Voice developers can download the weights and clone voices from ten seconds of audio, but hosted API pricing is unpublished.

Kenning's take

What it does

MisoTTS is an 8 billion parameter speech model that generates voice from both text and the audio of the person speaking, so replies can match their tone. Miso Labs says it responds in about 110 milliseconds and can clone a voice from a ten-second clip. The weights are free on Hugging Face with code on GitHub, and hosted API access was listed as coming soon at launch.

  • 8B parameter model conditioned on text and audio
  • One-shot voice cloning from a ten-second clip
  • About 110 ms response latency (maker's figure)
  • Open weights for local deployment
  • On-premises hosting and support contracts for enterprises

Who it suits. Developers building voice agents who want an expressive speech model they can run themselves.
