VibeVoice-ASR-Streaming-7B

AWQ 4-bit quantization

This repository is a Gaia-produced 4-bit AWQ quantization of `microsoft/VibeVoice-ASR-Streaming-7B`. The Qwen2 language-model decoder is quantized with AutoAWQ using 4-bit, group-size 128, GEMM-compatible weights. The VibeVoice acoustic and semantic tokenizers/connectors remain BF16 to preserve multimodal streaming ASR behavior. The original model is a BF16 checkpoint reported as ~9B parameters despite the repository's 7B name.

The model requires the VibeVoice vLLM plugin from Microsoft's `VibeVoice` repository and a vLLM build with AWQ support. The quantized decoder is in decoder-awq/; the root configuration preserves the streaming architecture and points the plugin to it.

Quantization used 128 ASR/transcription-oriented calibration prompts. This is weight-only quantization; speech-tokenizer weights were not quantized.  

VibeVoice-ASR-Streaming is a unified streaming ASR model that transcribes Who (Speaker) said What (Content), with support for Customized Hotwords and 10 languages.
