Abstract

Existing voice-face cross-modal association learning methods still face challenges in semantic correlation and supervised information, and have not yet fully considered the semantic information interaction between voice and face. To solve these problems, a self-supervised association learning method based on a multi-modal shared network was proposed. Firstly, the voice and face features were mapped into the unit sphere to establish a shared feature space. Secondly, complex nonlinear data relationships were explored using the residual block of the multi-modal shared network, while a weight-sharing fully connected layer was utilized to enhance the correlation between voice and face. Finally, pseudo-labels, generated by the K-means clustering algorithm, were utilized as supervised signals, guiding the metric learning process to accomplish the four cross-modal association learning tasks. Experimental results show that the method proposed in this paper achieves favorable outcomes in voice-face cross-modal verification, matching, and retrieval tasks, and several evaluation metrics improve 1% ~ 4% accuracy compared with existing baseline methods.
