=== Singing scoring function ===
The karaoke apparatus 10 according to the present embodiment has a singing scoring function and performs a well-known karaoke competition. When the performance of the karaoke competition participating song is started, the singing scoring unit 19 samples the singing voice signal collected from the microphone and converts it into digital singing voice data under the control of the central control unit 11, and extracts the singing voice pitch. Compared with the pitch reference value based on the main melody of karaoke data, the section score with a maximum score of 100 is sequentially output for each appropriately divided phrase. The central control unit 11 aggregates the section scores that are sequentially output, and calculates and outputs an average value of the section scores from the start of performance as the progress score. After the performance is completed, the central control unit 11 sums up the section scores output so far and displays the average score on the display 18 as the final score.

  In addition, the central control unit 11 obtains a ranking table for the music from the karaoke server 70 as a scoring information server. For example, the top 10 scoring ranks are displayed on the display 18 based on the ranking table in which the scores are tabulated in descending order by the server 70. Of course, it may be displayed to the lowest level by scrolling. Then, the progress score to be sequentially output is compared with each score in the ranking table, and the current ranking of the progress score is sequentially monitored.

  When the performance of the karaoke competition participating music is finished, the central control unit 11 reflects the final score in the ranking table, and transmits the score, the music number, and the member ID of the singer to the karaoke server 70. Based on this, the server 70 updates the ranking table and updates the member singing history information.

  In addition, the karaoke data of a present Example is divided | segmented for every phrase with the appropriate delimiter code, and each phrase is comprised so that identification by phrase division ID is possible. The section scores (score-specific score data) that are sequentially output are recorded in association with the phrase category IDs.

=== Scoring information database ===
A feature of the present invention is that a karaoke server 70 as a scoring information server constructs a scoring information database, and creates and manages a high difficulty phrase table based on the database.
The scoring information database stores a large number of records in which phrase IDs and section scores are associated with music IDs. The karaoke apparatus 10 is a karaoke server serving as a scoring information server, in addition to the above-described processing for transmitting the final score when the performance of the karaoke contest participation song is completed, and a record in which the section score and the phrase category ID are sequentially output. 70. The karaoke server 70 manages a large number of records collected from karaoke apparatuses 10 in various places as a scoring information database.

The karaoke server 70 as a scoring information server creates and manages a high difficulty phrase table based on the records of the scoring information database. This table associates phrase category IDs of phrases having a high degree of difficulty for each music piece with the music piece ID as key information.
The karaoke server 70 calculates the average score for each phrase by counting the segment scores for each phrase category ID for each music ID for a large number of records collected in an appropriate period in the scoring information database. And a phrase with a relatively low average score is specified as a high difficulty phrase based on the transition of the average score for each phrase in the song with the song ID.

  Various methods can be applied to the method for specifying the high difficulty phrase, and the phrase is not particularly limited in the present invention. For example, the standard deviation of the average score for each phrase in one piece of music is calculated, and a phrase having a predetermined deviation value or less is specified as a high difficulty phrase. A phrase in which the difference between the previous and subsequent phrases and the average score or deviation value greatly decreases by a predetermined width or more may be specified as the high difficulty phrase.

  Of course, the phrase may be specified as a high difficulty phrase when the average score in one music is equal to or less than a predetermined score, that is, when the average score is absolutely low. In that case, the absolute number of high difficulty phrases increases in the music with high difficulty through the music.

  Alternatively, for each record, a low score phrase (or a low deviation value phrase less than a predetermined deviation value) that is less than or equal to a predetermined score is specified based on the transition of the segment score for each phrase category ID, and the number of records for the same music ID is low. A method may be used in which score phrases (low deviation value phrases) are aggregated to identify high difficulty phrases. For example, each low scoring phrase (low deviation value phrase) whose average score is a predetermined score or less may be specified as a high difficulty phrase, or many records are specified as a low scoring phrase (low deviation value phrase). Phrases with a large number of times may be specified as high difficulty phrases.

The karaoke server 70 stores the average score data and phrase category ID of the specified high difficulty phrase in association with the music ID, and manages this as a high difficulty phrase table. FIG. 3 illustrates a logical data configuration of the high difficulty phrase table. Moreover, if the high difficulty phrase is re-identified by adding up the section scores as appropriate, the high difficulty phrase table is updated and managed so as to be in the latest state.
The karaoke apparatus 10 can communicate with the karaoke server 70 via the LAN 110 to refer to the high difficulty phrase table.

  Note that the high difficulty phrase table may be stored in the karaoke apparatus 10 for use. The karaoke apparatus 10 may communicate with the karaoke server 70 as appropriate to update and manage the table.

=== High difficulty phrase display ===
The central control unit 11 of the karaoke apparatus 10 accesses the karaoke server 70 based on the music ID when preparing to play the karaoke contest participation music, and the high difficulty phrase category ID corresponding to the music ID and the average score data thereof. Are obtained from the high difficulty phrase table and temporarily stored in an appropriate storage unit.

  During the performance of the music, the high difficulty phrase is indicated in synchronization with the performance of the high difficulty phrase category ID. For example, as shown in the example screen in FIG. 4, the message “This is a difficult point” is displayed in a conspicuous manner, such as blinking prominently, along with the lyrics subtitles synchronized with the performance. Further, the average score of the phrase is displayed on the display 18. Furthermore, immediately after the phrase singing, the score of the section of the scored phrase may be displayed.

  Prior to the performance of the high-difficulty phrase, for example, a notice may be displayed so that the high-difficulty phrase is played several phrases later (or after a predetermined time). It makes it easier for singers to prepare their hearts.

  After the performance of the music, the average score of the high difficulty phrase and the section score of the scored phrase are compared and displayed. For example, as illustrated in FIG. 5, for each high difficulty phrase, an average score and a section score are displayed together with lyrics subtitles. The high difficulty phrase and its lyrics subtitles, the average score, and the segment score are displayed one after another by the user's operation of turning the page. Since the user can see at a glance how many points he / she has scored for the difficult points that are the points for singing, the practice can be more effective.

  The display for displaying the high difficulty level phrase may be another dedicated display connected to the karaoke device 10 or a display of another device such as a touch panel of the user terminal 20 or a browser terminal connected to the LAN 110. High difficulty phrase display is possible without interfering with background images during karaoke performance.

It is a network block diagram of the communication karaoke system in the Example of this invention. It is a block block diagram of the karaoke apparatus of a present Example. The data logic structure of the high difficulty phrase table of a present Example is illustrated. It is the figure which illustrated the alerting | reporting screen of the high difficulty phrase in the karaoke apparatus of a present Example.
