Zonos-v0.1 is an open-weight text-to-speech model trained on over 200k hours of multilingual speech, with a Python library for inference. It supports zero-shot voice cloning from short reference clips and fine-grained conditioning on speaking rate, pitch, quality, and emotions, outputting 44kHz audio.

Use cases

  • generate natural speech from text
  • clone a voice from a short audio sample
  • create expressive TTS with emotion control
  • build a multilingual voiceover generator
  • run open-source TTS locally on GPU
  • generate speech at 44kHz quality

When to choose

  • you need high-quality open-weight TTS with voice cloning
  • you want local inference without relying on hosted TTS APIs
  • you need control over emotion, pitch, and speaking rate
  • you need multilingual speech generation

When to avoid

  • you need a lightweight CPU-only TTS solution
  • you need a fully managed hosted service
  • you need non-Python integration without GPU resources
