SOUND DISCRIMINATION DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress a remaining echo component included in a feature amount.SOLUTION: A sound discriminating apparatus 100 includes: a first acoustic signal analyzing unit 103 configured to analyze a frequency spectrum of a first acoustic signal; and a feature extracting unit 101 configured to remove a frequency spectrum of the first acoustic signal from a third acoustic signal, which is obtained by suppressing an echo component of the first acoustic signal contained in a second acoustic signal, so as to extract the feature amount of a frequency spectrum of the third acoustic signal.
