Shared compatibility
- Python · ChatTTS: Python runtime · metavoice-src: Python runtime
Choose ChatTTS if…
- License: ChatTTS is AGPL-3.0, metavoice-src is Apache-2.0.
- Requirements: Python-based implementation means that familiarity with Python is necessary for effective use..
- Tags unique to ChatTTS: agent, chatgpt, chattts, chinese language.
- Also covers AI Agents.
- Use ChatTTS when you require text-to-speech functionality for daily dialogue applications, especially those involving Chinese or English languages.
When NOT to use ChatTTS
- Avoid using ChatTTS in environments where the speech generation model is expected to handle complex technical jargon or specialized vocabulary, as it's optimized for daily conversation.
- Do not use ChatTTS if your project requires the integration of more than two languages simultaneously due to its current support for only Chinese and English.
Choose metavoice-src if…
- License: metavoice-src is Apache-2.0, ChatTTS is AGPL-3.0.
- Tags unique to metavoice-src: ai, deep-learning, pytorch, speech.
- metavoice-src ships Docker support for self-hosted deployment.
- When aiming for high-fidelity human-like TTS quality leveraging advanced deep learning approaches
When NOT to use metavoice-src
- For users lacking a GPU with at least 12GB VRAM
- Without Python version 3.10 to 3.12, metavoice-src might not function properly
