Description

  The present invention relates to a system for automatically setting performance keys that allow a karaoke user to sing the music most suitably when singing the desired music.

  Conventionally, when a karaoke user makes a performance reservation for a desired music piece, the user uses a remote control device attached to the karaoke performance device. Specifically, using a GUI (Graphical User Interface) of the remote control device, a search keyword input by the user is referred to a database built in as a query related to attribute information, and attribute information and music ID for the corresponding music are presented. Output. When the music is finally designated, the performance reservation code including the music ID is transferred as a remote control signal to the nearest karaoke performance apparatus. The karaoke performance device stores and manages karaoke data, which is the origin of generation of accompaniment music and lyric images, in association with a song ID for a large number of karaoke songs, and is included in the signal when a remote control signal is received. The music reservation ID is managed as a performance reservation queue to complete the performance reservation.

  Furthermore, in a recent karaoke system, if a predetermined procedure is followed at the time of performance reservation, the user ID and the performance reservation code are remote-controlled to the user whose login has been confirmed by the user ID acquisition means. Performance reservations can be made by multiplexing the signals. That is, at present, a mechanism has been established so that who knows which music piece has been reserved for performance. For example, using such a mechanism, when a performance reservation queue is disclosed on a predetermined display, there is a service that displays a face photograph or name associated with a user ID for each performance reservation item.

  By the way, a general karaoke performance device includes a performance key controller. Normally, by operating the operation panel of the remote controller or the karaoke performance apparatus main body, the actual performance setting key can be raised or lowered in semitone units with respect to the default key. For example, “+1” is displayed when a semitone is raised, and “+2” is displayed when a semitone is raised further. Similarly, “−1” is displayed when a half tone is lowered. Using this, the user can set the performance key by sliding the range of the accompaniment music according to his / her preference.

  On the other hand, most karaoke songs are designed to be played with a default key different from the performance key of the original song so as to match the vocal range of a person with average singing ability. This is because the vocal range is different between a professional singer with excellent singing ability and an amateur. The music table of contents information includes an item “original music key setting” indicating a difference between the default key and the original music key of each music. In this item column, “+3” “+2” “+1” “0” “ A numerical value such as “−1” is described. This numerical value is a semitone numerical value, and represents how the performance key control mechanism should be set in order to sing the music in the same range as the original music. For example, a song with the original song key “0” is played in the same range as the original song with the default setting, and “+1” indicates that the original song key is half a tone higher than the set key. That is, when playing this song, if the setting key is set to “+1” using the performance key control function of the karaoke performance device, the same range as that of the original song is obtained. Similarly, a song whose original song key is “−1” Lowering the key setting by a semitone results in the same range as the original song.

  Many karaoke users tend to search for the song they want to sing and transfer the song ID to the karaoke performance device at the time of making a performance reservation for the song, and how to set the performance key during performance I don't have that in mind. Normally, while listening to other people's singing until their singing order arrives, they gradually regain their coolness from the busy schedule at the time of performance reservation and try to set the performance key when they sing. Therefore, if you are familiar with your own singing range or remember each setting key for each song, you can set the key immediately. There are inconveniences such as changing or not being able to set keys.

  In order to eliminate such inconvenience, various techniques have been conceived in the past. For example, in Patent Document 1, information indicating the voice band necessary for singing is stored in each musical piece, and the highest range value and the lowest range value are input from a microphone and recorded as range information that can be uttered by the user. Then, the voice band information of the music and the user's band information are compared to detect the band difference between them, and the performance key is automatically set by the performance key controller according to the detection result, or the voice band information and A technique for displaying user range information is disclosed. Also, in Patent Document 2, the selected music ID and the setting key for the previous performance are stored in a predetermined recording medium (IC card or the like), the recording medium is inserted into a karaoke performance device, and a desired music is called. Thus, a technique for automatically changing a performance key is disclosed.

Japanese Patent Application Laid-Open No. 06-051790 JP 08-146978 A

  However, even if the user's range information is recorded, a complicated mechanism and high cost are required from voice input to range analysis, or even if voice band information or user range information is displayed, Does not know how to set the performance key. Even if the performance key at the time of the previous performance is recorded for each song on a predetermined recording medium, and the key is automatically set at the time of singing this time, the user's range may change according to the tone of the vocal cord. In particular, when the quality of the performance at the time of the previous performance is prominent, it does not necessarily apply to the current singing, and the setting keys recorded on the recording medium are not necessarily suitable. Alternatively, although not disclosed in the above patent document, the user himself / herself manually registers a setting key for each piece of music in a predetermined recording medium, and then automatically changes the performance key. Considering the time when registering the setting key for each song and the long-term usage, considering the time required for changing the setting key for each song in accordance with the change in the sound range caused by the user's aging, chronic illness, etc. It is not preferable.

  Therefore, the present invention objectively extracts a suitable key without adopting a complicated mechanism such as sound range analysis, and without being influenced by the tone of the temporary vocal cords, and further reduces the time and effort of the user. An object of the present invention is to provide a system that can efficiently and automatically set a performance key that is most suitable for the user when playing the music, corresponding to the music that the user has reserved for performance.

  In view of the above problems, each time an arbitrary user whose user ID is specified sings a piece of music that is associated with the user ID and reserved for performance, the user ID and the music ID and the user ID are recorded. The scoring results are linked, the setting key information set at the time of singing is managed, and when an arbitrary user makes a performance reservation for a desired piece of music, based on the user ID, If the setting key information set is managed, the setting key having the highest average value of the scoring results (weighted average of the scoring values) is extracted as a suitable key in the setting key information, and when the music is played The inventors have found that the above-mentioned problems can be solved by a system that automatically sets the preferred key as a performance key of the music, and have come up with the preferred key setting system for each music according to the present invention.

That is, the user-specific music-specific key setting system according to the present invention includes a karaoke performance device having a performance key control function, and includes a user ID acquisition means, a singing ability scoring means, and a user-specific music-specific setting key management.

(A) The user ID acquisition means specifies a user ID logged into the system,
(A) When the user sings a predetermined song, the singing ability scoring means calculates a scoring result for the singing voice,
(C) The user-specific song-specific setting key management means displays the user ID, the song ID, and the scoring result each time an arbitrary user sings a song that is associated with the user ID and reserved for performance. Linking and managing the setting key information set at the time of singing in the setting key history management unit,
(D) The user-specific song-specific key extraction means is a setting key set for the user's song based on the user ID when an arbitrary user reserves a performance of the desired song. When the information is managed by the setting key history management unit, based on the scoring result for each setting key, the setting key having the highest average value is extracted as a suitable key,
(E) The user-specific music-specific suitable key setting means automatically sets the extracted suitable key as a performance key of the music when the music is played.
It is characterized by that.

  According to the preferred key setting system for each user's music according to the present invention, the setting key information set for the song sung for each user is managed, and the average value of the highest scoring results is set in the setting key information. In order to extract the setting key having as a suitable key and set this suitable key as the performance key of the music when the music is played, the user does not need any trouble, and for the music reserved for the performance, The most suitable performance key determined objectively can be automatically and efficiently set when the music is played, and the user can be guided to singing in a suitable range.

  A preferred key setting system for each user-specific music according to the present invention will be described below with reference to a preferred embodiment. First, a block diagram of a karaoke performance apparatus according to the present invention shown in FIG. 1 and FIG.

This history management table (T1) is managed by the user-specific song-specific setting key management means, and mainly includes a “user ID field” (f1) for identifying the user and the user singing. A “song ID” field (f2) for specifying a song that has been played, a “setting key” field (f3) indicating a performance key set at the time of singing, and the number of singing times or singing frequency (for example, “Singing Count” field (f4) indicating the number of singing in the past year), “Scoring Total” field (f5) indicating the total of scoring results by singing with the setting key, and “Scoring Total” The “average scoring value” field (f6) indicating the average value of the scoring results calculated by dividing by “the number of times of singing” is included.

  Specifically, in the figure, “User A” sings seven songs “Music A” to “Music G” during a predetermined period, and calculates the average value of the scoring results for each set key in each song. Has been. Then, when the user makes a reservation for playing a desired song, the user-specific song-specific suitable key extraction means is the most preferable setting key information set for the user's song based on the user ID. A setting key having a high average value of scoring results is extracted as a suitable key. For example, when “User A” makes a reservation for performance of “Song A” in the figure, “+1”, which has the highest “average scoring value” (95.326 points), is extracted as a suitable key. (In addition, in the figure, bold letters indicate the preferred key and its highest average score)

  The user-specific music-specific suitable key setting means automatically sets the extracted suitable key as the performance key of the music when the music is played. Specifically, in this embodiment, regarding the symbol notation of the “setting key”, the numerical value is shown in semitone units, and “+” and “−” indicate the vertical relationship of the pitch. The music-specific suitable key setting means controls the performance key controller.

  In this embodiment, the setting key history management unit is provided in each karaoke performance device so that only each karaoke performance device manages setting key information in which scoring results are associated with each user-specific song. Although the system is configured, in the present invention, the karaoke host device centrally manages the setting key information for each song by user and collects the setting key information from any karaoke performance device connected to this karaoke host device. At the same time, based on this setting key information, the following configuration may be adopted so that the user can receive the same service in any connected karaoke performance device.

  Here, based on the conceptual block diagram of the communication karaoke system concerning another Example shown in FIG. 6, and the block block diagram of the karaoke host apparatus concerning another Example shown in FIG. 7, this invention is demonstrated further in detail. Describe.
