+# 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:
