<h3>📰 News</h3>




<strong>2026-03-06: 🚀 VibeVoice ASR is now part of a <a href="https://huggingface.co/microsoft/VibeVoice-ASR-HF">Transformers release</a>! You can now use our speech recognition model directly through the Hugging Face Transformers library for seamless integration into your projects.</strong>

<strong>2026-01-21:</strong> 📣 We open-sourced <a href="docs/vibevoice-asr.md"><strong>VibeVoice-ASR</strong></a>, a unified speech-to-text model designed to handle 60-minute long-form audio in a single pass, generating structured transcriptions containing Who (Speaker), When (Timestamps), and What (Content), with support for User-Customized Context. Try it in [Playground](https://aka.ms/vibevoice-asr).
- ⭐️ VibeVoice-ASR is natively multilingual, supporting over 50 languages — check the [supported languages](docs/vibevoice-asr.md#language-distribution) for details.
- 🔥 The VibeVoice-ASR [finetuning code](finetuning-asr/README.md) is now available!
- ⚡️ **vLLM inference** is now supported for faster inference; see [vllm-asr](docs/vibevoice-vllm-asr.md) for more details.
- 📑 [VibeVoice-ASR Technique Report](https://arxiv.org/pdf/2601.18184) is available.
- 📑 [VibeVoice-ASR Technical Report](https://arxiv.org/pdf/2601.18184) is available.

2025-12-16: 📣 We added experimental speakers to <a href="docs/vibevoice-realtime-0.5b.md"><strong>VibeVoice‑Realtime‑0.5B</strong></a> for exploration, including multilingual voices in nine languages (DE, FR, IT, JP, KR, NL, PL, PT, ES) and 11 distinct English style voices. [Try it](docs/vibevoice-realtime-0.5b.md#optional-more-experimental-voices). More speaker types will be added over time.

2025-12-03: 📣 We open-sourced <a href="docs/vibevoice-realtime-0.5b.md"><strong>VibeVoice‑Realtime‑0.5B</strong></a>, a real‑time text‑to‑speech model that supports streaming text input and robust long-form speech generation. Try it on [Colab](https://colab.research.google.com/github/microsoft/VibeVoice/blob/main/demo/vibevoice_realtime_colab.ipynb).

2025-09-05: VibeVoice is an open-source research framework intended to advance collaboration in the speech synthesis community. After release, we discovered instances where the tool was used in ways inconsistent with the stated intent. Since responsible use of AI is one of Microsoft’s guiding principles, we have removed the VibeVoice-TTS code from this repository.


2025-08-25: 📣 We open-sourced <a href="docs/vibevoice-tts.md"><strong>VibeVoice-TTS</strong></a>, a long-form multi-speaker text-to-speech model that can synthesize speech up to 90 minutes long with up to 4 distinct speakers. — accepted as an [Oral](https://openreview.net/forum?id=FihSkzyxdv) at ICLR 2026! 🔥

## ⚠️ Risks and Limitations

While efforts have been made to optimize it through various techniques, it may still produce outputs that are unexpected, biased, or inaccurate. VibeVoice inherits any biases, errors, or omissions produced by its base model (specifically, Qwen2.5 1.5B in this release).

Potential for Deepfakes and Disinformation: High-quality synthetic speech can be misused to create convincing fake audio content for impersonation, fraud, or spreading disinformation. Users must ensure transcripts are reliable, check content accuracy, and avoid using generated content in misleading ways. Users are expected to use the generated content and to deploy the models in a lawful manner, in full compliance with all applicable laws and regulations in the relevant jurisdictions. It is best practice to disclose the use of AI when sharing AI-generated content.
