PROBLEM TO BE SOLVED: To enable presentation of an evaluation result that satisfies all users from beginners to advanced-level people.SOLUTION: In a karaoke device 10, a vocal adapter 16 detects a pitch from an output signal Sshowing a singing sound and outputs a result of the detection as a signal S. A CPU 17 uses the signal Sto individually score a point SCfor a singing section ZNwith low difficulty shown in difficulty reference data DD and a point SCfor a singing section ZNwith high difficulty shown therein. The CPU 17 determines an addition ratio RA of both points SCand SCin accordance with a level of the point SC, and specifies a value obtained by adding the points SCand SCat the ratio RA, as a total evaluation point SC. The signal Sis transmitted to a server device 30, and is used for updating the difficulty reference data DD. The updated difficulty reference data DD is transmitted to the karaoke device 10, and is used for subsequent singing evaluation. |
