short_description: ZeroGPU Nano-TTS voice clone demo
---

This Space supports `voice_clone` only and is designed for Hugging Face ZeroGPU.

The runtime keeps `device="auto"` and does not expose frontend controls for switching CPU execution or backend backbone selection.

Upload a reference audio file or use a built-in preset voice, then generate the full output audio after decoding finishes.

The UI also supports selecting built-in example cases from `assets/demo.jsonl`, which auto-fill the text and preview the effective prompt audio.
