Description

  The present invention relates to a system for automatically setting performance keys that allow a karaoke user to sing the music most preferably 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 music, if the setting key is set to “+1” using the performance key control function of the karaoke performance device, the same musical range as the original music is obtained. Lowering the key setting by a semitone results in the same range as the original song.

  Many karaoke users tend to search for a 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, etc. That is not 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. However, if you are familiar with your own singing range or remember each setting key for each song, you can set the key immediately, but it usually takes time to set the key until it fits repeatedly or repeatedly. 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, the present inventor specifies a user ID logged in to the system, and whenever an arbitrary user sings a piece of music that is associated with the user ID and reserved for performance, the user ID and The music ID is linked, the performance key history information set at the time of singing is managed, and when an arbitrary user reserves a performance for a desired music, the user's music is based on the user ID. If the history information of the performance key set for the music is managed, the setting key having the highest frequency in the history information is extracted as a suitable key, and when the music is played, the suitable key is used as the performance key of the music. As a result, the present inventors have found that the above-mentioned problems can be solved by a system that automatically sets the above, and have come up with a suitable key setting system for each user according to the present invention.

That is, the preferred key setting system for each user's music according to the present invention includes a karaoke performance device having a performance key control function, and includes a user ID acquisition means, a user-specific music-specific setting key management means, and a user's It is a system comprising suitable key extraction means by music and suitable key setting means by music by user,

  Hereinafter, an external perspective view of the remote control device attached to the karaoke performance device shown in FIG. 4, an interface display screen for user login / logout instructions shown in FIG. 5, and a setting key history management table shown in FIG. The present invention will be further described in detail based on the conceptual configuration diagram.

  First, as shown in FIG. 4, an interface of user ID acquisition means (9) constituted by an ID card reading / writing device is provided on the front surface of the remote control device of this embodiment, and a touch sensor is provided. A GUI (Graphical User Interface) environment mainly composed of stacked liquid crystal displays is provided, which forms a user interface (Rd). That is, the search function is realized by searching the music index database through the GUI dialogue and displaying the result. FIG. 5 shows the user-specific login / logout instruction interface display screen. On this display screen, a button row (30) with a face photo for each user, a “login” button (31) for logging in to the karaoke system, or a “logout” button (32) for logging out. Etc. are provided. According to the operation method, first, after the user selects the “login” button (32), the user ID associated therewith is loaded by loading his / her ID card in the user ID acquisition means. As soon as it is acquired, the login to the system is specified.

  Once the login is specified, the user's face photo registered in advance in the karaoke host device or, if not registered in advance, the user's face photo taken using the digital camera function attached to the remote control device is newly registered. Then, a user identification interface is created in which a predetermined button (30a) with a face photo for each user is posted for each user. Therefore, if a user reserves and registers a song immediately before or after selecting this button with a user-specific face photo, the user ID is given and a performance reservation is made. Then, performance key history information set at the time of singing the reserved music is managed by a predetermined setting key history management unit. In this embodiment, the “performance key set at the time of singing” adopts the last performance key when the key is changed many times during the singing. However, the present invention is not limited to this, and when the key is changed a plurality of times during performance, for example, the performance key setting time may be managed and the performance key set with the most time may be adopted. Absent.

  FIG. 6 is a conceptual configuration diagram of a setting key history management table mainly composed of the setting key history management unit. This history management table is managed by the user-specific music-specific setting key management means. Mainly, the “user ID field” (f1) for specifying the user and the music sung by the user are recorded. “Song ID” field (f2) for specifying, “Setting key” field (f3) indicating a performance key set at the time of singing, and setting frequency of the setting key (for example, songs sung in the past year) It is composed of a “setting frequency” field (f4) indicating the number of times of setting). Specifically, “user A” sings seven songs “music A” to “music G” during a predetermined period, and the setting frequency of the setting key in each music is counted. And when the user makes a reservation for playing a desired piece of music, the user-specific piece-by-speech suitable key extracting means uses the performance key history information set for the user's piece of music based on the user ID. The setting key with the highest frequency is extracted as a suitable key. For example, in the figure, when “User A” makes a performance reservation for “Song A”, “+1” having the highest setting frequency is extracted as a suitable key.

  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 the following, the overall operation flow when this system is used will be described in detail based on the flow conceptual diagram up to the preferred key automatic setting shown in FIG.

  First, when an arbitrary user logs in to the karaoke system from an arbitrary karaoke performance device using the user ID acquisition means (step: S1), data including the user ID is uploaded to the karaoke host device, and the user It is determined whether or not the performance key history information set corresponding to the ID is managed by the setting key history management unit in the host device (S2). If there is history information of the user, the setting key history management unit transfers the user history management table data to the karaoke performance device (S3). When the user makes a performance reservation for the desired music (S4), the history information of the performance key set for the user's music is managed by the transferred setting key history management unit of the user. (S5) If there is history information, the user-specific music-specific suitable key extracting means extracts the setting key having the highest frequency in the history information as the suitable key (S6).

  The extracted preferred key is temporarily stored in the hard disk or RAM of the karaoke performance device, and the preferred key setting unit for each user-specific song is used as the performance key of the song when the song is played. Automatic setting is performed (S7). When the music performance ends (S8), the user ID and the music ID are linked at a predetermined timing regardless of whether or not the preferred key is changed, and the history information of the set performance key is stored. The included song data is uploaded to the karaoke host device, and based on this, data is added to or updated in the history management table provided in the setting key history management unit of the host device (S9).

  In this embodiment, a series of operations from the user logging in to the system until the related data is added to or updated in the history management table of the karaoke host device is repeated until the user logs out. However, the present invention is not limited to this, for example, once the performance key history information set at the time of singing is managed by the setting key history management unit of the karaoke performance device, and after the user has logged out, it is collected for each user. The related data may be added to or updated in the history management table provided in the setting key history management unit of the karaoke host device.
