Choose espnet if…
- Tags unique to espnet: chainer, deep-learning, kaldi, pytorch.
- When you require comprehensive tools for end-to-end speech processing tasks such as speech recognition, synthesis, translation, and speaker diarization.
- Leaner open-issue backlog (49).
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.
Choose Speech if…
- Tags unique to Speech: asr, deeplearning, generative-ai, machine-translation.
- Also covers Developer Tools.
- When working on projects that require extensive GPU utilization for training large models due to its support for efficient CUDA usage.
When NOT to use Speech
- For environments where GPU access is limited or unavailable since the toolkit highly recommends a GPU setup for both training and recommended for inference.
- If your Python/PyTorch/CUDA versions fall below the specified requirements (Python 3.12+, PyTorch 2.7+), as lower versions will not be compatible with NeMo Speech.
- In scenarios where you're working with models that do not require or benefit significantly from GPU acceleration, given its architecture optimized for GPU use.
