NVIDIA's Magpie provides a separately deployable speech-generation component for multilingual voice assistants. Its open weightsA model whose trained parameters are published for anyone to download and run — unlike API-only models you can access but never possess.Full definition → allow teams to run and customize that component on their own infrastructure. The release report gives a 32-millisecond time to first audio for one stream on a B200 using NVIDIA's optimized NIM serving container; at 64 streams, the figure rises to 239 milliseconds. These are speech-generation measurements. Speech recognition, language-model processing and other steps still contribute to the wait before a complete assistant responds, so deployment load and the rest of the pipeline remain central to perceived responsiveness.
