| Abstract(in English) | This paper addresses a dereverberation method for improving speech recognition capability under reverberant environments. This method dereverberates speeches using the Spectral Subtraction (SS) method. According to the diffuse sound theory, subtraction coefficients of the SS method are calculated from a reverberation time. The proposed method can dereverberate speeches in various reverberant environments robustly without prior knowledge because it estimates reverberation times from speeches. Recognition experiments with JEIDA-JCSD (B-set) and CENSREC-4 show that the proposed method improves recognition rate in reverberant environments. |
