PROBLEM TO BE SOLVED: To extract a voice feature quantity capable of improving noise resistance performance of voice recognition.;SOLUTION: A voice feature quantity extraction device includes a segmentation section 101 and a calculation section 106. The segmentation section 101 generates one of a unit voice signal 11 and a plurality of sub-band unit voice signals by segmenting a voice waveform over predetermined time length for each unit time from one of an input voice signal 10 and a plurality of sub-band input voice signals obtained by extracting a signal component of a plurality of frequency bands from the input voice signal 10. The calculation section 106 obtains a voice feature quantity 16 by calculating one of average time of the unit voice signal 11 and each of average times of the plurality of sub-band unit voice signals in each of the plurality of frequency bands.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
