# 🇮🇳 Hindi Voice Cloning with Emotion
This Hugging Face Space provides **high-quality Hindi Text-to-Speech with voice cloning and expressive emotion**.
Users can upload a short reference voice sample and generate Hindi speech in the **same voice, tone, and emotional style**.
The system is powered by **VibeVoice-7B** with **Hindi LoRA fine-tuning**, optimized for natural prosody and long-form speech.
---
## ✨ Features
- 🎙️ Voice cloning from uploaded reference audio
- 🎭 Emotion & speaking style transfer
- 🗣️ Natural-sounding Hindi TTS
- 📄 Long-form narration support
- 🚀 GPU-accelerated inference

## 🎧 Reference Voice Guidelines (Very Important)
For best quality voice cloning:
- WAV format only
- 10–30 seconds duration recommended
- Single speaker
- Clear audio, minimal background noise
- Natural emotion (happy, calm, sad, etc.)
> ⚠️ Emotion is copied from the **reference voice**, not from the text.
