<Processing on the client device>
Next, a processing procedure of karaoke music data creation processing executed by the control unit 20 (more precisely, the CPU 21) will be described.

Here, FIG. 2 is a flowchart showing the processing procedure of the karaoke song data creation processing.
This karaoke piece data creation process is started when a start instruction for the karaoke piece data creation process is input via the operation reception unit 14.

  Then, as shown in FIG. 2, when the karaoke song data creation process is started, first, in S110, the accompaniment song is selected from the plurality of accompaniment songs prepared in advance via the operation reception unit 14. If the accompaniment music selection is not accepted, the process waits until it is accepted.

  When the accompaniment music selection is accepted, the accompaniment music that has been accepted is reproduced and played (S120). Thereby, the component sound which forms the accompaniment music from the speaker 18 is emitted. In addition, the accompaniment music in this embodiment represents transition of the performance sound in the period corresponding to the specific period (here rust) in one music.

  Furthermore, voice data is acquired from the voice input unit 15 (S130). At this time, if the user sings along with the accompaniment music, the voice uttered by the user is acquired after being converted into voice data.

  Subsequently, the audio data acquired in S130 is subjected to frequency analysis, and the frequency analysis result (for example, frequency spectrum) and a comb-shaped structure model prepared in advance are collated with a known method. The fundamental frequency f0 for each unit period, that is, the pitch of the voice input through the microphone 17 is estimated. At the same time, the duration of each estimated pitch (hereinafter referred to as the tone length) is estimated using a known method (S140).

  Further, based on both the pitch and the length estimated in S140, the voice input through the microphone 17 during the performance of the accompaniment music is converted into a note, that is, scored (S150). Thereby, if the user is singing along with the accompaniment music, the voices uttered by the user are sequentially represented on the musical score.

  Subsequently, it is determined whether or not an end command indicating that the cycle from S130 to S150 (that is, Hamming composition) is to be ended is input via the operation reception unit 14 (S160). As a result of the determination, if the end command is not input, the process returns to S130, and if the end command is input, the process proceeds to S170.

  In S170, the result obtained in S150 is converted into partial music data representing a part of the whole period of one music data. That is, in S170, partial music data that is the source of one music data is generated. Since the process of converting the scored result into music data is well known, detailed description thereof is omitted here.

  Subsequently, a graphical user interface image (hereinafter referred to as a lyrics input image) for receiving input of characters is displayed on the display unit 13 (S180). When a sentence (that is, a character) is input via the operation receiving unit 14 to a preset inputable position in the lyrics input image, the input sentence (that is, a character) is received (S190).

  Further, it is determined whether or not an input completion command indicating completion of character input (ie, input of lyrics) via the lyrics input image has been acquired (S200). As a result of the determination, if an input completion command has not been input, the process returns to S180, and the text input reception via the operation reception unit 14 is continued. On the other hand, when an input completion command is input, an input completion signal indicating that the input completion command has been input and a sentence received in S190 (that is, a character, hereinafter referred to as an input sentence) are transmitted to the server device 30. To do.

  Subsequently, as will be described in detail later, the server device 30 divides each word / phrase (hereinafter referred to as an input word / phrase) in the input sentence received in S190 and searches for a synonym for each input word / phrase. And a synonym selection image SI (see FIG. 3) showing what is returned from the server device 30 is displayed on the display unit 13 (S210). The synonym selection image SI is a graphical user interface. As shown in FIG. 3, the synonym selection image SI is a character string display column 101 that displays the input text input in S190, and a plurality of synonyms or inputs returned from the server device 30. A phrase selection display 102 for selecting one of the phrases by a so-called pull-down menu method, and a confirmation completion command for confirming a phrase to be used as lyrics from a plurality of synonyms or input phrases And a completion command input display 103. A phrase selection display 102 (102A to 102D in the figure) is prepared for each input phrase. Therefore, a synonym for each input phrase is displayed in the synonym selection image SI.

  And the input with respect to the synonym selection image SI via the operation reception part 14 is received. (S220). In the subsequent S230, it is determined whether or not a confirmation completion command has been input via the operation receiving unit 14 in the previous S220. As a result of the determination, if the confirmation completion command has not been input, the process returns to S210, and the reception of the input for the synonym selection image SI is continued. On the other hand, when a confirmation completion command is input, the phrase selected in the phrase selection display 102 is determined as a word to be used for lyrics when the confirmation completion command is input.

In step S240, telop data representing the lyrics for one piece of music that is the source of the lyrics data is generated in accordance with the phrase determined in step S230. Subsequently, in S250, the two pieces of data of the partial music data generated in the previous S170 and the telop data generated in the previous S240 are transmitted to the server device 30 as generated data.
<Configuration of server device>
Here, returning to FIG. 1, the server device 30 will be described.

  The server device 30 includes an interface (hereinafter referred to as I / F) unit 31 for performing data communication with the client device 10 connected via a network, and an I / F unit 31.

  Among these, the storage device 32 is a known hard disk drive (HDD) in which a high-capacity disk and a reading device are integrally configured. The storage device 32 stores at least karaoke song data (hereinafter referred to as existing song data) prepared in advance for each song created by an artist whose business is creating music and playing music.

The control device 35 stores a ROM 38 for storing programs and data that need to retain stored contents even when the power is turned off, and transferred data (programs) and data temporarily generated during the processing. A RAM 37 and a CPU 36 that executes processing according to programs stored in the ROM 38 and the RAM 37 are provided.
<Processing on server device>
Next, a processing procedure of karaoke music collection / delivery processing executed by the control device 35 (more precisely, the CPU 36) will be described.

Here, FIG. 4 is a flowchart showing a processing procedure of the karaoke music collection and delivery processing.
This karaoke music collection / delivery process is started when the server device 30 is activated.

  Then, when the execution of the karaoke music collection / delivery process is started, as shown in FIG. 4, first, in S310, whether or not an input completion signal (and input sentence) is received (that is, acquired) from the client device 10 or not. Determine whether. As a result of the determination, if an input completion signal (and input text) has been received, the process proceeds to S320.

  In S320, morphological analysis is performed on the input sentence received from the client device 10, and the input sentence is decomposed for each input phrase. In subsequent S330, using a well-known search method, search for a phrase (that is, a synonym) similar in meaning to each of the input phrases decomposed in S320 from a plurality of phrases stored in advance in the storage device 32. And extract. Furthermore, in S340, all the synonyms extracted for each of those input phrases are output to the client device 10, and the process proceeds to S350.

Note that if the result of determination in S310 is that an input completion signal has not been received, the process also proceeds to S350.
In S350, it is determined whether or not generation data has been acquired from the client apparatus 10. If the determination result indicates that generation data has been acquired, the process proceeds to S360.

  In S360, the additional music data prepared in advance is connected to the partial music data in the generated data before and after the period represented by the partial music data. Thereby, data representing the transition of the performance sound for the entire music is generated and completed as music data.

  However, the additional music data mentioned here is music data representing a period different from the period corresponding to the partial music data in the entire period of one music data. For example, the partial music data corresponds to so-called rust. When the transition of the performance sound in the period to be performed is represented, the additional music data represents the transition of the performance sound in the period corresponding to the so-called A melody, B melody, prelude, and interlude. Accordingly, in the present embodiment, a plurality of additional music data connected to the partial music data generated by the client device 10 are provided for each corresponding period (that is, A melody, B melody, prelude, interlude). It is prepared, and it is selected at random according to the accompaniment performance from those prepared. Then, music data is generated by adding each selected additional music data to the partial music data.

  In subsequent S370, lyric data is generated based on the telop data in the generated data. Specifically, the lyric data is generated by assigning each character constituting the telop data from the first word of the input sentence for each performance sound forming the music data generated in S360.

  In S380, in addition to the music data generated in S360 and the lyrics data generated in S370, time information indicating the time required to play and play the generated music data at a predetermined tempo. Karaoke song data is generated with the character string (identification code) newly assigned to identify the generated song data as song number data and the song name input at the client device 10 as song name data. . Further, in S380, the generated karaoke song data (hereinafter, newly created karaoke song data is referred to as created song data) is stored in the storage device 32. Thereafter, the process proceeds to S390.

Note that if the result of determination in S350 is that generation data has not been acquired from the client device 10, the process also proceeds to S390.
In S390, the client device 10 issues a public command for distributing the created song data designated by the user of the client device 10 to the karaoke system 40 from all the created song data stored in the storage device 32. It is determined whether or not it has been acquired. If the result of determination is that a public command has been acquired, the process proceeds to S400.

In S400, filter processing is executed on the song data in the created song data corresponding to the disclosure command acquired in S390 and the lyrics data in the created song data.
In this filtering process, if the object to be processed is music data, the music data in karaoke music data (hereinafter referred to as existing music data) stored in advance in the storage device 32 and the music in the created music data The degree of similarity with data (here, the higher the degree of similarity, the larger the value) is derived by a known method. If the derived similarity is equal to or greater than a predetermined value, it is determined that there is a high possibility that the music corresponding to the created music data has stolen the music corresponding to the existing music data, and a warning is issued. To emit. However, after issuing a warning in the filter process, the process proceeds to S410.

  In addition, if the object to be filtered is lyrics data, the similarity between the lyrics data in the existing song data and the lyrics data in the created song data (here, the higher the degree of similarity, the larger the value) Is derived by a known method. If the derived similarity is equal to or higher than a predetermined value, it is determined that there is a high possibility that the lyrics of the music corresponding to the created music data have plagiarized the lyrics of the music corresponding to the existing music data. And issue a warning. Note that after issuing a warning in the filter process, the process proceeds to S410.

  On the other hand, if the similarity with respect to the music data and the similarity with respect to the lyrics data are both less than the specified value, it is determined that there is a low possibility that the created music and lyrics have been plagiarized, and the process proceeds to S410.

  In S410, the created music data that has been filtered in S400 is distributed to the karaoke server 45 and stored in the storage mechanism 46 of the karaoke server 45. Then, the process returns to S310.

Note that if the result of determination in S390 is that a public command has not been acquired, processing returns to S310.
In S310, the process waits until a new input completion signal (and input text) is received.
<Operation example>
Next, an operation example of the communication karaoke system 1 of the present embodiment will be described.
