Open-weight text-to-speech model with voice cloning and fine-grained emotion control

Visit maia.zyphra.com ↗

Zonos-v0.1 is an open-weight speech generation model developed by Zyphra and trained on over 200,000 hours of multilingual audio. It provides voice cloning from short audio clips alongside conditioning controls for speaking rate, pitch, and specific emotions, delivering audio natively at 44kHz.

What it's for

  • Clone target voices using a reference audio clip of a few seconds
  • Generate expressive speech with specific emotional inflections like anger, fear, or happiness
  • Produce high-sample-rate spoken audio for podcasts, videos, or games

Features

  • Voice cloning from short reference audio clips or speaker embeddings
  • Conditioning controls for emotion, speaking rate, pitch variation, and audio quality
  • Native 44kHz audio output
  • Trained on over 200,000 hours of multilingual speech data
