PROBLEM TO BE SOLVED: To provide technology by which, when scoring singing (or performance), it is more suited to human audible sense. 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 for each note, and scores singing for each note according to difference of both. When the singing pitch data SP are shifted to a sharp side from the reference pitch data RP (that is, when the singing pitch data SP are higher than the reference pitch data RP), it is scored with stricter scoring criteria, than when the singing pitch data SP is shifted to a flat side (that is, when the singing pitch data SP are lower than the reference pitch data RP).
