Abstract (in Japanese) (See Japanese page) 
(in English) In the public transportation system such as subway, usually it is so noisy that passengers even cannot hear the announcement like what the next stop and which door would be opened clearly. To solve this problem, Obayashi, et. al proposed a method that extends the frequency of the voice. However, it was difficult to get good results for some consonants with the proposed method. Therefore, in this study, we newly propose a method to investigate and improve perceive consonants. First of all, we analyzed some announcements taken inside a subway, and compared the consonants by analyzing power spectra of obtained announcement. As a result, we set up a hypothesis “Emphasizing the whole band of phoneme is the key point of effectiveness”. Then, we carried out a hearing experiment in which the person under tested hear the obtained noisy voices and ask them what they heard. From the experiment, we found out that the recognition of consonants comparing with the preceding study has been improved about 10% under keeping the voice quality clearly. As the future subject, we will go over more improvement of each consonant by using suppressing steady-state portions.
