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:

{
  "emotion": "angry",
  "wav_path": "..."
}

Supported Emotions

• angry
• disgust
• fearful
• happy
• neutral
• sad
• surprised
