<P>PROBLEM TO BE SOLVED: To provide a karaoke device capable of evaluating inflected singing. <P>SOLUTION: The karaoke device can detect the intensity of singing by a harmonic ratio which is a level ratio of a total level of frequencies f1, f2, and so on of harmonic components to a level of a fundamental frequency f0 with respect to a singing voice of a singer. The karaoke device can evaluate the degree of inflection of singing on the basis of inflection evaluation data showing the degree of variation in intensity of singing, so that evaluation of inflection of singing can be added to a score result of singing of the singer. Further, inflection of singing is evaluated on the basis of a frequency distribution of volume levels of the singing voice, namely, voice quality, so that evaluation independent of volume levels of singing is possible. <P>COPYRIGHT: (C)2013,JPO&INPIT |
