An input reception is performed by identifying a certain performer, and the music selection number of the selected performance song and the user ID of the performer who is the main music selection unit are associated and registered in the reserved music table. When the performance music (reserved music) registered in the reserved music table is in the performance order, the performance control means 92 starts the karaoke performance of the performance music and performs the karaoke performance ( The performance control is performed by identifying who the performance subject is (for example, which user ID corresponds to the performer).

  The determination control means 94 performs the karaoke performance based on the voice information input by the microphone 40 which is a voice input device from the predetermined relationship when performing the karaoke performance by the performance control means 92 having a predetermined user as a performer. It is determined that the performance cannot be continued midway. In other words, it is determined that the player (singer) who is performing the karaoke performance at the present time cannot sing well before the end of the performance. This inability to continue karaoke performance is not necessarily determined when the singing is no longer complete, such as when a singing that is significantly out of tune continues, or when the singing is broken in some places Also determined. Specifically, the determination control means 94 determines that karaoke performance cannot be continued as follows.

  Preferably, the determination control means 94 evaluates the karaoke performance based on the pitch of the voice information input by the microphone 40 from a predetermined relationship, and the karaoke performance is halfway based on the evaluation result. It is determined that it is impossible to continue. For example, a performance output by the synthesizer 38 based on audio information input by the microphone 40 and converted into a digital signal by the A / D converter 41 and performance information (MIDI data) read from the music database 66. The information is compared, and scoring is performed based on the relative deviation between the basic pitch such as a melody and the pitch extracted from the input voice, the absolute volume of the voice, and the like. This scoring is preferably performed by continuously storing the audio information converted into a digital signal by the A / D converter 41 in the storage device such as the RAM 54 from the start to the end of output of the target performance music piece. In addition, it is periodically executed at predetermined timings (for example, a short interval such as once every 0.5 seconds) while the target performance music is output, that is, from the start to the end of the performance. As the scoring mode, for example, scoring may be performed numerically, such as how many points out of a thousand points, or acceptable (evaluation is equal to or higher than a predetermined threshold) or impossible (evaluation is predetermined). It may be as simple as determining which one falls below (the threshold value below). And when the result of the said scoring is below a predetermined criterion, it is determined that the target karaoke performance cannot be continued midway.

  Further, the determination control means 94 preferably has a predetermined volume of audio information input by the microphone 40 in a singing section of the target performance piece (a section where lyrics to be uttered by the performer exist). When the state of being less than the threshold value continues for a predetermined time or more, it is determined that the karaoke performance cannot be continued midway. For example, the volume (sound pressure level) of the voice information input by the microphone 40 and converted into a digital signal by the A / D converter 41 is detected, and a state in which the volume is less than a predetermined threshold is a specified time. When it continues (for example, about 10 to 20 seconds), it is determined that the karaoke performance cannot be continued midway. In other words, when the state in which the sound input from the microphone 40 is minute continues for the specified time or longer, it is determined whether the karaoke performance cannot be continued. It should be noted that this determination is not performed in the interlude section (the section in which there is no lyrics to be uttered by the performer) as the target performance piece.

  Further, the determination control means 94 preferably determines that the karaoke performance cannot be continued midway based on video information captured by the digital camera 61. For example, a state in which a performer to be determined sings (for example, the performer is determined by an infrared signal of the microphone 40) is photographed by the digital camera 61, and the performer's face is photographed based on the photographed video information. Perform image analysis in the section. Then, as a result of the image analysis, a predetermined time in which a state where the performer's mouth is closed (or the mouth opening is small) in spite of being a section to be sung in the target performance piece is predetermined. If it continues, it is determined that the karaoke performance cannot be continued midway.

  Further, the determination control means 94 preferably performs such determination when a predetermined condition is satisfied even when it is determined that the karaoke performance cannot be continued by the mechanism as described above. Not performed. In other words, the karaoke performance continuation determination is not executed. For example, if there is only one player who has been authenticated by the authentication control means 90, that is, if the current player is performing a karaoke performance alone, the karaoke performance continuation determination is not performed. Moreover, the evaluation result of the past performance evaluation corresponding to the present performer stored in the SNS database 86 via the communication line 18 is acquired, and the average (average score) of the evaluation results is determined in advance. If it is less than the threshold, the karaoke performance continuation determination is not performed because it can be regarded as a poor singer regardless of what song is sung rather than remembering the performance song related to the determination. .

  When the determination by the determination control unit 94 is made, the presentation control unit 96 shown in FIG. 4 presents other performer candidates who can play the musical piece related to the determination. Preferably, other performances capable of playing the performance music (the performance music determined to be unable to continue karaoke performance midway) from among the performers who have been authenticated by the authentication control means 90. Select and present candidates. The performer candidate refers to a performer who has a high probability of performing (singing) the performance music according to the determination, and the performance music may not necessarily be actually played. Specifically, the presentation control means 96 selects and presents such a player candidate as follows.

  The presentation control unit 96 preferably acquires information stored in the SNS database 86 corresponding to each player who has been authenticated by the authentication control unit 90, and based on the acquired information, the presentation control unit 96 acquires the information stored in the SNS database 86. Other performer candidates who can perform the performance piece according to the determination are selected and presented from the players who are authenticated by login. Preferably, at least one of the performance history, the eighteenth tune, and the performance reservation corresponding to each performer stored in the SNS database 86 is read out, and among the performers who have been authenticated for login based on the information. Then, other performer candidates who can perform the music piece according to the determination are selected and presented. For example, if there is a player whose performance music is included in the music selection history, that is, a music player who has selected or performed the performance music in the karaoke apparatus 16 in the past, that player is selected as the other performer candidate. select. If there is a performer who registers the target performance as an eighteenth piece, the performer is selected as the other performer candidate. Further, when there is a performer who has reserved a performance for the target musical piece, the performer is selected as the other performer candidate. Here, the other performers to be selected may not necessarily be singular (single). However, when selecting a single performer, for example, a performance in which the target performance is included in the music selection history. The player who has reserved the performance over the performer has priority, and the performer registered as the eighteenth song has priority over the performer who has reserved the performance of the target performance as the other performer candidate select.

  In addition, the presentation control unit 96 is preferably the same as the performance song according to the determination from among the players who have been authenticated by the authentication control unit 90 based on the information related to the album in which the performance song is recorded. A performer who has played a musical piece recorded in the album in the past is selected and presented as the other performer candidate. In other words, if there is a performer whose performance song recorded in the same album as the target performance song is included in the music selection history, that performer is selected as the other performer candidate. Preferably, among the performers who have been logged in by the authentication control means 90, cover songs (performed songs with the same performance but different singers) are played in the past. A performer who has performed is selected as the other performer candidate and presented. In other words, when there is a performer whose cover song of the target performance song is included in the music selection history, the performer is selected as the other performer candidate.

  Further, the presentation control means 96 is preferably another player who can perform the performance piece according to the determination from the login-authenticated players based on the video information photographed by the digital camera 61. Select and present candidates. For example, by analyzing the image information captured by the digital camera 61, the player's face image included in the image information is recognized, and for example, a player who is detected to move his / her mouth (lips) is detected. If it exists, it is considered that the target performance piece is humming, and the performer is selected as the other performer candidate.

  Further, in the aspect in which the SNS database 86 stores a CD previously purchased by the performer corresponding to each performer, music information by download sales, incoming melody information of a mobile phone, etc., the presentation control means Preferably, when information relating to the music purchased by each performer in the past includes information corresponding to the performance piece according to the determination, the performer is set as the other performer candidate. select. That is, the purchase history of a single CD corresponding to the performance song according to the determination, the purchase history of the album CD containing the performance song, the download purchase history of the performance song, or the download purchase of the incoming melody information corresponding to the performance song If there is a player with a history or the like, the player is selected as the other player candidate. In addition, when the selected performer candidate is registered in the SNS database 86 as the friend of the original performer, the date registered as the friend is within a predetermined period (the day is still a shallow day as a friend). Therefore, the player who is registered as the friend is selected as the other player candidate.

  In addition, the presentation control unit 96 preferably relates to the determination when a predetermined condition is satisfied after the determination by the determination control unit 94 is performed and the other player candidates are presented. Make a presentation to encourage the original performer to return to karaoke. That is, the player at the time point when the determination control means 94 determines that the karaoke performance of the target musical piece cannot be continued midway is urged to return to the karaoke performance (resumption of singing). Make a presentation. Preferably, in response to the start of the chorus of the performance music according to the determination, a presentation for prompting the original performer to return to karaoke performance is performed. In other words, presentation is made to encourage the original performer to return to the karaoke performance in tandem with the performance of the chorus, which is often possible to return to the karaoke performance.

  When the other player candidate is selected as described above, the presentation control means 96 makes a presentation for prompting the player candidate to perform karaoke performance. Preferably, a display for prompting the player candidate to perform karaoke performance is performed on the video display device 30 via the video output control unit 32 or the like.

In the above control, SA1 to SA6 correspond to the operation of the authentication control means 90.

  FIG. 12 is a flowchart for explaining a main part of the help player presentation control by the CPU 50 of the karaoke apparatus 16 and is repeatedly executed at a predetermined cycle.

  First, at SB1, it is determined whether or not the karaoke performance of a predetermined performance music is started, for example, in the order of performance music performance stored at the top of the reserved music table. If the determination at SB1 is negative, the routine is terminated. If the determination at SB1 is affirmative, the musical composition data of the musical composition at the start of performance is stored in the musical composition database 66 at SB2. The synthesizer 38 starts performance output corresponding to the performance information in the music data, and also starts display control of lyrics character video corresponding to the lyrics information in the music data. Next, in SB3, whether or not the karaoke performance is not able to be continued midway based on the audio information input from the microphone 40 from a predetermined relationship when the performer performs the karaoke performance of the performance music at the present time. Is judged. If the determination at SB3 is negative, the processing from SB6 onward is executed. If the determination at SB3 is affirmative, at SB4, other performers who can perform the musical piece according to the determination at SB3. A candidate is selected. Next, in SB5, a video showing another performer candidate selected in SB4 is presented (displayed) on the video display device 30, the touch panel display 22a of the electronic quick sample device 22, or the like. Next, at SB6, it is determined whether or not the karaoke performance by the synthesizer 38 or the like has reached the vicinity of the chorus of the performance song related to the determination of SB3. When the determination of SB6 is negative, the processing after SB8 is executed, but when the determination of SB6 is affirmative, at SB7, the original performer's karaoke performance related to the determination of SB3 is performed. A video prompting the return is presented (displayed) on the video display device 30, the touch panel display 22a of the electronic quick sample device 22, or the like. Next, in SB8, it is determined whether or not the karaoke performance is finished, for example, when all the performance times corresponding to the performance information in the music data have elapsed. When the determination of SB8 is denied, the processing after SB3 is executed again. However, when the determination of SB8 is affirmed, after the karaoke performance is ended by singing to the end, This routine is terminated. In the above control, SB1, SB2, SB7 to SB9 are the operations of the performance control means 92, SB3 is the operation of the determination control means 94, and SB4, SB5 and SB7 are the operations of the presentation control means 96, respectively. Correspond.

  As described above, according to the present embodiment, when the performer performs the karaoke performance of the performance music, the karaoke performance is halfway based on the voice information input by the microphone 40 which is a voice input device from a predetermined relationship. If the determination control means 94 (SB3) for determining that it has become impossible to continue, and the determination by the determination control means 94 are performed, other performer candidates who can play the performance music according to the determination are presented. Since the presentation control means 96 (SB4, SB5, and SB7) is provided, the time when the singing is not performed when the performer cannot sing to the end and the karaoke performance stops midway. It is possible to suitably suppress the occurrence of an occurrence or interruption of the performance before rusting. That is, it is possible to provide the karaoke apparatus 16 that prevents the atmosphere of the place from being broken when the performer cannot sing along the way.

  The karaoke device 16 is capable of transmitting and receiving information to and from the SNS database 86 that stores individual information for each player who performs karaoke performance using the karaoke device 16. Authentication control means 90 (SA1 to SA6) for performing login authentication of the performer participating in the use of the karaoke device 16 according to the identification information input by the electronic quick sample device 22 or the like, and the presentation control The means 96 acquires the information stored in the SNS database 86 corresponding to each performer authenticated by the authentication control means 90, and based on the acquired information, the players authenticated by the login. Since other performer candidates who can perform the performance piece according to the judgment are selected and presented from among them, each player is individually stored. By referring to the information, it can be suitably selected to provide the other player candidates that can play the music piece continuation of the performance could not.

  The SNS database 86 stores at least one of a performance history, an eighteenth tune, and a performance reservation for each player who performs a karaoke performance using the karaoke device 16. , Another performer candidate who can perform the performance piece according to the determination from among the performers who have been authenticated by the login based on at least one of the performance history, the eighteenth piece, and the performance reservation stored in the SNS database 86 Therefore, it is possible to select a performance piece that cannot be continued by referring to information such as the performance history, eighteenth piece, and performance reservation that are individually stored for each performer. Other performer candidates who can perform can be suitably selected or presented in a practical manner.

  In addition, the presentation control unit 96 may store a performance song recorded in the same album as the performance song according to the determination from among the players who have been authenticated by the login based on information on the album in which the performance song is recorded. In order to select and present a performer who has played in the above as a candidate for the other performer, by referring to the information about the album in which the performance song that has been impossible to continue is recorded, Other performer candidates who can play the musical piece can be suitably selected or presented in a practical manner.

  The determination control means 94 evaluates the karaoke performance based on the pitch of the voice information input from the microphone 40 from a predetermined relationship, and the karaoke performance is continued halfway based on the evaluation result. Since it is determined that it has become impossible, it can be determined in a practical manner that it is impossible for the performer to continue the karaoke performance at the present time.

  In addition, the determination control means 94 is unable to continue the karaoke performance when the volume of the sound information input by the microphone 40 is less than a predetermined threshold for a predetermined time or more. Therefore, it is possible to determine in a practical manner that it is impossible to continue the karaoke performance by the performer at the present time.

  In addition, after the determination by the determination control unit 94 is performed and the other performer candidates are presented, the presentation control unit 96 is the original player related to the determination when a predetermined condition is satisfied. Therefore, when the player can return to the karaoke performance, the original player can preferably restart the karaoke performance.

  Further, since the presentation control means 96 makes a presentation prompting the original performer to return to the karaoke performance in response to the start of the chorus of the performance song related to the determination, the return to the karaoke performance is not possible. The original performer can preferably resume the karaoke performance in tandem with the chorus performance that often becomes possible.
