Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes reverberant speech enhancement (RSE) with deep auto encoder (DAE) based on harmonic structure. DAEs have been also investigated for RSE based on log power spectra. However, these methods are unable to accurately restore harmonics because it is difficult to optimize the DAE model. Therefore, we proposed an approach to RSE adopting DAE augmented with harmonic structure as input. In addition, we investigate reverberation robust F0 estimation using continuous spectral subtraction in order to accurately extract the harmonic structure. We evaluated the speech quality by PESQ. As a result, we confirmed an effectiveness of the proposed method.
