Abstract: Recent years, speech enhancement techniques in order to suppress noise and/or reverberation have been introduced into applications like hearing-aid. However, proposed speech enhancement techniques supporting selective binaural selective hearing cannot work in noisy reverberant environment. This paper aims at constructing speech enhancement supporting binaural selective hearing in noisy reverberant environment. Experiment I verifies whether Two–Stage Binaural Speech Enhancement with Wiener Filter (TS–BASE/WF) can suppress early reflection and late reverberation. Results show that TS–BASE/WF cannot suppress early refractions due to using a wiener filter. Cepstral mean subtraction (CMS) is used as front–end of TS–BASE/WF based on this result. Experiment II is carried out to show whether the modified method is superior to TS–BASE/WF in noisy reverberant environments. This result indicates that the modified method exceeds TS–BASE/WF.
