Abstract

PROBLEM TO BE SOLVED: To properly mark also unique warbled singing or the like by totalizing normal points and inherent points and calculating total points. SOLUTION: A marking part 30 compares a reference interval with a vocal interal based on prescribed algorithm and sequentially sends normal point data to a data bus 40. In parallel with the marking, the marking part 30 sequentially transfers the vocal interval to a central control part 11 at its extraction timing. The marking data and the vocal interval are recorded in a RAM, and at the time of detecting the end of a first singing part, the history of recorded vocal intervals is allowed to correspond to performance time series as an interval route. The control part 11 detects the start of a 2nd singing part and transfers the interval route to the marking part 30 in accordance with the time series. In parallel with normal point marking processing, a vocal interval extracted at real time during the singing of the 2nd singing part is compared with the interval route based on the prescribed algorithm, prescribed points are marked and the inherent marking data and the normal marking data are sequentially transferred to the control part 11.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a singing scoring system for a karaoke apparatus, and more particularly, to a singing scoring system capable of appropriately evaluating a singing ability corresponding to a singing person's own singing method such as moderation.

[0002]

2. Description of the Related Art A scoring function is well known as an additional function of a karaoke apparatus. This scoring 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. Further, the timing of each sound of the main melody and the sound emitted by the singer are also compared. Then, a score according to the comparison result is given for each appropriate scoring section. When the singing part is completed, the scores are totaled to calculate a total score. The total score is displayed as it is on a scoreboard or a display as a score value as it is, 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]

A professional singer or the like has a technique of singing by making full use of a unique singing expression of moderation to give a more comfortable feeling to the listener. For example, the vocal timing is deliberately delayed by one tempo with respect to a certain performance sound, or a fist is given in enka or the like. Karaoke users often sing using this moderation technique in order to appeal their singing skills to the listeners or to enliven the venue.

However, in the conventional scoring method, the singing ability is determined based on how the singing voice follows the pitch of the main melody and the sounding timing. Therefore, no matter how good the singing expression is, if you sing with your own moderation, the scoring result will naturally deteriorate.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a singing scoring system which can obtain an appropriate scoring result even when singing a karaoke tune by a decorative and unique arrangement such as a singing method with a fist.

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. 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.

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 the singing ability in accordance with the singer's own moderation, such as singing with a fist. Hereinafter, the scoring function will be described.

=== Operation of Scoring Function === When the user wants to use the singing and scoring function with the karaoke apparatus 1, a predetermined number of music pieces for performance reservation are transmitted from the remote control transmitter 17 or the operation panel 18, followed by a predetermined number. Press the operation key. 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 40 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 music performance processing, the central control unit 11 monitors the section to be scored set in the karaoke data, ie, the beginning of the singing part. When this start point is detected, the scoring unit 3 which is the main part of the singing scoring function
0 is instructed to start the scoring process. In the present embodiment, the processing and control of the central control unit 11 and the scoring unit 30 are changed between the first and second singing parts of the music.

As a process common to all singing parts, the scoring unit 30 samples and analyzes the singing voice input from the microphone 15 to sequentially extract the vocal pitch of the singer. Further, the accompaniment music generation data is transferred to the data bus 40.
And the pitch data of the main melody in this data is acquired as a reference pitch. The reference pitch and the utterance pitch are compared one by one in the performance time series based on a predetermined algorithm, and a predetermined score is assigned in accordance with the degree of coincidence. Normal score data including this score (hereinafter referred to as a normal score) is obtained. The data is sequentially transmitted onto the data bus 40. The central control unit 11 sequentially receives the normal scoring data and sequentially stores the data in the internal RAM. Next, a scoring process executed only when the first singing part is performed will be described.

The scoring unit 30 performs a process of sequentially transferring the extracted utterance intervals to the central control unit 11 at the timing of extracting the utterance intervals in parallel with the process of comparing the extracted utterance intervals with the reference interval.
The central control unit 11 sequentially records the utterance intervals in the RAM. At this time, each utterance interval is stored in the internal RAM while adding time data for specifying the utterance time, such as the elapsed time from the start of the singing part. When the end of the first part of the singing part set in the karaoke data is detected, the transmission of the utterance pitch to the scoring unit 30 is stopped, and the history of the first utterance pitch recorded so far is recorded. It is associated with a performance time series as a pitch path. In other words, this pitch path is described as a melody corresponding to a singing style unique to the singer. Next, a description will be given of the scoring process executed when the second and subsequent singing parts are performed.

When detecting the beginning of the second singing part, the central control section 11 sequentially transfers the above-mentioned pitch path to the scoring section 30 in accordance with the time series. The scoring unit 30 compares the utterance pitch extracted in real time during the second singing with the pitch path based on a predetermined algorithm in parallel with the process of giving the normal score, and determines the pitch and utterance timing. A predetermined score is awarded according to the difference between. The unique scoring data including this score (hereinafter, unique score) and the normal scoring data are sequentially transferred to the central control unit 11.

When detecting the end of the scoring section such as the end of the singing part, the central control unit 11 counts up the normal score and the unique score obtained so far, and adds them at a predetermined ratio to calculate the total score. I do. Then, 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.

=== Others === In the above embodiment, the central control unit describes the pitch path by adding time data for specifying the utterance time to the utterance pitch received from the scoring unit. May be added to data indicating the utterance timing to the extracted utterance interval, and then transferred to the central control unit. Of course, the scoring unit may be provided with means for recording the utterance pitch or means for executing a process for describing the pitch path.

[0018]

According to the present invention, the graduation path when the first karaoke song is sung is recorded, and this path is compared with the singing state of the second and subsequent singing, so that an appropriate scoring result corresponding to the singer's own moderation is recorded. Can be obtained.
