Description

  The present invention relates to a karaoke system for performing battle karaoke, and particularly relates to a karaoke system characterized by scoring in consideration of handicap.

  In a general scoring game in a karaoke system, a national ranking or the like is competed based on a score (scoring value) calculated when singing karaoke music. Currently, a plan such as a battle-type winning battle in which a plurality of users compete for scores is being broadcast on televisions and the like, and it is gaining popularity. The fun of this kind of competitive karaoke is that the users whose scores are competing with each other compete. Because it is difficult to find an opponent of the same level, it was difficult to enjoy the scoring game by avoiding the opponent or avoiding the fighting by themselves.

  In response to this problem, Patent Document 1 proposes a karaoke system configured to notify each user of the singing level of each user. Patent Document 2 proposes a karaoke system configured to combine opponents based on performance records such as performance frequency and performance evaluation (scoring value). Further, Patent Document 3 proposes a karaoke apparatus that calculates an increased scoring value based on a command input during a karaoke performance so as not to be noticed by a singer.

  However, in the karaoke system of Patent Document 1, the singing level of the opponent user is only displayed on the display unit of the karaoke device during the performance period of the battle song. For this reason, users with different singing levels may battle each other. In this case, the user's singing level will be known during the performance period, and the fun will be lost after starting to sing. Once you start singing, it is impolite to stop singing on the way, so you have to keep singing even if the fun is impaired.

  Moreover, in the karaoke system of patent document 2, the singing level is not considered in the combination. That is, even in this karaoke system, users with different singing levels may play against each other. In addition, although the user below a predetermined rank is also excluded from a combination object, this is performed for the purpose of adjusting the number of people. Therefore, this karaoke system has the same problem as the karaoke system of Patent Document 1.

  In addition, by using the technique of the karaoke device of Patent Document 3, that is, an increase in scoring value based on commands, it is possible to antagonize each user's score in battle karaoke. However, with this technique, the scoring value is increased without any grounds, so that the user who wants to enjoy the fighting karaoke will be less interested.

  This invention is made | formed in view of such a situation, The objective is to enable it to enjoy the fun of competitive karaoke even if it is users with a difference in a singing level.

  In order to achieve the above-mentioned object, the present invention evaluates a karaoke song by a certain user and a karaoke song by another user by dividing them into basic items and additional items, and evaluating the basic items and the above A karaoke system for competing for superiority and inferiority based on a scoring result obtained by combining evaluations with score items, and storing a singing history of a user who performed karaoke singing in association with identification information of the user Based on the singing history storage means and the singing history of each user who is the opponent, the proficiency level acquisition means for acquiring the proficiency level of each user about the battle song, and the proficiency level is high based on the acquired proficiency level A handicap giving means for giving a handicap to a user, and an adjusting hand for adjusting the evaluation of the additional items of at least one user who becomes an opponent based on the given handicap Characterized in that it has and.

  According to the present invention, the proficiency level of each user related to the battle song is acquired based on the stored singing history, and a handicap is given to the user who has a high proficiency level. And, since the evaluation of the added items is adjusted based on the handicap that is given, even users with different singing levels can antagonize the scoring results and enjoy the fun of competitive karaoke be able to. In addition, since the added item is also used for adjustment by handicap, an adjustment function based on the handicap can be easily incorporated.

  In the above karaoke system, the proficiency level acquisition means refers to the past number of singing of the battle song stored in the singing history storage means for each of the certain user and the other user, It is preferable to acquire the number of sings performed as the proficiency level of each user. In this configuration, since the proficiency level of the battle song is acquired based on the number of times the battle song has been sung in the past, the proficiency level can be easily acquired.

  In the karaoke system described above, the adjustment means sets the evaluation condition of the additional item for a user with low proficiency more advantageously than the evaluation condition for the additional item for a user with high proficiency. Is preferably adjusted. In this configuration, the scoring result of the user with low proficiency approaches the scoring result of the user with high proficiency, so that the fun of the battle karaoke can be further enhanced.

  In the above karaoke system, it is preferable that the additional item is composed of a plurality of details, and the adjusting means individually sets evaluation conditions for the plurality of details. With this configuration, fine adjustments can be made.

  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. And these are connected via the transmission line 3 so that communication is possible.

  The host device 1 functions as a server and accumulates and manages various information such as customer 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 3.

  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 and a handicap determination information storage area 13b.

  The customer information storage area 13a is an area in which user (customer) attribute information and history information are stored. For this reason, the host-side storage unit 13 corresponds to a singing history storage unit.

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

  As history information, for example, as shown in FIG. 4, all singing histories sung in the past by each user are stored each time singing is performed. In the illustrated example, a scoring result and a plurality of pieces of information that are the basis of the scoring result are stored together with information on the song ID and the singing date. Specifically, information on pitch, stability, rhythm, expressive power, vibrato / long tone, and score is stored. In the example shown in the drawing, each piece of information is sorted, for example, for each karaoke piece and in order of singing date and time, and a song average for 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. As shown in FIG. 5, basic items and added points are defined as evaluation items for singing scoring. Note that the evaluation values of the basic item and the added item are also stored each time a song is performed as information constituting a part of the history information in FIG.

  Basic items are items for evaluating the accuracy of singing, and include pitch, stability, and rhythm details. This basic item starts from a perfect score and is deducted every time a singing pitch outside the allowable range is detected. As for the stability and rhythm, points are greatly reduced as the degree of deviation from the allowable range increases. The added item is an item for evaluating the expression of the singing, and includes details of the singing technique such as expressive power, vibrato, and long tone. This added item is subject to evaluation on the number of times and skill, and the higher the number of detections and the higher the skill evaluation, the higher points are added.

  The pitch that constitutes the basic item is the distance or pitch of the sound, and is evaluated with an evaluation value of 0 to 100%. Stability refers to the degree of stability of the pitch, and is evaluated with an evaluation value of 0 to 100% as with the pitch. Rhythm is to maintain a constant tempo according to the music, and is evaluated in 7 stages.

  The expressive power that constitutes the added item is the ability to perform singing expression, and is evaluated based on the details of intonation, fisting, fist, and fall. Intonation is a technique of singing with the loudness of the voice, and is evaluated in 11 stages. Scribbing is a technique that smoothly raises the pitch from a low pitch to the original pitch, and is evaluated by the number of times. Fist is a decorative melody that moves the sound finely in the basic melody and is evaluated by the number of times. Fall is a technique for smoothly sliding down from the original pitch toward a lower pitch, and is evaluated by the number of times.

  Vibrato is to swing the pitch up and down, and is evaluated by the total number of seconds and skill (11 levels). The long tone is that a sound of the same height is emitted for a long time with one breath, and the skill is evaluated in 11 stages.

  And the score shown in FIG. 4 is a scoring result obtained by integrating the evaluation of the basic items and the evaluation of the added items. In this embodiment, every time the karaoke apparatus 2 set in the scoring mode performs a karaoke song, the evaluation based on the basic item (basic score) is adjusted by the evaluation based on the additional item (addition value). Singing (score calculation) is performed.

  Next, the handicap determination information storage area 13b shown in FIG. 2 will be described. In this area 13b, handicap determination information is stored. Here, the handicap determination information is for determining a handicap imposed on a user with a high singing level when users who are open to the singing level (singing proficiency level) perform a battle karaoke. This is information in which the level difference and the content of the handicap are combined.

  In this embodiment, the host-side control unit 11 is based on the singing history of each user who is an opponent, and is a proficiency level acquisition unit that acquires the proficiency level of each user for the battle song, and is used with a high proficiency level It functions as a handicap giving means for giving a handicap to a person. That is, when the host-side control unit 11 functions as a proficiency level acquisition unit, the host side control unit 11 indirectly recognizes the proficiency level of the battle song for each user based on the past number of singings related to the battle song.

  When the host-side control unit 11 functions as a handicap providing means, the host-side control unit 11 selects the item with the low evaluation value from the added items for the user with a low level of proficiency, and has an advantageous evaluation regarding the selected item. The evaluation conditions are set so that In the case of a user who has never sung a battle song in the past, the host-side control unit 11 refers to the singing history of other karaoke songs and obtains an advantageous evaluation regarding the item with the lowest evaluation. . In addition, when selecting a sub-item with a low evaluation value from the added items, it is desirable to convert each added item to the same evaluation axis for comparison.

  For this reason, the handicap determination information corresponds to information for setting the evaluation condition of the added item for the user with low proficiency more advantageously than the evaluation condition of the added item for the user with high proficiency. Specifically, it is composed of a combination of the difference in the number of singing times and the condition for increasing the evaluation value for the added item.

  For example, regarding the difference in the number of singings, level information such as 0 to 4, 5 to 10, 11 to 20, 21 times or more is used. Regarding the evaluation value increase condition, for each item of intonation, vibrato, and long tone, an increase amount of the evaluation value such as 0, +1, +2, +3,... Is used. On the other hand, for each item of fist, fist, and fall, a handicap coefficient (HC coefficient) that is multiplied by the number of appearances of each added item such as 1.0, 1.2, 1.4, 1.6... Is used. . It should be noted that such a combination of level information and an increase amount, and a combination of level information and an HC coefficient are set for each detail of the added item.

  Next, the handicap information transmitted from the host device 1 to the karaoke device 2 based on the handicap determination information will be described with a specific example. As the item of sneezing in the handicap determination information, the coefficient 1.0 is set for the singing frequency difference 0 to 4 times, the coefficient 1.2 is set for the frequency difference 5 to 10 times, and the frequency difference 11 to 20 times. It is assumed that the coefficient 1.4 is set so that the coefficient 1.4 is 21 times or more. And about a battle | competition song, suppose that the past singing frequency of one user was 10 times, and the past singing frequency of the other user was 3 times. Further, it is assumed that the other user has the lowest scoring evaluation value among the added items from the past singing history.

  In this case, the host-side control unit 11 (skill level acquisition means) acquires 10 times that is the number of singing of one user and 3 times that is the number of singing of the other user in the past. It is acquired from the customer information storage area 13a of the host side storage unit 13 (singing history storage means) as the degree. And the host side control part 11 (handicap provision means) determines with the other user's skill level being low based on the frequency | count of singing of each user.

  Next, the host-side control unit 11 refers to the handicap determination information stored in the handicap determination information storage area 13b, and generates handicap information based on the proficiency level of each user. That is, since the difference in the number of singing is 7 times and the number of times of squeezing is the smallest, the host-side control unit 11 sets the item to be added to screaming, sets its coefficient to 1.2, and sets other items ( Handicap information is generated by setting the coefficient of inflection, fist, fall, etc.) to 1.0, and increasing information such as vibrato is set to 0. In addition, the host-side control unit 11 determines a handicap value (numerical value, rank, HC value) according to the level of the frequency difference, and includes it in the handicap information.

  The handicap information generated in this way is transmitted to the karaoke main body 21 used by the user in a state in which the handicap information is associated with the user ID of another user with low proficiency. And in the karaoke main body 21, the received handicap information (HC value, HC coefficient) is memorize | stored in the handicap information storage area | region shown in FIG.7 (b). The stored handicap information is referred to when performing battle karaoke (described later).

  Next, the karaoke apparatus 2 will be described. As shown in FIG. 1, the karaoke apparatus 2 is installed in each karaoke room RM of the karaoke shop KB. And as shown in FIG. 6, it has the karaoke main body 21, the speaker 22, the monitor 23, the microphone 24, the video camera 25, and the remote control device 26.

  The karaoke main body 21 is a part that performs various controls related to karaoke, such as performance control of selected karaoke music, display control of lyrics and background video, and processing of analog signals input through the microphone 24. The karaoke main body 21 will be described in detail later. The speaker 22 is connected to the karaoke main body 21 and emits sound based on an analog signal from the karaoke main body 21. The monitor 23 is also connected to the karaoke main body 21 and displays video on the screen based on the video signal from the karaoke main body 21. Note that scoring results and handicap notifications are also made via the monitor 23.

  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 is used when authenticating a user, or used when determining an opponent or a song for a battle karaoke. At this time, operation information corresponding to the operation by the room user is transmitted to the host device 1. In this case, an operation signal is transmitted to the host device 1 via the neighboring router device RT and the transmission path 3.

  Next, the karaoke main body 21 will be described in detail. As shown in FIG. 7A, 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, and a display processing unit. 36, a video input unit 37, and an operation unit 38. These units are connected to a communicable state via the bus BS.

  The main body side control unit 31 is a central part of control in the karaoke main body 21, and includes a CPU 31a and a memory 31b. 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.

  As shown in FIG. 7B, a partial area of the memory 31b is used as a handicap information storage area. Here, the handicap information is information indicating a handicap imposed on a highly skilled user. As described above, the handicap information is determined by the host device 1 based on the handicap determination information and is received through the transmission path 3. Is done. And in this embodiment, the handicap is imposed on the user with high proficiency by advantageously setting the evaluation condition of the added item of the user with low proficiency. For this reason, handicap information is memorize | stored in the state matched with the user ID of the user with low proficiency.

  The main body side communication unit 32 provides an interface for connecting the karaoke main body 21 to the transmission path 3 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 the scoring program.

  In this 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 shown in FIG. 7B, 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). Note that the scores and the like that are transmitted and stored include those that do not take handicap information into account. This is because the user is properly evaluated in the next battle karaoke. Therefore, the karaoke apparatus 2 (the karaoke main body 21) performs scoring in consideration of handicap information and scoring without consideration.

  Next, the sound source unit 34 will be described. The sound source unit 34 shown in FIG. 7A 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.

  In addition, the display processing unit 36 displays the handicap value (HC value) imposed on the user based on the handicap information on the monitor 23 at the time of execution of the battle karaoke, and displays the scoring result and win / loss of the user. It is displayed on the monitor 23 together with a nickname or the like. The HC value is an index representing the difference in proficiency between users, and for example, a numerical value such as 0 to 20 or a character such as ABC is used. In addition, the HC value may be a large load imposed on a user with a high level of proficiency, or a large increase in evaluation for a user with a low proficiency level.

  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, the outline of the operation by the karaoke system of the present embodiment will be described. In addition, since this karaoke system has the characteristics in the content of battle karaoke, operation | movement is demonstrated centering on battle karaoke. In the following description, a case where two users who use the same karaoke room RM perform a battle karaoke will be described as an example.

  After each user logs in by operating the remote control device 26, the battle karaoke mode is set and the battle tune is determined. Then, the host side control unit 11 (skill level acquisition means) shown in FIG. The customer information storage area 13a of the singing history storage means) is accessed, and the number of times each user sings the battle song is acquired as a proficiency level.

  Next, the host side control part 11 (handicap provision means) provides a handicap to a user with many singing times based on the acquired singing number (skill level). In the present embodiment, the handicap is given by setting the evaluation condition of the added item for the user with a small number of singing so as to be more advantageous than the evaluation condition of the added item for the user with a large number of singing.

  The handicap is given based on the handicap determination information stored in the host-side storage unit 13 (handicap determination information storage area 13b). Suppose that the evaluation item of the vibrato in the battle song has a lower evaluation than the other evaluation items for the user who sings less. In this case, the host-side control unit 11 refers to the host-side storage unit 13 and acquires the level from the difference in the number of singings, and acquires an increase amount of the evaluation value corresponding to the acquired level. In addition, the HC value corresponding to the acquired level is also acquired.

  The host device 1 (the host-side control unit 11 and the host-side communication unit 12) uses the increase amount of the evaluation value and the HC value as the handicap information, and associates it with the user ID of the user who sings less frequently. 21 to send. Further, the karaoke main body 21 stores the received handicap information in the main body side storage unit 33 (handicap information storage area). This completes the handicap application.

  When the order of the battle karaoke arrives, as shown in FIG. 8A, the monitor 23 (handicap display means) displays the title of the battle song in the battle song display area 23a and the HC value in the handicap display area 23b. Is displayed. Thereby, the size of the handicap can be notified to each user.

  In addition, when announcing the size of the handicap, it may be notified as to which added item is advantageously set. If the evaluation item for vibrato is advantageously set, a wording such as “This time has been set advantageously for vibrato!” May be displayed in the handicap display area 23b.

  Next, as shown in FIGS. 8B and 8C, each user sings a battle song. Here, in this embodiment, a user with a low level of proficiency (a user who enjoys the benefits of a handicap) is sung first, and then a user with a high level of proficiency (a user with a handicap imposed) is sung. Singing. Moreover, the scoring result of the singer with low proficiency, that is, the scoring result of the singing in consideration of the handicap is notified before the singing of the singer with high proficiency.

  Then, as shown in FIG. 8D, when the singing by a highly skilled singer is finished, the score (evaluation result) of each user is displayed side by side in the result display area 23c of the monitor 23. By comprising in this way, even if it is a user with a difference in the proficiency level of a battle | competition music, the score of a battle karaoke can be antagonized and fun can be enjoyed. In addition, since the scoring results of singer with low proficiency level (scoring result considering handicap) are informed before the singing of high proficiency users, the motivation of users with high proficiency level is increased. You can also. In addition, when a singer who has a low level of proficiency scores, items with low evaluation on the history are likely to be scored, so the handicap effect is likely to appear, and the score is likely to antagonize.

  Hereinafter, with reference to FIG. 9, the flowchart for implement | achieving the above-mentioned operation | movement regarding battle karaoke is demonstrated.

  First, the user (singer) of the karaoke room RM performs a login process (S11). In this login process, authentication information such as a user ID and a password is input by an operation on the remote control device 26. This authentication information is transmitted to the host device 1. Then, the host device 1 performs user authentication based on the received authentication information (S31), and transmits the authentication result to the karaoke device 2 (the karaoke main body 21).

  Next, the user operates the remote control device 26 to set the mode of the karaoke device 2 to the battle karaoke mode (S12). By this operation, mode setting information is transmitted to the host device 1. Then, the host device 1 recognizes that the target karaoke device 2 is set to the battle karaoke mode based on the mode setting information (S32).

  Next, the user operates the remote control device 26 to determine the user who performs the battle karaoke and the battle song (S13). By this operation, the song ID of the battle song is transmitted to the host device 1 together with the user ID of each user. Then, the host device 1 recognizes the battle song and each user based on the song ID and the user ID (S33), and acquires the proficiency level (past number of singings) of each user for the battle song (S34). ).

  If the proficiency level is acquired, the host device 1 determines the handicap according to the procedure described above, and transmits the handicap information (HC value, increase amount of the evaluation value) to the karaoke device 2 in association with the user ID ( S35). And in the karaoke apparatus 2, the received handicap information is memorize | stored in the memory 31b of the main body side control part 31 (S14).

  When performing a battle karaoke, the karaoke apparatus 2 displays a handicap based on the handicap information (HC value) on the monitor 23 and notifies each user (S15). Then, the singing by the 1st user (user with low proficiency) without a handicap is performed (S16), and the singing by the singer is scored and notified (S17). Here, singing is scored taking into account handicap information (an increase in evaluation value), and the raised score is reported.

  Then, the scoring result is transmitted to the host device 1 together with the user ID, and stored in the host-side storage unit 13 (customer information storage area 13a) (S36).
