Abstract

Abstract

The current audiovisual speech separation model is essentially the simple splicing of video and audio features without fully considering the interrelationship of each modality, resulting in the underutilization of visual information and unsatisfactory separation effects. The article adequately considers the interconnection between visual features and audio features, adopts a multi-headed attention mechanism, and combines the Convolutional Time-domain audio separation Network (Conv-TasNet) and Dual-Path Recurrent Neural Network (DPRNN), the Multi-Head Attention Time Domain AudioVisual Speech Separation (MHATD-AVSS) model is proposed. The audio encoder and the visual encoder are used to obtain the audio features and the lip features of the video, and the multi-head attention mechanism is used to cross-modality fuse the audio features with the visual features to obtain the audiovisual fusion features, which are passed through the DPRNN separation network to obtain the separated speech of different speakers. The Perceptual Evaluation of Speech Quality (PESQ), Short-Time Objective Intelligibility (STOI), and Signal-to-Noise Ratio (SNR) evaluation metrics are used for experimental testing in the VoxCeleb2 dataset. The research shows that when separating the mixed speech of two, three, or four speakers, the SDR improvement of the method in this paper is above 1.87 dB and up to 2.29 dB compared with the traditional separation network. In summary, this article shows that the method can consider the phase information of the audio signal, better use the correlation between visual information and audio information, extract more accurate audio and video characteristics, and obtain better separation effects.
