SpeakEasy Nemotron 3.5 Streaming English — CUDA

This repository contains the SpeakEasy-derived float32 ONNX pack used by the Windows CUDA streaming-ASR path. It is an application-specific export, not an official NVIDIA ONNX release and is not endorsed by NVIDIA.

The upstream checkpoint is NVIDIA's `nemotron-3.5-asr-streaming-0.6b`, pinned to revision f3d333391852ba876df169dcc9ba902d25b6ab0b. SpeakEasy exported the 320 ms float32 ONNX files with the pinned environment in `scripts/model-export` using NeMo revision 23de54bb6d5c1c4abd97c8d51b8c20e91447dd32.
