When a certain song is selected, the music determination unit 100 determines whether or not there is a song having the same structure as the certain song but different versions with different reference data.

As described above, songs of different versions have the same composition as a certain song, but have different reference data. "The composition of the music is the same" means that there is no clear difference in the composition of the music. For example, even if a part of the accompaniment data is slightly different, or if the instrument composition, pitch, rhythm, etc. are slightly changed, it can be said that the composition of the music is the same. Further, since the songs having different versions have different song IDs and attribute information, the karaoke device 1 recognizes them as different songs. On the other hand, the lyrics data and the performance section data are the same.

In the determination of whether or not there are songs of different versions, for example, the song determination unit 100 searches for a song having the same song name as a selected song, and if there is a song with the same song name, the searched song is found. This is done by comparing the lyrics data of a song with the lyrics data of a certain song.

For example, as in the above example, it is assumed that the reference data acquisition unit 200 has acquired the reference data of the music X'and the music X'. Further, it is assumed that the music X has "No. 1", "No. 2", and "No. 3" as predetermined performance sections.

In this case, the scoring value determination unit 300 uses the singing voice data obtained based on the first karaoke singing as the reference data of the music X and the reference of the music X'when the first karaoke performance of the music X is completed. Compare with each of the data and the reference data of the music X ″. The scoring value determination unit 300 outputs the highest scoring value (for example, the scoring value based on the reference data of the music X) among the comparison results to the presentation unit 400. Similarly, when the karaoke performance of the second (third) of the music X is completed, the scoring value determination unit 300 uses the singing voice data obtained based on the karaoke singing of the second (third) of the music X. The reference data, the reference data of the music X', and the reference data of the music X'are compared with each other, and the highest scoring value is output to the presentation unit 400.

[Presentation section]
The presentation unit 400 presents the determined scoring value. When the scoring value is determined for each predetermined performance section, the presenting unit 400 may present the scoring value for each predetermined performance section determined.

For example, the presentation unit 400 can display the score value and the total score for each performance section on the display screen of the display device 30 after the karaoke performance (karaoke singing) of the music X is completed (see FIG. 3). .. The total score may be, for example, the average value of the scoring values for each of the three performance sections. Alternatively, the presentation unit 400 may emit a score value via the speaker 20 after the karaoke performance (karaoke singing) of the music X is completed. Alternatively, when the dedicated application software is running on the mobile terminal owned by the user, the presentation unit 400 transmits the score value information to the mobile terminal, and the mobile terminal displays the same display as in FIG. It is also possible to do it.

== About the operation of the karaoke device 1 ==
Next, a specific example of the operation of the karaoke device 1 in the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing an operation example of the karaoke device 1.

The user makes a reservation for the music X via the remote control device 50 (music reservation. Step 10).

The music determination unit 100 determines whether or not there is a music with a different version in the music X (determines whether or not there is a music with a different version. Step 11).

When there is a music having a different version (Y in step 12), the music determination unit 100 outputs the determination result to the reference data acquisition unit 200.

The reference data acquisition unit 200 acquires reference data of songs of different versions from the storage unit 13 (acquisition of reference data. Step 13).

The scoring value determination unit 300 calculates the scoring value by comparing the singing voice data associated with the karaoke singing of the music X with the reference data of the music X and the reference data of the music of different versions acquired in step 13 ( The score value is calculated for each reference data. Step 14).

The scoring value determination unit 300 determines the highest scoring value from the plurality of scoring values calculated in step 14 as the scoring value of the karaoke song (determination of the scoring value. Step 15).

The presentation unit 400 presents the determined scoring value (presentation of the scoring value. Step 16).

As is clear from the above, the karaoke device 1 according to the present embodiment includes a music determination unit 100, a reference data acquisition unit 200, a scoring value determination unit 300, and a presentation unit 400. For example, when the music X is selected, the music determination unit 100 determines whether or not there is a music having a different version of the music X. When it is determined that there is a music having a different version, the reference data acquisition unit 200 acquires the reference data of the music having a different version. The scoring value determination unit 300 calculates the scoring value by comparing the singing voice data associated with the karaoke singing of the music X with the reference data of the music X and the reference data of the acquired songs of different versions, and the highest scoring value. Is determined as the scoring value of the karaoke song. The presentation unit 400 presents the determined scoring value.

In this way, when there are songs with different versions in the selected songs, a plurality of scoring values are calculated for one karaoke song by comparing the singing voice data with the reference data of all those songs. The Rukoto. Here, for example, even if the singing is performed by tune the songs of different versions according to the karaoke performance of a certain song selected, the scoring value determination unit 300 also calculates the scoring value based on the reference data of the songs of different versions. Therefore, it is possible to obtain an accurate score value for the actual karaoke singing. That is, according to the karaoke device 1 according to the present embodiment, when singing a karaoke song in which a song having a different version exists, the user accurately sings the song according to which version of the song. Can be graded.

Further, the scoring value determining unit 300 according to the present embodiment determines the scoring value for each predetermined performance section of a certain musical piece. Therefore, even when the singing style is changed for each predetermined performance section, an accurate score value can be obtained for each performance section. In addition, the presentation unit 400 according to the present embodiment presents a score value for each predetermined performance section determined. Therefore, the user can grasp the score value for each performance section.

Further, the music determination unit 100 according to the present embodiment searches for a music having the same music name as a certain music, and if there is a music having the same music name, the lyrics data of the searched music and the lyrics of the certain music. By comparing with the data, it is determined whether or not there is a music with a different version. In this way, by using the information (song name and lyrics data) common to a certain song and a song having a different version, it is possible to reliably determine the presence or absence of a song having a different version.

<Modification example 1>
The key and tempo of the song may differ between the selected song and the song with a different version. In this case, if the scoring value is calculated based on the reference data of each song, an accurate scoring value cannot be obtained.

Therefore, when the key of a certain music and the key of the music having a different version are different, the scoring value determining unit 300 may calculate the scoring value by matching the key of the music having a different version with the key of the music. Alternatively, when the tempo of a certain song and the tempo of a song having a different version are different from each other, the scoring value determining unit 300 may calculate the scoring value by matching the tempo of the song with a different version to the tempo of the song.

A known method can be used as a method of matching the key or tempo of a different version of a song to the key or tempo of a selected song. For example, the scoring value determination unit 300 compares the keys included in the reference data of the different versions of the music with the keys of the selected music, and if the keys have a difference d, the reference data of the different versions of the music. The score value is calculated after changing only the difference d so that the key included in is matched with the key of the selected song.
