Frequently Asked Questions
CosyVoice2 is a next-generation text-to-speech model from FunAudioLLM (Alibaba). It supports zero-shot voice cloning from just a few seconds of reference audio and can synthesize natural speech in Chinese, English, Japanese, Korean, and Cantonese.
Yes, CosyVoice2 is fully Apache 2.0 licensed - both code and model weights. It can be used freely in commercial applications.
CosyVoice2 supports Chinese (Mandarin), English, Japanese, Korean, and Cantonese. It also supports cross-lingual voice cloning - clone a voice in one language and generate speech in another.
Provide 3-10 seconds of reference audio. CosyVoice2 extracts speaker characteristics using finite scalar quantization and can then generate new speech in that voice across all supported languages.
Both offer voice cloning with similar quality. CosyVoice2 supports more languages (5 vs 2) and has streaming capability. F5-TTS may be slightly faster for English-only applications.
CosyVoice2 requires 4-6GB of VRAM for the 0.5B parameter model. A GPU with 6GB or more is recommended for optimal performance.
