Affective computing serves as the fundamental technology and a crucial prerequisite for attaining naturalized and anthropomorphic human–computer interaction. Nevertheless, the expression of emotion is complex and multi-dimensional, posing significant challenges for multimodal emotion recognition due to the heterogeneity gap among distinct modalities. To tackle this issue, we propose a novel approach named modality emotion semantic correlation analysis (MESCA), which enhances multimodal affective semantic consistency by leveraging modality correlation learning to achieve multimodal information complementation. Specifically, we first design a modal-pair correlation module that calculates emotion semantic consistency across text, audio and video information. This module contributes to a comprehensive understanding of the emotional state by fusing complementary semantic information and assists in mitigating redundancy in pairwise interaction methods. Next, we introduce structural re-parameterization technology that transforms the multi-branch training structure into a single-branch inference structure to solve the problem of excessive computational expense, thereby facilitating a more efficient and effective recognition process. Additionally, the proposed model is verified on two public datasets, IEMOCAP and CMU-MOSEI. Compared to baseline methods, MESCA significantly enhances efficiency while maintaining prediction accuracy on IEMOCAP, and outperforms on both efficiency and accuracy on CMU-MOSEI.
