## What stands out

- 60-minute single-pass ASR with diarization: VibeVoice-ASR (~9B params incl. Qwen2-based decoder) transcribes up to 60 min in one pass with who/when/what structured output, hotwords and 50+ languages with code-switching. Source: https://huggingface.co/microsoft/VibeVoice-ASR
- CPU-only realtime ASR (found after launch): VibeVoice-ASR-BitNet (2026-07-23) compresses the model 4.62 GB -> 1.58 GB and runs faster than real time on 3 CPU threads (1.6-2.3x faster than Whisper.cpp). Source: https://huggingface.co/microsoft/VibeVoice-ASR-BitNet
- Streaming speaker-attributed ASR (found after launch): VibeVoice-ASR-Streaming (7B and 1.5B repos, uploaded 2026-09-02) transcribes live audio with speaker attribution (who said what) and custom hotwords in 10 languages (zh, en, fr, de, it, ja, ko, pt, ru, es); MIT license. Source: https://huggingface.co/microsoft/VibeVoice-ASR-Streaming-7B
- Long-form multi-speaker TTS (withdrawn) (found after launch): Original VibeVoice-TTS (1.5B/7B) generated up to 90 min with 4 speakers; Microsoft removed the TTS code on 2025-09-05 over responsible-AI misuse concerns. Source: https://github.com/microsoft/VibeVoice
