It supports extensive capabilities including fine-tuning, TTS (Text-To-Speech), and natural language generation. ## Choose when ### Choose CosyVoice if… - CosyVoice is primarily Python; tensorspace is JavaScript. - 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 tensorspace if… - tensorspace is primarily JavaScript; CosyVoice is Python. - Tags unique to tensorspace: 3d, deep-learning, keras, machine-learning. - Leaner open-issue backlog (28). ## 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 tensorspace - Last GitHub push was 1314 days ago (dormant maintenance, Dec 5, 2022). Validate activity before betting a new project on tensorspace. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ## Common questions ### What is the difference between CosyVoice and tensorspace?
