New SG-Mamba Model Enhances Audio-Visual Speech with Sparse Graph and Mamba

By PulseAugur Editorial · [1 sources] ·

Researchers have developed SG-Mamba, a novel lightweight framework for audio-visual speech enhancement. This model integrates a sparse heterogeneous graph with a Mamba backbone to improve cross-modal alignment accuracy while maintaining computational efficiency. SG-Mamba explicitly models modality-specific relations and long-range temporal context, achieving competitive performance on datasets like LRS3 and demonstrating robustness in cluttered environments.

    G-Mamba: Sparse Graph-Guided Mamba for Audio-Visual Speech Enhancement

    arXiv:2609.18009v1 Announce Type: cross Abstract: Lightweight audio-visual speech enhancement (AVSE) models face a critical trade-off between computational efficiency and cross-modal alignment accuracy. While simple concatenation lacks relational expressiveness, dense cross-atten…
