PROBLEM TO BE SOLVED: To provide technology capable of performing fair scoring, when singing (or performance) is scored. SOLUTION: Singing voice of a singer is collected by a microphone 15, and converted to an audio signal. A control section 11 of a Karaoke device 1 detects a pitch from the audio signal, and generates a singing pitch data SP. The control section 11 compares the singing pitch data SP with a reference pitch data RP, and scores singing according to difference of both. At this time, the control section 11 corrects a score result according to tempo control information so that scoring standard may become severe, as the tempo gets slower, when the singer changes the tempo of a music piece by using an operation section 14.
