Shared compatibility

Choose VoxCPM if…
- License: VoxCPM is Apache-2.0, chatterbox-tts-api is AGPL-3.0.
- Requirements: Python >= 3.10 (<3.13), PyTorch >= 2.5.0, CUDA >= 12.0.; For production deployment, Nano-vLLM is recommended for its high throughput and concurrent request support..
- Tags unique to VoxCPM: audio, deeplearning, minicpm, multilingual.
- Also covers Inference & Serving.
- When you need to generate high-quality, lifelike voice clones for multiple languages without the overhead of tokenizers.
When NOT to use VoxCPM
- If your project is constrained by hardware with less powerful GPUs than NVIDIA RTX 4090, as VoxCPM might not provide optimal real-time factor performance.
- When a simple text-to-speech solution suffices and does not require the advanced features like voice cloning or creative voice design that VoxCPM offers.
Choose chatterbox-tts-api if…
- License: chatterbox-tts-api is AGPL-3.0, VoxCPM is Apache-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.
