  By the way, there is a case where a user visits a karaoke store and decides what music to sing first. In particular, in a scene in which karaoke is enjoyed by a group of multiple people, whether or not the first selected music can be sung in a stable manner greatly affects the atmosphere of the subsequent place. For these reasons, the user often becomes cautious about selecting a song that can be sung as stably as possible for a song that is first sung after visiting a karaoke store, and it often takes time to select a song.

  With respect to such a problem, it is conceivable that a song that has been successfully sung in the past can be selected with reference to a song history in which a user has sung a song or a scoring result. However, just because the score of the scoring result recorded in the singing history is simply high, it does not necessarily indicate that the singing can be stably performed throughout the music. For example, even if the overall evaluation based on the melody evaluation criteria is simply high, the breakdown may be an unstable song in which a high score period and a low score period are mixed. In such a case, even if the user intends to select a song that can be sung well on the basis of the high score in the past scoring results, an unstable singing where the part that can be sung well and the part that is not so confused is mixed up It is possible that the atmosphere of the venue will be changed and worsened. As described above, it is difficult to determine whether or not the music of the place can be appropriately maintained based on the singing history such as the score of a simple scoring result, which music should be selected from his own songs.

  The present invention has been made to solve the above problems. The purpose is to provide a technique for assisting the user in selecting music that can be stably sung by the user.

  A karaoke system according to an aspect of the present invention includes a log-in means for accepting a login of a karaoke user, a reservation accepting means for accepting a music performance reservation in association with each logged-in user, and a performance reservation accepted from the user And a performance means for performing the music. The karaoke system further includes storage means, scoring means, stability evaluation means, singing history storage means, ranking means, and singing history presentation means.

  The storage means stores singing history information for each user. Singing history information is information showing the history about the singing performed by the user in the past. The scoring means calculates an evaluation score for each period obtained by dividing the music played by the performance means into a plurality of periods. The evaluation score is a score calculated by evaluating the skill of the user's singing based on the evaluation standard regarding the melody. The stability evaluation means specifies the singing stability based on the fluctuation of the evaluation score for each period calculated by the scoring means in the performance of one piece of music. The stability is a value obtained by evaluating the stability of the entire singing performance. The stability of the singing is evaluated as higher as the evaluation score changes less, and as the change increases, the singing stability is evaluated lower.

  The singing history storage means associates the identification information of the user who performed the singing, the information of the music piece played in the singing and the stability specified by the stability evaluation means for the singing. Is stored in the storage means as singing history information relating to the singing. The ranking means ranks the history related to individual singing history information for each user in descending order of stability based on the singing history information stored in the storage means.

  The singing history presentation means receives recommendation information based on the singing history information corresponding to the user who makes a performance reservation from among the singing history information stored in the storage means when the reservation reception means accepts the performance reservation of the music. Presented to users who make performance reservations. This recommendation information corresponds to the order of the song sung in the past represented by the singing history information corresponding to the user who reserves the performance, and the ranking of the singing history information of the user by the ranking means. Information to be added.

  According to the present invention, instead of deciding a song to be recommended to the user based only on the evaluation score related to the melody, the recommendation information obtained by ranking past songs in terms of the stability of the song based on the degree of fluctuation of the evaluation score is used. Can be presented to the person. The user can know the music that can be stably sung by referring to the presented recommendation information, and can be a powerful clue for selecting the music to sing.

  Moreover, it is good to comprise as another form of the karaoke system which concerns on this invention as follows. That is, the storage unit stores singing history information further including information indicating the time when the music related to the singing history information is played. Then, the ranking means ranks the singing history information included in a predetermined range from the newest time when the performance was performed in the order of stability. In this way, it is possible to present recommended information with content that matches the current state of the user.

  As another form of the karaoke system according to the present invention, the singing history presenting means recommends corresponding to the user who makes a performance reservation when accepting the first performance reservation after the user logs in in the reservation receiving means. It may be configured to present information. By doing in this way, when a user visits a karaoke store and decides what music to sing first, it is possible to present powerful clues for selecting music that can be stably sung.

  Further, when the user performs the next performance reservation after the first singing, the following is preferable. In other words, the singing history presenting means uses the evaluation score calculated in the performance of the music related to the previous performance reservation when receiving the subsequent performance reservation of the user after the music related to the first performance reservation is played. Depending on the quality, the recommended information that ranks the user's singing history information in order of the degree of stability or the recommended information that ranks the singing history information of the user in the order of the evaluation score for one song is presented. To do. By doing in this way, for example, if a high score could not be obtained in the previous song, the order based on the evaluation score is presented so that it can be used as a reference for aiming for a high score this time. Depending on the result of singing, the music to be sung in a flexible manner can be recommended.

  Next, a karaoke apparatus according to an aspect of the present invention includes a login unit that accepts a login of a karaoke user, a reservation accepting unit that accepts a performance reservation for a song associated with each logged-in user, and an acceptance from the user. Performance means for performing music according to the performance reservation. The karaoke apparatus further includes scoring means, stability evaluation means, singing history storage means, ranking means, and singing history presentation means.

  The scoring means is an evaluation score that is a score calculated by evaluating the skill of the user's singing based on the evaluation criteria for the melody for each period obtained by dividing the musical piece played by the musical performance means into a plurality of periods. Is calculated. The stability evaluation means specifies the stability, which is a value obtained by evaluating the stability of the entire song in the performance of the music based on the fluctuation of the evaluation score of each period calculated by the scoring means in the performance of one music To do.

  The singing history storage means associates the identification information of the user who performed the singing, the information of the music piece played in the singing and the stability specified by the stability evaluation means for the singing. Is stored in a predetermined storage means as singing history information relating to the singing. The ranking means ranks the history related to individual singing history information for each user in descending order of stability based on the singing history information stored in the storage means.

  The singing history presentation means receives recommendation information based on the singing history information corresponding to the user who makes a performance reservation from among the singing history information stored in the storage means when the reservation reception means accepts the performance reservation of the music. Presented to users who make performance reservations. This recommendation information corresponds to the order of the song sung in the past represented by the singing history information corresponding to the user who reserves the performance, and the ranking of the singing history information of the user by the ranking means.

[Explanation of singing score and stability]
Specific examples of the singing score and stability derived when the karaoke apparatus 10 plays the music will be described with reference to the examples of FIGS. The graphs (a) to (e) in FIG. 2 are calculated based on the evaluation reference data of each song when one user sings five songs A, B, C, D, and E. It shows the transition of the score for the period. In each graph (a) to (e), the vertical axis represents the score of the period score, and the horizontal axis represents the performance period. In the example of FIG. 2, it is assumed that each musical piece is divided into eight performance periods, but the present invention is not limited to this.

  As illustrated in FIG. 2, for example, as shown in graphs (c) and (d), the period score may be stabilized almost constant throughout the performance, and graphs (a) and (e) As shown, the period score may fluctuate up and down every performance period. When calculating the singing score for an entire song by averaging the period scores, even if the singing scores are the same level for a plurality of songs, it is said that the stability of the singing is when the fluctuation in the period scores is large and small The impression of the participants who listened to the song from the viewpoint is considered to be very different.

  FIG. 3 shows a singing score and stability derived from the entire song for the singing examples represented by the graphs (a) to (e) in FIG. The table of the code | symbol (a)-(e) of FIG. 3 shows the period score and period stability for every performance period about each song example corresponding to each graph (a)-(e) of FIG. Represents the singing score and stability. The period stability is a value representing the stability of singing for each performance period. The stability of the singing is evaluated as higher as the evaluation score changes less, and as the change increases, the singing stability is evaluated lower. Specifically, regarding the period score of a certain performance period, depending on the difference from the period score of the previous performance period, one of the values “O”, “Δ”, “X” in descending order of evaluation. Is given as the period stability in the performance period.

  For example, in the case of FIG. 3, when the difference from the period score of the previous performance period is larger than 10 points, “x” which is the lowest evaluation is given as the period stability in the performance period. In addition, when the difference from the period score of the previous performance period is within 10 points and the period score of the performance period is 70 points or more and less than 80 points, the period stability in the performance period is moderate. “Δ” is given. Also, if the difference from the previous performance period's period score is within 10 points and the performance period's period score is 80 points or more, it is the highest evaluation as the period stability in that performance period. “○” is given. However, when the period score of a certain performance period is less than a predetermined first threshold value (for example, 70 points in the example of FIG. 3), the lowest evaluation as the period stability regardless of the score difference from the previous performance period. A certain “x” is given.

  Moreover, a singing score is the average value of the period scores of all 1 music. The stability is a value that represents the stability of the singing of the entire song, and is calculated by integrating and analyzing the stability of all periods for one song. In the example of FIG. 3, a weight of 3: 2: 1 is set for the evaluation of “◯”, “Δ”, and “×” in the period stability, and “○” is evaluated in the performance period of one song. The value obtained by weighted and summing the duration stability of all the songs is represented so that the score becomes 100 out of 100. The method of calculating the stability of the entire song by integrating the period stability is not limited to the method described above, and various methods can be applied.

  It should be noted in the example of FIG. 3 that the quality of the singing score based on the evaluation reference data does not necessarily match the quality of the singing stability. For example, in the singing example represented by the table of code (e), although the highest singing score is obtained among the singing examples of codes (a) to (e), the stability is the lowest. Yes. Moreover, although the singing score is the same in the singing example of code | symbol (a), (b), (c), it turns out that there exists a big difference with 100-42.8 points about stability. For this reason, when the user selects a song to be sung, the content of the song to be recommended changes from the past singing history depending on whether the singing score or the stability is important.

[Description of history information transmission processing and history information storage processing]
The procedure of history information transmission processing executed by the karaoke apparatus 10 and history information storage processing executed by the management server 30 will be described with reference to the flowchart of FIG. The history information transmission process is a process executed in parallel with the performance process for the music registered in the reservation list in the karaoke apparatus 10. The history information transmission process is a process that is executed each time the management server 30 receives singing history information from the karaoke apparatus 10.

  In S100, the control unit 11 of the karaoke apparatus 10 starts karaoke performance processing based on the music data corresponding to the music whose performance order has arrived in the reservation list. In S102, the control part 11 acquires the audio | voice information showing the user's singing voice | voice input from the microphone 17 according to the performance of a music. This audio information is constituted by, for example, digital audio data obtained by sampling a waveform of a singing voice.

  In S104, the control part 11 calculates the period score showing evaluation of the song corresponding to the performance period performed at present about the audio | voice information acquired in S102. The period score is a score obtained by scoring the skill level of the singing for each performance period obtained by dividing the music into a plurality of pieces. The control unit 11 determines the pitch and pronunciation time of the singing represented by the audio information corresponding to the performance period to be scored, and the reference pitch and pronunciation time represented by the evaluation reference data corresponding to the performance period. The period score is calculated based on the degree of coincidence.

  In S106, the control part 11 performs the period stability determination process which specifies a period stability based on the period score calculated in S104. The period stability is a value obtained by evaluating the singing stability for each performance period. Here, the details of the period stability determination processing in S106 will be described with reference to the flowchart of FIG.

  In S200, the control unit 11 determines whether or not a period score calculated for a performance period (hereinafter referred to as the previous period) immediately before the current performance period (hereinafter referred to as the current period) is stored. When the period score of the previous period is not stored (S200: NO), the control unit 11 proceeds to S202. In S202, the control unit 11 determines that the period stability of the current period is “none”, and ends the present process.

  On the other hand, when the period score of the previous period is stored (S200: YES), the control unit 11 proceeds to S204. In S204, the control unit 11 determines whether or not the period score calculated for the current period is greater than or equal to a predetermined first threshold value. Incidentally, in the example of FIG. 3, it is assumed that the first threshold is set to 70 points. When the period score of the current period is less than the first threshold (S204: NO), the control unit 11 proceeds to S206. In S206, the control unit 11 determines that the period stability of the current period is “x”, which is the lowest evaluation, and ends this process.

  On the other hand, when the period score of the current period is equal to or greater than the first threshold (S204: YES), the control unit 11 proceeds to S208. In S208, the control unit 11 determines whether the absolute value of the difference between the period score of the previous period and the period score of the current period is within a predetermined second threshold. Incidentally, in the example of FIG. 3, it is assumed that the second threshold is set to 10 points. When the absolute value of the score difference between the previous period and the current period is larger than the second threshold (S208: NO), the control unit 11 proceeds to S206. In S206, the control unit 11 determines that the period stability of the current period is “x”, which is the lowest evaluation, and ends this process.

  On the other hand, when the absolute value of the score difference between the previous period and the current period is within the second threshold (S208: YES), the control unit 11 proceeds to S210. In S210, the control unit 11 determines whether or not the period score for the current period is equal to or greater than a predetermined third threshold value. Incidentally, in the example of FIG. 3, it is assumed that the third threshold is set to 80 points. When the period score of the current period is less than the third threshold (S210: NO), the control unit 11 proceeds to S212. In S212, the control unit 11 determines that the period stability of the current period is “Δ”, which is a moderate evaluation, and ends the present process.

  On the other hand, when the period score of the current period is greater than or equal to the third threshold (S210: YES), the control unit 11 proceeds to S214. In S214, the control unit 11 determines that the period stability of the current period is “◯”, which is the highest evaluation, and ends this process.

  Returning to the flowchart of FIG. In S108, the control unit 11 stores the period score of the current period calculated in S104 and the period stability of the current period specified in S106 in a predetermined storage area. In S110, the control unit 11 determines whether or not the music performance has ended. When the performance of the music has not ended (S110: NO), the control unit 11 returns to S102, and repeats the processes of S102 to S108 for the next performance period. On the other hand, when the performance of the music is finished (S110: YES), the control unit 11 proceeds to S112.

  In S112, the control part 11 calculates the singing score of the whole music played this time. Specifically, an average value of the period scores of the entire song stored in a predetermined storage area is calculated, and the average value is treated as a singing score. In S114, the control part 11 determines the stability of the whole music played this time. Specifically, the stability is calculated by integrating and analyzing all the period stability for one song stored in a predetermined storage area. For example, as shown in the example of FIG. 3, the weights are set for the evaluation of “◯”, “Δ”, and “×” in the period stability, and the value obtained by weighted sum of the period stability of one song is stabilized. It can be considered as a degree.

  In S <b> 116, the control unit 11 transmits the singing history information regarding the music played this time to the management server 30. The singing history information includes the tune of the music played this time, the user ID of the user who reserved the music, the singing score calculated in S112, the stability determined in S114, and the current date. And are included.

  On the other hand, in S300, the management server 30 receives the singing history information from the karaoke apparatus 10. In S302, the management server 30 stores the singing history information received in S300 in association with the user ID included in the singing history information. The above-described processing for transmission and storage of singing history information is performed for each performance. Alternatively, the karaoke apparatus 10 temporarily stores the singing history information related to the singing performed by the user in the storage unit 13 or the like during the period from when the user who has an account logs in to when the user logs out, and then logs out. Sometimes, it may be transmitted to the management server 30 collectively. And the management server 30 preserve | saves the singing history information collectively transmitted to the user at the time of logout in the singing history database 31. FIG.

[Description of recommendation information display processing and history information provision processing]
The recommended information display process executed by the remote control terminal 20 and the history information providing process executed by the management server 30 will be described with reference to the flowchart of FIG. The recommended information display process is a process executed when an operation for requesting display of recommended information is performed when receiving a performance reservation for a song from a user at the remote control terminal 20. The history information transmission process is a process that is executed every time the management server 30 receives a singing history information acquisition request from the remote control terminal 20.

  In S400, the control unit 21 of the remote control terminal 20 determines whether or not a user who makes a music performance reservation is currently logged in. When the user is not logged in (S400: NO), the control unit 21 ends this process. On the other hand, when the user is logged in (S400: YES), the control unit 21 proceeds to S402. In S <b> 402, the control unit 21 acquires singing history information regarding the logged-in user determined in S <b> 400 (hereinafter referred to as the user) from the management server 30. Specifically, the control unit 21 transmits a singing history acquisition request with the user ID of the user to the management server 30 and receives singing history information transmitted from the management server 30 as a response thereto.

  On the other hand, in S <b> 500, the management server 30 receives a singing history acquisition request from the remote control terminal 20. In S502, the management server 30 reads the singing history information corresponding to the user ID included in the received singing history acquisition request from the singing history database 31, and transmits this to the requesting remote control terminal 20.

  In S404, the control part 21 acquires the information regarding the music which the said user sung last time from the karaoke apparatus 10. FIG. This information includes information indicating the singing score scored at the time of the last singing. In S406, the control unit 21 expands the list of singing history information acquired in S402 in the memory. In S408, the control unit 21 selects a display order for the singing history information developed in the memory. Specifically:

  First, in S410, the control unit 21 determines whether or not the performance reservation accepted at this time is the performance reservation for the first song after the user logs in. If it is the performance reservation for the first song by the user (S410: YES), the control unit 21 proceeds to S412. In S412, the control unit 21 displays recommendation information obtained by sorting the singing history information in the order of stability. Specifically, the control unit 21 sorts the list of singing history information expanded in the memory in descending order of stability, and gives each singing history information a priority of stability. At this time, it may be configured such that the date included in the singing history information is older than the certain period and excluded from the sorting target, and the singing history information is newer than that and is sorted. In addition, when there is a plurality of singing history information for the same piece of music, only the singing history information of the newer date may be subject to sorting, and the singing history information of the older one may be excluded. And the control part 21 displays the content of the singing log | history information ranked based on stability on the display part 24 as recommendation information of stability priority.

  On the other hand, if the performance reservation accepted at this time is a performance reservation for the second and subsequent songs by the user (S410: NO), the control unit 21 proceeds to S414. In S414, the control part 21 determines whether the singing score scored at the time of the user's last singing is less than a predetermined reference value. When the last singing score of the user exceeds the reference value (S414: NO), the control unit 21 proceeds to S412. In S412, the control unit 21 displays recommendation information obtained by sorting the singing history information in the order of stability.

  On the other hand, when the previous singing score of the user is below the reference value (S414: YES), the control unit 21 proceeds to S416. In S416, control part 21 displays recommendation information which sorted song history information in order of song score. Specifically, the control unit 21 sorts the list of singing history information developed in the memory in descending order of singing scores, and gives each singing history information a priority of singing score. At this time, it may be configured such that the date included in the singing history information is older than the certain period and excluded from the sorting target, and the singing history information is newer than that and is sorted. In addition, when there is a plurality of singing history information for the same piece of music, only the singing history information of the newer date may be subject to sorting, and the singing history information of the older one may be excluded. The control unit 21 displays the content of the singing history information ranked based on the singing score on the display unit 24 as singing score priority recommendation information.

  A specific example of the recommendation information displayed in S412 and S416 will be described with reference to FIG. The code | symbol (a) of FIG. 7 is an example of the screen by which the recommendation information of stability priority was displayed on the display part 24 by which the singing history information regarding the said user was sorted in order of high stability. Moreover, the code | symbol (b) of FIG. 7 is an example of the screen by which the recommendation information of the singing score priority displayed on the display part 24 by which the singing history information regarding the said user was sorted in order of a singing score high is displayed. In these recommended information images, information representing the rank, the name of the song, the date of singing, the singing score, and the stability is displayed for each piece of music. In addition, the recommendation information of the code | symbol (a) of FIG. 7 and (b) shall be produced from the same user's singing history information.

  As illustrated in FIG. 7, it can be seen that the recommendation order for the stability priority and the recommendation information for the singing score priority differ in the recommended order even for the same music. Therefore, for example, when a user selects a song to be sung first, the stability priority recommendation information is useful in a scene where importance is placed on the stability of the singing. On the other hand, singing score priority recommendation information is useful in scenes that focus on acquiring a high score with the singing scoring function rather than the singing stability.

  In particular, when a user selects a song to be sung first, the stability-first recommendation information is displayed, so that when a user visits a karaoke store and decides what song to sing first, It can be used as a clue to select music that can be stably sung so as not to deteriorate the atmosphere.

  Further, when the user makes a performance reservation for the second and subsequent songs, depending on the quality of the singing score related to the previous singing, it is possible to display the stability priority recommendation information or the singing score priority recommendation information. . By doing in this way, the music sung in the flexible aspect according to the result of the previous song can be recommended.
