Hereinafter, a song correction service providing method according to an exemplary embodiment of the present invention will be described with reference to FIG. 2. 2 is a data flow diagram of a song correction service providing method according to an embodiment of the present invention.

In the home or karaoke where the karaoke device is installed, the user accesses the ARS 20 by using the subscriber's mobile phone 10 and requests a song correction service (S201).

When the ARS 20 receives a song correction service request, the ARS 20 provides the user's mobile phone number to the song information server 30 to request user authentication, and if the user is a subscriber, provides the song list information to the subscriber's mobile phone 10. (S202). The song list is categorized by each song type (by genre, singer, title) so that subscribers can easily find a desired song.

When a list of songs is displayed on the subscriber's mobile phone 10, the subscriber selects a desired song from the list of songs (S203) and informs the ARS 20 of this (S204). Then, the ARS 20 transmits the song selection information (including the identification information for the specific song) received from the subscriber cell phone 10 to the song information server 30 (S205).

When the song information server 30 confirms the song selected by the user with the received song selection information, the song providing server 40 reads the song information (song file) of the singer for the song selected by the user from the sound source DB 31. Provided to (S206).

The song providing server 40 plays the song information of the singer in accordance with the subscriber's song start request (S207), and provides the reproduced music to the subscriber mobile phone 10 through the ARS 20 (S208, S209), At the same time provided to the analysis server 50 (S210).

The reason why the song providing server 40 reproduces the singer's song information in response to the subscriber's request is to reproduce the music provided to the subscriber's mobile phone 10 through the ARS 20 with the accompaniment music output from the karaoke device. Because. Therefore, the ARS 20 performs a function of informing the subscriber of the voice information requesting the time of playing the song, and in response, when the subscriber notifies the playing time by pressing a specific button of the keypad according to the guidance from the ARS 20, the song providing server 40 reproduces the song of the singer in accordance with the reproduction start signal received from the ARS 20.

Here, the reason why the song providing server 40 simultaneously provides the singer's song played to the subscriber's mobile phone 10 and the analysis server 50 is because of the subscriber's singing song information acquired from the subscriber's mobile phone 10 and the song information. This is to allow the reproduced music of the singer to be compared with to be synchronized. In general, since the subscriber sings the song in synchronization with the reproduced song information, the subscriber's singing song information provided to the analysis server 50 through the ARS 20 is determined by the singer provided by the song providing server 40. Almost simultaneously with the song information will be provided to the analysis server 50.

That is, when the singer's song flows out to the subscriber's mobile phone 10 by the process (SS209), the subscriber listens to the mobile phone 10 by using his or her hands free and sings in accordance with the accompaniment of the karaoke device (S211). Then, the subscriber's song information along with the singer's playing music is received by the analysis server 50 through the ARS 20 (S212, S213). Thus, the song information of the subscriber received by the analysis server 50 through the ARS 20 is received at the same time as the song information of the reproduced singer provided by the song providing server 40. In this case, the analysis server 50 stores the song information of the received subscriber, so that it can be provided later when requested by the subscriber or the administrator. The storage of the song information according to the subscriber may be performed by the song providing server 40 or the song information server 30 on behalf of the analysis server 50.

On the other hand, there are two types of song information. The first is the form of listening, that is, a mix of accompaniment and lyrics, and only the lyrics. In order to best meet the purpose of the present invention, it is preferable to provide only the lyrics part of the singer, but in some cases it may not. The process of providing only the lyrics part of the singer will be described below with reference to FIG. 3.

When the analysis server 50 receives the song information of the subscriber along with the song information of the singer from the ARS 20 and the song information of the singer from the song providing server 40, the analysis server 50 compares the received song information (S214), and analyzes the analysis information as a result of the comparison. To generate (S215).

The analysis information includes information about a pitch error part and a beat error part, and may also include scoring result information. The analysis operation in the analysis server 50 will be described in more detail with reference to FIGS. 4 and 5.

When the process (S401) occurs, the analysis server 50 extracts only the lyrics data from the song information of the subscriber (S402). Since the song information of the singer is composed only of the lyrics information, the lyrics data extraction process is not necessary.

The analysis server 50 checks the frequency value for each of the lyrics data of the subscriber and the lyrics data of the mantissa received at the same time point (S403), and compares (S404). The frequency value depends on the degree of the high and low of the sound, that is, the scale. Therefore, by comparing the frequency value, it is possible to know whether the subscriber is singing the singer's song at the correct pitch.

If the frequency value of the corresponding lyrics sung by the subscriber and the frequency value of the corresponding lyrics sung by the subscriber are not the same (S405), the corresponding lyrics are classified into pitch error lyrics (S406), and the pitch error lyrics are color-coded. (For example, it is displayed in blue) and stored as analysis information (S407).

Hereinafter, a measurement error analysis process according to the present invention will be described with reference to FIG. 5. 5 is a flowchart illustrating a process of extracting a beat error part from song information acquired from a user according to the present invention.

Then, the analysis server 50 compares the duration of the identified frequency values (S504).

As a result of the comparison, if the duration of the frequency value of the lyrics sung by the subscriber and the duration of the frequency value of the lyrics sung by the singer are different (S505), the analysis server 50 classifies the lyrics as a beat error lyrics ( S506), the beat error lyrics are displayed in a specific color (for example, red) and stored as analysis information (S507).

In the present invention, when a beat and a pitch error occur in the same measure, it is preferable to display it in a separate color (for example, yellow).

The analysis server 50 performs the pitch error analysis and beat error analysis at the same time, scoring based on the degree of the beat or / and pitch error lyrics generated and stores it as analysis information.

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not intended to limit the present invention. In addition, it is a matter of course that various modifications and variations are possible without departing from the scope of the technical idea of the present invention by anyone having ordinary skill in the art.

The present invention provides a song portion of a singer who sang the song, which can be synchronized with the accompaniment provided by the karaoke device, thereby making it easier to sing the song than to see the lyrics and sing along with the accompaniment. Analyze the information so that you can find out what is wrong. In addition, the present invention provides a scoring score in addition to the analysis information and can enjoy the game through competition with others.
