What is Resemble.ai?
Resemble AI is an enterprise-grade AI voice platform that generates, verifies, and detects synthetic media across voice, image, and video for complete generative AI security. The platform offers production-grade text-to-speech with zero-shot voice cloning through its open-source Chatterbox model, which outperforms competitors like ElevenLabs in blind A/B testing. Users can clone a voice from as little as 10 seconds of audio, with every output automatically watermarked using PerTh technology for provenance tracking.
Key features include multimodal deepfake detection (audio, image, video) with 98.1% accuracy using the DETECT-3B Omni model, real-time speech-to-speech conversion with emotion control, audio watermarking that survives compression and editing, and on-premises deployment for air-gapped environments. The platform provides full API access with Python and Node.js SDKs, supports 149+ languages for localization, and includes rapid and professional voice cloning options. Resemble AI also offers deepfake detection via a Chrome extension and integrates with platforms like TikTok, Unity, Roblox, and Twitch.
Resemble AI is designed for Fortune 500 companies, government agencies, developers, content creators, and enterprises prioritizing safety and security. It serves use cases including customer service voice agents, outbound sales, healthcare triage, entertainment, podcasting, game development, and brand protection against deepfake fraud. The platform is EU AI Act ready with enforcement coming in August 2026.

Frequently asked questions about Resemble.ai
Is Resemble AI free to use?
Yes. You can try the playground without an account. Sign up for a free account to run the tools on your own files with no credit card required. The open-source models Chatterbox, PerTh, and Resemblyzer are completely free with no usage limits or rate caps—you can run them wherever you want, including on-premises.
How does AI voice cloning work?
Upload as little as 10 seconds of audio and Chatterbox generates new speech matching the original voice. Every output has a PerTh watermark embedded upon request. The system uses zero-shot voice cloning, meaning it can clone a voice without prior training on that specific speaker.
Can deepfake detection run on-premises?
Yes. DETECT-3B Omni runs entirely on your infrastructure with no data leaving your network, no telemetry, and no external dependencies, including air-gapped environments. It detects AI-generated audio, video, and images from a single model. This is ideal for organizations with strict data sovereignty or compliance requirements, including EU AI Act readiness ahead of August 2026 enforcement.
What is audio watermarking?
Audio watermarking embeds an imperceptible signal in a file that survives compression, editing, and re-encoding. Resemble's PerTh watermarker achieves approximately 95-100% detection accuracy post-manipulation using psychoacoustic masking. The watermark is permanent, indestructible, and invisible, embedded at generation time before the audio leaves your infrastructure.
What types of voice agents does Resemble support?
Resemble provides voice generation, watermarking, and detection components that integrate into any agent architecture—including customer service, outbound sales, healthcare triage, or agent-to-agent pipelines. The platform supports both text-to-speech and real-time speech-to-speech for interactive voice agents.
How accurate is Resemble's deepfake detection?
Resemble DETECT-3B Omni achieves 98.1% overall detection accuracy across WAV, FLAC, MP3, WEBM, M4A, and OGG formats, outperforming competitors like Aurigin AI (96.8%), Hive AI (83.5%), and Reality Defender (71.3%). The platform is battle-tested against 160+ generative AI models and provides zero-day support for new models as they release.
What languages does Resemble AI support?
Trial, Personal, and Creator tiers include Spanish (MX), French, and British English. The Professional plan offers 68 languages for Localize, and the Business plan provides 148-149+ languages for full localization capabilities across synthetic voice generation.
Does Resemble AI offer an API?
Yes, Resemble AI provides full API access with official client libraries for Python (for scripts, notebooks, back-end) and Node.js (TypeScript-first with streaming helpers). REST API is available for any other language. The API supports text-to-speech, speech-to-speech, voice cloning, watermarking, and deepfake detection with synchronous and asynchronous processing options.
What is Chatterbox?
Chatterbox is Resemble AI's leading open-source Voice AI model with 24K+ GitHub stars and 10M+ Hugging Face downloads. It provides production-grade text-to-speech with zero-shot voice cloning, outperforming ElevenLabs in blind A/B testing (65.3% preference vs 24.5%). It's the first open-source model with emotion exaggeration control, achieves sub-200ms voice cloning, and automatically embeds PerTh watermarks in every output under MIT open-source license.
Is Resemble AI compliant with the EU AI Act?
Yes, Resemble AI is EU AI Act ready with enforcement coming in August 2026. The platform's on-premises deployment option supports strict data sovereignty requirements, with no data leaving your network, no telemetry, and air-gapped deployment capabilities. The watermarking and detection features help organizations meet provenance and transparency requirements for synthetic media.
