【Abstract】 Based on the principle of computational auditory scene analysis (CASA), a CASA speech separation algorithm was proposed by using oscillator neural network. One example is used to explain the processing and the coefficients in the proposed algorithm in detail. The first part of the proposed algorithms includes the auditory periphery processing and the processing of the segmentation oscillator neural network. The speech auditory perceptive segments can be given by the processing of this part in the proposed algorithm, and they will be used for the clustering and reconstructing processing in the next part of the proposed algorithm.更多还原
