PROBLEM TO BE SOLVED: To perform performance evaluation much closer to user's sensation by determining the level of a degree of alignment of mutual performance from multilateral points in the case of performing duet performance.SOLUTION: An evaluation function 100 acquires singing voices from microphones 23A, 23B from respective singers by a signal acquisition part A111 and a signal acquisition part B113. An analysis part 103 analyzes the singing voice of each singer acquired by a signal acquisition part 101, and a detection part 121 detects the presence/absence or type of an evaluation object included in each input signal, and a specification part 123 specifies the content and timing of each evaluation object in the case of comparing each evaluation object included in each input signal on the basis of a detection result by the detection part 121. A comparison part 105 calculates and compares a difference between the pitches, volumes, vocal quality and techniques of a plurality of signers on the basis of the analysis result of the singing voice of each singer by the analysis part 103, and an evaluation part 107 calculates an evaluation value as an index of evaluation of a plurality of singing voices on the basis of a comparison result by the comparison part 105.SELECTED DRAWING: Figure 2 |
