SOUND ANALYSIS DEVICE, SOUND ANALYSIS SYSTEM AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a sound analysis device capable of determining an intention of a device wearer from a type of sound acquired with a microphone when the acquired sound is assumed not to be a voice.SOLUTION: A terminal device 10 comprises: microphones 11 and 12 that are arranged at positions at different distances from a wearer's mouth for acquiring sound; a sound pressure comparison part for comparing sound pressure of the sound acquired by the microphone 11 closer to the wearer's mouth with that of the sound acquired by the microphone 12 farther from the wearer's mouth; and a determination part for determining whether or not the acquired sound coincides with a predetermined type when a result of the comparison by the sound pressure part shows that a proportion of the sound pressure of the sound acquired by sound acquisition means closer to the wearer's mouth to that of the sound acquired by the sound acquisition means farther to the wearer's mouth is greater than a predetermined value.
