Abstract(in English) A noise reduction system based on Adaptive Line Enhancer (ALE) and Inverse Filter has been proposed to reduce both wideband and sinusoidal noise in noisy speech. However, the noise reduction system uses several adaptive filters and thus the system cannot avoid increasing computation load. ALE for estimating the sinusoidal noise especially uses large numbers of taps in order to increase the estimation accuracy of the sinusoidal noise. In this paper, the noise reduction system with less computation load is proposed. The tap coefficients of the ALE have the peak by pitch period of sinusoidal noise. The proposed method takes advantages of the characteristics and decreases the number of taps.
