To be executed. Further, the inter-process communication is possible between the temporary recording process and the chorus sound data transmission process.

First, the temporary recording process will be specifically described with reference to the flowchart of FIG.
In S <b> 21, the control unit 201 of the server 200 sequentially records the received determination song sound data in the temporary recording unit 204.
In S22, it is determined whether or not a recording stop instruction has been issued. The recording stop instruction is issued from the chorus sound data transmission process. In this process, when it is determined that there is no recording stop instruction (S22: NO), the control unit 201 returns the process to S21. Thereby, the singing sound data for determination is sequentially recorded in the temporary recording unit 204 until a recording stop instruction is issued. On the other hand, when it is determined that there is a recording stop instruction (S22: YES), the control unit 201 ends the temporary recording process.

Next, the repeated sound data transmission processing will be described with reference to the flowchart of FIG.
In S31, the control unit 201 executes part determination processing.
Hereinafter, the part determination process will be described with reference to the flowchart of FIG.

In S <b> 41, the control unit 201 reads the determination singing sound data from the temporary recording unit 204.
In S <b> 42, the control unit 201 reads out the main melody reference data of the same music as the determination singing sound data from the karaoke music database 202 and compares it with the determination singing sound data using a known technique.
In S43, the control unit 201 reads out the reference data of the same music as the singing sound data for determination from the karaoke music database 202 and compares it with the singing sound data for determination using a known technique.

In S44, the control unit 201 determines whether or not the part determination of the singing sound data for determination has been made based on the comparison result of S42 and S43. In this process, when it is determined that the part determination cannot be performed (S44: NO), the control unit 201 shifts the process to S45.
In S45, the control unit 201 determines whether or not a predetermined time has elapsed since the start of the part determination process. In this process, when it is determined that the predetermined time has not elapsed (S45: NO), the control unit 201 returns the process to S41. On the other hand, in this process, when it is determined that the predetermined time has elapsed (S45: YES), the control unit 201 shifts the process to S46.

  In step S46, the control unit 201 executes error processing. In the error process, the control unit 201 creates display data indicating that the part determination cannot be performed within a predetermined time, and transmits the display data to the karaoke apparatus 100. Moreover, in the karaoke apparatus 100, the process for making a singer select the sung part can be performed. Moreover, the control part 201 will complete | finish a chorus sound data transmission process, after complete | finishing an error process.

On the other hand, if it is determined in S44 that the part has been determined and the part is determined to be a main melody part, the control unit 201 shifts the process to S47.
In step S <b> 47, the control unit 201 sets a “harm” value indicating that the repeated sound data of the hammer part is to be provided to the “providing flag” reserved in the RAM in the control unit 201.
In S44, if it is determined that the part has been determined and it is determined that the part is a hammer part, the control unit 201 shifts the process to S48.
In S <b> 48, the control unit 201 sets a “main melody” value indicating that the chord sound data of the main melody part is to be provided in the “provide flag”.

Returning to FIG.
In S <b> 32, the control unit 201 performs a chorus sound data determination process.
Hereinafter, the repeated sound data determination process will be described with reference to the flowchart of FIG.

  In S <b> 61, the control unit 201 determines whether or not the provision flag is “harm” (that is, whether or not the hammer part repeated sound data should be provided). In this determination, when it is determined that the provision flag is “harm” (S61: YES), the control unit 201 shifts the process to S62.

In step S <b> 62, the control unit 201 determines whether or not post-song sound data (hereinafter referred to as “hemo-tune data”) of the humming part of the same music as the determination singing sound data has been posted to the posted singing sound database 203. . In this process, when it is determined that the same song music data is posted (S62: YES), the control unit 201 shifts the process to S63.
In S <b> 63, the control unit 201 extracts the humor song data of the same song from the posted singing sound database 203 and records it in the temporary recording unit 204 as “candidate data”. In S63, it is assumed that a plurality of pieces of song music data are extracted.

  In S <b> 64, the control unit 201 converts the determination singing sound data (main melody part) into a hammer part and records it as “reference data” in the temporary recording unit 204. That is, reference data is created. As shown in FIG. 8, the difference value between the hamori reference data and the main melody reference data recorded in the karaoke song database 202 is added to the main melody part data (determining singing sound data) to obtain the hamori part data. Can be generated. Note that the hamori part data may be generated from the main melody part data by another known method. Further, the process in S64 is continuously performed every time the singing sound data for determination is newly written in the temporary recording unit 204. That is, the singing sound data for determination received after the end of the part determination process (S31 in FIG. 5) is also sequentially converted into a hammer part and recorded in the temporary recording unit 204 as “reference data”.

In step S65, the control unit 201 executes a provided data selection process. By the provided data selection processing, “candidate data” that is most similar to the singing sound data for determination converted into the hammer part is selected from the “candidate data” (hammori song data) in S63. Then, the selected “candidate data” becomes “single sound data” transmitted to the karaoke apparatus 100. Details of the provided data selection process will be described later. In S63, when only one piece of song data is extracted, the processing of steps S64 and S65 is not executed, and the one piece of song data becomes “song sound data” transmitted to the karaoke apparatus 100. .
Hereinafter, the series of processes of S64 and S65 may be referred to as “first process”.

Further, the “repeated sound data” can also be determined by the following processing (the following processing may be referred to as “second processing”).
(1) The hamori song data extracted in S63 is converted into post melody data of the main melody part (hereinafter referred to as “main melody data”), and the converted main melody data is set as “candidate data”. The “candidate data” is used for comparison with the determination singing sound data (main melody part). As shown in FIG. 9, the data of the main melody part can be generated by adding the difference value between the hammer reference data and the main melody reference data recorded in the karaoke song database 202 to the hammer song data. It should be noted that the conversion of the main song data from the hammer song data may be performed by other known methods.
(2) Record the singing sound data for determination as “reference data” in the temporary recording unit 204, and execute the provided data selection process. Thereby, one data is determined from among a plurality of candidate data, and the humor song data corresponding to the determined candidate data (main melody data) becomes the “song sound data” transmitted to the karaoke apparatus 100. Also, the determination singing sound data received after the part determination process (S31 in FIG. 5) is also sequentially recorded in the temporary recording unit 204 as “reference data”.

Here, when the first process is used, the part conversion process (main melody part → hamo part) is performed only on the determination singing sound data, so the processing amount is small and the load on the server 200 can be reduced. it can.
On the other hand, when the second process is used, the amount of processing increases because the part conversion process (harmory part → main melody part) is performed on a plurality of posted singing sound data, but this is a criterion for selecting provided data. Since the singing sound data for determination is used as it is as “reference data” (that is, the processing is not performed on the singing sound data for determination), the provided data selection process with high accuracy can be performed.

  Further, both the first processing and the second processing may be executed, and the processing may be switched according to the load of the server 200. In other words, the first process may be executed when the load on the server 200 is high, and the second process may be executed when the load is not so.

On the other hand, in S62, when it is determined that the same song music data is not posted (S62: NO), the control unit 201 shifts the process to S66.
In S <b> 66, it is determined whether or not the main melody data of the same music as the determination singing sound data is posted in the posted singing sound database 203. In this process, when it is determined that the main melody data of the same music is posted (S66: YES), the control unit 201 shifts the process to S67.

In step S <b> 67, the control unit 201 extracts main melody data of the same music from the posted singing sound database 203. In S67, a plurality of main melody data are extracted. The extracted main melody data is recorded in the temporary recording unit 204 as “candidate data”. Note that the singing sound data for determination is recorded in the temporary recording unit 204 as “reference data”, and the singing sound data for determination received after the part determination process (S31 in FIG. 5) is also sequentially performed. It is recorded in the temporary recording unit 204 as “reference data”.
In S68, the control unit 201 executes a provided data selection process. One data (main melody data) is determined from the plurality of candidate data by the provided data selection process.

In S69, the control unit 201 converts the main melody data determined in S68 into hammer song data.
Also, the converted song data data becomes “singing sound data” transmitted to the karaoke apparatus 100.

On the other hand, when it is determined in S66 that the main melody data of the same music as the singing sound data for determination is not posted (S66: NO), the control unit 201 shifts the process to S70.
In S <b> 70, the control unit 201 extracts singing sound data of the same music from the karaoke music database 202. The extracted singing sound data becomes “single sound data” transmitted to the karaoke apparatus 100.

  On the other hand, in S61, when it is determined that the provision flag is not “harm” (that is, “main melody”) (S61: NO), the control unit 201 shifts the process to S71.

In S <b> 71, the control unit 201 determines whether or not the main melody data of the same music as the determination singing sound data is posted in the posted singing sound database 203. In this process, when it is determined that the main melody data of the same music is posted (S71: YES), the control unit 201 shifts the process to S72.
In S <b> 72, the control unit 201 extracts the main melody data of the same music from the posted singing sound database 203 and records it as “candidate data” in the temporary recording unit 204. In S72, a plurality of main melody data are extracted.

  In step S <b> 73, the control unit 201 converts the singing sound data for determination (hamo part) into a main melody part, and records it in the temporary recording unit 204 as “reference data”. That is, reference data is created. Moreover, the process in S73 shall be performed continuously whenever the song data for determination is newly written in the temporary recording part 204. FIG. That is, the singing sound data for determination received after the part determination processing (S31 in FIG. 5) is also sequentially converted into the main melody part and recorded in the temporary recording unit 204 as “reference data”.

In step S74, the control unit 201 executes a provided data selection process. By the provided data selection process, “candidate data” most similar to the singing sound data for determination converted into the main melody part is selected from the “candidate data” (main melody data) in S72. Then, the selected “candidate data” becomes “choral sound data” transmitted to the karaoke apparatus 100. Further, when only one main melody data is extracted in S71, the processing of S73 and S74 is not executed, and the one main melody data becomes “song sound data” transmitted to the karaoke apparatus 100. .
Hereinafter, the series of processes of S73 and S74 may be referred to as “third process”.

In addition, the “repeated sound data” can be determined by the following processing (the following processing may be referred to as “fourth processing”).

(2) Record the singing sound data for determination as “reference data” in the temporary recording unit 204, and execute the provided data selection process. Thereby, one data is determined from among a plurality of candidate data, and the main melody data corresponding to the determined candidate data (humor song data) becomes “repeated sound data” transmitted to the karaoke apparatus 100. Also, the determination singing sound data received after the part determination process (S31 in FIG. 5) is also sequentially recorded in the temporary recording unit 204 as “reference data”.

Here, when the third process is used, the part conversion process (harm part → main melody part) is performed only on the determination singing sound data, so the processing amount is small and the load on the server 200 can be reduced. it can.
On the other hand, when the fourth process is used, the amount of processing increases because part conversion processing (main melody part → humor part) is performed on a plurality of posted singing sound data, but this is a criterion for selecting provided data. Since the singing sound data for determination is used as it is as “reference data” (that is, the processing is not performed on the singing sound data for determination), the provided data selection process with high accuracy can be performed.

  Further, both the third process and the fourth process may be executed, and the process may be switched according to the load of the server 200. In other words, the first process may be executed when the load on the server 200 is high, and the second process may be executed when the load is not so.

On the other hand, when it is determined in S71 that the main melody data of the same music has not been posted (S71: NO), the control unit 201 shifts the process to S75.
In S <b> 75, it is determined whether or not the humming song data of the same song as the determination singing tone data is posted in the posted singing tone database 203. In this process, when it is determined that the same song music data has been posted (S75: YES), the control unit 201 shifts the process to S76.

In step S <b> 76, the control unit 201 extracts hamori music data of the same music from the posted singing sound database 203. In S76, a plurality of main melody data are extracted. Further, the extracted song music data is recorded in the temporary recording unit 204 as “candidate data”. Note that the singing sound data for determination is recorded in the temporary recording unit 204 as “reference data”, and the singing sound data for determination received after the part determination process (S31 in FIG. 5) is also sequentially performed. It is recorded in the temporary recording unit 204 as “reference data”.
In step S77, the control unit 201 executes a provided data selection process. By the provided data selection processing, one data (harmong song data) is determined from among a plurality of candidate data.

  In S78, the control unit 201 converts the hammer music data determined in S77 into main melody data. Further, the converted main melody data is “single sound data” transmitted to the karaoke apparatus 100.

On the other hand, when it is determined in S75 that the same song music data as the determination singing sound data is not posted (S75: NO), the control unit 201 shifts the process to S79.
In step S <b> 79, the control unit 201 extracts singing sound data of the same music from the karaoke music database 202. The extracted singing sound data becomes “single sound data” transmitted to the karaoke apparatus 100.

Next, the provided data selection process will be described with reference to the flowchart of FIG.
In step S <b> 81, the control unit 201 acquires reference data and candidate data from the temporary recording unit 204.

This determination is made based on whether one candidate data closest to the determination singing sound data has been identified. For example, when a general karaoke scoring process is performed and one candidate data is stably in the highest rank in a plurality of time intervals, it can be determined that “one closest candidate data has been identified”. it can. In this process, when it is determined that the provision data can be determined (S83: YES), the control unit 201 ends the provision data selection process. On the other hand, when determining that the provided data cannot be determined (S83: NO), the control unit 201 shifts the process to S84.

In S84, the singing sound data for determination is acquired from the temporary recording unit 204. The determination singing sound data acquired in this process is the determination singing sound data newly recorded in the temporary recording unit 204 by the temporary recording process.
In S85, the control unit 201 compares the reference data with the candidate data.

  In S <b> 86, the control unit 201 determines whether or not the provision data can be determined among the candidate data. In this process, when it is determined that the provision data can be determined (S86: YES), the control unit 201 ends the provision data selection process. On the other hand, when determining that the provided data cannot be determined (S86: NO), the control unit 201 returns the process to S84. Thus, until the provision data is determined, the comparison with the candidate data is performed based on the singing sound data for determination newly recorded in the temporary recording unit 204.

Returning to FIG.
In S33, a recording stop instruction is issued to instruct to stop recording in the temporary recording process.
In S <b> 34, the data for heavy singing determined by the data determination processing for heavy singing is transmitted to the karaoke apparatus 100.

  As described above, according to the present embodiment, when the singing sound data for determination is determined to be the main melody part (harmonic part), the posted singing sound data of the harmony part (main melody part) suitable for repeated singing is recorded. In this case, the singing voice based on the posted singing sound data is output when the karaoke music piece is played. Furthermore, when there is no post singing sound data of a harmony part (main melody part) suitable for repeated singing, the post singing sound data of the main melody part (harmony part) is selected, and the harmony part (singing part) generated from the singing sound data is selected. Singing sound based on the singing sound data of) is output when the karaoke music is played. Thereby, the posted singing sound data can be effectively used when singing.

  Moreover, since the suitable chorus sound data for a chorus is selected based on the singing sound data for determination of a part of karaoke music, the burden on the singer can be reduced. Further, by comparing the candidate song data with the judgment song sound data as a reference for comparison, the song sound data transmitted according to the way of singing changes, so that the interest of the singer can be enhanced.

  The present invention is not limited to the above-described embodiment, and it goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.

Further, each flowchart described above is merely an example, and the processing may be realized by another flowchart as long as a result equivalent to the processing of each flowchart can be obtained.
Further, the present invention can be realized as each method relating to the above-described remote controller, commander, and server, a program for causing a computer to execute the method, a recording medium recording the program, and the like.
