Abstract(in Japanese) (See Japanese page)
Abstract(in English) On the modulation spectral domain, speech components and noise components can be separated by their modulation spectral bands. Although conventional methods extract speech components using band-pass filtering on running spectrum, those extractions are affected by limitations of filtering such as stability, filter steepness, etc.. Instead of it, we present Modulation Spectral Control. It realizes the feature extraction of modulation spectral bands with weighting factor on modulation spectral domain and is free from those limitations. The combination of it and Spectral Subtraction shows outstanding performance and flexibility for the variety of noise corruptions.
