PROBLEM TO BE SOLVED: To provide a technique for generating evaluation data.SOLUTION: In evaluation data generation processing, a control unit generates information including a weight which becomes larger as a singing skill in a musical piece is more characteristic, as evaluation data, on the basis of an average value and standard deviation of a skill characteristic amount for each singing skill in one musical piece and a standard skill characteristic amount in a plurality of musical pieces (S280), generates reference data (S290), and stores it together with the evaluation data in a storage unit 14 of an information processing server 10 (S300). In a karaoke scoring processing, the control unit calculates a skill evaluation point by performing weighted calculation based on the evaluation data. As a result obtained by comparing pitch transition in a singing waveform with that in the reference data, the control unit calculates a higher reference evaluation point with a higher matching degree and calculates a total amount with the skill evaluation point as a total evaluation point. |
