Choose ChatTTS if…
- License: ChatTTS is AGPL-3.0, Amphion is MIT.
- Requirements: Optional installations like vLLM and TransformerEngine are available but come with specific warnings and limitations..
- Tags unique to ChatTTS: agent, chat, chatgpt, chattts.
- Also covers LLM Frameworks.
- When you need a tool that supports both Chinese and English for daily dialogue generation.
When NOT to use ChatTTS
- If you are working on a project that requires the use of TransformerEngine with NVIDIA GPU, as it is currently under development and cannot run properly.
- When you need fast text-to-speech generation, as the optional installation of FlashAttention-2 can slow down the generating speed.
- If you are not comfortable with a slow installation process, as noted in the repository documentation.
Choose Amphion if…
- License: Amphion is MIT, ChatTTS is AGPL-3.0.
- Tags unique to Amphion: audio-generation, music-generation, singing-voice-conversion, speech-synthesis.
- Amphion ships Docker support for self-hosted deployment.
- When you are new to the field of audio, music, or speech generation and seeking a toolkit that simplifies setup with Python dependencies and Docker images.
When NOT to use Amphion
- If you require advanced customization beyond what the provided Python packages offer, since Amphion caters more to getting started quickly without deep configuration.
