About Zonos
Zonos-v0.1 is a text-to-speech model from Zyphra, trained on more than 200,000 hours of varied multilingual speech. It can clone a voice from a reference sample and offers conditioning controls that shape how expressive the output sounds.
The repository includes a Gradio web interface, a sample script, a Dockerfile and a docker-compose file for running it on your own machine. It suits people who want expressive speech synthesis without sending text to a hosted service.
