## What it is
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
