Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a singing scoring system in a karaoke apparatus, and more specifically to a singing scoring system that can legitimately evaluate the singing ability in correspondence with ad lib singing.
[0002]
[Prior art]
The scoring function is well known as an incidental function of karaoke equipment. This scoring function extracts the pitch uttered by the singer by sampling the singer's voice signal input from the microphone. This pitch is compared with a reference pitch corresponding to the main melody in the karaoke data, and a score corresponding to the comparison result is assigned to each appropriate scoring section. Then, when the singing part is completed, the total score is calculated by summing up the scores. The total score is displayed as it is on the scoreboard or the display, or a video reflecting the total score such as a video including a predetermined message or predetermined expression content is output to the display.
[0003]
[Problems to be solved by the invention]
Some karaoke users have a fairly high level of singing ability. These people have techniques that make the venue more fun by singing more comfortably for the listener. For example, singing a melody that has a relationship between the main melody and a harmonic sound in an ad lib.
[0004]
In addition, there are various versions of the original songs of some karaoke songs, such as album version, single version, and live version, that intentionally change the vocal melody. A professional singer sings using different versions of the singing scene.
[0005]
However, no matter how comfortable it is for the listener and the excitement of the place, the traditional scoring function determines how the singer sings faithfully to the main melody, so if you sing in an ad-lib or a different version of the melody The scoring results are of course not good. Furthermore, when a user remembers a song that is a version different from that for karaoke, a person with inferior singing ability may obtain a good scoring result. It is hard to say that singing ability and expressiveness are properly evaluated.
[0006]
Then, this invention aims at providing the singing scoring system which can obtain an appropriate scoring result corresponding also to the song by an ad lib, and the song by a different version.
[0007]
[Means for Solving the Problems]
The present invention is characterized in that a karaoke apparatus that processes karaoke data of a specified karaoke piece of music to generate accompaniment music and outputs it to a speaker comprises the following means (1) to (6). is there.
(1) A means for sampling a singer's voice signal from a microphone and extracting a singer's vocal pitch (2) A means for obtaining a reference pitch corresponding to the main melody of the accompaniment music attached to the karaoke data ( 3) Means for acquiring a harmonic pitch in a relationship between the reference pitch and the harmonic pitch (4) The reference pitch and the harmonic pitch are sequentially compared with the utterance pitch, and the reference pitch and the harmonic pitch in the harmonic pitch are compared. Means for sequentially counting scores corresponding to the degree of coincidence between the pitch closest to the generated pitch and the utterance pitch (5) Means for calculating the total score by counting the scores based on a predetermined calculation method (6) Scoring result display means for outputting a scoring result corresponding to the total score to the display
In the second invention, the means for acquiring the harmonic pitch employs a pitch corresponding to a predetermined musical instrument performance part attached to the karaoke data as the harmonic pitch.
[0009]
Further, the singing scoring system in which the means for acquiring the harmonic pitch is acquired by generating the harmonic pitch based on the reference pitch is the third invention, and the harmonic pitch is used as dedicated data used only as a scoring reference. The singing scoring system prepared accompanying the karaoke data is the fourth invention.

DETAILED DESCRIPTION OF THE INVENTION
=== Basic configuration and operation of karaoke apparatus ===
FIG. 1 shows a block diagram of a karaoke apparatus employing a singing scoring system in an embodiment of the present invention. A central control unit 11 including a CPU, a RAM, and a ROM controls the karaoke apparatus 1 by performing data communication and various controls via a data bus 40 and a control bus 50 for each peripheral component.
[0011]
The hard disk device 12 stores a large number of karaoke data for generating accompaniment music and lyrics images of 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 extracted 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.
[0012]
On the other hand, the lyric rendering data in the karaoke data is transferred to the video RAM 20 in synchronism with the accompaniment music generation process, and the lyric image is sequentially developed into a bitmap. The video control unit 21 superimposes this lyric image on the background video output from the video CD player 22 and outputs it to the display 23.
[0013]
Moreover, the karaoke apparatus 1 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 appropriately evaluate the singing ability corresponding to singing by ad lib and singing by different versions. The scoring function will be described below.
[0014]
=== Operation of scoring function ===
When the user wants to use the singing scoring function in the karaoke apparatus 1, a predetermined operation key is pressed subsequently to a series of music numbers for performance reservation from the remote control transmitter 17 or the operation panel 18. Thereby, the operation command of the singing scoring function is transferred to the central control unit 11 through the operation control unit 19 and the data bus 40 together with the music number. In response to this command, the central control unit 11 performs a performance reservation process for activating the singing scoring function when performing the performance of the music. Of course, the singing scoring function may be activated by a charging procedure by the user. For example, a billing device is installed, and a singing scoring function is activated by inserting a predetermined fee into the billing device at an appropriate time, such as immediately before a musical piece to be scored is played or during the performance of a prelude.
[0015]
When the central control unit 11 starts the music performance process, the central control unit 11 monitors the start of a section (usually a singing part) to be scored set in the karaoke data. When this starting point is detected, the scoring unit 30 which is the main part of the singing scoring function is instructed to start scoring processing.
[0016]
The scoring unit 30 extracts the singing pitch by sampling and analyzing the singing voice input from the microphone 15. Furthermore, accompaniment music generation data is received via the data bus 40, and the pitch data of the main melody in this data is acquired as a reference pitch. Further, melody pitch data of a predetermined instrument part in the accompaniment music generation data is extracted as a harmonic pitch.
[0017]
Next, the reference pitch and the harmonic pitch are compared with the singing pitch. First, of the reference pitch and the harmonic pitch, the pitch closest to the singing pitch is employed as the scoring pitch. The scoring reference pitch and the singing pitch are compared one by one in order of performance based on a predetermined algorithm, and a predetermined score is given according to the degree of coincidence.
[0018]
FIG. 2 shows the relationship between the pitch coincidence and the score. When a certain singing pitch 100 is closest to a certain scoring reference pitch 200, the adjacent pitches 201 and 202 can be dissonant. Therefore, when the singing pitch 100 coincides with the scoring reference pitch 200, 100 points are set, and when the singing pitch is deviated from the intermediate points 203, 204 between the adjacent pitches 201, 202, 0 points are set. Then, the intermediate points 203 and 204 and the scoring reference pitch 200 are equally divided, and a score is given according to the position of the singing pitch 100. The scoring unit 30 sequentially sends the scoring data including this score onto the data bus 40.
[0019]
The central control unit 11 sequentially stores the scoring data in the internal RAM, and when the scoring section ends, the scoring data is totaled to calculate a total score. And this total score is displayed on the display 23 as a scoring result.
In the present embodiment, the scoring result is displayed as a total score. It is also possible to set up a dedicated scoreboard and display the total score there. In addition to setting a rank for each predetermined overall scoring range, a video with a plurality of cuts including content that reflects the scoring results (for example, an animation that announces the success or failure of an audition) was prepared and obtained. An appropriate video cut may be selected and displayed according to the rank corresponding to the total score.
[0020]
Note that one musical instrument part may be adopted as the harmonic pitch, or pitches corresponding to all musical instrument parts that are sounded simultaneously may be adopted. Moreover, the part employ | adopted as grading reference | standard pitch previously in karaoke data may be designated, and the scoring part 30 may make it acquire the pitch of the part.
[0021]
=== Others ===
In the above embodiment, a pitch corresponding to a predetermined musical instrument part in the karaoke data is adopted as the harmonic pitch, but a pitch corresponding to the harmonic pitch may be generated from the reference pitch of the main melody.
[0022]
Alternatively, dedicated data that is used only as a scoring standard describing the melody based on the harmonic pitch is prepared for each karaoke song, and when the scoring function is activated, the dedicated data for the corresponding harmonic pitch is read. Also good. If you want to activate the scoring function when playing a certain karaoke song, if this dedicated data is not prepared, only the pitch of the main melody is adopted as the scoring standard as usual, or from the harmonic pitch and reference pitch by the above-mentioned instrument part It is also possible to switch appropriately, such as by using a generated harmonic pitch.
[0023]
【The invention's effect】
In addition to the main melody of karaoke music, the melody based on the harmonious pitch is adopted as a reference for singing, so that an appropriate scoring result can be obtained corresponding to singing by ad lib or singing by different versions. Of course, it can also be applied to music of a genre that contains more ad-lib elements, such as rap music, which has conventionally been difficult to score properly.
[0024]
By adopting the pitch corresponding to the specified instrument part in the karaoke data as the harmonic pitch, an advanced scoring function can be achieved simply by acquiring the accompaniment music generation data in the karaoke data as a scoring pitch. .
[0025]
By generating a harmonic pitch based on a reference pitch, a pitch that accurately forms a chord with the main melody can be used as a scoring standard.
[0026]
By separately preparing data describing a melody composed of harmonic pitches accompanying karaoke data, it is possible to cope with cases where not all pitches in accompaniment music are composed of harmonic pitches.
