Model Card

A browser-friendly build of nvidia/nemotron-3.5-asr-streaming-0.6b, NVIDIA's multilingual cache-aware FastConformer RNNT with native streaming, punctuation, capitalization, and language-ID prompting (40 language-locales, 19 transcription-ready). Used by Twitch Live Captions for on-device live captions. It is derived from the sherpa-onnx export csukuangfj2/sherpa-onnx-nemotron-3.5-asr-streaming-0.6b-560ms-2026-06-11. The encoder's MatMul weights are quantized to 4 bits with ONNX Runtime's MatMulNBitsQuantizer (block size 32, symmetric), shrinking it from 2.5 GB to 683 MB. The decoder and joiner are unchanged fp32. Auto-detection can misfire at the start of an utterance (for example, a few…

speaker-diarization-3.1

Pyannote

Using this open-source model in production? Consider switching to pyannoteAI for better and faster options. This pipeline is the same as pyannote/speaker-diarization-3.0 except it removes the problematic use of onnxruntime. Both speaker segmentation and embedding now run in pure PyTorch. This should ease deployment and possibly speed up inference. It requires pyannote.audio version 3.1 or higher. It ingests mono audio sampled at 16kHz and outputs speaker diarization as an Annotation instance: - stereo or multi-channel audio files are automatically downmixed to mono by averaging the channels. - audio files sampled at a different rate are resampled to 16kHz automatically upon loading. 1.…

Pyannote

This pipeline ingests mono audio sampled at 16kHz and outputs speaker diarization. - stereo or multi-channel audio files are automatically downmixed to mono by averaging the channels. - audio files sampled at a different rate are resampled to 16kHz automatically upon loading. The main improvements brought by Community-1 are: - improved speaker assignment and counting - simpler reconciliation with transcription timestamps with exclusive speaker diarization - easy offline use (i.e. without internet connection) - (optionally) hosted on pyannoteAI cloud 1. pip install pyannote.audio 3. Create access token at hf.co/settings/tokens. Out of the box, Community-1 is much better than…

faster-whisper-small

Systran

This repository contains the conversion of openai/whisper-small to the CTranslate2 model format. This model can be used in CTranslate2 or projects based on CTranslate2 such as faster-whisper. The original model was converted with the following command: Note that the model weights are saved in FP16. This type can be changed when the model is loaded using the computetype option in CTranslate2. For more information about the original model, see its model card.
