Microsoft Releases VibeVoice-ASR-BitNet: 1.58GB Speech Recognition Model Runs Real-Time on CPU, No GPU Needed
Microsoft Research released VibeVoice-ASR-BitNet, a quantized 1.58GB version of its VibeVoice-ASR speech recognition model that achieves real-time inference (RTF < 1) on as few as 3 CPU threads. The model runs 1.6-2.3x faster than Whisper.cpp on commodity x86 and ARM hardware, with a modest accuracy tradeoff.
