JP 2012-73310 A

  By the way, in recent years, a service that allows an original song for singing created by a user (contributing user) to be posted on a server and that allows other users (singing users) to sing the original song is being considered. . Since the music posted in this way is the original work of the posting user, even if the singing user tries to sing along with the playback of the posted music, the melody line is not understood as it is, and it may be difficult to sing. There was sex.

  An object of the present invention is to provide a posted music performance system and a posted music performance method in which a singing user can easily and smoothly sing the music even when the singing user does not know the melody line of the posted music of the posting user. There is to do.

  In order to achieve the above object, a posted music performance system according to a first aspect of the present invention is a posted transmission means for transmitting posted music data, musical score information of singing melody, and lyrics data relating to a music created by a posting user. In response to transmission from the posting transmission means, at least the posted music data, the score information, and the lyrics data are stored as posting data, and singing history information of each of a plurality of singing users is stored. Singing history storage means for performing, and based on an instruction from a specific singing user, posted music piece acquisition means for acquiring the posted music data and the lyrics data included in the posting data stored in the posting storage means from the posting storage means And the posted music data acquired by the posted music acquisition means based on the instruction of the specific singing user The singing history information of the corresponding specific singing user is based on the singing voice determining means for determining whether or not the corresponding singing voice data is included in the post data and the instruction of the specific singing user. Based on the singing history acquisition means acquired from the history storage means, and the singing history information acquired by the singing history acquisition means, the specific music for the singing melody of the posted music data acquired by the posted music acquisition means The melody knowledge determination means for determining the presence or absence of the knowledge of the singing user and the singing voice determination means determine that the singing voice data is not included in the posted data, and the melody knowledge determination means determines the posted music data. When it is determined that there is no knowledge of the specific singing user with respect to the singing melody, Based on the musical score information and the lyric data included in the stored post data, guide vocal generation means for generating a corresponding guide vocal voice by artificial voice, and the guide vocal voice generated by the guide vocal generation means And audio / music reproducing means for reproducing together with the posted music data acquired by the posted music acquiring means.

And according to the instruction | indication from the said specific song user, the song history acquisition means acquires the song history information of the specific song user from the song history storage means. Thereafter, based on the acquired singing history information, the melody knowledge determination means determines whether or not the specific singing user has knowledge of the singing melody of the posted music data (for example, whether there is a specific singing user's own singing history, Whether there is a singing history of another user simultaneously used with the specific singing user, etc.).

  In the determination of the singing voice determination means and the melody knowledge determination means, when it is determined that the singing voice data is not included in the posted data and there is no specific singing user knowledge regarding the posted music data, Difficult to sing due to unknown melody line. Therefore, in this case, guide vocal sound is generated by the guide vocal generating means using artificial speech based on the score information and the lyrics data in the post data. The generated guide vocal voice is reproduced together with the posted music data by the voice / music reproducing means.

  As a result, in the present invention, even if the singing user does not know the melody line of the posted song data of the posting user, the song can be sung easily and smoothly. Therefore, convenience can be improved.

  2nd invention has the singing genre determination means which determines the singing genre of the said specific singing user based on the said singing history information acquired by the said singing history acquisition means in the said 1st invention, The said guide vocal production | generation The means is characterized in that the guide vocal sound is generated using a parameter corresponding to the singing genre determined by the singing genre determining means.

  Thereby, when the guide vocal sound is generated by the artificial voice by the guide vocal generating means, it is possible to generate the guide vocal sound having a more optimal voice mode that matches the singing preference of the specific singing user. As a result, the convenience can be further improved.

  In order to achieve the above-mentioned object, the third aspect of the invention relates to post transmission means for transmitting post song data, singing melody score information, and lyric data related to music created by a post user, and the post transmission means. And at least the posted music data, the score information, and the lyric data as post data, and a singing history storage unit that stores singing history information of each of the plurality of singing users. The posted music performance method executed by the posting processing system having the post song data and the lyric data included in the posted data stored in the post storage means based on an instruction of a specific singing user Based on the posted music acquisition procedure acquired from the posting storage means and the instructions of the specific singing user, Based on the singing voice determination procedure for determining whether or not the corresponding singing voice data is included in the posted data including the posted music data and the specific singing user's instruction, the corresponding specific singing Based on the singing history acquisition procedure for acquiring the singing history information of the user from the singing history storage means and the singing history information acquired in the singing history acquisition procedure, It is determined that the singing voice data is not included in the posting data in the melody knowledge determination procedure for determining the presence or absence of the knowledge of the specific singing user with respect to the singing melody, and the melody voice data is included in the posted data. When it is determined that there is no knowledge of the specific singing user for the singing melody of the posted music data in the knowledge determining procedure, Based on the musical score information and the lyric data included in the post data stored in the post storage means, a guide vocal generation procedure for generating a corresponding guide vocal voice by artificial voice, and the guide vocal generation procedure And a voice / music playback procedure for playing back the guide vocal voice together with the posted music data acquired in the posted music acquisition procedure.

Display the corresponding telop.

  The communication control unit 110 controls information communication with the remote controller 35 and the host server 20.

  The remote controller 35 is an operation terminal for a user to perform various operations such as a reservation operation for karaoke music with a plurality of keys and switches.

<Host server>
The host server 20 includes information storage means (not shown) composed of, for example, a large capacity storage device. In addition, the host server 20 functionally includes a singing history storage unit 21, a post data storage unit 22, and a viewing presence / absence determination unit 24. Detailed functions of these functional units will be described later.

<Processing sequence>
In the above, in the communication karaoke system 1 provided with the karaoke apparatus 10 of the present embodiment, an original song for singing personally created by a user (hereinafter referred to as “posting user” as appropriate) is used, for example, using the external terminal P. By posting to the host server 20, other users (hereinafter referred to as “singing users” as appropriate) can browse (for example, singing) in the karaoke apparatus 10. The details will be described below with reference to the sequence diagram of FIG.

<Music submission>
That is, when the posting user creates his or her own original music, post data relating to the created music is transmitted from the external terminal P to the host server 20 (step SP1). The posted data includes music data of the music (= corresponding to posted music data, for example, MIDI data), musical score information of singing melody (melody), and lyrics data. In addition, this contribution data may include the singing voice data of the music data by the posting user's own singing. Note that the external terminal P that executes this step SP1 functions as a posting transmission means described in each claim. The host server 20 that has received the posted data assigns a song ID, which is unique identification information, to the posted data and stores it in the posted data storage unit 22. The posted data storage unit 22 functions as posted storage means described in each claim.

<Data structure>
FIG. 3 shows an example of the data structure of the posted data stored in the posted data storage unit 22 of the host server 20. In FIG. 3, in this example, the post data 220 includes a song ID (or a song name or the like) 221 given as described above, the song data 224 as performance data, and a song. Music score information 222 of melody (melody) and lyrics data 223 are provided.

  The song ID 221 is placed as a header of the post data 220. The music data 224 is composed of, for example, MIDI data as described above, and is downloaded from the host server 20 and stored in the large-capacity storage device 103 of the karaoke apparatus 10 as will be described later, and then read out to read the sound source 106 and the like. Can be emitted from the speaker 108 as sound.

  The lyric data 223 is based on the original lyrics of the posting user as described above, and is downloaded from the host server 20 and stored in the large-capacity storage device 103 in the same manner as described above. 109 can be displayed. In this example, the lyric data contains the lyrics that say "If you don't even say that word, I'm sure a little more ...".

  As described above, the musical score information 222 represents an original singing melody (melody) created by the posting user, and is typically represented by a staff notation as shown.

  In this example, the lyrics data 223 and the score information 222 are incorporated in the same file as the music data 224, but the present invention is not limited to this. That is, the lyrics data 223 and the score information 222 may be configured as a separate file from the music data 224 and may be associated with the same music title.

<Possibility of singing difficulty>
At this time, as described above, the posting data 220 as described above is the original work of the posting user. Therefore, even if the singing user tries to sing along with the reproduction of the music data 224, it remains as it is. In this case, the melody line is not known and singing may be difficult. Therefore, in this embodiment, a guide vocal is artificially generated based on the score information 222.

<Downloading songs submitted by singing users>
That is, for example, by a suitable operation on the remote control 35 of the karaoke device 10 by a specific singing user, a list of posted music pieces in which the posted data is stored in the posted data storage unit 22 of the host server 20 is acquired by the remote control 35. Is displayed (step SR1). When a specific posted music is reserved by an appropriate operation of the singing user with the remote control 35 (step SR2), the user ID of the singing user (logged in at this time) and the above of the specific posted music The song ID 221 is transmitted to the apparatus main body 100. When the music ID 221 of the specific posted music is acquired by the control unit 101 of the apparatus main body 100, a request for downloading the posted music including the music ID is transmitted from the control unit 101 to the host server 20 (step SC1). . In response to this, the host server 20 searches the posted data storage unit 22 for posted data including the song ID, and the posted data 220 (music data 224, lyrics data 223, score information having the song ID). 222 is transmitted from the host server 20 to the karaoke apparatus 10, is acquired by the control unit 101, and is stored in the mass storage device 103 (step SS2). This step SS2 corresponds to the posted music acquisition procedure described in each claim, and the control unit 101 that acquires the posted data 220 as described above in this step SS2 functions as the posted music acquisition means described in each claim. .

<Reference to singing history>
By the way, even if it is the original music by the posting user as described above, if the singing user has already sung once or has seen others singing, the generation of the above guide vocal There is no need to do. Therefore, as described above, the singing user himself / herself has sang or has seen other people's singing (this case is referred to as “viewed history of posted music” as appropriate), or the singing user himself / herself The singing history of the singing user is referred to ascertain whether or not he / she has sang or has ever seen another person's singing (this case is referred to as “no viewing history of posted music” as appropriate). . That is, the singing history information of each of a plurality of users is stored in advance in the singing history storage unit 21 of the host server 20. Then, after the posting data 220 is obtained in step SS2, a request for a viewing result is transmitted from the control unit 101 of the karaoke apparatus 10 to the host server 20 in step SC2. Note that the user ID of the specific singing user is attached to this request (see step S120 in FIG. 4 described later).

  Upon receiving the request, the host server 20 performs viewing presence / absence determination processing (step SS3). FIG. 4 is a flowchart showing details of the viewing presence / absence determination processing.

  In FIG. 4, first, in step S100, the host server 20 is based on the user ID of the specific singing user received from the control unit 101 of the karaoke apparatus 10 in step SC2, and the singing history storage unit 21 (in the singing history storage unit). The singing history of the singing user stored in (equivalent) is acquired.

  An example of the singing history of each singing user stored in the singing history storage unit 21 is shown in FIG. In this example, the song ID of a song that has been sung and the genre of the song are stored in association with the user ID of each singing user. In the example shown in the figure, the user “AAA” has a music piece with ID “555” (genre: pop), a music piece with ID “666” (genre: pop), a music piece with ID “999” (genre: reggae), Singing in the past. The user “BBB” has sung in the past the music with the ID “111” (genre: pop), the music with the ID “222” (genre: enka), and the music with the ID “444” (genre: enka). ing. The user “CCC” has a song with ID “111” (genre: pop), a song with ID “222” (genre: enka), a song with ID “333” (genre: POP), and an ID “777”. The song (genre: POP) has been sung in the past. The user “DDD” has sung the song with the ID “888” (genre: reggae) and the song with the ID “999” (genre: reggae) in the past.

  In addition, said step S100 is corresponded to the song history acquisition procedure as described in each claim, and the host server 20 which performs this step S100 functions as a song history acquisition means as described in each claim.

  Thereafter, the process proceeds to step S110, and the host server 20 determines whether or not the singing history acquired in step S100 includes the song ID received in step SC1 by the viewing presence / absence determination unit 24. If the song ID is included, the determination is satisfied (S110: YES), and the process proceeds to step S140 described later. If the song ID is not included, the determination is not satisfied (S110: NO), and the process proceeds to step S120.

  In step S120, the host server 20 uses the viewing presence / absence determination unit 24 to obtain the user IDs (obtained in step SC2) of other singing users who have logged in together with the specific singing user at the predetermined condition (at step SC120). The other singing user determines whether or not the posted song with the song ID received in step SC1 has been sung. If the posted music is sung, the determination is satisfied (S120: YES), and the process proceeds to step S140 described later. If the posted music is not sung, the determination is not satisfied (S120: NO), and the process proceeds to step S130.

  In addition, with the said predetermined conditions which extract the other above-mentioned song user, each user's song history information is memorize | stored in the song history memory | storage part 21 of the host server 20, for example. The singing history information includes the time information when the user logged in and the time information when the user logged out (the time period from login to logout or the time length based on one of the login and logout times) and the singing karaoke apparatus 10. Information to be specified (for example, serial number, IP address, etc.) is also included. The host server 20 uses the same karaoke device as the karaoke device that the specific user sang in the time period from login to logout, and logs in another user who has logged in in the same time zone together with the specific singing user. Extract as other singing users.

  In step S130, the host server 20 saw that the other singing user sings the posted music without the specific singing user singing the posted music by the viewing presence / absence judging unit 24. The viewing history of the specific singing user with respect to the posted music is “no viewing history”. Then, this routine ends.

  On the other hand, in step S140, the host server 20 causes the viewing presence / absence determination unit 24 to sing the posted song by the specific singing user or the other singing user sings the posted song. The viewing history of the specific singing user with respect to the posted music is assumed to be “with viewing history”. Then, this routine ends. In addition, the said step S130 and step S140 are equivalent to the melody knowledge determination procedure of each claim, and the host server 20 which performs these steps S130 and S140 functions as the melody knowledge determination means described in each claim. .

  Returning to FIG. 2, when step S130 or step S140 is completed, the host server 20 indicates the determination result obtained in step S130 or step S140, that is, “no viewing history” or “with viewing history” as a karaoke device. 10 (step SS4).

  The control unit 101 of the karaoke apparatus 10 that has received the determination result “no viewing history” or “with viewing history” executes a guide vocal provision process based on the reception result (step SC3). FIG. 6 is a flowchart showing details of the guide vocal imparting process.

  As described above, the posted data 220 created by the posting user includes the song data 224, the score information 222, and the lyrics data 223 of the posted song, and the singing voice of the song data based on the singing of the posting user himself / herself. May contain data. In such a case, since the melody line can be confirmed as it is based on the singing voice data, it is not necessary to generate a guide vocal voice. Therefore, in FIG. 6, first, in step S200, the control unit 101 determines whether or not the singing voice data is included in the post data 220 received from the host server 20 in step SS2. For example, when each posting data 220 is flagged as to whether or not singing voice data is included, this determination method may be checked. Alternatively, it may be determined by performing known audio frequency detection on the post data 220. This step S200 corresponds to a singing voice determination procedure described in each claim, and the control unit 101 that executes this step S200 functions as a singing voice determination unit described in each claim.

  Then, based on the determination result “no viewing history” or “with viewing history” received from the host server 20 in step SS4 and the determination result of the presence or absence of singing voice in step S200 in step S201, the control unit 101 Determines whether the determination result received from the host server 20 is “no viewing history” and the determination result in step S200 is “no singing voice”. If the determination result is “no viewing history” or “no singing voice”, the determination is satisfied (S201: YES), and the process proceeds to step S220. If there is a determination result of either “viewing history” or “singing voice is included”, the determination is not satisfied (S201: NO), this routine is terminated, and the process proceeds to step SC4 in FIG. Move.

  When the determination result is “no viewing history” or “no singing voice”, singing difficulty due to the unknown melody line occurs. Therefore, in this case, in order to generate a guide vocal voice, the control unit 101 transmits a request for the singing genre of the specific singing user to the host server 20 in step S220. As shown in FIG. 5, the genre of music sung by each user is also recorded in the singing history stored in the singing history storage unit 21 of the host server 20. The host server 20 that has received the request for the singing genre refers to the genre recorded in the singing history and determines the singing genre of the requested specific singing user (step SS5 in FIG. 2). In this determination, when the songs sung by the user are aggregated for each genre, the genre with the largest number of songs may be set as the singing genre of the user. In the example shown in FIG. 5, since the user “AAA” sings the genre: POP most frequently, the singing genre is “POP”. Since the user “BBB” sings the genre: Enka song most, the singing genre is “Enka”. Since the user “CCC” sings the genre: POP most frequently, the singing genre is “POP”. Since the user “DDD” sings the genre: reggae song most, the singing genre is “reggae”. In addition, the host server 20 which performs said step SS5 functions as a singing genre determination means as described in each claim. The determination of the singing genre may be executed by the host server 20 as needed, and the determination result may be stored.

  Thereafter, in step S230, the control unit 101 acquires the singing genre of the specific singing user transmitted from the host server 20 to the karaoke apparatus 10 after being determined as described above. Thereafter, the process proceeds to step S240.

  In step S240, parameters for synthesizing the guide voice vocal for the song of the specific singing user are determined based on the singing genre acquired in step S230. This determination is performed using, for example, the table shown in FIG. In the example shown in FIG. 7, as the parameter, the volume is relatively increased (represented by “UP”) or the volume is relatively increased in each of the high frequency range, middle frequency range, low frequency range, and heavy low frequency range. The sound quality is set for each singing genre by selecting whether to decrease (represented by “DOWN”) or not increase or decrease (represented by “no UP / DOWN”). In this example, for example, in the case of the singing genre “POP”, the sound quality is set such that the volume is increased in the high range, the volume is not increased or decreased in the middle range, the volume is not increased or decreased in the low range, and the volume is increased in the deep bass. The In the case of the singing genre “enka”, the sound quality is set such that there is no increase / decrease in volume in the high range, volume increase in the middle range, no increase / decrease in volume in the low range, and volume decrease in heavy bass. In the case of the singing genre “reggae”, the sound quality is set such that there is no volume increase / decrease in the high sound range, there is no volume increase / decrease in the middle sound range, the sound volume is increased in the low sound range, and the sound volume is increased in the heavy bass sound. Thereafter, the process proceeds to step S250.

  In step S250, the control unit 101 uses the artificial sound source provided in the sound source 106 according to the musical score information 222 and the lyrics data 223 acquired in step SS2, and is further determined in step S240. According to the parameters, the guide vocal sound of the posted music is synthesized. The guide vocal voice generated by this synthesis is stored in the mass storage device 103, for example. This step S250 corresponds to a guide vocal generating procedure described in each claim, and the control unit 101 that executes this step S250 functions as a guide vocal generating unit described in each claim.

  Returning to FIG. 2, when the guide vocal imparting process in step SC <b> 3 is completed as described above, the music data 224 of the posted music is read from the large-capacity storage device 103 based on the control of the control unit 101 and the sound source 106. The guide vocal voice synthesized in step S250 is read out from the mass storage device 103 and reproduced in synchronism with the reproduction (step SC4). In other words, the posted music is played with a guide vocal. At this time, lyrics display by the lyrics data 223 is performed by the display unit 109. This step SC4 corresponds to the voice / music reproduction procedure described in each claim, and the control unit 101 that executes this step SC4 functions as the voice / music reproduction means described in each claim.
