## 📖 Overview

The DualTalk dataset is the first large-scale dataset specifically designed for dual-speaker 3D talking head conversation generation. This dataset supports speaker and listener role transitions, multi-round conversations, and natural interactions, providing essential benchmark data for the 3D talking head generation field.

## 🎯 Dataset Features

- **Dual-Speaker Interaction**: Contains synchronized audio and facial expression data from two speakers
- **Role Transition**: Supports dynamic transitions between speaker and listener roles
- **Multi-Round Conversations**: Provides continuous multi-round conversation data
- **High-Quality Annotations**: Includes precise FLAME parameters and audio features
- **Diverse Scenarios**: Covers various conversation scenarios and emotional expressions
