# SingMoSub

## Overview
**SingMoSub** is the first dataset featuring **motion subtitles** specifically designed for **singing-driven 3D head motion**. It provides temporally aligned, region-level motion annotations along with acoustic descriptions, enabling detailed modeling of expressive head and facial dynamics in singing scenarios.

The dataset contains over 37 hours of synchronized multimodal data, including:
- **Singing audio** corresponding to each motion sequence;
- **3D facial motion** captured as FLAME parameters (56 dimensions: 50 expression, 3 neck pose, 3 jaw pose);
- **Multimodal subtitles** for 4 regions motion subtitles (eyebrows, eyes, mouth, neck) and acoustic description subtitles in SRT format.
