+
+## 📖 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
