Self-supervised learning (SSL) models for speaker verifica- tion (SV) have gained
significant attention in recent years. However, existing SSL-based SV systems
often struggle to capture local temporal dependencies and generalize across
different tasks. In this paper, we pro- pose context-aware multi-head factorized
attentive pooling (CA-MHFA), a lightweight framework that incorporates contextual
information from surrounding frames. CA-MHFA leverages grouped, learnable queries
to effectively model contextual dependencies while maintaining efficiency by
sharing keys and values across groups. Experimental results on the VoxCeleb
dataset show that CA-MHFA achieves EERs of 0.42%, 0.48%, and 0.96% on Vox1-O,
Vox1-E, and Vox1-H, respectively, outperforming complex models like WavLM-TDNN
with fewer parameters and faster convergence. Additionally, CA-MHFA demonstrates
strong generalization across multiple SSL models and tasks, including emotion
recognition and anti-spoofing, highlighting its robustness and versatility.
