Abstract
A score evaluation display device for an electronic song accompaniment apparatus has an audio signal processing unit to evaluate a user's singing. A sampling processor samples the difference between an input song signal from a microphone and reference song signal, a volume deference detector detects a voltage difference between these two signals, a rhythm difference detector detects the difference in rhythm between these two signals, and an adder sums the outputs of the volume difference detector and the rhythm difference detector, thereby producing a finally evaluated score. Accordingly, a more reliable and accurate evaluation can be performed for a user's singing, based on the difference between the microphone's input song signal and the reference song signal.
