Shared compatibility
- Python · Chatterbox-TTS-Server: Python runtime · hifi-gan: Python runtime
Choose Chatterbox-TTS-Server if…
- Requirements: Python 3.10 needed for pre-built wheels; avoid Python >=3.11 due to lack of support.; Ensure hardware and driver meets the Hardware Compatibility Matrix requirements..
- Tags unique to Chatterbox-TTS-Server: ai, api-server, audio-generation, chatterbox.
- Chatterbox-TTS-Server ships Docker support for self-hosted deployment.
- You need a self-hosted Text-to-Speech service that supports advanced features like voice cloning.
When NOT to use Chatterbox-TTS-Server
- When only pre-built wheels and no flexibility with Python versions is required (strictly follows Python 3.10).
- If your hardware or OS lacks support detailed in the compatibility matrix, like unsupported GPUs/CPU setups.
- For projects requiring minimal dependencies without manual handling of installation intricacies.
Choose hifi-gan if…
- Tags unique to hifi-gan: deep-learning, gan, hifi-gan, speech-synthesis.
- When you require real-time generation capabilities up to 167.9 times faster than real time on a single V100 GPU, or even 13.4 times faster on CPU than real time for the small footprint version
- More GitHub stars (2.4k vs 1.4k) - visibility, not fit.
When NOT to use hifi-gan
- If your application prioritizes sample quality above speed, despite the competitive position of HiFi-GAN in both criteria
- When the computational resources for running models on a V100 GPU or leveraging the small footprint version's CPU efficiency are not available
- In scenarios requiring more than just high-fidelity speech synthesis but also complex text-to-speech natural language processing capabilities
