PROBLEM TO BE SOLVED: To make a singer correct the singing by watching the advice words, by marking the karaoke singing in every specific performance section, and displaying the advice words corresponding to the result of the marking during the performance of the prescribed performance sections, or immediately after the performance. SOLUTION: A voice signal processing unit 3 analyzes the frequency and the sound volume of an input singing voice signal, and generates the singing frequency data and the singing sound volume data. These data are compared with the frequency data and the sound volume data of a guide melody input from a CPU 10, to calcualte the difference data. The CPU 10 integrates the difference data. Further the rhythm difference data are concluded on the basis of a lag of a rise timing of the sound volume data, and the data is integrated. The integrated values are totalized at every one phrase of a karaoke song, to calculate a musical step point, a sound volume point and a rhythm point. The advice words on the point to be corrected, is displayed with the laughing- out face of an examiner, on the basis of the phrase point. |
