BACKGROUND OF THE INVENTION
The present invention relates to a karaoke performance method and system for synchronizing and displaying lyrics subtitles together with karaoke accompaniment music, and more particularly to a performance control technique for karaoke performance of polyphonic choral tunes and choral tunes.
[0002]
[Prior art]
Karaoke songs include choral songs and chorus songs that include parts that are not the same in a plurality of voice parts, or that include parts that are not the same in utterance timing even with the same lyrics. Many duets are also choral songs. Many of the duets that belong to so-called pop songs have two voices, but the composition of the song is monophonic, so the lyrics subtitles corresponding to the two voices are displayed on the screen at the same time, and one singing part Is displayed, the lyrics subtitles for the singer in charge of the part are displayed in different colors (Japanese Patent Laid-Open No. 9-212177) .
[0003]
Even for group music with a larger number of voice parts, the singer usually sings one voice part corresponding to the main melody, and the lyrics subtitles are also displayed in different colors for the voice part. Yes. The other voice part outputs sound only for the accompaniment sound. In a karaoke apparatus equipped with a harmony function for outputting the main melody chords with the voice of the singer, if the other voice part is harmony, the other voice part is created in a pseudo manner from the singing voice of the singer (Japanese Patent Application Laid-Open No. 2000-2000) -315100 publication) . Of course, it is also conceivable to record other voice parts as chorus sounds in a predetermined format such as ADPCM and reproduce and output chorus sounds of other voice parts during performance (Japanese Patent Laid-Open No. 2000-231390) .
[0004]
[Problems to be solved by the invention]
Recently, gospel-style polyphonic choral songs and choral songs have become popular, and many songs have been created and introduced into karaoke. When singing polyphonic group music between friends, if each person sings the voice of one of the members of the group, they can become a group and enjoy karaoke. However, if the lyrics are different for each voice part, or if the utterance timing is different for the same lyrics, multiple users will sing individual voice parts, and each user will be responsible for their voice part. It is difficult to grasp the lyrics subtitles and the timing of their utterance. Therefore, there is a possibility of singing other voice parts or failing to sing one's own voice part. Therefore, unless each user understands his / her voice accurately, it is very difficult to sing well by unifying and coordinating all voices.

Is stored with karaoke data including accompaniment music data mainly composed of MIDI data and lyric rendering data that is the origin of the generation of lyric images. In the accompaniment music data, each of a large number of sound sources built in the synthesizer 8 is used as one musical instrument, and the sound generation / mute timing, pitch, volume, etc. are specified for the performance sound to be generated by each musical instrument. Also, information (chorus data file name, etc.) for specifying ADPCM format voice data (chorus data) obtained by sampling the vocal part of each member's vocal parts in the back chorus and group music, and its pronunciation timing are also MIDI. It is described in accompaniment music data as control data in the data. Therefore, the chorus data file is also stored in the hard disk device 3.
[0011]
The lyric rendering data includes lyric characters, lyrics character string display / erase timing, instruction information for changing the color of characters at the singing timing in the displayed character string, and the like. Further, the hard disk device 3 has a predetermined format of moving image data for a long time, script data defining a processing sequence of moving image data (storage location and processing order of moving image data to be processed, etc.), and playable karaoke music Table of contents information such as song name, artist name, year of publication, and singing part of lyrics is also stored. And the central control part 11 identifies the karaoke data, script data, and table of contents information of each music by a music number, and manages this as a karaoke database. The central control unit 2 communicates with a host device connected to a predetermined information communication network via the communication control unit 16 in a timely manner, obtains karaoke data, script data, table of contents information, etc. about the new musical piece, The database contents are updated from time to time.
[0012]
FIGS. 2A and 2B are an external view and a functional block diagram of the karaoke music selection apparatus 20. The karaoke music selection device 20 includes a user interface mainly composed of a touch panel 22 in which a liquid crystal display (LCD) 22a and a touch sensor 22b are stacked, and the built-in flash memory 24 is the same as that stored in the karaoke device 1. The table of contents information and various image information displayed on the touch panel 22 are stored. The device control unit 21 that controls the karaoke music selection device 20 includes a CPU, a RAM, a ROM, a video RAM, and the like, and includes information input to the touch panel 22 and information obtained through wireless communication with the karaoke device 1 via the communication interface 27. Based on this, various image information and character information are bitmap-developed in the video RAM, and the LCD driver 25 is driven based on the bitmap data to display appropriate information on the touch panel 22. The table of contents information stored in the flash memory 24 is managed as a music index database, and the music index database is updated by communicating with the karaoke apparatus 1 in a timely manner.
[0013]
The device control unit 21 accepts a piece of table of contents information as a query through dialogue with the user via the touch panel 22 and extracts the table of contents information of the corresponding karaoke piece from the song index database and presents it. When a specific music is finally designated by the user, a performance reservation command including the music identifier (music number) is transmitted to the karaoke apparatus 1 by radio signal via the communication interface 27. 3A to 3E show screen transitions in the karaoke music selection apparatus until the performance reservation command is transmitted. In this example, the table of contents information is searched based on a part of the music title, and one finally narrowed down music is designated.
[0014]
When the central control unit 2 receives a performance reservation command including a music number from the operation panel 6 provided in the karaoke apparatus 1 or the attached remote control transmitter 5 via the operation control unit 7, or the karaoke music selection When a performance reservation command from the apparatus 20 is received via the wireless communication interface 15, the number is stored in an internal RAM and managed in a performance processing queue. Then, the music numbers are sequentially extracted from the queue, the corresponding karaoke data is read from the hard disk device 3, and the accompaniment music data in the karaoke data is transferred to the synthesizer 8 to generate accompaniment music. As for the chorus sound, a designated chorus data file is transferred to the synthesizer 8 at a designated timing. The synthesizer 8 has a built-in D / A converter for decoding ADPCM data into an analog audio signal. The audio signal obtained by decoding the transferred chorus data file is the sound of accompaniment music originating from MIDI data. Output with signal.
[0015]
On the other hand, for the lyric rendering data, the lyric image in which the portion to be sung is changed in color in synchronism with the accompaniment music is sequentially developed in the video RAM 12 as a bitmap. Also, predetermined moving image data is sequentially transferred to the video control unit 13 in a predetermined order based on the script data, and the background moving image of the lyrics image is decoded.
[0016]
The mixing amplifier 9 mixes and amplifies the accompaniment music and the accompanying back chorus and the singing voice input to the microphone 11 and outputs the sound from the speaker 10. The video control unit 13 superimposes the lyrics image on the decoded moving image and displays and outputs it on the display 14.
[0017]
=== Performance control ===
According to the performance method of the present embodiment, when playing a song having a plurality of voice parts such as choral music and multiple chords, the user responsible for singing each voice confirms the lyrics of the voice of the user and the sounding timing thereof. can do. For example, a group song having five voices is sung by five users. Each of the five users has the karaoke music selection device 20 individually, and designates the same group music in each music selection device 20 and also specifies the voice part that he / she is responsible for. 4A to 4C show an outline of the user interface environment when the group music and the voice part are designated.
[0018]
In the music index database of the karaoke music selection apparatus 20, for group music having a plurality of voice parts, each voice part is identified by a voice ID, and the name of the member of the original song group is associated with each voice ID. . Then, the karaoke music selection device 20 is a “member designation” button for guiding to a screen for designating a voice part when a user finally specifies and the music is a group music in the same manner as general karaoke music. When this button 30 is instructed, the karaoke music selection apparatus displaying 30 displays a list of member names 31 of the original song group (B). Each user selects a different member from the list displayed on the karaoke music selection apparatus 20 operated by each user, and instructs the “decide” button 32 to perform an operation for reserving the performance of the group music. In response to this operation, the karaoke music selection device 20 displays a confirmation screen (C) and reserves a performance reservation including its own identification information (device ID), the song number of the group song, and the voice ID corresponding to the member. The command is transmitted to the karaoke apparatus 1.
[0019]
In the karaoke database of the karaoke apparatus 1, a plurality of voice IDs are associated with a music number for group songs that are sung at different utterance timings even if the voices have different lyrics or the same lyrics. Individual lyric rendering data (voice part-specific lyric data) are managed in association with each other. When the central control unit 2 receives a performance reservation command including the song number, voice ID, and device ID of the group song from each karaoke song selection device 20 via the wireless communication interface 15, the voice ID of this song is determined. Waiting for all of them to be registered, the music numbers of this group music are registered in the queue, and the voice ID and the device ID are stored in association with each other.
[0020]
When the correspondence between the voice ID and the device ID is stored in relation to the music number extracted from the queue, the central control unit 2 is synchronized with processing the corresponding karaoke data and playing the accompaniment music. Then, based on each voice part ID and the apparatus ID, the corresponding lyric data for each voice part is sent to the corresponding karaoke music selection apparatus 20. Each karaoke music selection device 20 performs display / erasure of the lyric character string and color change display based on the lyric data for each voice part sent from the karaoke device 1. FIG. 5 shows the display state of lyrics in each karaoke music selection apparatus 20. In this embodiment, the voice-specific lyrics data includes a lyrics character string for all voice parts not including the color change instruction information, and a lyrics character string assigned to the corresponding voice part including the color change instruction information, Each karaoke music selection device 20 displays the lyric characters 33 for all voice parts, and the lyric characters 34 of its own voice part are bolded and displayed separately from the lyrics of other voice parts 35. Based on the color change instruction information, the bold character 34 is displayed in a color-changed manner in synchronization with the voice timing of the voice part.
[0021]
=== About duplication and lack of voice ===
In the said Example, the number of voice parts and the singer of a group music are the same number, and each singer shared the voice part. However, when a plurality of users arbitrarily specify the group music and the voice part, the same voice part may overlap for the same group music. Corresponding to such a case, for example, if a certain voice part is designated for a certain group song, the karaoke apparatus will receive a performance command designating the group musical piece and the voice part thereafter, What is necessary is just not to accept the performance reservation. Then, this is notified to the karaoke music selection apparatus that has sent this command, and the karaoke music selection apparatus may display the notification appropriately.
[0022]
On the other hand, a case where the number of users is smaller than the voice part of the group musical piece or a case where a user who is in charge of a specific voice part does not appear is assumed. In such a case, chorus data for all voices of the group music is prepared in the karaoke apparatus, and when the group music is played, the chorus of the insufficient voice may be reproduced and output.
[0023]
=== Regarding the display control of lyrics subtitles ===
There may be a companion other than the person who sings the group music. For this companion, watching the lyrics subtitles for all voices rather than the lyrics subtitles for each voice makes it easier to grasp the progress of the music and enjoys karaoke performance. Therefore, the lyrics subtitles for all voices may be displayed on a display different from the karaoke music selection device, and the lyrics subtitles may be displayed in different colors in synchronization with the performance.
[0024]
【The invention's effect】
According to the karaoke performance method of the present invention, a plurality of voices are played by a plurality of users on a chorus or a chorus that includes parts that are not the same in a plurality of voice parts, or that include parts in which the utterance timing is not the same even with the same lyrics. When singing by sharing each part, the user in charge can surely grasp the lyrics and utterance timing of each voice part, and can sing well by unifying and coordinating all voice parts.
