The singing ability determination unit 25 includes a frequency analysis circuit for the main melody signal, a frequency analysis circuit for the singing voice signal, and an integration circuit for comparing the frequency analysis output of each frequency analysis circuit and integrating the difference between the two. As shown in FIG. 4, the integration circuit integrates the absolute value of the difference between the frequency of the main melody signal and the frequency of the singing signal (the deviation from the frequency of the main melody).

Here, the singing ability judging unit 25 determines, based on the above-described second judgment criterion, that the larger the difference between the frequency of the main melody signal and the frequency of the singing voice of the singer is, the more the period in which those frequencies are shifted. The longer the is, the larger the deduction target.

The third criterion is to evaluate a point in which a change in frequency (pitch) in time series is greatly different. The singing ability determination unit 25 integrates the absolute value of the difference between the differential output of the main melody signal and the differential output of each of the differentiating circuits. It has an integrating circuit that performs Then, as shown in FIG.
The absolute value of the difference between the time derivative signal of the frequency of the main melody and the time derivative signal of the frequency of the singing signal is integrated.

The singing ability judging section 25 does not directly deduct points for frequency (pitch) deviation based on the third judgment criterion described above, but obtains a time series of the frequency of the main melody and the frequency of the singer's singing voice. The change of the waveform (waveform) is the target of deduction.
