Abstract

PROBLEM TO BE SOLVED: To obtain the scoring method which can obtain a proper scoring result in consideration of a range that a singer can not sing by totalizing scores by a specific calculating method which estimates scores of a specific range low once detecting the score distribution of the specific range being relatively lower than the score distributions of other ranges. SOLUTION: A scoring part 30 extracts a singing interval by sampling and analyzing a singing voice inputted from a microphone 15. Then a score distribution table wherein scores are made to correspond to all reference intervals included in a musical performance is generated. A central control part 11 investigates the score distribution table, and the control part when recognizing that mean scores above or below a certain interval are relatively lower than other mean scores by larger than a specific score difference specifies this range as a low-level range. This low-level range is excluded from objects to be scored, only the scores of other ranges are totalized, and the mean score are regarded as total score.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a singing scoring method in a karaoke apparatus having a scoring function, and more particularly to a singing scoring method in consideration of a range where a singer cannot speak.

[0002]

2. Description of the Related Art A singing and scoring function is well known as an additional function of a karaoke apparatus. The singing scoring method using this function extracts a pitch uttered by the singer by sampling the singer's voice signal input from the microphone. This interval is compared with a reference interval corresponding to the main melody in the karaoke data, and a score corresponding to the comparison result is given for each appropriate marking section. Then, when the singing part ends, the scores are totaled to calculate a total score. As the total score, the score value as it is is displayed on a scoreboard or a display, or a video reflecting the total score such as a video including a predetermined message or a predetermined expression content is output to the display.

[0003]

In the conventional singing scoring method, the vocal pitch of the singer and the reference pitch obtained from the karaoke data are compared quite strictly. However, unlike professional singers, karaoke users have a limited range in which they can speak. Therefore, despite having singing ability,
The scoring result may not be good because no bass or treble sound was output. In this case, it is difficult to say that the singing ability and the expressive ability are properly scored.

Certainly, the karaoke apparatus has a key control function for shifting the pitch of the performance of the karaoke music in accordance with the singer's utterable range. However, it is difficult to set the key control function unless the singer himself or herself sufficiently grasps the utterable range. Most of the time, I try to set the key value that works for me.

Accordingly, an object of the present invention is to provide a scoring method capable of obtaining an appropriate scoring result in consideration of a sound range in which a singer cannot speak.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS === Basic Configuration and Operation of Karaoke Apparatus === FIG. 1 is a block diagram of a karaoke apparatus employing a singing scoring method according to an embodiment of the present invention. CPU, R inside
A central control unit 11 including an AM and a ROM controls the karaoke apparatus 1 by performing data communication and various controls on the peripheral components via a data bus 40 and a control bus 50.

The hard disk device 12 stores a large number of karaoke data for generating accompaniment music and lyrics images of the karaoke music. When the central control unit 11 receives a request input from the remote control transmitter 17 or the operation panel 18 via the operation control unit 19, the central control unit 11 sequentially processes the corresponding karaoke data according to the request input order. That is, karaoke data corresponding to the requested music is retrieved from the hard disk device 12, and accompaniment music generation data (such as MIDI data) is transferred to the synthesizer 13 to generate accompaniment music. The accompaniment music is mixed with the singing voice input from the microphone 15 by the mixing amplifier 14 and output to the speaker 16.

On the other hand, the lyrics rendering data in the karaoke data is transferred to the video RAM 20 in synchronization with the accompaniment music generation processing, and the lyrics images are sequentially developed into bitmaps. The video control unit 21 superimposes the lyrics image on the background video output from the video CD player 22 and outputs the superimposed lyrics image to the display 23.

Further, the karaoke apparatus 1 has a singing scoring function for scoring the singing state of a person singing along with the karaoke music and outputting the scoring result. Moreover, a scoring result can be obtained in consideration of a range in which the singer cannot speak. Hereinafter, the singing scoring function will be described.

=== Operation of Singing Grading Function === When the user wants to use the singing scoring function with the karaoke apparatus 1, a predetermined number of music pieces for reservation of performance are given from the remote control transmitter 17 or the operation panel 18 after a series of music numbers. Press the operation key of. Thereby, the music number to which the code indicating the operation instruction of the singing scoring function is added is transferred to the central control unit 11 via the operation control unit 19 and the data bus 40. When performing the music performance processing, the central control unit 11 performs the performance reservation processing on the assumption that the singing scoring function is activated. Of course, the singing scoring function may be activated by a user's billing procedure or the like. For example, a billing device is installed, and a singing scoring function is activated by inputting a predetermined fee to the billing device at an appropriate time, such as immediately before a musical piece to be scored is played or during a prelude.

When starting the performance processing of the music, the central control unit 11 monitors the beginning of the section (usually a singing part) to be scored set in the karaoke data. When the start point is detected, the start of the scoring process is instructed to the scoring unit 30 which is a main part of the singing scoring function.

The scoring unit 30 extracts a singing pitch by sampling and analyzing the singing voice input from the microphone 15. Further, accompaniment music generation data is received via the data bus 40, and the pitch data in the data is acquired as a reference pitch. Then, these musical intervals are compared one by one in order of performance time series based on a predetermined algorithm, and a predetermined score is given according to the degree of coincidence. The scoring data is generated by associating the score with the reference pitch acquired at that time. The scoring data is sequentially transferred to the central control unit 11 via the data bus 40.

Upon receiving the transferred scoring data, the central control unit 11 stores it in the internal RAM. When detecting the end point of the scoring section in the karaoke music, the scoring unit 30
To stop generating scoring data. Then, the scoring data accumulated in the RAM during the scoring section is totaled, and a score distribution table is created in which scores are associated with every reference interval included in the performance. FIG. 2 shows a schematic diagram of the score distribution table. The average score for each reference interval is shown.

The central control unit 11 examines the score distribution table and determines that the average score above a certain pitch or below the pitch is relatively low with a score difference of a predetermined value or more from the other average scores. If recognized, this range is designated as a low-level range. Furthermore, this low-level range is excluded from the scoring target, and only the scores in other ranges are totaled, and the average score is used as the total score. The total score is displayed on the display 23 as a scoring result. In this embodiment, the scoring result is displayed as a numerical value of the total score. It is also possible to set up a dedicated scoreboard etc. and display the total score there. In addition, a rank is set for each predetermined total score range, and a plurality of cut images (for example, animations for announcing the success or failure of an audition) including contents reflecting the scoring result are prepared on a video CD or the like. An appropriate video cut may be selected and displayed according to the rank corresponding to the total score.

If the score is low in the middle part of the performance range, such as a certain pitch or more and a certain pitch or less, the singing ability is simply inferior and this pitch band is not set as a low-level range, and the score is left as it is. Has adopted.

=== Others === In the above embodiment, the score in the low-level range is excluded from the scoring target and the total score is calculated. However, a predetermined correction coefficient is applied to the score in the low-level range. The score of this range may be inflated by multiplying.

In addition to the total score in consideration of the score in the low-level range, a normal total score is calculated by directly using the score in the entire range, and two scoring results corresponding to these two total scores are displayed. You may.

Also, the lower level range is higher than or equal to any pitch (or lower).
It is also possible to display what it is. The performance range of the karaoke song and the range in which the singer could utter may also be displayed.

Further, it is also possible to obtain a range in which the singer can utter from the score distribution table, set an optimum key so that the reference pitch of the karaoke music falls within the range, and display the key.

The setting of the low-level sound range can be made variable. That is, a plurality of low-level sound ranges are set by gradually reducing the average score difference from other sound ranges when the low-level sound range is designated. Thereby, a plurality of total scores may be calculated, and the scoring result may be displayed for each of the total scores. Of course, it is also possible to display the set value of the low-level sound range corresponding to each scoring result together.

[0026]

According to the present invention, the singing ability can be scored in consideration of the range in which the singer cannot speak. Therefore, singing ability and expression ability can be evaluated appropriately.

Also, by displaying the scoring result in consideration of the vocal range of the singer and the scoring result corresponding to the normal total score using the scores in the entire pitch range, there is a range in which the vocal can not be uttered up to now. Therefore, it is possible to grasp the score that had been lost.

By displaying the sound range that cannot be uttered, it is possible to grasp the sound range that can be uttered. In addition, it is possible to give a guide to the key setting.

By finding the optimum key setting value from the scoring result and displaying it, the next time the same song is sung,
Karaoke music can be played with optimal key settings without trial and error.

By making the setting of the low-range sound range variable, a scoring result corresponding to each setting can be displayed. For this reason, the singer can grasp the vocal range in which the singer can speak in detail, and also encourages the singer to make an effort to expand his vocal range.
