Abstract:
A sound quality determination device includes an acquisition unit acquiring an input sound, a frequency distribution calculation unit calculating a frequency distribution of the input sound acquired by the acquisition unit, a tilt calculation unit calculating a tilt indicating a change in intensity of an overtone with respect to a frequency based on the frequency distribution calculated by the frequency distribution calculation unit, a tilt comparison unit comparing the tilt calculated by the tilt calculation unit and a threshold related to the tilt, and a determination unit determining based on a result of comparison by the tilt comparison unit whether the input sound has a predetermined sound quality.

Claim (Index 2):
The sound quality determination device according to  claim 1 , further comprising:\n an overtone ratio calculation unit calculating an overtone ratio indicating a ratio of a frequency of an overtone with respect to a frequency of a fundamental tone based on the frequency distribution calculated by the frequency distribution calculation unit; and an overtone ratio comparison unit comparing the overtone ratio calculated by the overtone ratio calculation unit and a threshold related to the overtone ratio, wherein the determination unit determines whether the input sound has the predetermined sound quality based on the result of comparison by the tilt comparison unit and a result of comparison by the overtone ratio comparison unit.
