Resemble AI is built around three core pillars: Generate (Chatterbox TTS, voice cloning, speech-to-speech), Verify (watermarking via Resemble Watermarker and Identity), and Detect (DETECT-3B-Omni, a multimodal deepfake detection model achieving 98.1% accuracy across WAV, FLAC, MP3, WEBM, M4A, and OGG formats). All generated audio is watermarked at inference time before leaving the infrastructure. The platform exposes REST APIs and SDKs, supports on-prem or cloud deployment, and integrates with voice agent frameworks and enterprise identity/KYC pipelines. The DETECT-3B-Omni model outperforms competitors including Hive AI (83.5%) and Reality Defender (71.3%) on independent benchmarks.
