Abstract:
PROBLEM TO BE SOLVED: To provide a KARAOKE device capable of calculating an accurate and appropriate grading result. SOLUTION: When the singing aural signal is outputted from a selector 48 which selects singing or synthesizes aural signal V1 from a microphone 47a and a singing aural signal V2 from a microphone 47b, a data extract part 502a, 502b extract volume data and pitch data of the singing aural signal. When comparison parts 503a, 503b compare the volume data and the pitch data with reference guide melody data #A, #B, those comparison results are outputted as differential data Diffa, Diffb through filters 504a, 504b. When a synthetic part 50C calculates an average value of the differential data Diffa and Diffb, an evaluation part 50D calculates a grading result based on the synthesized differential data Diffc.
