Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we study a structure of a deep neural network for speech enhancement.In speech enhancement, it is a big issue to suppress the noise in the silent interval and maintain a spectral envelope in the voiced interval, simultaneously. Because of a large variability of the amplitude spectrum, which is one of the features, and the complexity of the regression problems, the network has an under-fitting and then the speech quality is degraded. This paper, thus, relaxes the complexity of the problem by constraining a solution space to optimize an spectral gain of speech enhancement. Additionally, this paper tries to improve the speech enhancement performance by designing a loss function appropriately according to the distribution of the speech spectrum.
