The method includes obtaining an input spectrum by executing frequency analysis of the input speech signal by a specific frame length, obtaining an estimated noise spectrum by estimating the spectrum of the noise components, obtaining the spectral slope of the estimated noise spectrum, multiplying the estimated noise spectrum by a spectral subtraction coefficient determined by the spectral slope, obtaining a subtraction spectrum by subtracting the estimated noise spectrum multiplied with the spectral subtraction coefficient from the input spectrum, and obtaining a speech spectrum by clipping the subtraction spectrum. The method may further include correcting the speech spectrum by smoothing in at least one of frequency and time domains. In this way, a speech spectrum in which noise components have been suppressed can be obtained.

Abstract: Time series signals are recognized by extracting a multiplicity of candidate feature vectors characterizing an individual time series signal without fixing a boundary for the individual time series signal, and calculating similarity values for each of the multiplicity of candidate feature vectors and the reference patterns stored in the recognition dictionary, from which one reference pattern for which the similarity value is greater than a prescribed threshold value is selected as a recognition result.
