# Synthesis SER Dataset

## Overview

This dataset contains **synthetic speech audio files** for Speech Emotion Recognition (SER) training, specifically designed for training the **emotion2vec** model. The data is generated using two state-of-the-art TTS systems: **CosyVoice2** and **Kimi-Audio**.

## Dataset Structure

Each subdirectory corresponds to a source emotional speech dataset and contains synthetic data generated using both TTS engines:

| Subdirectory | Source | TTS Engines | # WAV Files |
|-------------|--------|-------------|-------------|
| `CREMA_D_SYN.tar.gz` | CREMA-D | CosyVoice2 + Kimi-Audio | 2,236 |
| `IEMOCAP_SYN.tar.gz` | IEMOCAP | CosyVoice2 + Kimi-Audio | 3,570 |
| `LLM_DATA_SYN.tar.gz` | LLM_DATA | CosyVoice2 + Kimi-Audio | 3,155 |
| `RAVDESS_SYN.tar.gz` | RAVDESS | CosyVoice2 + Kimi-Audio | 12 |
| `SAVEE_SYN.tar.gz` | SAVEE | CosyVoice2 + Kimi-Audio | 124 |
| `TESS_SYN.tar.gz` | TESS | CosyVoice2 + Kimi-Audio | 12,397 |

### Internal Structure

Each tar.gz contains:
```
├── cosyvoice2/
│   ├── train/
│   │   ├── *.wav
│   │   └── train.json
│   └── test/
│       ├── *.wav
│       └── test.json
└── kimi-audio/
    ├── train/
    │   ├── *.wav
    │   └── train.json
    └── test/
        ├── *.wav
        └── test.json
```

Each `train.json` / `test.json` contains metadata:
```json
{
  "emotion": "angry",
  "wav_path": "..."
}
```

### Supported Emotions

- angry
- disgust
- fearful
- happy
- neutral
- sad
- surprised

## Real Data Sources

Since the real emotional speech data is publicly available, we only host the **synthetic** data on HuggingFace. If you need the **real** data for research, please download from the original sources:
