Zusammenfassung:	PURPOSE:To evaluate the singing ability of a user with high accuracy by performing processing by detecting a normal sound multiplex sound source or stereophonic sound source with a voice automatically as a sound source recorded on an optical disk that the user uses. CONSTITUTION:For the stereophonic sound source, a detecting means 18 and a signal switching means 11 select the output signal of an addition signal output means 9 and the signal of center localization of its output is doubly amplified. An accompaniment signal becomes 2 times, so the extraction accuracy of the frequency (interval) of the voice signal is improved. For the sound multiplex sound source, the output signal of a subtruction signal output means 10 is selected by the detecting means 18 and signal switching means 11 and the output is only a sound signal because input signals are nearly equal in level and phase relation, so that the extraction accuracy of the frequency (interval) is improved. Those signals are regarded as 1st sound signal. consequently, high-accuracy marking and evaluation are possible.
