PROBLEM TO BE SOLVED: To make it possible to fairly evaluate the singing voices of respective parts in duet music and to obtain exact rating results by comparing the respective singing voice signals fetched from plural microphones with different reference values and to rate the respective singing voices by discrete singing ability based on the compared result. SOLUTION: Data extraction sections 502a, 502b extract the pitch data and sound volume data at every 50ms from the respective digitalized singing voice signals. Comparator sections 502a, 503b respectively compare the pitch data and sound volume data extracted from the respective singing voice signals and the pitch data and sound volume data of the guide melodies of the parts corresponding to the respective singing voices and rates the singing ability with respect to the respective singing voices. Namely, the comparator section 503 compare the singing voices from the microphone 17a and the guide melodies of main vocal parts, thereby executing the rating. On the other hand, the comparator section 503b compare the singing voices from the microphone 47b and the guide melodies of the chorus parts, thereby executing the rating. |
