Shared compatibility
- Python · TTS: Python runtime · chatterbox-tts-api: Python runtime
Choose TTS if…
- License: TTS is MPL-2.0, chatterbox-tts-api is AGPL-3.0.
- Tags unique to TTS: deep-learning, glow-tts, hifigan, melgan.
- Also covers Model Training.
- TTS ships Docker support for self-hosted deployment.
- If you are working on research projects that require advanced models such as Glow-TTS, HifiGAN, or MelGAN for high-quality speech synthesis
When NOT to use TTS
- If your project strictly requires a lightweight installation without the overhead of extra dependencies included when installing 🐸TTS from source for development purposes
- In cases where you are restricted to older Python versions less than 3.9, as 🐸TTS is tested on systems with python >= 3.9 but < 3.12
Choose chatterbox-tts-api if…
- License: chatterbox-tts-api is AGPL-3.0, TTS is MPL-2.0.
- Requirements: Requires a local setup environment that supports CUDA for optimal performance; Docker can simplify deployment..
- Tags unique to chatterbox-tts-api: ai, chatgpt, chatterbox, cuda.
- When you need a self-hosted solution that mirrors the functionality of ElevenLabs or other proprietary TTS services and requires compatibility with existing ecosystems like Open WebUI or AnythingLLM.
When NOT to use chatterbox-tts-api
- If you require integrations specific to ElevenLabs' proprietary voice models as Chatterbox-TTS-API, despite its capabilities, does not directly support their unique voice libraries.
- For users needing a fully managed service without the complexities of local deployment and maintenance, like that offered by cloud-based TTS providers.
