title: 'Extremely-Fast diffusion text-to-speech synthesis pipeline with ProDiff and FastDiff'
description: |
  Gradio demo for **2-iter** ProDiff and **4-iter** FastDiff. To use it, simply add your audio, or click one of the examples to load them. **This space is running on CPU, inference will be slower.**

  ## Key Features
  - **Extremely-Fast** diffusion text-to-speech synthesis pipeline for potential **industrial deployment**.
  - **Tutorial and code base** for speech diffusion models.
  - More **supported diffusion mechanism** (e.g., guided diffusion) will be available.
