Musical Noise Reduction of Spectral Subtraction for Speech Enhancement
Masaru Fujieda, Takashi Yazu (OKI) EA2012-42
Abstract (in Japanese) (See Japanese page) 
(in English) In this report, an approach to reduce musical noise of spectral subtraction (SS) for speech enhancement is described. We propose a novel method reducing musical noise to suppress isolated gain arising on spectral gain as isolated frequency components. In the method, adaptive control of the amount of noise reduction based on a posteriori SNR and temporally-smoothed spectral gain curb the generation of isolated gain. The simulation with steady or non-steady additive noise shows that musical noise is almost-perfectly suppressed by the proposed method applying for SS method and Wiener filter.
