Frontier TTS, voice cloning, and dubbing. Industry default.

Hosted speech synthesis at near-human quality — TTS, voice cloning, multilingual dubbing, and conversational voice agents. Default choice when you need a voice that sounds like a person, not a robot.

Low-latency streaming TTS. Sub-100ms first audio.

Streaming-first speech synthesis built around the Sonic family of state-space models. Aims at real-time agent voices where latency between turns is the product. Strong choice for sub-200ms voice loops.

Production speech-to-text. The STT default for many companies.

End-to-end speech recognition platform — real-time streaming, batch transcription, speaker diarization, and language detection. Strong on accented speech, telephony audio, and long-form recordings.

Voice cloning, audio watermarking, and deepfake detection in one platform.

Resemble AI spans both sides of synthetic voice: generating it and policing it. The platform offers voice cloning and text-to-speech built on its Chatterbox models, real-time audio watermarking, and Detect, a multimodal deepfake detector covering audio, image, and video. It deploys in the cloud or fully on-premises for regulated environments.
