# BreezeBlue's Breeze TTS 2 Clones and Designs Voices in Under 40ms

> BreezeBlue open-sourced a 3B bilingual TTS model that tops the Artificial Analysis leaderboard with sub-40ms latency and natural-language voice design.

Text-to-speech has become one of the most competitive open-weight benchmarks in AI, and BreezeBlue just released [Breeze TTS 2](https://huggingface.co/BreezeBlue/Breeze-TTS-2), a 3B-parameter speech model that combines voice cloning, natural-language voice design, and low-latency streaming in a single checkpoint runnable on a 12 GB GPU.

The model targets real-time voice AI for games, agents, and interactive stories. Voice Design generates a distinctive voice from a text prompt alone. Voice Direction then steers tone, emotion, and pace on top of any cloned identity. Both work in English and Chinese from the same checkpoint, with inline vocal events like (laugh) or (sigh) embedded directly in the text.

## What's in the checkpoint

The model is a 3B-parameter transformer distributed on Hugging Face with a PyTorch inference stack. Key capabilities:

* **Voice Clone** from a reference audio file and its transcript
* **Voice Design** from a natural-language description, no reference recording needed
* **Voice Direction** that clones a voice while steering delivery for a specific line
* **Inline Vocal Events** using parentheses in English and square brackets in Chinese

_Preview only. Full text requires an AlphaSignal Pro account._
