摘要： A voice processing device includes a zone detection unit which detects a voice zone including a voice signal or a non-steady sound zone including a non-steady signal other than the voice signal from an input signal and a filter calculation unit that calculates a filter coefficient for maintaining the quality of the voice signal in the voice zone while suppressing the non-steady signal in the non-steady sound zone according to the detection result by the zone detection unit, in which the filter calculation unit calculates the filter coefficient by using a filter coefficient calculated in the non-steady sound zone for the voice zone and using a filter coefficient calculated in the voice zone for the non-steady sound zone. In one embodiment, a verification unit verifies a constraint condition of the filter coefficient based on whether the amount of suppression of the non-steady sound signal that would result from applying the filter to the sound signal is less than or equal to a threshold value.

摘要： A first signal of two signals to be compared for similarity is divided into small areas and one small area is selected for calculating the correlation with a second signal using a correlative method. Then, the quantity of translation, expansion rate and similarity in an area where the similarity, which is the square of the correlation value, reaches its maximum, are found. Values based on the similarity are integrated at a position represented by the quantity of translation and expansion rate. Similar processing is performed with respect to all the small areas, and at a peak where the maximum integral value of the similarity is obtained, its magnitude is compared with a threshold value to evaluate the similarity. The small area voted for that peak can be extracted.
