Abstract (in Japanese) (See Japanese page) 
(in English) Although the field of speech enhancement has been extensively studied around the world, phase tends to be neglected compared to amplitude and frequency among the basic quantities handled in speech signal processing. This is because it was believed that the contribution of phase to speech quality was small, based on the perception that human hearing is insensitive to changes in phase. However, with the development of speech signal processing, the importance of phase to speech quality has become clear. In this paper, we introduce the capsule structure of the Capsule Network, which has shown excellent performance in the field of image recognition in recent years, to the speech enhancement network, and attempt to improve the performance of the speech enhancement network and the naturalness of speech by constructing a speech enhancement model that also focuses on phase information.
