Description

  The present invention relates to a karaoke scoring method and a karaoke scoring system system for scoring the skill of a user's singing.

Conventionally, a karaoke scoring system having a scoring function for scoring skill of karaoke singing has been put into practical use. Also, a karaoke scoring system is known that has a ranking function that ranks the scores of the scoring results based on data obtained by scoring the scoring results and notifies the user of the ranking (for example, see Patent Document 1). In this kind of karaoke scoring system, in order to increase the interest of the ranking function by increasing the number of samples of scoring results, the scoring results of all the songs that were scored are scaled by store, local or national scale. The total rank is calculated in a lump, and the overall ranking for the scoring results of all the music is calculated.

  However, karaoke music includes music that is difficult to sing well and simple music, and the difficulty of singing varies from music to music. For example, the graph shown in FIG. 14 shows the score of the scoring result when a plurality of users with different skill levels (singing ability) sing songs A and B having different difficulty levels, and the user's singing ability on the horizontal axis. The score of the scoring result is shown on the vertical axis. As shown in this graph, it can be seen that the music A that tends to be distributed with a high score as a result of scoring is a simple music with a low difficulty of singing. On the other hand, it can be seen that the music B that tends to be distributed in a low score as a result of scoring is a difficult music with a high degree of difficulty in singing. Here, the score when Mr. X whose singing ability is higher than the average level sings difficult song B is compared with the score when Mr. Y whose singing ability is lower than the average level sings simple song A As a result, the score of Mr. X who should have high singing ability is lower than the score of Mr. Y who has low singing ability. In this case, it is shown that the score of the scoring result does not necessarily evaluate the user's singing ability.

  In this way, if you sing a simple song, it is easy to get a high score, and if you sing a difficult song, it tends to be difficult to get a high score, so even if you simply compare the scoring scores of songs with different difficulty levels, The user's singing ability cannot be evaluated fairly. In addition, as described above, even in the case of assigning a comprehensive ranking based on the summation of the scoring results of all the music, the average value and standard deviation of the scoring results for each music vary depending on the difficulty of the music, Simply comparing the scores of the scoring results does not give a ranking that fairly evaluates the user's singing ability.

  Also, if it seems that the score and ranking of the score result will be affected by the difficulty level of the sung song, for example, when participating in a karaoke event where prizes according to the scoring ranking are offered, etc. There is a risk that it may be necessary to sing only simple music even if you don't like it because you want to win and be ranked higher. In such a situation, it may be possible to lose the original pleasure of karaoke such as enjoying and singing your favorite music.

  This invention is made in order to solve the above problems, and it aims at providing the karaoke scoring method and karaoke scoring system which can perform fair scoring in consideration of the difficulty of the singing for every music. To do.

The karaoke scoring method according to claim 1, which is made to achieve the above object, includes a scoring procedure, a storing procedure, a correction score calculating procedure, a presentation procedure, a scoring history storing procedure, a receiving procedure, and a correction score. It has a recalculation procedure and a history presentation procedure . In the scoring procedure, the user's singing input during the performance of karaoke music is scored. In the accumulation procedure, the actual number of scoring results calculated in the scoring procedure is statistically accumulated in the scoring result database in association with each piece of music. In the correction score calculation procedure, when the scoring result for a song of a certain song is calculated in the scoring procedure, the average value and standard deviation of the set of real scores corresponding to all the songs by the data accumulated in the scoring result database, and Based on the average value and standard deviation of the set of real scores corresponding to the music related to the scoring results, and the deviation value of the real score of the scoring results based on the set of real scores corresponding to the music related to the scoring results Then, the correction score is calculated such that the deviation value of the correction score with the set of real scores corresponding to all music as the population is equal. In the presentation procedure, the correction score calculated in the correction score calculation procedure is presented to the user as the final result of scoring the song.

  Comparing the statistical values for the set of real scores of all songs on which the singing was scored with the statistical values for the set of real scores corresponding to a specific song, The difficulty can be estimated. Therefore, in the present invention, using the average value and the standard deviation of the set of real scores, the deviation value of the real score of the scoring result using the set of real scores corresponding to the music related to the scoring result as a population, and all songs The correction score is calculated such that the deviation value of the correction score with the set of real scores corresponding to is equal to the population. By doing in this way, the skill of a user's song can be scored correctly and fairly in the aspect which considered the statistical feature of the real score which arises with the difficulty for every music. In addition, it is preferable that the user can accurately grasp his / her singing ability by presenting the score corrected by such a method to the user.

  Moreover, the correction score scored by the karaoke scoring method of the present invention can be totaled, and this totaled data can be used for ranking the scoring results. By doing in this way, even when the scoring results for a plurality of songs with different difficulty levels are tabulated in a lump, ranking can be performed based on a fair score obtained by correcting the score difference due to the difference in the difficulty level of the songs. Therefore, it is possible to calculate a ranking that accurately and fairly reflects the user's singing ability.

Further, in the karaoke scoring method according to claim 1, in the scoring history accumulation procedure, the actual score of the scoring result calculated in the scoring procedure and the correction at the time of singing calculated in the correction score calculating procedure for the actual score The score is stored in the personal scoring history database as the scoring history corresponding to the identification information of the user who performed the singing in association with the identification information of the music corresponding to these scores. In the acceptance procedure, a scoring history browsing request corresponding to the user is accepted.

  Then, in the correction score recalculation procedure, in response to the browsing request received in the reception procedure, the actual score score corresponding to the user stored in the personal score history database and the music identification information corresponding to the actual score Based on the above, a correction score for the actual score is newly calculated based on the data accumulated in the current scoring result database. In the history presentation procedure, the correction score newly calculated in the correction score recalculation procedure and the past correction score calculated at the time of singing the music stored in the personal scoring history database are presented to the user. .

  According to the karaoke scoring method configured as described above, the personal scoring history stored in the personal scoring history database can be browsed in response to a viewing request from the user. Furthermore, in this browsing, it is possible to compare the past correction score calculated when the user sang with the correction score obtained by newly correcting the actual score at the time of singing according to the statistical level of the current scoring result database. it can. Thereby, the new service using the scoring result with respect to a song can be provided with respect to a user. This service is convenient because the user can grasp how much the evaluation of the singing ability based on the statistical level at the time when the user sang has changed at the current level.

The karaoke scoring method according to claim 1 described above may be realized by, for example, a karaoke device alone for performing karaoke music, or a plurality of karaoke devices are connected to a network. It may be realized by a so-called karaoke network system.

[Explanation of singing scoring process]
Next, a flow of a series of processes in which the karaoke commander 2 and the host server 5 cooperate to score a user's song will be described based on the ladder chart of FIG.

  FIG. 2 shows a sequence of processing until the karaoke commander 2 scores a song, the host server 5 statistically calculates the correction score based on the grading result, and the karaoke commander 2 displays the correction score. It is a ladder chart which shows.

  First, the karaoke commander 2 starts playing karaoke music reserved by the user. The karaoke commander 2 according to the present embodiment accepts a login procedure from a user who has an account for logging in to the karaoke scoring system 1 according to the present embodiment, thereby allowing various karaoke commands such as reservation of music to be played, performance, and scoring. The service can be associated with the identification information (user ID) of the login user. More specifically, when the user starts using the karaoke commander 2, a login procedure for the karaoke commander 2 is performed. The login procedure to the karaoke commander 2 is performed by inputting an authentication user ID and password using a remote controller or the like associated with the operation terminal dedicated to the karaoke commander 2. The karaoke commander 2 then associates the user with the user who has logged into the device. Specifically, as the login user who is using the own karaoke commander 2, the user ID of the login user is stored in the RAM 22 or the like.

  The karaoke commander 2 scores the singing voice of the user input via the microphone 27 after starting the performance of the karaoke music reserved by the user. The scoring is performed by scoring the degree of matching between the user's singing voice and the scoring reference melody. And the scoring result in a singing period is totaled, The real score with respect to the said song is calculated by the scoring method which makes a perfect score 100 points | pieces, for example.

  The karaoke commander 2 transmits information indicating the scored actual score, the user ID of the sung user, the song number of the sung song, and the date and time of singing to the host server 5 as the singing result of the user. To do. When the host server 5 receives the scoring result from the karaoke commander 2, the host server 5 records the actual score included in the scoring result as a sample of the actual score of the music in the total music total data.

  Here, the detailed contents of the total music total data managed by the host server 5 will be described with reference to FIG. FIG. 3 is an explanatory diagram schematically showing an example of the total music total data stored in the host server 5.

  The total music total data is a data file in which the actual number of scoring results transmitted from each karaoke commander 2 is totaled for each scored music, and is stored in a database provided in the host server 5. As shown in FIG. 3, the total music total data includes “accumulated data number”, “average score”, “standard deviation”, “1”, “song number” column, which is music identification information. Columns such as “2”... “N” are provided. In the “number of stored data” column, the number of samples of the actual number stored for each music is recorded. In the “average score” column, an average value obtained by dividing the total of the actual scores for each music by the number of accumulated data is recorded. In the “standard deviation” column, a standard deviation value for a set of real scores for each music is recorded. In addition, in each of the columns “1”, “2”... “N”, individual real points for each music are recorded.

Further, the total music total data records the average score and standard deviation values of all music, which are the total of the actual scores for each music.
When the scoring result is transmitted from the karaoke commander 2, the host server 5 records the actual score included in the scoring result in the corresponding music number column of the total music total data, and the average score and standard for each music. The deviation, the average score of all songs and the standard deviation are calculated and recorded in the total song data.

  Returning to the description of the ladder chart of FIG. The host server 5, after registering the scoring result notified from the karaoke commander 2 in the total music total data, the average score and standard deviation of the music related to the scoring result recorded in the total music total data, and the total music Is used to calculate a correction score obtained by statistically correcting the actual score of the scoring result according to the difficulty level of the music. Here, a correction score higher than the actual score is calculated for a song with a relatively high difficulty level, and a correction score lower than the actual score is calculated for a song with a relatively low difficulty level. The The detailed contents of the correction point calculation method will be described later. After calculating the correction score, the host server 5 records various data related to the user's scoring result and the correction score in the personal history data.

  Here, the detailed contents of the personal history data managed by the host server 5 will be described with reference to FIG. FIG. 4 is an explanatory diagram schematically showing an example of personal history data stored in the host server 5.

  The personal history data is a data file in which the singing grading history of each individual user is collected in association with the user ID, and is stored in a database provided in the host server 5. As shown in FIG. 4, the personal history data is associated with the user ID, “number of histories”, “music number”, “singing date”, “singing time” that is identification information of the music sung by the user. , “Real score”, “correction score”, “average score for each song at singing”, “standard deviation for each song at singing”, “average score for all songs at singing”, “all songs at singing” A column such as “standard deviation of” is provided. A record having such a configuration is prepared for each individual user and stored in the database of the host server 5.

  In the “number of histories” column, the registered number of songs sung by the user is recorded. Also, the date and time when the song was sung are recorded in the “Singing Date” and “Singing Time” fields, respectively. In the “actual score” column, the actual score scored by the karaoke commander 2 at the time of singing the music is recorded. In the “correction score” column, the above-described correction score calculated by the host server 5 at the time of singing the music is recorded. In addition, each column of “average score for each song at singing”, “standard deviation for each song at singing”, “average score for all songs at singing” and “standard deviation of all songs at singing” The average score and standard deviation of the music and the average score and standard deviation of all the music based on the total music total data at the time of singing the music are respectively recorded.

  After calculating the correction score based on the scoring result notified from the karaoke commander 2 and the total music total data, the host server 5 relates to the scoring result in the above-mentioned fields of the record corresponding to the user of the personal history data. Add each piece of data about the song.

  Returning to the description of the ladder chart of FIG. After recording the personal history data, the host server 5 calculates the ranking of the correction score related to the scoring result in the song and the ranking in all the songs. In calculating the ranking, the correction scores for all users calculated in the past are aggregated for each music piece and stored in the database, and the set of stored correction scores is compared with the newly calculated correction scores. Thus, it is conceivable to calculate the ranking for each song and the ranking for all songs.

Next, the host server 5 returns the calculated correction score, the ranking for each song, and the ranking for all songs to the karaoke commander 2 as the scoring result transmission source.
When receiving the correction score from the host server 5, the karaoke commander 2 calculates the ranking of the received correction score in the karaoke store. In calculating the ranking in the karaoke store, the correction score for the singing performed in each karaoke commander 2 in the karaoke store in the past is aggregated and accumulated in the database in the karaoke commander 2 and stored. It is conceivable to calculate the rank in the karaoke store by comparing the set of correction points with the newly received correction points.

  Then, the karaoke commander 2 displays the correction score received from the host server 5, the ranking for each song, the ranking for all the songs, and the ranking in the store calculated on the display unit 26 as the final result of scoring the song. indicate.

[Description of scoring process executed by Karaoke Commander 2]
Next, detailed contents of the processing executed by the karaoke commander 2 in the above-described series of processing shown in the ladder chart of FIG. 2 will be described with reference to FIGS. 5 and 6.

  FIG. 5 is a flowchart showing the procedure of the scoring process executed by the karaoke commander 2. This process is a process executed when the karaoke commander 2 plays the music reserved from the login user in the scoring mode.

  The karaoke commander 2 first starts playing the reserved music in a scoring mode in which singing is performed (S100), and scores the user's singing voice input from the microphone 27 (S110). Then, it is determined whether or not the music has been played (S120). While the performance of the music continues (S120: NO), the singing voice is continuously scored in S110. Then, when it determines with the performance of the said music having been complete | finished (S120: YES), the scoring result during a song period is totaled, and the real score with respect to the said song is calculated (S130).

  And the data which shows the user ID which is the identification information of the user who performed the singing, the music number which is the identification information of the sung music, the actual score for the singing, and the date and time of singing is sent to the host server 5 as a scoring result. Transmit (S140). Subsequently, it waits until a correction score and rank response is received from the host server 5 (S150-S160: NO).

  If it is determined in S160 that a response from the host server 5 has been received (S160: YES), the ranking of the correction score received from the host server 5 in the karaoke store is calculated (S170). Then, the correction score received from the host server 5, the ranking for each song, the ranking for all the songs, and the ranking in the store calculated in S170 are displayed together with the user name and the song name as the final result of scoring for the song. 26 is displayed for a predetermined time (for example, 5 seconds) (S180), and this process is terminated.

FIG. 6 is an explanatory diagram schematically showing a display example of the scoring results in S180.
As shown in FIG. 6, on the scoring result display screen, along with the name of the singer and the name of the song sung, the score of the scoring result (correction score), the ranking in the store, the ranking for each song, the national ranking ( Ranking in all songs) is displayed.

[Description of scoring correction / history recording process executed by host server 5]
Next, detailed contents of processing executed by the host server 5 in the series of processing shown in the ladder chart of FIG. 2 will be described with reference to FIGS.

FIG. 7 is a flowchart showing a procedure of scoring correction / history recording processing executed by the host server 5. This process is a process that is repeatedly executed in the host server 5 at all times.
First, the host server 5 stands by until a scoring result notification is received from the karaoke commander 2 (S200-S210: NO). The scoring result notification is transmitted in S140 of the scoring process described above (see FIG. 5). Thereafter, when it is determined that the notification of the scoring result has been received from the karaoke commander 2 (S210: YES), the scoring result is displayed in the corresponding music column of the total music data stored in the database (see FIG. 3). The actual number of points is recorded (S220).

  Next, the average score and standard deviation values for each song and the average score and standard deviation values for each song are read out from the data in each column related to the song in the total music data, and these values are used. A correction score for the actual score included in the scoring result is calculated (S230). Specifically, using these values, the deviation value of the actual score of the scoring result relative to the set of actual scores of the music in the total music total data and the set of real scores of all the music in the total music total data are used as a mother. A correction score is calculated such that the deviation value of the correction score as a group is equal. That is, the correction score x is calculated on the assumption that the following equation (1) is satisfied. As a result, the actual score of the scoring result can be corrected from the level of deviation value for each music piece to a point corresponding to the level of deviation value of all music pieces.

そして、上記式（１）を変形することで、補正点数ｘは下記の式（２）によって算出できる。

Then, by modifying the above equation (1), the correction score x can be calculated by the following equation (2).

なお、上記式（１），（２）において、μは全楽曲の平均点数を示し、σは全楽曲の標準偏差を示している。また、当該採点結果に該当する楽曲ｉの実点数を示し、μｉは楽曲ｉの平均点数を示し、σｉは楽曲ｉの標準偏差を示している。

In the above formulas (1) and (2), μ represents the average score of all songs, and σ represents the standard deviation of all songs. Further, the actual score of the music i corresponding to the scoring result is shown, μi is the average score of the music i, and σi is the standard deviation of the music i.

Here, a specific example of the calculation result of the correction score by the above equation (2) will be described with reference to FIGS.
It is assumed that the set of real scores of all the music exhibits a score distribution with an average score of 80 as shown in FIG. Here, it is assumed that a set of real scores of a certain music piece A exhibits a score distribution with an average score of 87 as shown in FIG. In this case, the actual score of the music A is distributed in a range of scores higher than 80, which is the average score of all the music, and it can be estimated that the music A is a relatively simple music.

  Now, suppose that Mr. X who sang song A has 92 points. Mr. X's actual score is higher than the average score of song A, 87 points, but the correction score for Mr. X's actual score is 88 points, and is corrected downward to a score lower than the actual score. However, Mr. X's correction score exceeds the average score of all songs. On the other hand, suppose that Mr. Y who sang music A has 82 points. The actual score of Mr. Y is higher than the average score of 80 for all songs, but is lower than the average score of music A. In this case, the correction score for Mr. Y's actual score is 68 points, which is corrected downward to a score that is lower than the average score of 80 points for all songs.

  Next, in FIG. 9, it is assumed that a set of real scores of a certain music piece B exhibits a score distribution with an average score of 75 points. In this case, the actual score of the music B is distributed more in the range of the score lower than 80, which is the average score of all the music, and it can be estimated that the music B is a relatively difficult music.

  Now, suppose that Mr. X who sang music B has 78 points. Mr. X's actual score is higher than the average score of music B by 75 points, but is lower than the average score of all music by 80 points. In this case, Mr. X's actual score is upwardly corrected to a score that exceeds the average score of 80 for all music pieces, and the corrected score is 88 points. On the other hand, suppose that Mr. Y who sang music B had 73 points. Mr. Y's actual score is lower than both the average score of all songs and the average score of song B. In this case, although Mr. Y's actual score is corrected upward to a correction score of 76 points, the score remains lower than the average score of 80 points for all music pieces.

  Returning to the flowchart of FIG. After calculating the correction score for the actual score of the scoring result in S230, the music number, singing date, and singing related to the scoring result are displayed in each column of the record corresponding to the user of the personal history data (see FIG. 4). Record the time, the actual score, the correction score, the average score and standard deviation of the song at the time of singing, and the average score and standard deviation of all the songs at the time of singing (S240).

  Next, the rank of each correction piece calculated in S240 and the rank of all the pieces are calculated (S250). Then, the correction score, the ranking for each song, and the ranking for all the songs are returned to the karaoke commander 2 that is the transmission source of the scoring results (S260), and this processing is terminated.

Next, a flow of a series of processes in which the karaoke commander 2 and the host server 5 cooperate to display the personal scoring history will be described based on the ladder chart of FIG.

  In FIG. 10, the karaoke commander 2 accepts a personal scoring history browsing request from the user, and the host server 5 transmits history data to the karaoke commander 2 in response to the viewing request, and the karaoke commander 2 displays the scoring history. It is a ladder chart which shows the procedure of a series of processes until.

  First, when the karaoke commander 2 is instructed by a user to display a personal scoring history (hereinafter also referred to as a personal history), the karaoke commander 2 transmits a personal history transmission request including the user ID of the user to the host server 5. .

  When the host server 5 receives the personal history transmission request from the karaoke commander 2, the host server 5 reads a record corresponding to the user ID included in the personal history transmission request from the personal history data (FIG. 4). Next, the latest correction score based on the current total music total data (see FIG. 3) is recalculated with respect to the actual score of each music included in the read record. Then, the music number read from the personal history data of the user, the correction score at the time of singing, and the recalculated correction score are returned as history data to the karaoke commander of the personal history request source.

When the karaoke commander 2 receives the history data from the host server 5, the karaoke commander 2 displays the contents on the display unit 26.
[Description of personal history display processing executed by Karaoke Commander 2]
Next, the detailed content of the process which the karaoke commander 2 performs among the above-mentioned series of processes shown in the ladder chart of FIG. 10 is demonstrated based on FIG.11 and FIG.12.

  FIG. 11 is a flowchart showing the procedure of the personal history display process executed by the karaoke commander 2. This process is started when the karaoke commander 2 receives an instruction to display the personal history from the user.

  The karaoke commander 2 first transmits a personal history transmission request to the host server 5 based on an instruction for displaying the personal history received from the user (S300). This personal history transmission request includes the user ID of the user who instructed the display of the personal history.

  After transmitting the personal history transmission request to the host server 5, the system waits until a history data response is received from the host server 5 (S310-S320: NO). If it is determined that a history data response has been received from the host server 5 (S320: YES), the received history data is recorded in the RAM 22 (S330).

  Next, based on the recalculated correction score of each piece of music included in the history data received from the host server 5, the ranking of the correction score in the store is calculated (S340). Then, the correction score at the time of singing each song included in the history data, the recalculated new correction score, and the in-store ranking based on the new correction score are displayed on the display unit 26 together with the name of the music and the user name. It is displayed (S350). It should be noted that information displayed at this time is information for five pieces of music included in the history data.

FIG. 12 is an explanatory diagram schematically showing a display example of the personal history in S350.
As shown in FIG. 12, the scoring result display screen includes the name of each singer, the name of each song sung, the correction score at the time of singing the song, the recalculated new correction score, and the new correction score. The order in the store is displayed. If the history data received from the host server 5 includes data for five or more songs, the user is guided through the operation for switching the personal history display screen to the next song page. Display to the effect. In the present embodiment, by pressing the “song selection” button for reserving a performance song provided on the operation unit 25 of the karaoke commander 2 or a remote control provided in the karaoke commander 2, It is assumed that the display screen is configured to be switched to the next page. In addition, it is assumed that the browsing of the personal history can be ended by pressing a “stop performance” button for stopping the performance of the music.

  Returning to the flowchart of FIG. After the personal history is displayed in S350, it is determined whether or not the “Song Selection” button has been pressed (S360). If it is determined that the “Song Selection” button has been pressed (S360: YES), the currently displayed personal history is switched to the content of the next five songs based on the history data stored in the RAM 22 (S370). , The process returns to S360.

  On the other hand, if it is determined in S360 that the “Song Selection” button has not been pressed (S360: NO), it is determined whether or not the “Performance Stop” button has been pressed (S380). If it is determined that the “stop performance” button has not been pressed (S380: NO), the process returns to S360. On the other hand, if it is determined that the “stop performance” button has been pressed (S380: YES), the display of the personal history is terminated (S390), and then this process is terminated.

[Description of history data transmission processing executed by host server 5]
Next, detailed contents of processing executed by the host server 5 in the series of processing shown in the ladder chart of FIG. 10 will be described with reference to FIG.

FIG. 13 is a flowchart showing a procedure of history data transmission processing executed by the host server 5. This process is a process that is repeatedly executed in the host server 5 at all times.
First, the host server 5 stands by until a personal history transmission request is received from the karaoke commander 2 (S400-S410: NO). The personal history transmission request is transmitted in S300 of the above-described personal history display process (see FIG. 11). Thereafter, when it is determined that a personal history transmission request has been received from the karaoke commander 2 (S410: YES), a record corresponding to the user ID included in the personal history transmission request is read from the personal history data (FIG. 4) ( S420).

  Next, the latest correction score based on the current total song data (see FIG. 3) is recalculated for the actual score of each song included in the read record (S430). The correction score calculation method is the same as the correction score calculation method using the above equation (2) in S230 of the above-described scoring correction / history recording process (see FIG. 7). Then, the music number of each music read from the user's personal history data, the correction score at the time of singing, and the recalculated correction score are returned as history data to the karaoke commander of the personal history request source (S440).

[effect]
According to the karaoke scoring system 1 of the above embodiment, the following effects can be obtained.
Deviation value of the real score of the scoring result with the set of real scores corresponding to the music related to the singing score as the population, and deviation value of the correction score with the set of real scores corresponding to all the music as the population By calculating the correction score so that the values are equal, the actual score of the scoring result can be corrected from the level of the deviation value for each music piece to the point corresponding to the level of the deviation value of all music pieces. Thereby, the skill of a user's song can be scored correctly and fairly in the aspect which considered the statistical characteristic of the real score which arises with the difficulty for every music. In addition, it is preferable that the user can accurately grasp his / her singing ability by presenting the score corrected by such a method to the user.

  In addition, by adding up the correction scores calculated in this way and using this aggregated data for ranking the scoring results, even if the scoring results for multiple songs with different levels of difficulty are summed up, Ranking can be performed based on a fair score obtained by correcting the score difference due to the difference in degree.

  Furthermore, in the karaoke scoring system 1 of the above-described embodiment, the personal scoring history accumulated in the personal history data can be browsed in response to a viewing request from the user. In addition, in this browsing, it is possible to compare the past correction score calculated at the time of singing with the correction score obtained by newly correcting the actual score at the time of singing according to the statistical level of the current scoring result database. it can. Thereby, the new service using the scoring result with respect to a song can be provided with respect to a user. This service is convenient because the user can grasp how much the evaluation of the singing ability based on the statistical level at the time when the user sang has changed at the current level.

  In the karaoke scoring system 1 of the above embodiment, the karaoke scoring method of the present invention is connected to a plurality of karaoke commanders 2 for scoring singing and a host server 5 for calculating a correction score based on a scoring result database. Applied to the system. In such a system, since the scoring results are uploaded from the plurality of karaoke commanders 2 to the host server 5, many scoring result samples can be accumulated in the total music total data. Therefore, more accurate and fair scoring based on more samples can be realized as compared with the case where the karaoke scoring system of the present invention is realized by a single karaoke apparatus that performs karaoke music.
