 <strong>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).</strong>
 
-<strong>2025-12-09: 📣 We’ve added experimental speakers in nine languages (DE, FR, IT, JP, KR, NL, PL, PT, ES) for exploration—welcome to try them out and share your feedback.</strong>
+<strong>2025-12-09: 📣 We added experimental speakers in nine languages (DE, FR, IT, JP, KR, NL, PL, PT, ES) for exploration—welcome to try them out and share your feedback.</strong>
+
+<strong>2025-12-16: 📣 We added more experimental speakers for exploration, including multilingual voices 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.</strong>

 To mitigate deepfake risks and ensure low latency for the first speech chunk, voice prompts are provided in an embedded format. For users requiring voice customization, please reach out to our team. We will also be expanding the range of available speakers.

 ## 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 0.5b in this release).
