Shared compatibility
- Python · TTS: Python runtime · espnet: Python runtime
Choose TTS if…
- License: TTS is MPL-2.0, espnet is Apache-2.0.
- Tags unique to TTS: glow-tts, hifigan, melgan, multi-speaker-tts.
- 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 espnet if…
- License: espnet is Apache-2.0, TTS is MPL-2.0.
- Tags unique to espnet: chainer, kaldi, speech recognition, speech-synthesis.
- When you require comprehensive tools for end-to-end speech processing tasks such as speech recognition, synthesis, translation, and speaker diarization.
When NOT to use espnet
- If you are working on tasks unrelated to speech or audio processing, such as computer vision, NLP, or any other deep learning areas outside of ESPNet's focus.
- Your development environment is limited to languages other than Python or frameworks that do not support Chainer or PyTorch, which are foundational to espnet.
