现有的语音-人脸跨模态关联学习方法在语义关联和监督信息方面仍然面临挑战，尚未充分考虑语音与人脸之间的语义信息交互。为解决这些问题，提出一种基于多模态共享网络的自监督关联学习方法。首先，将语音和人脸模态的特征映射到单位球面，构建一个公共的特征空间；接着，通过多模态共享网络的残差块来挖掘复杂的非线性数据关系，并利用其中权重共享的全连接层来增强语音与人脸特征向量之间的关联性；最后，使用K均值聚类算法生成的伪标签作为监督信号来指导度量学习，从而完成4种跨模态关联学习任务。实验结果表明，本文提出的方法在语音-人脸跨模态验证、匹配和检索任务上均取得了良好的效果，多项评价指标相较于现有基线方法提升1% ~ 4%的准确率。

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.
