Complete Voice Security Platform
Resemblyzer
Next-generation voice biometrics powered by a 1 billion parameter deep learning model. Passive identification and verification with text-independent, language-agnostic speaker recognition.
DETECT-3B Omni
The industry’s first enterprise-grade multimodal deepfake detection system. 3 billion parameters trained on thousands of generative models to detect synthetic audio, image, and video.
Resemble Intelligence
Explainable AI that provides natural language forensic reports. Goes beyond binary classification to explain exactly why content was flagged, with deep contextual analysis for disinformation defense.
Neural Watermarking
Embed imperceptible, encrypted watermarks into AI-generated audio. Distinguish between authorized AI (your agents) and unauthorized AI (fraudsters). Survives compression and resampling.
Resemble AI is Built for the Generative AI Era
Gen AI Deepfake Detection
Our DETECT-3B Omni model identifies synthetic content from 1,320+ generative AI models including ElevenLabs, OpenAI, Pika, and Runway. 95% accuracy, 6x faster than realtime.
3-Second Enrollment
Using few-shot learning, users can enroll with just 3 seconds of speech. No scripted phrases, no repetition required. Drastically reduces friction and abandonment.
Language Agnostic
Our 1 billion parameter Resemblyzer model is trained on massive multilingual datasets. A speaker’s identity vector remains consistent across Japanese, English, Spanish, and 40+ languages.
Explainable AI with Intelligence
Resemble Intelligence provides natural language forensic reports explaining why content was flagged. Essential for regulatory audits and dispute resolution in financial services.
Privacy by Design
Audio is processed in RAM/VRAM only—never stored to disk. Streaming protocol enables continuous analysis without creating persistent copies. Full data sovereignty.
On-Premise & Air-Gapped
Deploy behind your firewall with complete data sovereignty. Docker/Kubernetes native, no external dependencies. Meets the strictest compliance requirements globally.
