# ZipVoice⚡: Fast and High-Quality Zero-Shot Text-to-Speech with Flow Matching</center>

This model consists of checkpoints for two fast and high-quality non-autoregressive zero-shot text-to-speech models:

- **ZipVoice**, for single-speaker speech generation. Details in [paper](https://arxiv.org/abs/2506.13053) and [demo](https://zipvoice.github.io).


- **ZipVoice-Dialog**, for spoken dialogue generation. Details in [paper](https://arxiv.org/abs/2507.09318) and [demo](https://zipvoice-dialog.github.io).

See our Github repository [ZipVoice](https://github.com/k2-fsa/ZipVoice) for instructions on using our models.
