DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a singing scoring system in a karaoke apparatus, and more particularly, to a singing scoring system capable of obtaining an appropriate scoring result even when a singer performs a unique singing method.

[0002]

2. Description of the Related Art A scoring function is well known as an additional function of a karaoke apparatus. This scoring function generates singing data indicating a singing state such as a pitch, a voice volume, or a tempo of a singer by sampling a singer's voice signal input from a microphone. The singing data is compared with scoring reference data such as main melody data in the karaoke data, and a predetermined score is given based on the comparison result to generate scoring data.

When the singing part is completed, the scores in the scoring data 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.

[0004]

In the conventional singing scoring system, the singing ability is determined based on the degree of coincidence of the singing state with a uniquely determined grading standard. The ability to match the singing state to a scoring criterion such as the main melody is determined to some extent for each singer. Therefore, the scoring results will always be the same. Therefore, there is a singing scoring method for providing a plurality of scoring modes so that the scoring results are not the same. This singing scoring system is disclosed in Japanese Patent Application Laid-Open No. 10-26992 (prior art example).
Discloses the technique. In this prior art example, the singer makes the grading standard strict or sweet according to the self-reported ability, so that even if the same person sings the same song, the scoring result differs according to the declared grading standard. .

[0005] However, singers vary in how they sing. This often comes from the singer's personality. For example, when singing a song of any genre, the singing style is like singing a song of a genre that you are good at unconsciously. Of course, some people deliberately sing in other genres. However, singing in other genres does not mean that the song itself sounds bad.
If you have enough singing skills, it sounds rather good.

In the conventional singing score system, the singing state is compared with a certain grading standard. And with his fidelity, he scored good and bad. The singing system using a plurality of grading modes also follows the "single" grading standard selected by the singer. Only the comparison accuracy in the scoring process is different. Therefore, no matter how good the listener may feel, the scoring result is not good if you use a unique singing method. It can be said that the superiority of the singing ability is appropriately evaluated as the faithful to the impression of the listener. Therefore, it is impossible at all with the conventional singing scoring system to appropriately evaluate a unique singing style.

An object of the present invention is to provide a singing scoring system that can appropriately evaluate a singing ability in accordance with a singer's individual singing style.

DETAILED 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 score system according to an embodiment of the present invention. The central control unit 11 is a computer main body including a CPU, a RAM, and a ROM, and controls the karaoke apparatus 1 by performing data communication with the peripheral components via a data bus 100 and a control bus 110.

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.

The karaoke apparatus 1 also has a scoring function for scoring the singing state of a person singing along with the karaoke music and outputting the scoring result. In addition, the scoring system can properly evaluate a singer's individual singing style. Hereinafter, the singing scoring function will be described.

=== Singing Scoring Function === <Activation of Singing Scoring Function> When the user wants to use the singing scoring function in the karaoke apparatus 1, a series of music pieces for performance reservation is transmitted from the remote control transmitter 17 or the operation panel 18. After the number, a predetermined operation key is pressed. Thereby, the operation command of the singing scoring function is transferred to the central control unit 11 via the operation control unit 19 and the data bus 100 together with the music number. Upon receiving the command, the central control unit 11 performs a performance reservation process on the assumption that the singing scoring function is activated when performing the performance process on the music. Of course, the singing scoring function may be activated by a user's billing procedure or the like. For example, a charging device is installed, and a singing scoring function is activated by inputting a predetermined fee to the charging 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 process of the music, the central control unit 11 monitors the section to be scored set in the karaoke data, that is, the beginning of the singing part. When the start point is detected, the singing scoring unit 30 which is a main part of the singing scoring function is instructed to start scoring processing.

<Processing by Singing Score Unit> FIG. 2 shows a schematic configuration of the singing score unit 30. The scoring processor 31 is a microcomputer dedicated to scoring processing including a CPU, a ROM, and a RAM. The AD converter 32 samples the singing voice input from the microphone 15 and converts it into digital data.

The scoring processor 31 executes various data processes according to a scoring processing program written in an internal ROM. Specifically, the singing status of the singer is sequentially extracted by analyzing the sampling data. Further, the accompaniment music generation data is received via the data bus 100, and the main melody (guide melody) data in the data is acquired as scoring reference data. Then, the scoring reference data and the singing data are compared one by one in order of performance time sequence, and a predetermined score is given according to the degree of coincidence. Then, scoring data including the score is generated and transferred to the central control unit 11 via the data bus 100.

What is important here is that the scoring processing program defines a plurality of different algorithms. The scoring process by the scoring processor 31 includes a process of executing processes according to the plurality of scoring algorithms in parallel to generate scoring data for each scoring algorithm in parallel. In the present embodiment, the scoring algorithms are defined for "pops", "rock", and "enka". Next, the features and outline of each scoring algorithm will be described.

<Characteristics and outline of each scoring algorithm> Each scoring algorithm defines singing characteristics (singing pitch, tempo, timing for singing each phrase, voice volume, etc.) to be emphasized in the singing data. That is, the musical characteristics (reference pitch, reference tempo, sounding timing of the first accompaniment sound of each phrase, volume, etc.) in the singing data corresponding to the singing characteristic to be emphasized are strictly scored as compared with other characteristics. Including such a process. Specifically, when scoring the feature, the reference point is set higher, and for the other features, the scoring reference is set lower. In the present embodiment, the features and outlines of each scoring algorithm according to the singing characteristics to be emphasized are as follows.

Pops A proper score is set for a vibrato-sung song. As a specific scoring process, singing interval data obtained by averaging intervals that change within the time between accompaniment sounds is included in the singing data, and is compared with the interval data in the scoring reference data. Also, the timing of singing out each phrase is not emphasized, so that even if the singer's pronunciation timing for the first accompaniment sound of each phrase is shifted, there is no significant penalty.

Rock system The importance of matching the singing timing of each phrase is emphasized.
That is, the emphasis is on whether or not the player frequently "shouts" (singing even short phrases). Specifically, a strict scoring process is performed on the temporal coincidence between the first accompaniment sound of each phrase and the sound generated by the singer.

Enka Entrance: It is important to make sure that a certain "reservation" (delay of the appropriate singing timing) is made in the singing part of each phrase, and whether the same phrase in Nos. 1 and 2 is sung by the same moderation. I do. As a specific scoring process,
During the music performance, the time difference between the first accompaniment sound of each phrase and the singer's singing start timing for that sound is sequentially extracted as `` time required '', and the score is calculated by comparing with the predetermined `` reference time ''. To go. The singing data extracted during the first singing is recorded as a singing history, and during the second singing, this singing history is added as new scoring reference data in addition to the normal scoring reference data. This gives 1
It is evaluated whether No. 2 and No. 2 were sung in the same moderation. In addition, since emphasis is placed on whether or not singing with a certain moderation, the scoring criterion is set relatively low except for comparing the pitch of the first accompaniment sound of each phrase with the singing pitch corresponding thereto.

<Display of Scoring Result> When the central control unit 11 detects the end of the scoring section such as the end of the singing part, the central control unit 11 aggregates the scoring data for each algorithm acquired up to that time, and obtains the total score for each algorithm. calculate. The total score of the algorithm having the highest score recorded among the total scores for each algorithm is displayed on the display 23 as a scoring result. FIG. 3 shows an example of the display.

=== Modification Example / Application Example === The display items of the scoring result may be displayed not only for the scoring algorithm in which the highest total score is recorded, but also for all scoring algorithms. Of course, the total score of the scoring algorithm selected by the user may be displayed.

In addition, the total score is recorded on a video CD or the like for a plurality of scenes including a content that reflects the scoring result (for example, an animation for announcing the success or failure of the audition) instead of a numerical value. The video data corresponding to the corresponding scene may be reproduced / displayed.

The contents of the scoring process in each scoring algorithm are not limited to those in the above-described embodiment, and singing characteristics to be emphasized can be freely set, and specific processing methods can be set as appropriate. Of course, the scoring algorithms processed in parallel are not limited to three.

[0026]

By performing the scoring process in parallel according to a plurality of scoring algorithms, it is possible to flexibly respond to the individual singing style of the singer and appropriately evaluate the singing ability. Therefore, it is possible to determine the superiority of the singing according to the impression received by the listener. Further, since a plurality of scoring results can be obtained for each scoring algorithm, the scoring results for any scoring algorithm can be displayed and output. Therefore, if a genre or the like that matches the singing style of the singer is displayed as the scoring result, the singer can objectively grasp the characteristics of his or her singing style.
