• Authors: Peng Zhang, Jiaming Xu, Jing shi, Yunzhe Hao, Bo Xu
• Abstract summary: Speech separation aims to separate individual voice from an audio mixture of multiple simultaneous talkers. In our model, we use the face detector to detect the number of speakers in the scene and use visual information to avoid the permutation problem. Our proposed model is shown to outperform the state-of-the-art audio-only model and three audio-visual models.

• Abstract: Speech separation aims to separate individual voice from an audio mixture of multiple simultaneous talkers. Although audio-only approaches achieve satisfactory performance, they build on a strategy to handle the predefined conditions, limiting their application in the complex auditory scene. Towards the cocktail party problem, we propose a novel audio-visual speech separation model. In our model, we use the face detector to detect the number of speakers in the scene and use visual information to avoid the permutation problem. To improve our model's generalization ability to unknown speakers, we extract speech-related visual features from visual inputs explicitly by the adversarially disentangled method, and use this feature to assist speech separation. Besides, the time-domain approach is adopted, which could avoid the phase reconstruction problem existing in the time-frequency domain models. To compare our model's performance with other models, we create two benchmark datasets of 2-speaker mixture from GRID and TCDTIMIT audio-visual datasets. Through a series of experiments, our proposed model is shown to outperform the state-of-the-art audio-only model and three audio-visual models.
