PHONATION EVALUATION DEVICE, PHONATION EVALUATION METHOD AND PROGRAM

PROBLEM TO BE SOLVED: To provide a technique for objectively evaluating a phonation method mixing a normal voice with a falsetto voice.SOLUTION: The device includes: an evaluation unit 52 which learns from learning data based on a fundamental wave and a plurality of harmonic waves in first sound information which is obtained in advance and corresponds to a normal voice of at least one of a subject and a sound producing person other than the subject, and second sound information corresponding to a falsetto voice; and an extraction unit 60 for extracting the fundamental wave and the plurality of harmonic waves in sound information input by a microphone 24. The device inputs evaluation data based on the fundamental wave and the plurality of harmonic waves extracted by the extraction unit 60, in a computer expression 70, and calculates a value output by the computer expression 70 as a first fusion rate of the normal voice and the falsetto voice in the sound information, thereby enabling a person to more easily understand the percentage of mixture of a normal voice and a falsetto voice in a voice uttered by the person by practical processing.
