Description

  The present invention relates to a high difficulty singing section notification karaoke system that uses a predetermined singing section as a display unit and displays a singing section having a high singing difficulty in an identifiable manner for a lyrics telop for each display unit according to the progress of karaoke performance. is there.

  In recent music, there is a singing section that is partially difficult to sing. For example, a section including a note with a temporary symbol, a section including a syncopation note, a section including an aftert note, a section including an unequal score note, and the like. Since these sections each require a characteristic way of singing, it becomes a highly difficult music for those who are unskilled in singing.

  By the way, a general karaoke performance device has a function of displaying a lyrics telop for each predetermined singing section as the karaoke performance progresses. Then, by confirming what kind of lyrics should be sung next by changing the color of the lyrics telop, the singing can be performed without making a mistake in the lyrics and singing timing. However, the lyrics telop does not represent the difficulty of singing, and there is a case where the singing section has to be sung before the singing section having a high singing difficulty is prepared.

  Conventionally, a technique for objectively determining a singing difficulty level has been disclosed (see Patent Document 1 and Patent Document 2). The technique described in Patent Document 1 refers to performance data, extracts singing technique symbols that exist between breathing marks, performs predetermined calculation processing, and calculates a singing level.

  The technique described in Patent Document 2 is a technique that automatically determines the difficulty level based on performance data, and accurately determines the skill of actual singing using the difficulty level. That is, the data of the guide melody track of performance data is taken in, the average value of the sound length of each note is obtained, and it is determined that the difficulty is higher as the sound length average value is smaller. Further, an average value of pitch differences between the notes before and after the guide melody is obtained, and it is determined that the difficulty level is higher as the pitch difference average value is larger. Further, a range that is the difference between the highest and lowest sounds in the singing melody is obtained, and it is determined that the difficulty is higher as the range is wider. Also, the appearance frequency of a specific pitch (for example, a rising pitch of 7 degrees or higher or a falling pitch of 6 degrees or higher) in the singing melody is calculated, and the higher the appearance frequency, the higher the difficulty level is determined. Then, the difficulty level is determined by these methods, and the score of the scoring result is weighted according to the difficulty level.

JP 2005-31132 A JP 2005-107333 A

  However, although the techniques described in Patent Document 1 and Patent Document 2 described above can objectively determine the difficulty level of singing based on performance data, singing is actually performed while singing. The degree of difficulty of singing cannot be notified to the person. Therefore, in the conventional technique, although the difficulty level of the singing is determined, this difficulty level cannot be used for singing assistance.

  Therefore, when a person who is unskilled in singing tries to sing a highly difficult song, the singing is promoted by notifying the highly difficult singing section in advance, so that he will be ready to become a highly difficult singing section. The development of a technology that can provide assistance is desired.

  The present invention has been proposed in view of the above-described circumstances, and extracts singing sections with high difficulty by referring to performance data, informs the singing sections with high difficulty only by displaying lyrics telop, and assists singing. It is an object to provide a high difficulty singing section notification karaoke system capable of performing the above.

The high difficulty singing section notification karaoke system of the present invention has the following features in order to achieve the above-described object. That is, the high difficulty singing section notification karaoke system of the present invention displays a predetermined singing section as a display unit, and displays a singing section having a high singing difficulty with respect to the lyrics telop for each display unit according to the progress of the karaoke performance. A system comprising a singing grading history storage means, a high difficulty singing section setting means, and a high difficulty display control means.

The singing scoring history storage means is a singing scoring value for each predetermined singing section scored using a singing scoring function, a user ID of the user, and the music for any music sung by an arbitrary user. Is a means for associating the song ID with the song singing history database. The high difficulty singing section setting means refers to the performance data corresponding to each display unit for an arbitrary piece of music, and sets the type of the high difficulty code for a display unit including a predetermined type of high difficulty singing code. This is a means for setting a high difficulty level type flag to be expressed and storing it as a high difficulty singing section database by music. The high difficulty level display control means refers to the high difficulty level singing section database by music, and when the high difficulty level flag is set in an arbitrary display unit, the high difficulty level type flag is set for the lyrics telop of the display unit. For the music linked to an arbitrary user stored in the singing grading history database with reference to the singing grading history database, the lyric telop of the display unit that is not identifiable is displayed. Singing section in which high difficulty level display is controlled only for display units corresponding to singing sections in which the score value by the user's singing is less than a predetermined reference value , and the scoring value by the user's singing is a predetermined reference value or more Is a means for controlling so as not to control the high difficulty display .

  In the high difficulty singing section notification karaoke system having such a configuration, the singing difficulty is determined for each display unit based on the singing code included in the performance data (MIDI (registered trademark) data), and the display unit becomes a high difficulty. Then, the display mode of the lyrics telop is changed to display the high difficulty type. Note that the display unit is a unit of lyrics telop displayed in one block on the display device when playing karaoke music, and a singing section is divided by a phrase having a good delimiter to be one display unit. .

  In this high difficulty singing section notification karaoke system, a predetermined high difficulty singing code is stored. The high difficulty singing code is, for example, a code representing a type such as a temporary symbol, a syncopation, an outcome, an unequal score. And the performance data is referred for every display unit about arbitrary music by the high difficulty song section setting means. Here, if a high difficulty singing code is included, a high difficulty type flag indicating the type of the high difficulty singing code is set for the display section, and the high difficulty singing section database is stored. Furthermore, the lyrics telop is displayed by the high difficulty level display control means in a display mode that can identify the high difficulty level for the display unit in which the high difficulty level flag is set. The display mode of the lyrics telop that can be identified as having a high degree of difficulty is, for example, a different color scheme, a different size, a different shape, and the like as compared with the default lyrics telop.

  In the high difficulty singing section notification karaoke system having such a configuration, it is determined whether or not to display the high difficulty according to the singing grading history for each user. That is, when an arbitrary user sings an arbitrary piece of music by the singing grading function, singing is performed. And by the singing history storage means, the singing scoring value for each predetermined singing section scored using the singing scoring function, the user ID of the user, and the music ID of the music are linked, and the singing scoring is performed. Store as history database. When an arbitrary user selects an arbitrary piece of music, the singing score history database is referred to, and the singing score value is compared with a predetermined reference value for the song of the piece of music by the user. Then, the lyrics telop is displayed so that the difficulty level can be identified only in the display unit corresponding to the singing section in which the scoring value by the user's singing is less than the predetermined reference value.

  The display device displays the lyrics telop for each display unit according to the progress of the karaoke performance. In the display section corresponding to the high difficulty singing section, the high difficulty type flag is used so that the singing difficulty is high. The lyrics telop is displayed at a normal display timing on the karaoke performance terminal in a display mode with a high degree of difficulty corresponding to.

  In the high difficulty singing section notification karaoke system of the present invention, in the display section corresponding to the high difficulty singing section, the lyrics telop is displayed in a high difficulty display mode corresponding to the high difficulty type so that it can be identified that the difficulty is high in advance. Is done. Therefore, it is possible to urge the attitude toward a highly difficult singing section, and even an unskilled person can assist so that the singing ability corresponding to his / her skill can be exhibited. In other words, it is possible to read a high difficulty singing code from the score and recognize the high difficulty singing section, but on the karaoke display screen where the lyrics telop must be displayed, the score is displayed simultaneously with the lyrics telop. Is virtually impossible. In this regard, in the high difficulty singing section notification karaoke system of the present invention, the high difficulty singing section can be easily recognized only by displaying the lyrics telop without displaying the score on the display screen.

  In addition, according to the singing grading history for each user, when the lyrics telop is displayed in a display mode with a high degree of difficulty corresponding to the singing ability of the user, the difficulty level corresponds to the skill of the user. Since it is judged, it can assist so that the singing power corresponding to one's skill can be demonstrated still more reliably.

Hereinafter, an embodiment of a high difficulty singing section notification karaoke system of the present invention will be described with reference to the drawings.
