| 抄録: | Many methods of enhancing speech have recently been proposed to suppress the effects of noise or reverberation. Although most of these have aimed to only enhance noisy speech or reverberant speech, they have not simultaneously been able to enhance noisy reverberant speech. As MTF canbe used to predict the loss of speech intelligibility due to noise and reverberation, it may be possible to simultaneously suppress the effects of deterioration due to noise and reverberation,by utilizing MTF-based processing. No methods of suppressing noise based on the MTF concept have yet been considered while a method of dereverberation based on the MTF concept has already been proposed. We propose a method ofrestoring temporal power envelopes from noisy speech based on MTF. The proposed method suppresses noise by restoring smeared MTF. We carried out simulations on suppressingnoise in noisy speech to objectively evaluate the model we propose. The results obtained from evaluating the method demonstrated that the proposed approach could effectively suppress noise. |
