Description

  The present invention relates to a performance evaluation system and a performance evaluation processing program, and more particularly, to a performance evaluation system and a performance evaluation processing program for performing communication between a server and a terminal device connected via a network.

Accompanying dramatic advances in communication networks in recent years, communication between terminal devices and servers connected via a network such as the Internet is performed, and evaluation of music practice performed by users on terminal devices is evaluated. Systems such as those performed by servers are becoming popular.
For example, in a proposed karaoke device, in order to tell the level of scoring results of singing karaoke songs, the total number of singers who actually sang was counted. Displays the ranking in the middle. Alternatively, a temporary ranking such as a number among 1000 people is calculated and displayed based on the average score and standard deviation of the song (see Patent Document 1).
In addition, according to another proposed singing ability determination device, voice data input simultaneously and frequently from a plurality of terminal karaokes distributed throughout the country are scored or ranked simultaneously in the center, and the results are immediately received. Displayed on individual terminal karaoke devices. For this purpose, the singing voice data of the singer is transmitted to the center in a form synchronized with the accompaniment music data. The center's computer compares the pitch, rhythm, strength, etc. of each pre-recorded and stored model song to each time-divided section for each identical song / accompaniment, and immediately follows a predetermined scoring standard. To score. The scored result is returned to an individual karaoke terminal device together with rank data and comments calculated for each genre by a pre-installed program and displayed on the screen (see Patent Document 2).
Furthermore, in another proposed karaoke apparatus, in order to accurately compare and evaluate a singer's current singing ability on a nationwide scale, the user interface registers a specified song in a queue, and the communication means is a host. The communication means communicates with the apparatus, and the control means enables download processing and display processing. When the music that is registered in the queue is played, the download means obtains the score ranking information of the music from the host device by the communication means, and the display processing. Displays the scoring information output by the scoring means in association with the scoring ranking (Patent Document 3).

After transmitting data in response to a request from the electronic musical instrument 1 or reception of data, the process again proceeds to step SK1 in FIG. 19 and the above processing is repeated.

As described above, according to this embodiment, the CPU 11 of the electronic musical instrument 1 selects an input performance rank of one stage from a plurality of performance ranks from upper to lower with respect to the performance of the music data. When a command for setting, scoring performance data input for the song data and requesting a rank for the scored performance data is input, the scored performance data is the highest performance rank. In this case, the scoring results are transmitted to the server 3 connected via the network 2, and the ranking of the scoring results is received from the server 3 and displayed.
Therefore, when the server performs communication between a number of terminal devices connected via a network and the server, and the server evaluates music practice in each terminal device, the performance rank is lower than the highest performance rank. In this case, since the scoring result is not transmitted, it is possible to avoid network blockage and server system down due to congestion of communication traffic.

In this case, the CPU 11 sets the performance rank of karaoke singing power for the song data. Alternatively, the performance rank of the keyboard performance for the song data is set.
Therefore, when the server evaluates music practice for various performances, it is possible to avoid network blockage and server system down due to congestion of communication traffic.
Further, when a command for registering the scoring result in the server 3 is input, the scoring result is transmitted to the server 3.
Therefore, even if the scored performance data is the highest performance rank, the scoring result is not transmitted if the user does not intend to register, so that personal information can be prevented from leaking against the intention of the user.

In addition, the CPU 11 scores performance data based on a higher scoring standard as the set performance rank stage is higher.
Therefore, strict scoring is performed for performances of higher performance ranks to maintain the reliability of the ranking, and flexible and acceptable scoring is performed for performances of lower performance ranks. The user's willingness to play is not reduced.

In the above embodiment, the performance rank of three stages is set for the performance of the music data, but it may be two stages or four or more stages. Further, the electronic musical instrument may automatically set the performance rank according to the scoring result without setting the performance rank by the user's selection.
Moreover, in the said embodiment, although it was set as the structure which scores singing ability of karaoke, you may make it the structure which scores the pitch etc. in speaking practice, such as a musical and an opera. In addition to the performance of the keyboard, the type and timing of the instrument in the performance of the percussion instrument may be scored.

  In the above embodiment, the invention in which the CPU 11 executes the performance evaluation processing program stored in advance in the program ROM 13 of the electronic musical instrument 1 has been described. However, a writable non-volatile memory such as a flash memory is used as the electronic memory. A configuration in which a program for performance evaluation processing read from a CD-ROM or a memory card or a program for performance evaluation processing downloaded from a network is installed in a non-volatile memory and executed in a musical instrument is also possible. In this case, the invention of the program, the invention of the storage medium, and the invention of the performance evaluation method are realized.

The performance evaluation processing program of the present invention is:
Step A for setting the performance rank of one input stage from a plurality of performance ranks from the upper to the lower order for the performance of the music data, and scoring the performance data input for the music data Step B and a command for requesting a rank for the performance data scored in Step B are input, it is determined whether or not the performance rank set in Step A is a predetermined performance rank. Step C, and when the step C determines that the performance rank is the predetermined performance rank, the score result of the step B is transmitted to a server connected via the network, and the ranking of the score result Is received from the server and displayed on the display means.

The step A sets the performance rank of the singing ability of karaoke for the song data, and the step B scores the voice data of the input song.
The step A is characterized in that a performance rank of keyboard performance for music data is set.
In the step D, when a command for registering the scoring result in the server is input, the scoring result is transmitted to the server.
The step B is characterized in that the performance data is scored with a higher scoring standard as the rank of the performance rank set in the step A is higher.
