Description

  The present invention relates to a karaoke system that allows a singer to determine a singing range that can be sung when singing karaoke music.

  Conventionally, when singing karaoke music with a karaoke device, the range of the playback sound of the karaoke music can be arbitrarily set with the operation panel of the karaoke device main body or the key control of the remote control so that it is suitable for the singer's own singing range for each karaoke song I am trying to set it. Since the setting of the sound range by this key control returns to the standard state when the singer finishes singing, it must be set for each song, which is a troublesome operation for the singer. In addition, since the singer sets the sound range with a general sense, it cannot be determined whether the setting is suitable for himself until the karaoke music is actually sung.

In order to deal with such problems, there has been proposed a technique in which a singer determines the highest sound and the lowest sound that can be generated by uttering according to a guide sound before singing (see Patent Document 1). In addition, during the singing of the selected karaoke song, the singing voice input from the microphone is input to the pitch detection circuit, and the highest pitch and the lowest pitch in the input voice signal are detected from the start to the end of the karaoke song performance. It has been proposed that the detection result is displayed on the monitor as a note or key code along with the staff notation to visualize the singer's range, and to determine whether the range of the selected karaoke music is suitable for himself ( Patent Document 2).
JP-A-9-212185 JP 2002-73058 A

  In the technique disclosed in Patent Document 1, the singer's range is determined based on the result of uttering according to the guidance sound, and the singer is not determined based on the result of actually singing the song. The original singing range of the singer cannot always be determined. Also, since the singer sequentially utters following the scale starting from the reference sound and rising by one note (or semitone), the feeling of mechanical processing remains, which is preferable in karaoke where emphasis is placed on entertainment. It is not a thing. On the other hand, in the technique disclosed in Patent Document 2, a note or a key code is displayed on a monitor so that a singer can recognize his / her own range, but not all singers have music knowledge. In addition, it is extremely difficult to select a karaoke piece suitable for its own range from notes or key codes, and it cannot be a simple method.

  Therefore, in the present invention, the singer sings as if he / she actually enjoyed singing karaoke music, so that the singing sound range can be determined smoothly, and the list of karaoke music suitable for singing or unsuitable karaoke music based on the determination result This makes it possible to easily select a karaoke piece that can be easily sung.

  The present invention has been made in order to solve the above-mentioned problems. The karaoke apparatus according to claim 1 of the present invention is provided with a singing range determination system, and selects karaoke pieces having different predetermined ranges and medley classified by range. A song is created, and the singer sings this medley song by range, so that the proper range of the singer can be determined. That is, the reference range of any karaoke song and the singing range of the singer by comparing the singing range of the singer, the singing range measuring means for determining the singing range of the singer, and the range set in advance with reference to the range recorded in the karaoke song The music range management means for registering the karaoke music corresponding to the classification in the management table, and a part of a predetermined number of karaoke songs with different sound ranges selected from the karaoke music registered in the management table of the music range management means are connected. In addition, a medley music creation means for each range that creates a medley song by range, and a singer sings based on the medley song by range, and the singing result is determined by the singing range measurement means for each medley song by range. Based on the singing means for determining the singing range of the singer and the determination result of the singing range for each medley musical piece, the singer can Wherein the proper range determining means for determining a singing can range, to become comprises a to.

  The invention according to claim 2 is the karaoke apparatus according to claim 1, wherein the medley music composition by means of sound range further includes music selection means, and the music selection means is recorded by the singer in the management table. By selecting selected karaoke songs, a part of a predetermined number of different karaoke songs can be connected to create a medley song by sound range.

  According to the karaoke apparatus of the first aspect of the present invention, it is possible to determine an appropriate sound range that the singer originally has while enjoying singing karaoke music. In other words, singing by singers of singing range medley music that is not found in ordinary medley music is now possible, so unlike conventional judgment by guided sound, singing karaoke music is appropriate while enjoying medley A singing range can be determined. Therefore, a list of karaoke songs suitable for the singing of the singer can be easily created based on the determination result, and the selection of the karaoke songs becomes easy. On the other hand, since it is possible to easily create a list of karaoke songs based on the determination result that is unsuitable for singing, this can be used as a list for exercise to serve as a reference for challenging poor karaoke songs.

  And according to the karaoke apparatus of Claim 2 of this invention, when producing a song range medley, it becomes possible for a singer himself to select the song area from which a range differs, and to produce a song range medley music. . That is, since the karaoke music which a singer knows and favorite karaoke music can be selected and a singing sound range medley music can be created, the singer's original appropriate sound range can be determined while enjoying the singing of the music more.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the configuration of a karaoke apparatus 1 according to an embodiment of the present invention as a performance terminal of a communication karaoke system. In the figure, a central control unit 11 is a microcomputer including a CPU, a RAM, and a ROM. The central control unit 11 exchanges signals with components connected thereto via a control / data bus 50 to control the entire system. Take control.

  The central control unit 11 can perform data communication by controlling the communication control unit 12 and connecting to the karaoke host device 100 via the information communication network N. The karaoke host device 100 has a database in which management data, statistical data and the like are stored as well as karaoke music data, and data is exchanged with a karaoke performance terminal. The music data distributed from the karaoke host device 100 is stored in the hard disk device 13 and is read based on the control of the central control unit 11.

  The music data is the music generation data that is the origin of the karaoke accompaniment music described in MIDI (Musical Instrument Digital Interface) format, and the lyrics that are displayed in synchronization with the performance of the karaoke music and the attributes of the characters (display position, display color) Lyric drawing data describing display / erase timing, etc.). When the central control unit 11 receives the ID input of the requested music from the remote control transmitter 14, the remote control receiving unit 15 and the operation panel 16 via the operation control unit 17, the input order is associated with the ID and stored in the RAM. Register a music performance reservation.

  Then, the music data of the corresponding karaoke music is taken out from the hard disk device 13 in accordance with the reservation order, and the MIDI data in the music data is transferred to the synthesizer 18, and the synthesizer 18 controls the built-in sound source according to the MIDI data and plays the karaoke accompaniment music. Generate. The performance signal of karaoke accompaniment music output by the synthesizer 18 is mixed with the singing voice signal from the microphone 20 by the mixing amplifier 19 and output, and the speaker system 21 is driven to obtain an acoustic output.

  On the other hand, in synchronization with the karaoke accompaniment music generation process, a bitmap image to be a lyric image is developed in the video RAM 22. The video control unit 23 performs a process of superimposing the bitmap image on the background video output from the video disk device 24 and outputs the video to the display 25.

  FIG. 2 is a block diagram showing a specific configuration of the singing sound range measuring unit 26, which is configured by a dedicated DSP (Digital Signal Processor). As shown in the figure, the D / A converter 26a for sampling the singing voice signal input from the microphone 20 and the sampling data output from the D / A converter 26a are analyzed in real time to determine the vocal pitch of the singer. A singing pitch acquisition unit 26b for acquisition, and a pitch comparison unit 26c that compares the acquired utterance pitch with a reference pitch to be uttered in the accompaniment music currently being performed, which is given by the note number, and outputs the difference as error data Is built in as a functional element. In this case, each musical tone pitch of data corresponding to the main melody in MIDI data is adopted as the reference pitch.

  FIG. 3 illustrates a method for specifying the singing range from the error data generated by the range measuring unit 26. As shown in FIG. 3, the horizontal axis represents the reference pitch for each key code, and this reference pitch is used as the reference pitch. On the other hand, the singing pitch obtained from the singing voice signal of the singer is compared and the error is plotted. Since the same reference pitch appears multiple times during the performance of one karaoke piece, the average value of the singing pitch error with respect to the same reference pitch is plotted. As a result, the key code range at the time when the singing pitch exceeds the reference pitch can be determined as the singing range of the singer. In the case of the drawing, the key code G4 to the key code F3 indicate the singer's singing range.

  Next, a method of extracting a part of a plurality of different karaoke pieces and connecting them to determine a singing range will be described below. As is well known, the range of karaoke music is different for each song. For example, there are karaoke songs with a wide range from high to low. The singer's singing range cannot be accurately determined with only one karaoke piece.

  Therefore, in the present invention, a part of a plurality of different karaoke pieces is selected and connected to create a medley piece by range that can accurately determine the singer's singing range based on karaoke pieces having different pitches. In this case, it is desirable that each medley musical piece is in a different musical range. For this reason, a management table for categorizing and registering stored karaoke musical pieces for each musical range is provided to enable quick selection of karaoke musical pieces. I did it.

  FIG. 4 shows a registration state in the management table, and the sound ranges are roughly classified into a high region, a medium region, a low region, and a wide region having a wide sound region width. Then, range information (highest tone and lowest tone) is extracted from the music data, and it is determined to which of the classified sound ranges the karaoke music corresponds. Each karaoke piece determined in this way has its music ID registered in the designated part of each range as shown in the figure, and for example, it is possible to determine which range corresponds to the end number.

  In this way, when karaoke music is classified and registered for each sound range and a medley music by sound range is created, all the movements of the selected karaoke music are not connected, but a part of the music is selected. For example, in the case where the singing part is completed by No. 1, No. 2, No. 3, such as a popular song, the same melody is usually repeated in each movement, so only the No. 1 chorus needs to be connected.

  In addition, when a plurality of choruses are connected and redundant, it is possible to extract so-called rust parts and connect them to create a medley musical composition by range. In addition, when creating medley songs by range, for example, enter age, gender, music genre, etc. to set specific conditions, or limit high, mid, low, and wide songs in the management table It is also possible to extract one song at a time. It is also possible to display a list of high, middle, reduced, and wide karaoke songs registered in the management table on the display 25, and a singer can arbitrarily select from this list. In the present embodiment, specific information is input when creating a medley musical composition by range.

  Next, the flow of determination processing by the karaoke device 1 of the present invention configured as described above, according to the program of the singing range of the singer and the generation of the medley musical composition for each range will be described. As shown in FIG. 5, at the beginning of the selection of the medley music, the specific condition as described above is input (Sa1). When this input is completed (Sa2), the central control unit 11 selects only one song from each sound range (high range, mid range, low range, wide range) corresponding to the input condition from the management table.

  The selected karaoke music pieces are arranged and connected in the central control unit 11 (Sa4), temporarily stored in the RAM and reserved for performance of the medley music (Sa5). FIG. 6 shows an example of the completed state of the medley list of the medley musical piece by sound range. Intro Int. Followed by the 1st medley section (high range), 2nd medley section (middle range), 3rd medley section (low range), 4th medley section (wide area), ending End. Is arranged. IS is an intro start mark, IE is an intro end mark, CS is a chorus start mark, CE is a chorus end mark, ES is an ending start mark, and EE is an ending end mark.

  Thus, a medley musical composition for each range is created, and an instruction to start the medley performance is given by the singer operating the remote control transmitter 14 (Sa6). Each medley is performed sequentially from the performance of the performance, and when the final 4th medley section confirms the end of the performance (Sa7), the ending End. Play to end all playing. In each medley section, a natural connection between songs can be obtained by performing a process such as crossfade that gradually decreases the volume of the previous song and gradually increases the volume of the next song.

  Since the above processing flow connects the medley sections of a plurality of karaoke songs, it takes a relatively long performance time, but a highly accurate result can be expected for the determination of the singing range of the singer. On the other hand, when it is intended to shorten the performance time, it is only necessary to extract a characteristic portion (rust portion) in the medley section and complete the medley musical composition according to the range as described above. FIG. 7 shows a medley list of the first medley section to the fourth medley section in which the chorus parts MG1 to MG4 are specified by the chorus start mark SS and the chorus end mark SE in the chorus, and the chorus parts MG1 to MG4 are connected. FIG. 8 shows the medley musical composition for each musical range completed together.

  Next, the flow of the determination process by the program of the singing range of the singer who performs the medley musical composition according to the range created as described above and sings along with this will be described with reference to FIG. When the processing of step Sa6 in FIG. 5 is performed and the medley music to be played is recognized (Sb1), the reference pitch of the medley section is set in the pitch comparison unit 26c of the singing range measuring unit 26 from the music ID of the medley music ( Sb2).

  Then, each medley section is played sequentially, the singer's singing pitch is acquired by the singing pitch acquisition unit 26b, and error data as shown in FIG. 3 is obtained from the pitch comparison unit 26c (Sb3). FIG. 10 schematically shows an example in which the reference sound range of each medley section and the singer's singing sound range are compared from the error data thus obtained. In this case, the reference sound range of the 1st medley section in the high range is the key codes E3 to G4, whereas the singing range is the key codes F3 to G4, and it is difficult for the singer to sing the key code F3 or higher. I understand that.

  It can be seen that the 2nd medley section is a karaoke piece in the middle region having a lower key than the first medley section, and the reference sound range is key codes G3 to A4, and the singer's singing range corresponds sufficiently. It can be seen that the 3rd medley section is a karaoke piece of music with a lower key that is lower than the 2nd medley section, and that the reference sound range is key codes C4 to D5, so that the singer can cope.

  However, the singer in this case has a possibility of singing a lower karaoke piece, and this cannot be determined only in the 1st to 3rd medley section. The 4th medley section is designed to cope with such a problem, and karaoke music with a wide range from high to low is selected. Since the reference sound range of the 4th medley section is the key code D # 3 to E5 and the singer's singing sound range is the key code F3 to D # 5, it can be understood that the singing of this karaoke music is quite difficult. .

  Thus, when the performance of each medley section is completed (Sb4), the key code of the singer's highest sound and lowest sound is determined and stored for each medley section (Sb5). When the performance of all the medley sections is finished (Sb6), the singers' accurate singing range is determined as the key codes F3 to D # 5 from the highest and lowest key codes of each medley section. Thus, it is determined that the 2nd medley section, the 3rd medley section, and the karaoke music corresponding to this range are easily sung by the singer (Sb7).

  When the singer designates the music selection from the remote control transmitter 14 or the operation panel 16 based on the above results, when the specific conditions such as age, gender, music genre are set, the management table described above based on the specific conditions A predetermined number of karaoke music pieces whose sound ranges correspond to or approximate the sound ranges of the 2nd medley section and the 3rd medley section are extracted in advance and displayed on the display 25 as a list. And a singer can select a preferable karaoke music from the displayed music list immediately. In addition, since it is possible to create a list of karaoke songs that are determined to be difficult for the singer to sing, it is possible to try to challenge the difficult songs with reference to this.

  In this way, karaoke music suitable for the singer can be presented immediately based on the measurement results of the singing range, so compared to the case where the results of the singing range are displayed as notes or key codes as in the past. This makes it possible to select karaoke songs quickly and accurately. Further, since the determination of the singing sound range is performed while enjoying the medley music and singing, an effect unique to the present invention can be obtained, such as an improvement in amusement.
