Abstract: A speech enhancement apparatus and method and a computer-readable recording medium having a program recorded thereon execute a speech enhancement method. The speech enhancement apparatus includes a spectrum subtraction unit generating a subtracted spectrum by subtracting an estimated noise spectrum from a received speech spectrum, a correction function modeling unit generating a correction function to minimize a noise spectrum using variation of a noise spectrum included in training data, and a spectrum correction unit generating a corrected spectrum by correcting the subtracted spectrum using the correction function.

Abstract: A pitch detection method and apparatus, the pitch detection apparatus includes: a data rearrangement unit which rearranges voice data on the basis of a center peak of the voice data included in a single frame; a decomposition unit which decomposes rearranged voice data into even symmetrical components on the basis of a center peak; a pitch determination unit which obtains a segment correlation value between a reference point and at least one or more local peaks in relation to even symmetrical components, and determines the location of a local peak corresponding to a maximum segment correlation value among the obtained segment correlation values, as a pitch period.

Abstract: An apparatus, method, and medium for detecting a voiced sound and an unvoiced sound. The apparatus includes a blocking unit for dividing an input signal into block units; a parameter calculator for calculating a first parameter to determine the voiced sound and a second parameter to determine the unvoiced sound by using a slope and spectral flatness measure (SFM) of a mel-scaled filter bank spectrum of an input signal existing in a block; and a determiner for determining a voiced sound zone and an unvoiced sound zone in the block by comparing the first and second parameters to predetermined threshold values.
