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.
