+### Flash Attention (audio generation)
+
+For **audio generation** (e.g. TTS variants, multi-turn spoken dialogue with audio output), install the **`flash-attn`** package with a build that matches your **CUDA** and **PyTorch** versions. On GPU, omitting **`flash-attn`** can cause **generated audio to be noise-only or otherwise unusable**. See the [FlashAttention](https://github.com/Dao-AILab/flash-attention) project for installation options and prebuilt wheels.

 ## Quick Start
 
 Run a single sample for basic TTS:

+> ⚠️ **Important (audio generation)**  
+> For **audio generation** (TTS, responses that include synthesized audio, etc.), install **`flash-attn`** for your **CUDA** and **PyTorch** stack. Without it on GPU, **output audio may be noise-only or unusable**. See the [FlashAttention](https://github.com/Dao-AILab/flash-attention) repository for compatible builds.
