  Hereinafter, embodiments of the present invention will be described. The communication karaoke system shown in FIG. 1 has a host device 1 and a karaoke device 2. Moreover, the user of karaoke owns the user terminal 3 (personal computer 3A, tablet terminal 3B, mobile phone 3C). The host device 1 and the karaoke device 2 and the host device 1 and the user terminal 3 are communicably connected by a transmission line 4.

  The host device 1 functions as a server and accumulates and manages various information such as customer information and history information. As illustrated in FIG. 2, the host device 1 includes a host-side control unit 11, a host-side communication unit 12, and a host-side storage unit 13.

  The host-side control unit 11 is a central part of control in the host device 1 and includes a CPU 11a and a memory 11b. The CPU 11a executes various controls according to the operation program stored in the memory 11b. The memory 11b is a storage element that stores a program to be executed by the CPU 11a and temporarily stores various types of information when the program is executed.

  The host-side communication unit 12 provides an interface for connecting the host device 1 to the transmission path 4. Thereby, various information can be transmitted / received between the host apparatus 1 and the karaoke apparatus 2 and between the host apparatus 1 and the user terminal 3. For example, the singing history and scoring results of karaoke songs, and messages indicating the user's desired game songs (competition desired songs, duet desired songs) and singing recommended songs (other user's desired game songs, which will be described later) Various types of information can be sent and received.

  The host-side storage unit 13 is a storage device that stores a large amount of information, and is configured by, for example, a hard disk drive. A partial area of the host-side storage unit 13 is used as a customer information storage area 13a.

  The customer information storage area 13a is an area for storing information about the user (customer), an attribute information storage area 13b for storing attribute information, a history information storage area 13c for storing history information, and a recommended song information. A recommended song information storage area 13d is provided. The host-side storage unit 13 corresponds to a singing history storage unit and a recommended song information storage unit.

  As the attribute information stored in the attribute information storage area 13b, for example, as shown in FIG. 3, user ID, address, telephone number, age, sex, and occupation are listed. Among these, the user ID is information for identifying the user, and is given to each user.

  In the history information storage area 13c, all singing histories sung by each user in the past are stored each time a song is performed. In the example shown in FIG. 4, a scoring result (score) and an evaluation value for each evaluation item that is the basis thereof are stored together with each information of the music ID and the singing date and time. Specifically, each evaluation value is stored for evaluation items consisting of pitch, stability, rhythm, expressive power (inflection, shackle, fist, fall), vibrato, long tone, and score. By developing these evaluation values in the radar chart of FIG. 5, in other words, by grasping the level of each evaluation value, the singing tendency of the user can be grasped. Moreover, as shown in FIG. 4, each evaluation value is sorted, for example, for each karaoke piece and in order of singing date and time, and a song average in units of each karaoke piece is stored. In addition, an overall average for all songs is also stored.

  Here, the evaluation item of a singing score is demonstrated. The pitch is the distance or pitch of the sound. Stability is the degree of pitch stability. Rhythm is to keep a certain tempo in time with the song. Expressive power is the ability to perform singing expressions, and is evaluated based on the details of intonation, sneezing, fisting, and fall.

  Intonation is a technique for singing with loudness. Scribbing is a technology that smoothly raises the pitch from a low pitch to the original pitch. Fist is a decorative melody that moves the sound finely in the basic melody. Fall is a technique for smoothly sliding down from the original pitch toward a lower pitch. Vibrato is to swing the pitch up and down. A long tone is the sound of the same pitch for a long time with a single breath.

  And the score shown in FIG. 4 is a scoring value obtained by comprehensively evaluating each item. For example, whenever a karaoke apparatus set in the scoring mode plays a karaoke piece, singing is performed and an overall score is calculated.

  As shown in FIG. 6, the recommended song information storage area 13d is configured to be able to store recommended song information for a plurality of songs for each user. In the recommended song information, a song ID indicating a recommended song is stored in a state associated with a user ID of a certain user. As will be described later, this recommended song is set on the condition that a karaoke game has been unsuccessful because no player is found even though a certain user desires karaoke game (match karaoke, duet singing). Is done.

  In addition, as conditions for losing karaoke games, for example, participation in karaoke games was recruited, but there were no users to recruit, and the use of similar singing tendency using the technology disclosed in Patent Document 4 However, there is no candidate who antagonizes the singing level and the karaoke game is not established. And the host side control part 11 (recommendation means) notifies a game desired music to other users as a song recommendation music on condition that the karaoke game which a certain user desires was not materialized.

  In the present embodiment, a message indicating the recommended content is transmitted to at least one of the karaoke device 2 used by another user or the user terminal 3 owned by the user. For example, if the notification partner uses the karaoke device 2, the message is displayed using the monitor 23 or the remote control device 26 (see FIG. 7) provided in the karaoke device 2 being used. Moreover, you may display the message of recommendation content on the my page assigned to each user. Further, if the notification partner registers the mail address of the user terminal 3, the mail may be transmitted to the registered mail address.

  Here, the notification partner of the recommended music can be selected by various methods. For example, it is possible to select a recommended song notification partner (other users) from a plurality of users based on the singing history.

  First, a notification partner can be selected based on the tendency to select a song. For example, another user who is singing a large number of music pieces of an artist who sings a game desired song can be selected as a notification partner. This is because a user who sings a lot of music of the same artist is likely to be able to sing the game desired music well.

  Moreover, a notification partner can be selected based on the past scoring results. For example, another user with a high overall average of scoring results can be selected as a notification partner. This is because a user who has a high scoring result for various music pieces is likely to sing the game desired music piece well.

  In addition, a notification partner can be selected by a singing technique (balance of evaluation values of each evaluation item). That is, the radar chart of all songs by a user has the shape shown by a solid line in FIG. 5, and the radar chart of all songs by another user has a shape shown by a dashed line in FIG. If so, it is determined that the singing technique is similar because the shape of the chart is very similar, and is selected as a notification partner.

  Note that whether or not the chart shapes are similar can be determined by obtaining a correlation. That is, based on the singing history, an evaluation value for each evaluation item is obtained for a plurality of users, and a user whose correlation coefficient for the evaluation value for each evaluation item for a certain user is equal to or higher than a criterion value is notified You can choose as

  Further, in this online karaoke system, if the proficiency level of the recommended song satisfies a predetermined recommended condition, that is, a judgment condition that can be regarded as a level that can compete with the proficiency level of a certain user, a flag indicating that the condition is cleared is set. Set (indicated by symbol O in FIG. 6). That is, the host-side control unit 11 (recommended means) recognizes other users' proficiency with respect to the recommended music from the scoring history of other users, and sets a flag when the recommended condition is satisfied.

  The proficiency level of the recommended song can be acquired based on the scoring result of the scoring game. For example, it can be acquired based on the average score of the total number of times for the recommended music or the average score of the latest several times. In this case, the ratio of the average score of another user to the average score of a certain user is acquired as the proficiency level. Further, when the proficiency level is a predetermined ratio or higher (for example, 95% or higher), it is determined that the recommended condition is satisfied.

  When it is determined that the above recommended conditions are satisfied, the host-side control unit 11 serving as a recommended means provides a karaoke game (matching karaoke, duet) to a certain user and other users with a desired game (recommended music). Singing) is recommended. In this embodiment, similarly to the notification of the recommended song, the notification is sent to the monitor 23 and the remote control device 26 provided in the karaoke device 2 being used, or an email is transmitted to the registered email address.

  In addition, the recommendation of karaoke game is performed on the condition that a certain user and another user are using the karaoke device 2, in other words, logged in as a user of the karaoke device 2. Is preferred. This is because the possibility of establishment of a karaoke game is enhanced by encouraging karaoke games during a period in which each user uses the karaoke device 2.

  The singing microphone 24 is connected to the karaoke main body 21, and converts a user's voice or the like into a microphone signal and inputs it to the karaoke main body 21. This microphone signal is appropriately adjusted by the karaoke main body 21 and mixed with the karaoke performance sound or the like. The video camera 25 shoots the karaoke room RM and generates a video signal. The video camera 25 is also connected to the karaoke main body 21, and the generated video signal is input to the karaoke main body 21.

  The remote control device 26 includes a short-range wireless communication unit capable of bidirectional communication for transmitting and receiving information to and from the karaoke main body 21 and is operated when a karaoke song is reserved. When reserving karaoke music, the remote control device 26 transmits an operation signal including a music ID for identifying the music to be played. And the karaoke main body 21 manages the karaoke music selected by the user in a queue.

  In addition, the remote control device 26 of the present embodiment includes a display unit (not shown) with a touch panel, and can be used during user authentication or as the user terminal 3. Moreover, it is used when determining the opponent of a battle karaoke or a battle song, or determining the opponent or a duet song of a communication duet. At that time, the remote control device 26 transmits operation information corresponding to the operation by the user to the host device 1 via the neighboring router device RT and the transmission path 4.

  Next, the karaoke main body 21 will be described in detail. As shown in FIG. 8, the karaoke main body 21 includes a main body side control unit 31, a main body side communication unit 32, a main body side storage unit 33, a sound source unit 34, an acoustic processing unit 35, a display processing unit 36, A video input unit 37 and an operation unit 38 are provided.

The CPU 31a executes various controls according to the operation program stored in the memory 31b. For example, an operation input process for receiving an operation from the operation unit 38 or a sequencer process that operates as a sequencer is performed. The memory 31b is a storage element that stores a program to be executed by the CPU 31a and temporarily stores various types of information when the program is executed.

  The main body side communication unit 32 provides an interface for connecting the karaoke main body 21 to the transmission path 4 via the router device RT. Therefore, the main body side communication unit 32 transmits and receives information to and from the router device RT. The operation of the main body side communication unit 32 is controlled by the main body side control unit 31.

  The main body storage unit 33 is a large-capacity storage device that stores various types of data, and includes a hard disk drive or the like. In the main body side storage unit 33, for example, a music data storage area 33a and a scoring program storage area 33b are provided.

  In the music data storage area 33a, music data for playing the karaoke music designated by the remote control device 26 is stored. The music data includes MIDI data, lyrics data, and reference data. MIDI data is automatic performance data (karaoke performance data) for automatically playing a sound source of an electronic musical instrument, and is composed of time-series note information. The note information is composed of various commands for controlling, for example, the timing of sound generation and mute, key pressing force, pitch, and playback pitch. The lyric data is character string data for displaying the lyrics telop in the karaoke music on the monitor 23. The reference data is used when scoring a karaoke song by a user, and is composed of time-series pitch information representing the pitch of a vocal.

  A scoring program is stored in the scoring program storage area 33b. This scoring program is read by the main body control unit 31 with the setting of the battle mode and scoring mode, and is executed as appropriate. A scoring process is performed by executing this scoring program.

  In the scoring process, the singing signal corresponding to the user's singing sound is compared with the reference data. For example, the pitch information of the singing signal at the same timing and the pitch information of the reference data are sequentially compared in time series, and pitch difference information is acquired. Based on this difference information, the quality of the pitch is evaluated. The rhythm (timing) is evaluated by detecting the time difference between the frequency change of the singing signal and the frequency change of the reference data, and the inflection is evaluated by comparing the maximum sound and the minimum sound for each sector.

  Moreover, stability is evaluated based on the frequency change of a song signal. In other words, whether the pitch is straight (constant) or prone to tremble is detected, and the stability is higher as the pitch is straighter. Based on the frequency of the singing signal, the presence / absence of squeak, fist, and fall is detected, and the periodicity is detected with respect to the frequency of the singing signal. Based on this periodicity, the presence / absence, length, and skill of vibrato are detected. Is determined. Further, the skill of the long tone is determined based on the stability of the singing pitch.

  The evaluation result of each item is temporarily stored in the work area of the memory 31b, and when the scoring process is completed, it is transmitted to the host device 1 together with the score (scoring result) and the like. Then, the host device 1 stores the received score and evaluation result in the host-side storage unit 13 (customer information storage area 13a) shown in FIG.

  Next, the sound source unit 34 will be described. The sound source unit 34 shown in FIG. 8 is a part that generates a karaoke performance sound signal based on MIDI data. When the main body side control unit 31 performs sequencer processing, the sound source unit 34 processes waveform data according to MIDI data and outputs the processed musical sound signal to the acoustic processing unit 35.

  The acoustic processing unit 35 is a part that performs processing of the karaoke performance sound signal and processing of the microphone signal generated by the singing microphone 24. For example, in performance control of karaoke music, the sound processing unit 35 performs analog conversion on the musical sound signal output from the sound source unit 34 to generate a karaoke performance sound signal. Further, when a microphone signal from the singing microphone 24 is input, a singing signal is generated by appropriately adjusting. This singing signal is mixed with the karaoke performance sound signal and output to the speaker 22 as a sound emission signal.

  The display processing unit 36 performs display control of a background video or the like during karaoke performance. At the time of karaoke performance, background video data is input to the display processing unit 36, and the background video data is decoded. Then, the display processing unit 36 combines the lyrics telop with the video signal of the background video generated by the decoding, and outputs the combined video signal to the monitor 23. At that time, the display processing unit 36 synthesizes the lyrics telop based on the lyrics data output by the sequencer processing in the main body side control unit 31. Also, the display color of the lyrics telop is changed according to the color change command output by the sequencer processing. As a result, the composite video in which the lyrics telop is superimposed on the background video is displayed on the monitor 23, and the display color of the lyrics telop is changed in accordance with the progress of the karaoke music.

  The video input unit 37 is a part that captures a video signal from the video camera 25, and is configured by, for example, an interface circuit. The input video signal is converted into image data for each frame and stored in the main body storage unit 33.

  The operation unit 38 includes a panel switch, a remote control receiving circuit, and the like, and outputs an operation signal corresponding to the operation of the panel switch and the remote control device 26 to the main body side control unit 31. The main body side control unit 31 detects an operation signal by performing an operation input process, and executes a corresponding process. Note that the panel switch and the remote control device 26 include various key switches (not shown) for selecting an operation.

  Next, an outline of operation by the communication karaoke system of the present embodiment will be described. This online karaoke system recommends singing to other users using a song desired by a user as a recommended song, and the proficiency level of the recommended song (game desired song) by another user is determined according to a predetermined recommended condition. In the case of exceeding the above, a feature is that a karaoke game with a desired song is recommended between a certain user and another user. For this reason, it demonstrates centering on the process at the time of recommending a karaoke game.

  Further, as described above, karaoke games include battle karaoke and duet singing, and here, description will be given using battle karaoke as an example. In addition, as shown in FIGS. 9 to 13, a communication karaoke system in which four karaoke apparatuses 2 </ b> A to 2 </ b> D are connected to one host apparatus 1 so as to communicate with each other will be described as an example.

  This process is started when a certain user requests execution of battle karaoke. In the example of FIG. 9, the user A of the karaoke apparatus 2A requests execution of the battle karaoke. The execution request is made, for example, when the user A operates the remote control device 26 provided in the karaoke apparatus 2A. When the request operation is performed, request information indicating that is transmitted from the karaoke apparatus 2 </ b> A to the host apparatus 1. This request information includes a user ID indicating the user A and a song ID of a karaoke song desired to be played.

  When the request information is received, the host device 1 publishes the recruitment content and solicits opponents (not shown). Here, if the opponent does not appear even after the specified time has elapsed, the host-side control unit 11 of the host device 1 functions as a recommendation unit. And a certain user's desired music for a battle is notified as a recommended song for singing by another user. At that time, the host-side control unit 11 selects a notification partner from a plurality of users. As mentioned above, users who have similar singing techniques (evaluation values for each evaluation item), and users who sing a lot of artists' songs that sing songs that they want to play as notification partners (other users) Selected.

  When the notification partner is determined, the host-side control unit 11 (recommendation means) recommends a recommended song indicating a song recommended for the notification target person (a song desired by a certain user) as illustrated in FIG. Is notified using the monitor 23 or the like. In the example shown in FIG. 10, two users B and D are selected from three users B to D as notification partners, and karaoke apparatuses 2B and 2D used by these users B and D, and The recommended song information is notified to the user terminals 3 owned by the users B and D. By confirming the notified recommended song information, the users B and D can be motivated to sing the recommended song.

  As shown in FIG. 11, when the users B and D who are notified of the recommended music perform a karaoke song in the scoring game, the main body side control unit 31 scores the song, and the scoring result and the music ID are associated with each other. The scoring information is transmitted from the karaoke device 2 to the host device 1. The host device 1 accumulates the received scoring information in the customer information storage area 13a of the host side storage unit 13. And the host side control part 11 functions as a recommendation means, and when the received scoring result is the scoring result of the user's recommended music, it recommends from scoring history (scoring information accumulated in the customer information storage area 13a). Recognize the proficiency level of the song. As described above, the proficiency level of the recommended song is acquired by the ratio of the average score of another user to the average score of a certain user. Then, the host side control unit 11 determines whether there is a user who satisfies the recommended condition.

  When a user who satisfies the recommended condition appears, the host-side control unit 11 (recommended means) can connect a user who satisfies the recommended condition (another user) and a user who wants to play the game (a certain user). The recommendation information recommending the execution of the battle karaoke is transmitted to each. This recommendation information includes information (for example, a user ID and a music ID) indicating each user and the battle song. The recommended information is sent immediately after other users meet the recommended conditions, or when other users are singing the recommended song, and the singing level has improved and it can be determined that the recommended conditions have been met, This can be done after the next day when other users meet the recommended conditions. And as above-mentioned, it is preferable to transmit on condition that each user is using the karaoke apparatus 2. FIG.

  In the example shown in FIG. 12, it is determined that among the two users B and D, the user B satisfies the recommended conditions. For this reason, the host-side control unit 11 owns the karaoke device 2A used by the user A who desires a match, the karaoke device 2B used by the user B who satisfies the recommended conditions, and the users A and B. The recommended information is transmitted to the user terminal 3. In the karaoke device 2A or the karaoke device 2B that has received the recommendation information, a message is displayed on the monitor 23 or the remote control device 26. A message is also displayed on the user terminal 3.

  Each user who confirms the recommended information answers whether or not to perform a karaoke game with the desired song (recommended song). For example, the remote control device 26 is operated to transmit information indicating acceptance or rejection of the game to the host device 1. Here, if each user consents, the karaoke game is executed. For example, as shown in FIG. 13, the song ID of the desired song is sent to the karaoke apparatuses 2A and 2B, and the battle karaoke is performed. Then, scoring result information is transmitted from each karaoke device 2A, 2B (main body side control unit 31) to the host device 1, and result information such as a battle result is sent from the host device 1 (host side control unit 11) to each karaoke device 2A. , 2B and displayed on the monitor 23. If at least one user refuses, the karaoke game is not executed, and information indicating that is transmitted to each karaoke apparatus 2A, 2B.

  Next, a flowchart for realizing the above-described operation relating to the karaoke game will be described with reference to FIGS. For convenience of explanation, here, it is a case where a battle karaoke is performed, and a user who desires a battle karaoke uses the first karaoke device 2 and another user uses the second karaoke device 2. An example will be described. That is, the 1st karaoke apparatus 2 respond | corresponds to 2A of karaoke apparatuses of FIGS. 9-13, and the 2nd karaoke apparatus 2 respond | corresponds to karaoke apparatuses 2B-2D similarly.

  As shown in FIG. 15, the user who wishes to play karaoke performs login processing (S11). In this example, the user operates the remote control device 26 included in the first karaoke device 2 to display a login intention. For example, the user touches a login button displayed on a display unit with a touch panel. By this operation, the login information is transmitted from the remote control device 26 to the host device 1. By receiving this login information, the host device 1 accepts login for the user (S31).

  After login operation, the 1st karaoke apparatus 2 judges the presence or absence of the recruitment request | requirement of the battle karaoke by a user (S12). As described above, this request operation is performed by an operation on the remote control device 26 provided in the first karaoke device 2. If there is a solicitation request from the user, the process proceeds to step S13, and if there is no solicitation request, the process proceeds to step S41 described later. In step S <b> 13, the first karaoke apparatus 2 transmits to the host apparatus 1 request information indicating that an opponent recruitment request has been made. This request information includes a user ID and a song ID. As a result, the host device 1 that has received the request information can recognize the karaoke piece that the user is requesting for the opponent and the player wants to play.

  The host device 1 is monitoring the request information (S32). When the request information is received, it is determined that a battle request has been made, and the process proceeds to step S34. On the other hand, during a period in which the request information is not received, the host device 1 determines that there is no battle request, and checks whether the recommended song information is registered for any user (S33). If no recommended tune information is registered for any user, the process proceeds to step S32 and monitoring of the request information is continued. On the other hand, if even one piece of recommended song information is registered, the process proceeds to step S64 described later.

  In step S34, the host device 1 publishes the offer details and solicits opponents. For example, the opponent is recruited by posting the recruitment content on a dedicated web page or by sending the recruitment information for notifying the recruitment content to the second karaoke apparatus 2. In the 2nd karaoke apparatus 2, it is judged whether the user who confirmed the offer content accepts a battle karaoke. And when accepting, a user operates remote control device 26 and performs operation which shows the will of acceptance. As a result of this operation, acceptance information indicating the intention of acceptance is transmitted from the second karaoke device 2 to the host device 1 (S22). In addition, when not accepting a battle karaoke, the user of the 2nd karaoke apparatus 2 does not operate anything. In this case, the 2nd karaoke apparatus 2 transfers to the process of step S23 mentioned later.

  The host device 1 monitors acceptance information from the second karaoke device 2 (S35). When the acceptance information is received, the host device 1 determines that there is an acceptor, and transmits establishment information indicating that a match karaoke game partner is found to each of the first karaoke device 2 and the second karaoke device 2 (S36). ), The process proceeds to step S38. On the other hand, if the opponent does not appear even after the lapse of the specified time, the host device 1 determines that there is no acceptor, and sends unsuccessful information indicating that the opponent for the battle karaoke does not appear to the first karaoke device 2. (S37), and the process proceeds to step S61 to be described later.

  First, a process when a game partner of the battle karaoke is found will be described. Each of the first karaoke device 2 and the second karaoke device 2 monitors establishment information from the host device 1 (S14, S23). And it determines with the game of battle karaoke having been established with reception of establishment information. Thereby, battle karaoke is performed between the 1st karaoke apparatus 2 and the 2nd karaoke apparatus 2 (S15, S24).

  When the battle karaoke is completed, the first karaoke apparatus 2 proceeds to step S12, and determines whether or not there is a request for recruitment of the battle karaoke by the user. Moreover, the 2nd karaoke apparatus 2 transfers to step S21, and judges the presence or absence of the recruitment request | requirement of the battle karaoke by a user.

  On the other hand, when transmitting the establishment information in step S36, the host device 1 confirms the presence or absence of recommended song information related to the user of the first karaoke device 2 (the requesting user who requested the battle karaoke) (S38). That is, the customer information of another user is searched, and the presence or absence of the recommended song information associated with the user ID of the requesting user is confirmed. If there is recommended song information, the recommended song information is deleted (S39). As a result, all the songs requested by the requesting user are deleted from the recommended songs of other users. If the recommended song information is deleted or if it is determined in step S38 that there is no recommended song information, the host device 1 moves to step S32 and monitors the request information.

  Next, a process in the case where a game opponent for battle karaoke is not found will be described. In this case, as shown in FIG. 16, the host apparatus 1 sets a recommended song (S61). That is, the host device 1 sets a battle tune in the battle karaoke that has not been established as a recommended song. Next, the host device 1 selects a recommended music notification partner (S62). As described above, a user who has a similar singing technique is selected as a notification partner. Next, recommended tune information is transmitted to the selected user (other users) (S63). Thus, when another user uses the second karaoke device 2, a message indicating the recommended song is displayed on the monitor 23 or the remote control device 26. Further, when another user accesses the My Page by operating the remote control device 26 or the user terminal 3, a message indicating a recommended song is displayed.

  When prompted by a message and another user sings the recommended song (S51), the grading result of the singing and the grading information indicating the singing song are transmitted from the second karaoke device 2 to the host device 1 (S52). ). Regardless of whether or not it is a recommended song, the scoring information is transmitted to the host device 1, but for the convenience of explanation, the scoring information about the recommended song is targeted.

  The host device 1 monitors the scoring information from the second karaoke device 2 (S64), and when the scoring information is received, the scoring information is accumulated in the customer information storage area 13a. The host-side control unit 11 recognizes the proficiency level of the recommended song for other users from the scoring history accumulated in the customer information storage area 13a (S65). Subsequently, the host-side control unit 11 determines whether or not the proficiency level of the recommended song satisfies the recommended condition (S66).

  Here, when the recommendation condition is satisfied, the host device 1 transmits the recommendation information to each of the first karaoke device 2 and the second karaoke device 2 (S67). Each karaoke device 2 monitors recommended information (S41, S53), and with the reception of the recommended information, a certain user (competitor requester) and other users (users who satisfy the recommended condition) Recognize that competitive karaoke is recommended. That is, a message indicating the recommended content is displayed on the monitor 23 or the remote control device 26. A message is also displayed on the user terminal 3. On the other hand, if it is determined in step S66 that the recommended condition is not satisfied, and if scoring information has not been received in step S64, the host device 1 proceeds to step S32 and monitors whether request information has been received. .

  Each user to whom the battle karaoke is recommended returns whether to accept or reject the battle karaoke (S42 to S44, S54 to S56). For example, each user indicates his / her intention by an action such as selecting and touching either the accept button or the reject button displayed on the display unit of the remote control device 26.

  When the user indicates an acceptance intention, for example, when the acceptance button of the remote control device 26 is touched, the karaoke device 2 transmits acceptance information indicating the acceptance to the host device 1 (S43, S55). . On the other hand, when the user indicates the intention of refusal, for example, when the refusal button of the remote control device 26 is touched, the karaoke device 2 transmits refusal information indicating the refusal to the host device 1 (S44, S56).

  These acceptance information or rejection information is received by the host device 1. Then, as shown in FIG. 17, the host device 1 determines whether both users have accepted or at least one user has refused (S91). Here, when both users accept, it is determined that the battle karaoke has been established, and establishment information indicating that fact is transmitted to each karaoke apparatus 2 (S92). On the other hand, when at least one user refuses, it is determined that the battle karaoke is not established, and the failure information indicating that is transmitted to each karaoke device 2 (S93).

  Each karaoke device 2 determines whether or not a battle karaoke has been established based on the establishment information or the failure information transmitted from the host device 1 (S71, S81). Here, when the failure information is received, the first karaoke device 2 notifies the user of the failure by the monitor 23 or the like, and proceeds to step S41. Similarly, the second karaoke apparatus 2 also informs the user of the failure by the monitor 23 or the like, and proceeds to step S51.

  On the other hand, when the establishment information is received, each karaoke device 2 executes the battle mode and performs karaoke singing (S72, S82), and the scoring result is transmitted to the host device 1 together with the user ID and the song ID. When receiving information such as a scoring result for each user, the host device 1 stores the received information in the host-side storage unit 13, and the host-side control unit 11 determines the result for the battle karaoke based on this information. The determination result is transmitted to each karaoke device 2 (not shown), and is displayed on the monitor 23 or the like to notify each user.

  As is apparent from the above description, in the communication karaoke system of the present embodiment, the karaoke game desired by a certain user has not been established (N in S35), and the game desired song is a recommended song for singing. To other users (S61 to S63). Then, if the proficiency level is recognized from the scoring history of other users of the recommended song (S65) and the recommended condition (judgment condition for the proficiency level of a certain user) is satisfied (Y in S66), a certain user A karaoke game with a desired song is recommended to other users (S67). For this reason, the possibility that a singer who antagonizes the singing level will appear in the future for a certain user's desired game tune increases, and it is possible to easily establish a battle karaoke. And about other users, improvement of motivation can be aimed at with the improvement of own singing level.

  Moreover, in this communication karaoke system, the host side control part 11 (recommendation means) has extracted the notification other party from several users based on a song history (S62). Thereby, the singing history will be taken into account when selecting other users, and the selection probability of the opponent who can compete with each other can be increased.

  Furthermore, the host-side control unit 11 (recommendation means) acquires evaluation values for each evaluation item for a plurality of users, and uses a correlation coefficient for an evaluation value for each evaluation item for a certain user that is greater than or equal to a criterion value. Since the user is extracted as the other user, a user having a similar singing technique can be selected as the other user.

  In addition, the host-side control unit 11 (recommendation means) transmits a message indicating the recommended content to at least one of the karaoke device 2 used by another user or the user terminal 3 owned by another user. Therefore, it is possible to reliably notify the recommended content to other users.

  Further, the host-side control unit 11 (recommended means) uses the karaoke device 2 used by each user on the condition that a certain user and another user use the karaoke device 2. Alternatively, since the message indicating the recommended content is transmitted to at least one of the user terminals 3 owned by each user, the execution probability of the karaoke game can be increased.

  The above description of the embodiment is for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof. For example, you may comprise as follows.

  In the above-described embodiment, the case where users who perform karaoke games use different karaoke rooms RM has been described. However, these users may use the same karaoke room RM.

  In addition, regarding the host-side control unit 11 (recommended means), the recommended conditions are not limited to the example shown in the embodiment (total score of a certain user × ratio). It may be determined to antagonize the proficiency level of a certain user.
