  For example, in TV commercials, only a part of music is played due to the broadcast time. Many people know (remember) the parts of such songs that are repeatedly aired, but not the other parts. Even if a karaoke user wants to sing such music, he simply listens to the accompaniment performance in an unknown section, and is uninteresting, and in some cases, the atmosphere of the place is irritated. Also, even if you want to learn an unknown section, it is difficult to understand the correspondence between the melody and the lyrics because only the melody voice and the lyrics on the screen are provided. Also, a song with a sub-melody (chorus part) that adds harmony to the main melody, a duet song, etc. cannot be established by singing alone.

  The present invention has been made to solve the problems of such a conventional karaoke apparatus. Accordingly, an object of the present invention is to provide a karaoke apparatus capable of selectively outputting a prepared voice and a control method thereof.

  An object of the present invention is to reproduce a singing voice data of a song to generate a singing voice signal, a selection means to selectively output a singing voice signal generated by the reproducing means, and an audio signal input from a microphone. And output means for outputting the singing voice signal classified by part output by the selection means, and the selection means switches between outputting or not outputting the singing voice signal based on a user instruction. This is achieved by a karaoke device.

  ADVANTAGE OF THE INVENTION According to this invention, the karaoke apparatus which can selectively output the audio | voice prepared beforehand, and its control method can be provided.

It is a figure which shows the function structural example of the karaoke apparatus which concerns on embodiment of this invention. It is a flowchart regarding operation | movement of the karaoke apparatus which concerns on embodiment.

  Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram showing a functional configuration example of a karaoke apparatus capable of implementing the present invention. The karaoke apparatus according to the present embodiment receives music data from a server accessible via a network. However, at least part of the music data may be included in the karaoke apparatus. Here, the music data is a general term for various data related to music such as accompaniment data, lyrics data, melody data, singing voice data by part, and video data. In addition, the karaoke apparatus of the present embodiment can be realized in any electronic device that can execute a karaoke application. Such electronic devices include, but are not limited to, a personal computer, a tablet terminal, and a game machine. .

  The karaoke apparatus 10 includes a main body 100, a microphone 130, a display 200, and a speaker 300. Note that at least one of the microphone 130, the display 200, and the speaker 300 may be built in the main body 100. In the present embodiment, the microphone 130 has a switch 138 for instructing on / off of the proxy song reproduction. In addition, although the structure where the microphone 130 is a wireless microphone is demonstrated here, a wired microphone may be sufficient.

  The control unit 101 has, for example, one or more programmable processors, a ROM, and a RAM, and controls the operation of each functional block of the karaoke apparatus 10 by loading the program stored in the ROM and executing it. Thus, various functions of the karaoke apparatus 10 are realized. Note that the control unit 101 may realize at least a part of control by hardware such as ASIC or ASSP. Although the control unit 101 is communicably connected to each functional block, the connection is not shown in the figure for the sake of clarity. In addition, at least a part of the functional blocks of the main body 100 may be realized by a programmable processor included in the control unit 101 executing a program.

  In the main body 100, a network interface (I / F) 102 is a communication interface with an external device such as the server 400. The network I / F 102 supports communication conforming to one or more wired and / or wireless communication standards, and includes an antenna, a connector, a transmission / reception circuit, and the like according to the standard.

  The separation unit 104 separates music data received from the server 400 for each type of data. In the present embodiment, the music data received from the server 400 can include five types of data: accompaniment data, melody data, lyrics data, part-by-part singing data, and video data. Some data may not be included. The melody data is data indicating a pitch (main melody) to be sung. The accompaniment data, melody data, and lyrics data may be in an integrated format such as MIDI (Musical Instrument Digital Interface) data.

  The part-by-part singing data is voice data in which a human voice or synthesized voice sings a song, and when the song has a plurality of song parts, independent voice data is prepared for each song part. In this embodiment, for a piece of music sung by a plurality of people, the singing part is treated as one part, the parts having sections with different singing contents are handled as separate parts, and singing data by part is prepared. Note that the singing part may be handled as a plurality of parts, and part-specific singing data for the number of singers may be prepared. In this case, the singers (voice quality) may be different in the plurality of pieces of singing data related to the singing part. It is assumed that the reproduction time of the part-by-part singing data is the same for all the parts, and silent audio data is included in the section without singing.

  The separation unit 104 outputs the singing data for each part to the audio reproduction unit 105, the accompaniment data and the melody data to the accompaniment reproduction unit 106, the lyrics data to the lyrics video generation unit 120, and the video data to the video reproduction unit 122. . Note that the separation unit 104 does not output data of a type that is not included.

  The audio reproduction unit 105 reproduces the part-specific song data and outputs the obtained analog audio signal to the audio selection unit 116.

  The accompaniment reproducing unit 106 reproduces accompaniment data, and outputs the obtained analog audio signal to the mixer 118. The accompaniment data may be data that conforms to a predetermined standard, such as MIDI (Musical Instrument Digital Interface) data.

  The microphone sound receiving unit 110 receives the singing sound signal from the sound transmitting unit of the microphone 130 and outputs the singing sound signal to the mixer 118. The SW state reception unit 112 receives a signal (state signal) indicating the state of the selection SW 138 of the microphone 130 from the state transmission unit 136 of the microphone 130 and outputs the signal to the voice selection unit 116.

  As described above, the microphone 130 has one or more selection switches (SW) 138 for selecting part-specific song data to be output to the speaker 300. The selection SW 138 is an arbitrary electronic device that can have two states, such as a pressed state and a non-pressed state, a touch state and a non-touch state, and an on state and an off state. A signal (state signal) indicating the state of the selection SW 138 is transmitted to the SW state reception unit 112 of the main body 100 through the state transmission unit 136.

  In addition, an electrical signal (singing voice signal) representing voice input to the microphone 130 is transmitted to the microphone voice receiving unit 110 of the main body 100 through the voice transmission unit 134. Here, in order to facilitate understanding, the state signal and the singing voice signal are transmitted and received separately, but one signal obtained by multiplexing the singing voice signal and the state signal is transmitted, and the main body 100 You may comprise so that a singing voice signal and a status signal may be isolate | separated.

  The audio selection unit 116 outputs one or more part-by-part singing audio signals from the audio reproduction unit 105 according to the state signal from the SW state reception unit 112, or does not output any of them. The relationship between the state of the selection SW 138 represented by the state signal and the song part to be output can be determined in advance. For example, when there are a number of selection SWs 138 equal to the number of song data or the maximum number of singing parts supported by the karaoke apparatus 10, each of the selection SW 138s is associated with one singing part, and the first state of the selection SW 138 is output (selected). The second state can be assigned to non-output (non-selection). For example, the first state may be a pressed state, a touch state, or an on state of the selection SW 138, and the second state may be a non-pressed state, a non-touch state, or an off state of the selection SW 138. Further, when the number of selection SW 138 is smaller than the maximum number of song parts supported by the music data or the karaoke apparatus 10, it is possible to correspond to a combination of song parts for outputting a combination of states of a plurality of selection SW 138.

  Of the states of the selection SW 138 indicated by the state signal, the sound selection unit 116 outputs the part-by-part singing sound signal corresponding to the selection SW 138 in the first state to the mixer 118, and the part corresponding to the selection SW 138 in the second state. The separate singing voice signal is not output to the mixer 118.

  Note that the selection SW 138 may be provided in the remote controller 140, the operation unit 128, or the like instead of being provided in the microphone 130 or separately from the microphone 130. In this case, the voice selection unit 116 controls the part-by-part singing voice signal output to the mixer 118 according to the state signal received through the control unit 101.

  The mixer 118 mixes the principal singing voice signal from the microphone voice receiving unit 110, the accompaniment voice signal from the accompaniment playback unit 106, and the part-by-part singing voice signal from the voice selection unit 116, and outputs them to the additional function unit 119. To do. The additional function unit 119 adds an acoustic effect such as an echo to the singing voice output from the mixer 118, changes the pitch, and performs scoring. These additional functions related to the singing voice can be realized by a known configuration. The functions performed by the additional function unit 119 can be set by the user through the operation unit 128, the remote controller 140, or the like. The additional function unit 119 outputs an audio signal to which an effect is added according to the setting to the speaker 300. Note that the additional function unit 119 may be configured to process the person singing voice or the proxy singing voice input to the mixer 118. For example, the speaker 300 incorporating the amplifier converts an audio signal from the additional function unit 119 (or the mixer 118) into an audible sound and outputs it. For example, by inputting a voice signal obtained by mixing a person's singing voice signal and a part-by-part singing voice signal in place of a microphone input to an existing karaoke apparatus, various additional functions of the existing karaoke apparatus are used as they are. be able to.

The remote controller 140 and the operation unit 128 are input devices for the user to input instructions to the karaoke apparatus 10 and include switches, keys, dials, and the like. Data from the remote controller 140 is received by the receiving unit 129 and notified to the control unit 101. Further, the operation of the operation unit 118 provided in the main body 100 is directly detected by the control unit 101. The control unit 101 executes an operation corresponding to the operation content of the remote controller 140 or the operation unit 128. For example, when a music reservation operation is performed with the remote controller 140 or the operation unit 128, the control unit 101 requests the server 400 to distribute music data through the network I / F 102. When the key change operation of the music being played is performed, the control unit 101 instructs the accompaniment playback unit 106 to change the playback key.
When the selection SW 138 is provided in the remote controller 140 or the operation unit 128, the control unit 101 supplies a state signal indicating the state of the selection SW 138 to the voice selection unit 116.

  The lyric video generation unit 120 generates lyric display data to be superimposed on the video based on the lyric data received from the separation unit 104 and outputs the lyric display data to the video synthesis unit 126. The video reproduction unit 122 reproduces the video data received from the separation unit 104 or the video data read from the video database 124 and outputs the video data to the video composition unit 126. For example, when the video database 124 includes video data associated with the music to be played back, the video playback unit 122 plays back the video data stored in the video database 124.

  The video synthesis unit 126 synthesizes the video data from the video playback unit 122 and the video data from the lyrics video generation unit 120 to generate display image data, and outputs the display image data to the display 200.

  The singing voice switching operation in the karaoke apparatus 10 having such a configuration will be further described with reference to the flowchart of FIG. FIG. 2 is a flowchart describing a process related to the reproduction of one piece of music, focusing on reproduction of part-by-part singing voice by the selection SW 138. The control unit 101 causes the separation unit 104 to separate the music data received through the network I / F 102 into, for example, accompaniment data, melody data, lyrics data, video data, and part-specific singing voice data. Note that the type of data to be separated may be different depending on the format of the received data.

  The separated data is stored, for example, in a buffer in the separation unit 104 until the music is played back. When it is time to start playing the music, the control unit 101 starts the supply from the separation unit 104 to the accompaniment playback unit 106, the audio playback unit 105, the lyrics video generation unit 120, and the video playback unit 122 as necessary. . Thereby, accompaniment playback by the accompaniment playback unit 106, video playback by the video playback unit 122, lyrics image generation by the lyric video generation unit 120, and playback of part-by-part singing voice data by the voice playback unit 105 are started (S201).

  The microphone sound receiving unit 110 outputs the singing sound signal received from the microphone 130 to the mixer 118. Further, the SW state reception unit 112 outputs the state signal received from the microphone 130 to the voice selection unit 116. In S <b> 203, the voice selection unit 116 outputs the part-specific singing voice signal corresponding to the selection SW 138 whose state signal indicates the first state to the mixer 118. The voice selection unit 116 also blocks the part-by-part singing voice signal corresponding to the selection SW 138 whose state signal indicates the second state and does not output it to the mixer 118.

  The voice selection unit 116 determines whether or not the state signal has changed in S205. If it is determined that the state signal has changed, the process returns to S203, and if it has not been determined, the process proceeds to S207. Accordingly, when the user changes the state of the selection SW 138 during the reproduction of the music, the part-by-part singing voice signal that is output / blocked according to the change changes.

  In step S209, the control unit 101 determines whether or not the music end condition is satisfied. If it is determined that the end condition is satisfied, the process ends. If not, the process returns to step S205. Continue. The music end condition may be, for example, that the reproduction has been completed to the end of the music, or that the end of the music has been instructed. When the end of the music is instructed, the control unit 101 also ends the music playback process. Note that the control unit 101 starts the process of reproducing the next music if there is a music reproduction reservation remaining.

  Thus, according to the present embodiment, the singing voice prepared for each singing part of the music is selectively reproduced by the karaoke apparatus 10. Therefore, even if the user remembers only a part of the music, for example, the prepared singing voice can be reproduced for the part that is not remembered. For this reason, only the accompaniment is reproduced in the section that is not remembered, and there is no feeling of awkwardness. Further, when practicing one part of a duet song, the singing timing of the other part can be practiced more effectively by causing the karaoke apparatus 10 to reproduce the singing voice of the other part.

  In the above-described embodiment, the configuration in which the part-by-part singing voice data is pre-recorded human singing voice data has been described. However, the structure which synthesize | combines a voice with the karaoke apparatus 10 may be sufficient.

  In the above-described embodiment, the part-by-part singing voice data included in the music data is reproduced for all channels, and then the voice selection unit 116 selects the part to be output. However, the singing voice data for each part may be reproduced only for the part to be output. In this case, for example, the state signal of the selection SW 138 may be supplied also to the separation unit 104 and only the part-by-part singing voice data corresponding to the part to be output may be supplied to the voice reproduction unit 105. Alternatively, for example, the state signal of the selection SW 138 may be supplied to the sound reproduction unit 105, and the sound reproduction unit 105 may be controlled so as to reproduce only the part-by-part singing sound data corresponding to the part to be output.

  In addition, the computer program for implement | achieving the operation | movement which concerns on reproduction | regeneration and output control of the song sound according to part mentioned above, and the recording medium which preserve | saved this computer program also comprise this invention.
