Open-source emotive text-to-speech foundation model with low conversational latency.

Visit misolabs.ai ↗

Miso-TTS is an open-source 8B parameter speech synthesis foundation model developed by Miso Labs. It generates expressive, human-like voice with a fast 110ms response latency and supports one-shot voice cloning. The model can be run locally on-premises or accessed via an API, allowing developers to build real-time voice agents without third-party data exposure.

What it's for

  • Build real-time conversational voice agents for customer support or assistants
  • Clone a speaker's voice using a 10-second reference audio sample
  • Deploy a low-latency speech synthesis model locally for strict data privacy requirements

Features

  • 8B parameter architecture built on Llama 3.2 and Mimi audio tokenizer
  • 110ms response latency for natural, uninterrupted conversational flow
  • One-shot voice cloning from a 10-second audio sample
  • Emotive and expressive vocal inflections
  • Available for local, on-premises deployment as well as cloud API access

Pricing

Open source. Open-source model download; API access and enterprise support contracts available
