Wheels
Python: 3.10, 3.11, 3.12, 3.13, 3.14 (Requires-Python >=3.10). Every wheel is py3-none, so one file serves all of them.
The x86-64 wheels (Linux x86_64 and Windows x64, every variant) need a CPU with AVX2, FMA, F16C and BMI2 (Intel Haswell, AMD Zen or newer).

Install
All variants share the distribution name nemo-speech, so install the file for your platform and backend directly (a version specifier with -f would let pip pick a GPU variant). For example:
pip install https://github.com/PNL-toshiyaishihara/nemo-speech-python/releases/download/v0.1.0/nemo_speech-0.1.0+cu128-py3-none-manylinux_2_27_x86_64.manylinux_2_28_x86_64.whlGPU wheels bundle their runtime libraries (CUDA runtime, cuBLAS) and need only the GPU driver. nemo_speech.build_info() reports how an installation was built. SHA256SUMS lists the checksums of all files.
