AI voice company ElevenLabs Japan has announced a significant step toward ethical AI and content authenticity with its latest security framework, which combines its proprietary VoiceCAPTCHA technology with the C2PA international standard.
This new dual-layer protection aims to ensure the traceability and reliability of AI-generated voices, while safeguarding Japan’s voice actor industry and creative culture from unauthorized voice cloning and deepfake misuse.
ElevenLabs has been a frontrunner in the global AI audio field, with its tools already used by creators, developers, and studios worldwide. Building upon its existing advanced safety measures, the company is now officially adopting C2PA (Coalition for Content Provenance and Authenticity), an international framework supported by Adobe, Microsoft, and Google, to further enhance trust and transparency in AI-generated content.
C2PA enables every piece of digital content to include tamper-proof metadata showing its creation and editing history, allowing users to verify whether an audio file was generated by AI and trace its origin.

Combining VoiceCAPTCHA and C2PA
Before this update, ElevenLabs already employed three major safety systems:
- VoiceCAPTCHA: a strict identity verification process that ensures voice cloning can only be done by the actual speaker, using live voice-matching.
- AI Speech Classifier: a detection tool that embeds inaudible digital watermarks into every audio clip created through ElevenLabs.
- Traceability System: a mechanism to identify the origin of any misused audio and coordinate with relevant authorities.
With the new C2PA integration, these proprietary systems now gain an international verification layer, creating a dual framework of prevention and traceability, setting what the company calls a “world-leading standard in AI audio safety.”
Supporting Japan’s Voice Actor Culture
ElevenLabs emphasized its deep respect for Japan’s unique voice acting and anime culture, stating its clear opposition to unauthorized AI-generated voices using celebrity or seiyuu data.
The company voiced its support for Japan’s “NO MORE Unauthorized AI Generation” movement and reaffirmed its commitment to helping Japanese creators and studios adopt AI responsibly, not as a threat, but as a tool that can coexist with human artistry.
Renowned voice actor Yuki Kaji (known for Attack on Titan’s Eren Yeager) also praised the initiative, calling VoiceCAPTCHA x C2PA “a long-awaited system that truly protects the rights of our voices.”
“AI isn’t the enemy — it’s a tool. Whether it becomes a partner or a problem depends on how we use it,” Kaji said. “This technology marks a turning point in AI’s history and could finally allow creators and AI to coexist safely.”
ElevenLabs CEO Mati Staniszewski has commented, “Japan’s voice acting culture is among the richest in the world. For us, innovation must go hand in hand with trust and ethics. By aligning with the C2PA standard, we’re reinforcing our commitment to protecting Japanese creators while building a transparent, safe environment for AI audio.“
Implementation and Future Plans
C2PA integration rollout will begin in November 2025. All audio generated through ElevenLabs will include Content Credentials (tamper-proof metadata) verifying its origin and preventing malicious alteration.
With a valuation of nearly $6.6 billion (approx. ¥1 trillion) and over 40 million users, ElevenLabs is now positioning itself as not just an AI leader, but as a responsible partner to the global entertainment industry, from Hollywood studios to anime production houses.
