摘要:
A voice analyzer includes a voice information acquiring unit that acquires information about voices acquired by a first voice acquiring unit which acquires the voice and is worn by a first wearer and a second voice acquiring unit which acquires the voice and is worn by a second wearer from each of the wearers, and a distance calculation unit that calculates a distance between the first wearer and the second wearer on the basis of (a) speaker identification information, which is information for determining whether the voice acquired by the first voice acquiring unit and the voice which is the same as that acquired by the first voice acquiring unit and is acquired by the second voice acquiring unit are spoken by the wearers or other persons, and (b) a phase difference between sound waves with plural frequencies included in the voices.
