The README presents NeMo Speech as NVIDIA's speech toolkit with open-weight checkpoints.

Source: https://github.com/nvidia-nemo/speech

What it supplies: The README presents NeMo Speech as NVIDIA's speech toolkit with open-weight checkpoints.

Useful for: - Use released checkpoints from the Hugging Face collection.
- Install the asr and tts extras for recognition and synthesis work.

First action: - Clone the repository and run uv sync with the extras for your CUDA version.
- Or install the nemo-toolkit asr and tts extras on your own PyTorch stack.

Prerequisites and limits: The README lists Python 3.12 or above and PyTorch 2.7 or above, with an NVIDIA GPU and CUDA required for training and recommended for inference.

- Training needs an NVIDIA GPU.
- Release naming changed with a repository split, so older versions live elsewhere.

Source-documented: a badge names Apache 2.0. Checkpoints on Hugging Face carry their own model licences.

Written from the README text only. Statements are as the README gives them; nothing was installed or run.
Based on updates, requirements, install and licence badge README text only; other sections were not read in full. Nothing was installed or run.
