CosyVoice 2.0 has been optimized and upgraded in many ways:
- Pronunciation accuracy improvement: Significantly reduced pronunciation errors 30%-50% and improved clarity of speech synthesis
- sound enhancement: Improved model architecture using optimization algorithms to improve its MOS (Mean Opinion Score) score from 5.4 to 5.53
- Rhythmic Naturalness Enhancement: Improved the intonation and rhythm of the voice, making the generated voice more natural and fluent
- <strong]Delay Optimization: First-packet latency as low as 150ms under streaming synthesis, more suitable for real-time interaction scenarios
- <strong]Model Simplification: Reduced computational complexity through architectural optimization, allowing it to operate more efficiently while maintaining high quality
These improvements enable CosyVoice 2.0 to achieve near-commercial level speech synthesis quality for demanding application scenarios such as voice assistants and content creation.
