Choose Confucius4-TTS if…
- License: Confucius4-TTS is Other, TensorFlowTTS is Apache-2.0.
- Tags unique to Confucius4-TTS: audio, cross-lingual, deep-learning, fine-tuning.
- Project requires support for multiple languages without the necessity of model fine-tuning.
When NOT to use Confucius4-TTS
- When project strictly demands language-specific TTS refinement and customization.
- For scenarios needing real-time low-latency TTS performance as Confucius4-TTS focuses on cross-lingual capabilities rather than speed optimizations.
Choose TensorFlowTTS if…
- License: TensorFlowTTS is Apache-2.0, Confucius4-TTS is Other.
- Tags unique to TensorFlowTTS: chinese-tts, fastspeech, fastspeech2, german-tts.
- TensorFlowTTS ships Docker support for self-hosted deployment.
- When you need state-of-the-art real-time text-to-speech functionality across several languages including English, French, Korean, Chinese, German,
When NOT to use TensorFlowTTS
- When you require a text-to-speech solution that works on operating systems other than Ubuntu 18.04 as it has been tested only on this specific environment
- If your project cannot meet the hardware requirements such as needing CUDA 10.1 and CuDNN 7.6.5, or if you want to avoid dependency on TensorFlow-specific packages like TensorFlow Addons
