  By the way, when outputting the music for karaoke performance by the karaoke device, that is, when outputting the music that displays the lyric character video in parallel with the output, the voice information is not necessarily input from the voice input device. For example, if a user who was sitting at a companion at a snack or pub and stopped singing and started talking to the companion, or challenged a song that was not used to singing in a karaoke box, etc. If it becomes impossible to sing in the middle of the trial, and the next music is not reserved, it is conceivable that the output of the music is continued without inputting the voice information from the voice input device. In such a case, there is a possibility that a song that no one sings will continue to flow at a volume different from that of the BGM, which may not match the atmosphere of the place. However, as in the conventional technique, a technique for setting the volume for each content such as karaoke music or a movie cannot solve such a problem. Such a problem has been newly found in the process of continuing the intensive research by the present inventors with the intention of improving the usability of the karaoke apparatus.

Volume setting means for setting each volume, and voice input determination means for determining the presence or absence of input of voice information from the voice input device, the volume setting means using the voice input determination means, the voice input device While it is determined that there is no input of audio information from, the first output volume of the music is output even when the music that outputs the lyrics character image is displayed in parallel with the output. The amount is characterized in that setting the volume based on different second volume.

  If it does in this way, as the output volume of the music, the first volume is output at the time of the output of the music that displays the lyrics character video in parallel with the output, and the output at the time of the music that does not display the lyrics character video in parallel with the output. 2 and a sound input determining means for determining the presence / absence of input of sound information from the sound input device, the sound volume setting means using the sound input determining means While it is determined that there is no input of audio information from the input device, the first volume is set as the output volume of the music even when the music that outputs the lyrics character image is displayed in parallel with the output. Set the volume based on the second volume different from the above, so that no one sings a song that continues to flow at a volume different from that of BGM. The suitably suppressed. That is, it is possible to provide a karaoke apparatus that suitably sets the output volume of music according to the atmosphere of the place.

  Here, preferably, at the time of outputting the music for displaying the lyric character video in parallel with the output, the voice input determining means, for a section where a vocal part does not exist among a plurality of performance sections in the music, No judgment is made. In this way, although it is a performance section of a song premised on singing, it is suitably suppressed that an inappropriate determination is extended and a volume change is performed in a portion where a vocal part does not exist and singing is not predicated. it can.

  Preferably, the recording apparatus further includes volume storage means for storing the second volume set at the time of outputting the music that does not display the lyric character video in parallel with the output, and the volume setting means is in parallel with the output. Based on the second volume stored in the volume storage unit, the volume while the audio input determination unit determines that no audio information is input at the time of output of the music for displaying the lyrics character image. To decide. In this way, according to the BGM output volume set in the past, the output volume of each piece of music can be set to a more finely suitable value.

  Preferably, the volume setting means is configured to output a plurality of second volumes stored in the volume storage means at the time of outputting a song that displays a lyric character video in parallel with the output. Based on the plurality of second sound volumes based on a predetermined relationship, the sound volume is calculated while the sound input determining means determines that no sound information is input. In this way, according to the BGM output volume set in the past, the output volume of each piece of music can be set to a more finely suitable value.

  Preferably, the sound volume setting means determines that voice information has been input by the voice input determination means after the output is started at the time of output of the music for displaying the lyrics character video in parallel with the output. In the meantime, the first volume is set as the output volume of the music, and after the voice input determination means determines that voice information has been input, the control based on the determination result is executed. To do. In this way, an inappropriate volume setting is performed between the start of the output of the music that is not originally input by the audio input device until the user starts singing, and the output music is a karaoke performance song. Or BGM music can be suitably suppressed.

In addition, the voice input determination unit 66 preferably performs the determination at the time of outputting a song that is determined to be a song that displays a lyrics character image in parallel with the output by the song type determination unit 62, while The determination is not performed when the music type determining means 62 outputs the music that is determined not to be a music that displays the lyrics character image in parallel with the output.

  The volume setting means 68 sets the output volume (volume) of the music when the performance control means 60 outputs the music. Specifically, the output volume of the music is changed based on the determination result by the music type determination means 62. That is, basically, the first volume (karaoke performance volume) β is output as the output volume of the music that has been determined by the music type determination means 62 to be the music that displays the lyrics text image in parallel with the output. The second volume (BGM volume) α is set as the output volume of the song that is determined to be a song that does not display the lyrics character image. Here, preferably, the first volume β is larger than the second volume α. The volume setting means 68 preferably sets the first volume β and the second volume α in accordance with a setting of a volume knob on the operation panel 24 or the like. For example, the volume corresponding to the setting of the volume knob is set as the first volume β, and the volume corresponding to the setting of the volume knob is multiplied by a predetermined correction factor (for example, about 0.6). Is set as the second volume α. Preferably, the operation panel 24 may be configured such that the first sound volume β and the second sound volume α can be individually set. In this aspect, the sound volume setting The means 68 sets the first volume β and the second volume α according to the setting of the volume knob on the operation panel 24 or the like.

  The sound volume setting unit 68 outputs the sound from the microphone 34 by the sound input determination unit 66 when outputting the music that is determined to be a song that displays the lyrics character image in parallel with the output by the music type determination unit 62. While it is determined that there is no input of information, the output volume of the music is different from the first volume β as the output volume of the music even when outputting the music that displays the lyrics character image in parallel with the output. The volume βb based on the volume α of 2 is set. FIG. 3 is a diagram for explaining an example of the volume setting by the volume setting means 68. As shown in FIG. 3, the volume setting means 68 is a music waiting BGM that is a song that does not display the lyric character video in parallel with the output, that is, as the volume of the music that is played in synchronization with the output of the inter-song data. The second volume α is set. Further, in the performance section of the song A, which is a song for which the lyrics character image is displayed in parallel with the output, the first sound volume β (= βa) is basically set, but the audio information from the microphone 34 is set. The first volume β is changed according to whether or not there is an input. That is, the first volume βa is set in the performance section where the voice information is input from the microphone 34, and the volume βb is different from the first volume βa in the performance section where the voice information is not input from the microphone 34. Set each. Here, preferably, the volume βb set in the performance section in which no audio information is input from the microphone 34 is smaller than the first volume βa. Further, the volume βb set in the performance section in which no audio information is input from the microphone 34 may be equal to the second volume α, but preferably as described in detail below. It is calculated based on the second sound volume α.

  The volume storage means 70 shown in FIG. 2 stores the second volume α set at the time of outputting the music that does not display the lyrics character image in parallel with the output. For example, the actual output level output as the second sound volume α at the time of outputting the music that does not display the lyric character video in parallel with the output is stored in the sound volume table 52 in the RAM 16 or the like. Further, in the aspect in which a volume obtained by multiplying a volume corresponding to the setting of the volume knob by a predetermined correction rate is set as the second volume α, the correction rate may be stored in the volume table 52. . FIG. 4 is a diagram showing an example of the volume table 52. As shown in FIG. 4, the volume table 52 includes, for example, dates and times d1 to d10 to be recorded, identification information (music selection number) of corresponding music (all music A in FIG. 4), The BGM value at the date and time when the music was sung, that is, the second sound volumes α1 to α10 are stored in association with each other. In other words, the volume storage means 70 preferably uses the second volume α set at the time of outputting the music that does not display the lyrics character image concurrently with the output as the corresponding music identification information (music selection number). And store it in association with. For example, the second volume α set immediately before or after the output of the corresponding music is stored in the volume table 52 in association with the identification information of the music. Further, preferably, the second volume α set at the date and time when the corresponding music is output is stored in the volume table 52 in association with the identification information of the music.

  The sound volume setting means 68 is preferably configured to output the sound volume βb while the sound input determination means 66 determines that no sound information is being input when outputting a song that displays lyrics character images in parallel with the output. Is determined based on the second volume α stored in the volume table 52 by the volume storage means 70. Preferably, when the music based on the predetermined music data is output, the sound volume βb while the audio input determination means 66 determines that no audio information is input is associated with the music data (music selection number). And determined based on the second volume α stored in the volume table 52. Preferably, the second sound volume α stored in the sound volume table 52 is set as the sound volume βb while the sound input determination means 66 determines that no sound information is input.

  In addition, the volume setting means 68 preferably has a plurality of the second volume α stored in the volume table 52 at the time of outputting a song that displays a lyric character image in parallel with the output. Calculates the sound volume βb while the sound input determination means 66 determines that no sound information is input based on the plurality of second sound volumes α from a predetermined relationship. For example, as shown in FIG. 4, when the second volume α1 to α10 at the time of output of the song A corresponding to the song A is stored in the volume table 52, the second volume α1 to α10 is stored. The average is set as the volume βb during which it is determined by the voice input determination means 66 that no voice information is input. That is, it is determined from the second sound volumes α1, α2,..., Αn stored in the sound volume table 52 by the sound input determining means 66 that there is no input of sound information according to the following equation (1). The sound volume βb is calculated.

  βb = (α1 + α2 +... + αn) / n (1)

  Preferably, the voice input determination unit 66 preferably performs the determination for a section in which a vocal part does not exist among a plurality of performance sections in the music at the time of outputting the music that displays the lyric character video in parallel with the output. Not performed. That is, when the vocal part determination unit 64 determines that the part currently being played is a part corresponding to a vocal part, the voice input determination unit 66 inputs voice information from the microphone 34. If the vocal part determination means 64 determines that the currently played part is not a part corresponding to the vocal part, the song part that displays the lyric text image along with the output is determined. Even at the time of output, determination by the voice input determination means 66 is not performed.

  The sound volume setting means 68 is preferably configured to output the sound input determination for a section in which a vocal part does not exist among a plurality of performance sections in the music at the time of outputting the music that displays the lyrics character video in parallel with the output. Even when it is determined by the means 66 that there is no input of audio information from the microphone 34, the first sound volume β (= βa) is set. That is, it is determined by the vocal part determination means 64 that the part currently being played is a part corresponding to a vocal part, and the voice input determination means 66 does not input voice information from the microphone 34. If it is determined, the volume βb based on the second volume α different from the first volume β (= βa) is set as the output volume of the music, but the vocal part determination means 64 currently sets the volume βb. If it is determined that the part being played is not a part corresponding to the vocal part, the output volume of the music is not changed regardless of the determination result by the sound input determination means 66.

  In addition, the volume setting means 68 is preferably adapted to input the first voice information by the voice input determination means 66 after the output is started at the time of outputting the music for displaying the lyrics character video in parallel with the output. Until it is determined that there is a sound, the first sound volume β (= βa) is set as the output sound volume of the music, and the sound input determination means 66 determines that the first sound information has been input. Thereafter, the control based on the determination result is executed. That is, setting of the sound volume βb based on the determination result by the voice input determination unit 66 is started on the condition that the voice input determination unit 66 determines that the first voice information has been input.

  FIG. 5 is a time chart for explaining an example of the volume setting by the volume setting means 68 according to the presence or absence of the vocal part. In the example shown in FIG. 5, the performance output of the music is started at time t1, and the performance output of the section corresponding to the prelude (intro) in the music is performed until time t2. Between this time t1 and time t2, there is no input of audio information from the microphone 34, but it is from the start of music output until it is determined that there is input of the first audio information, and Since this is a section corresponding to a prelude that does not correspond to a vocal part, the first volume β (= βa) is set as the output volume of the music. Next, a portion corresponding to the vocal part of the music is output from time t2 to time t3. Since audio information is input from the microphone 34 from time t2 to time t3, the first volume βa is set as the output volume of the music. Next, during the period from time t3 to time t4, performance output corresponding to the music interlude is performed. During this period from time t3 to time t4, there is no input of audio information from the microphone 34, but since this is a section corresponding to an interlude that does not correspond to a vocal part, the first volume βa is set as the output volume of the music Is done. Next, a portion corresponding to the vocal part of the music is output again from time t4. After this time t4, there is no input of audio information from the microphone 34, and since it is a performance section corresponding to a vocal part, the volume βb based on the second volume α is set as the output volume of the music.

  FIG. 6 is a flowchart for explaining a main part of the volume setting control by the CPU 12 of the karaoke apparatus 10 and is repeatedly executed at a predetermined cycle.

  First, in step (hereinafter, step is omitted) S1, it is determined whether or not there is a song stored in the reserved song table 50 as a reserved song. That is, it is determined whether or not it is the output start timing of the music that displays the lyrics character video in parallel with the output. If the determination in S1 is negative, the second volume α is set as the output volume of the music in S2, and the output of the inter-music data and the reproduction of the music data associated therewith is performed. The determination is executed again. However, if the determination in S1 is affirmative, in S3, the second volume α set at that time is associated with the music selection number of the music related to the output start, and Stored in the volume table 52. Next, in S4, music data corresponding to the music stored as the reserved music in the reserved music table 50 is read from the music database 44, and performance output based on the music data is started.

  Next, in S5, the first volume β (= βa) is set as the output volume of the music. Next, in S6, it is determined whether or not the performance of the part corresponding to the vocal part has been started. While the determination of S6 is denied, the process waits by repeating the determination of S6. When the determination of S6 is affirmed, it is determined in S7 whether or not there has been a voice input from the microphone 34. To be judged. While the determination of S7 is denied, the process waits by repeating the determination of S7. However, when the determination of S7 is affirmed, the input level relating to the voice input from the microphone 34 is determined in S8. Judgment is started.

  Next, in S9, it is determined whether or not the current performance location is a portion corresponding to the vocal part. While the determination of S9 is denied, the process waits by repeating the determination of S9. However, when the determination of S9 is affirmed, in S10, it corresponds to the voice information input from the microphone 34. It is determined whether or not the input level is greater than a predetermined threshold. If the determination in S10 is affirmative, the processing from S12 onward is executed. If the determination in S10 is negative, the output volume of the music is different from the first volume β in S11. After the sound volume βb based on the second sound volume α is calculated and set, in S12, it is determined whether or not the music performance is ended, for example, the music is played to the end. If the determination in S12 is negative, the processing from S9 onward is executed again. If the determination in S12 is positive, the routine is terminated.

  In the above control, S4 and S12 are the operation of the performance control means 60, S1 is the operation of the music type determination means 62, S6 and S9 are the operations of the vocal part determination means 64, and S7 and S10 are the sounds. S2, S5, and S11 correspond to the operation of the volume setting unit 68, and S3 corresponds to the operation of the volume storage unit 70, respectively.

  Thus, according to the present embodiment, as the output volume of the music, the first volume β is displayed at the time of output of the music for displaying the lyrics character video along with the output, and the lyrics character video is displayed along with the output. The sound volume determination means 68 (S2, S5, and S11) for setting the second sound volume α at the time of outputting the music that is not to be output, and the sound input determination for determining whether sound information is input from the microphone 34 that is a sound input device Means 66 (S7 and S10), and the sound volume setting means 68 is in parallel with the output while the sound input determining means 66 determines that no sound information is input from the microphone 34. Even at the time of outputting a song displaying a lyric character image, the volume βb based on the second volume α different from the first volume β is set as the output volume of the song. Therefore, it is possible to suitably prevent the music that no one sings from being sung on a premise and continue to flow at a volume different from that of the BGM. That is, it is possible to provide the karaoke apparatus 10 that suitably sets the output volume of the music according to the atmosphere of the place.

  Further, the voice input determination means 66 does not perform the determination on a section where a vocal part does not exist among a plurality of performance sections in the music at the time of outputting the music that displays the lyrics character image in parallel with the output. Therefore, although it is a performance section of a song that is premised on singing, it is possible to suitably suppress a change in volume due to inappropriate determination in a portion that does not have vocal parts and does not presuppose singing .

  In addition, a volume storage means 70 (S3) for storing the second volume α set at the time of outputting the music that does not display the lyrics character video in parallel with the output is provided, and the volume setting means 68 is in parallel with the output. Then, at the time of outputting the music to display the lyric character image, the volume βb while the voice input determining means 66 determines that no voice information is input is stored in the volume table 52 by the volume storage means 70. Since the determination is made based on the second volume α, the output volume of each song can be set to a more fine and suitable value according to the BGM output volume set in the past.

  In addition, the volume setting means 68 includes a plurality of the second volume α stored in the volume table 52 by the volume storage means 70 at the time of outputting a song that displays a lyric character image in parallel with the output. In this case, the sound volume βb is calculated based on the plurality of second sound volumes α based on the predetermined relationship, while the sound input determining means 66 determines that no sound information is input. Therefore, according to the BGM output volume set in the past, the output volume of each song can be set to a finer and more suitable value.

  The sound volume setting means 68 determines that the sound input determination means 66 has input sound information after the output is started when outputting the music that displays the lyrics character video in parallel with the output. Until the first sound volume β is set as the output sound volume of the music, and after the sound input determination means 66 determines that sound information has been input, the control based on the determination result is executed. Therefore, an inappropriate volume setting is performed between the start of the output of the music that is not input by the microphone 34 until the user starts singing, and the output music is a karaoke performance song. Or BGM music can be suitably suppressed.

  The preferred embodiments of the present invention have been described in detail with reference to the drawings. However, the present invention is not limited to these embodiments, and may be implemented in other modes.

  For example, in the above-described embodiment, a song that is output based on song data (karaoke data) stored in the song database 44 as a song that displays a lyric character image in parallel with the output is displayed along with the output. The music that is output based on the music data in synchronism with the output of the inter-song data as the music that does not display the character video and the music that is output based on the BGM data in the BGM mode are exemplified, but the present invention is not limited to this. In particular, various other modes are conceivable for the music that does not display the lyric text image in parallel with the output. For example, in the aspect in which the karaoke apparatus 10 displays the scene name of the past movie on the display 30 and outputs the sound, the output sound corresponds to the music that does not display the lyric character image in parallel with the output. To do. Further, when a predetermined operation related to the karaoke apparatus 10 is performed by a remote controller (not shown), when a screen related to the operation is displayed on the display 30 and predetermined music data is reproduced, the reproduced music Corresponds to the music that does not display the lyrics character image in parallel with the output.

  Further, in the above-described embodiment, the vocal part determination unit 66 sets the vocal part other than the sections corresponding to the prelude, the interlude, and the postlude when outputting the music based on the music data stored in the music database 44. While it was determined that it was a corresponding part, it was determined that the sections corresponding to the prelude, interlude, and subsequent play were not equivalent to the vocal part, but this is just an example of suitable control However, the present invention is not limited to this. For example, regarding music data for which voice information is to be input by the microphone 34 even during interlude, such as narration, rap, or scat exist in the interlude, it is determined that the interlude is a portion corresponding to the vocal part. It may be a thing.

  In the above-described embodiment, the first sound volume β is larger than the second sound volume α. However, in consideration of the situation used by the karaoke apparatus 10, the volume between the BGMs is larger. The first volume β may be smaller than the second volume α. Similarly, the volume βb set in the performance section in which no audio information is input from the microphone 34 may be larger than the first volume βa.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
