## Highlight🔥
**CosyVoice 2.0** has been released! Compared to version 1.0, the new version offers more accurate, more stable, faster, and better speech generation capabilities.
### Multilingual
- **Support Language**: Chinese, English, Japanese, Korean, Chinese dialects (Cantonese, Sichuanese, Shanghainese, Tianjinese, Wuhanese, etc.)
- **Crosslingual & Mixlingual**：Support zero-shot voice cloning for cross-lingual and code-switching scenarios.
### Ultra-Low Latency
- **Bidirectional Streaming Support**: CosyVoice 2.0 integrates offline and streaming modeling technologies.
- **Rapid First Packet Synthesis**: Achieves latency as low as 150ms while maintaining high-quality audio output.
### High Accuracy
- **Improved Pronunciation**: Reduces pronunciation errors by 30% to 50% compared to CosyVoice 1.0.
- **Benchmark Achievements**: Attains the lowest character error rate on the hard test set of the Seed-TTS evaluation set.
### Strong Stability
- **Consistency in Timbre**: Ensures reliable voice consistency for zero-shot and cross-language speech synthesis.
- **Cross-language Synthesis**: Marked improvements compared to version 1.0.
### Natural Experience
- **Enhanced Prosody and Sound Quality**: Improved alignment of synthesized audio, raising MOS evaluation scores from 5.4 to 5.53.
- **Emotional and Dialectal Flexibility**: Now supports more granular emotional controls and accent adjustments.

**Basic Usage**
For zero_shot/cross_lingual inference, please use `CosyVoice2-0.5B` or `CosyVoice-300M` model.
We strongly recommend using `CosyVoice2-0.5B` for better performance.
For zero_shot/cross_lingual inference, please use `CosyVoice-300M` model.
For sft inference, please use `CosyVoice-300M-SFT` model.
For instruct inference, please use `CosyVoice-300M-Instruct` model.
We strongly recommend using `CosyVoice2-0.5B` model for better streaming performance.
First, add `third_party/Matcha-TTS` to your `PYTHONPATH`.
