Singing start point detecting means, singing end point detecting means, music singing time calculating means, equal dividing means, scoring means, section counting means, and section counting result display control means It is what.

  The singing start point detecting means is means for detecting the first singing grading timing in the singing reference data of the karaoke music for singing as a singing start point. The singing end point detecting means is means for detecting the last singing grading timing in the grading reference data as the singing end point.

  The music singing time calculating means is means for calculating the singing time of the karaoke music based on the detected singing start point and singing end point. The equal dividing means is means for equally dividing the calculated singing time to generate a predetermined number of totaling sections. The scoring means is a means for calculating the singing scoring value by comparing the singing of the karaoke music by the singer with the scoring reference data in units of time sufficiently smaller than the total section. The section total result display control means is a means for displaying the total result in the section total means for each total section.

  In the karaoke scoring system of the present invention, the singing start point and the singing end point are automatically detected from the karaoke music scoring reference data, and the singing time of the karaoke music is calculated. Then, the calculated singing time is equally divided to generate a predetermined number of counting sections, and the scoring results by the scoring means are totaled for each of the equally divided counting sections.

  That is, not only can the counting section be automatically divided, but also the singing time of karaoke songs excluding the intro part and ending part is equally divided into a predetermined number of counting sections. Are divided in the same manner. Therefore, there is no need to set segment division data for each karaoke piece, and the singing score result can be displayed in a layout common to all karaoke pieces. Furthermore, since processing is performed so as to exclude sections that do not clearly sing, such as an intro part and an ending part, the display space can be used effectively.
