Abstract(in Japanese) (See Japanese page)
Abstract(in English) A noise reduction system based on Adaptive Line Enhancer (ALE) and Noise Estimation Filter (NEF) 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. Then, the noise reduction system with less computation load has been also proposed. However, the system needs a pitch detector of sinusoidal noise. In this paper, a pitch period detection using the tap coefficients of the ALE for estimating the sinusoidal noise is proposed. The proposed method can detect the pitch period of sinusoidal noise superposed on speech.
