## Decision facts: CosyVoice

- **Adopt for:** CosyVoice is a Python-based multi-lingual large voice generation model. It supports extensive capabilities including fine-tuning, TTS (Text-To-Speech), and natural language generation.

## Choose when

### Choose CosyVoice if…

- License: CosyVoice is Apache-2.0, learn2learn is MIT.
- Tags unique to CosyVoice: audio-generation, cantonese, chatbot, chatgpt.
- Also covers Inference & Serving, Speech & Audio.
- When you need support for multiple languages like Cantonese, Chinese, English, Japanese, and Korean.

### Choose learn2learn if…

- License: learn2learn is MIT, CosyVoice is Apache-2.0.
- Tags unique to learn2learn: few-shot, finetuning, learn2learn, learning2learn.
- Leaner open-issue backlog (34).

## When NOT to use CosyVoice

- If your project specifically requires fine-tuned performance in languages not supported by CosyVoice such as Arabic or Spanish.
- When strict real-time speech synthesis requirements are essential, as CosyVoice may face delays depending on the environment's computational power and model complexity.

## When NOT to use learn2learn

- Last GitHub push was 207 days ago (slowing maintenance, Dec 16, 2025). Validate activity before betting a new project on learn2learn.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
