## Overview

TruthShield VoiceGen is an advanced text-to-speech system supporting 11 languages with voice cloning, accent transfer, and style control capabilities. Built with safety-first principles using forensic speaker verification.

## Features

- 🌍 **11 Languages**: Hindi, Bengali, Telugu, Tamil, Kannada, Marathi, Gujarati, Bhojpuri, Maithili, Chhattisgarhi, Magahi, English
- 🎤 **Voice Cloning**: Clone voices from short reference audio
- 🗣️ **Accent Transfer**: Transfer accents while preserving content
- 🎭 **Style Control**: Adjust speaking style and emotion
- 🛡️ **Safety Verification**: ECAPA-TDNN forensic verification

## Quick Start

### Installation

```bash
git clone https://github.com/truthshield/voicegen.git
cd voicegen
pip install -r requirements.txt
```

### Run Server

```bash
uvicorn server:app --host 0.0.0.0 --port 8080

```

## Safety Layer

All generated audio passes through ECAPA-TDNN speaker verification:

1. Extract speaker embeddings from reference
2. Generate audio using VITS
3. Extract embeddings from generated audio
4. Compute similarity score
5. Apply threshold (0.85) for verification
