underline that without legal updates, comprehensive protection of performers’ rights will remain a challenge. However, the fusion of technological solutions and new legal frameworks may pave the way for a fair market, where actors’ voices are recognized not merely as artistic instruments but also as valuable, protected assets.
