| Abstract(in English) | This paper presents a computational model of co-modulation masking release (CMR) as a model of acoustic source segregation. Firstly, problems of two acoustic sources segregation are formulated, and a wavelet filterbank, whose analysing wavelet is a gammatone filter, is designed as an auditory filterbank. Next, a derivation method of three physical clues(amplitude envelope, phase, and phase difference between two acoustic sources of the auditory filter outputs) is introduced. In particular, input phase is derived from two of the four constraints proposed by Bregman. The experiment simulating CMR in this paper deals with the same experimental stimuli as used by Hall et al.. The results indicate that the proposed model is one of the computational models representing the CMR. Maximum amount of co-modulatin masking release is about 8 dB. |
