Abstract (in Japanese) (See Japanese page) 
(in English) This study proposes a missing component restoration method for time-frequency masked speech spectrogram based on time-domain signal estimation.
Proposed method utilizes either or both cue of local relations in the spectrogram lead by redundancy of time-frequency domain representation, and cue of prior information for features of target speech in addition to global structure in the spectrogram based on low lank expression of observed spectrogram.
Effectiveness of proposed method is investigated in experimental evaluations using masked speech spectrograms for noise elimination.
