Description

  The present invention relates to a karaoke apparatus.

  DESCRIPTION OF RELATED ART In the communication karaoke system, the karaoke apparatus provided with the scoring function of a karaoke song is prevailing. Scoring of karaoke singing is performed by digitizing karaoke singing of a singer and comparing with numerical value of reference data. The scoring result is displayed for each song section during the music performance, or displayed as a total score after the music performance, using a monitor that displays the lyrics and the background image.

  Furthermore, techniques for presenting not only a score evaluation but also an evaluation comment are known. For example, Patent Document 1 discloses a karaoke apparatus capable of evaluating singing in real time during music performance and reproducing the evaluation result by voice. The evaluation comment can be reproduced with voices of various voices stored in advance in the hard disk, such as a singer's voice, a voice of an animation character, or an Osaka dialect (specification paragraph [Patent Document 1] [0093]).

Unexamined-Japanese-Patent No. 2000-122674

  By the way, when reproducing the message (evaluation comment) according to song evaluation as an audio | voice, it is desirable to be emitted in the condition where a singer etc. are easy to hear. On the other hand, since karaoke performance (accompaniment) is flowing during karaoke singing, the performance may be disturbed and it may become difficult to hear a message.

  Patent Document 1 describes that the evaluation comment is reproduced at a timing according to the comment reproduction instruction data included in the karaoke performance data. That is, execution of song evaluation is instructed for each section divided by each comment reproduction instruction data, and voice output of a song evaluation result is instructed. The comment reproduction instruction data is arranged, for example, at a position at which each phrase in the music or each chorus is switched (specification paragraph of Patent Document 1 [0027]).

  However, in this case, for each of a large number of karaoke performance data, a plurality of comment reproduction instruction data must be set in advance at a position where the user can easily hear the message, which is cumbersome.

  In addition, Patent Document 1 also describes that the user performs the song evaluation and instructs the reproduction of the evaluation comment each time the user performs a predetermined operation using a remote control or the like (the specification paragraph of Patent Document 1 [0086]). .

  However, in this case, the singer can not concentrate on singing because it is necessary to execute the evaluation and the instruction to reproduce the evaluation comment during the singing. In addition, since the singer usually does not know the position where the message is easy to hear in the music, it is difficult to give an instruction to reproduce the evaluation comment or the like in consideration of the situation of the karaoke performance.

  Furthermore, Patent Document 1 describes a configuration for automatically reducing the volume of karaoke performance when an evaluation comment is reproduced (specification paragraph of Patent Document 1 [0095]). In this case, even if the karaoke performance is performed at a large volume, the evaluation comment is not missed.

  However, lowering the volume of the entire karaoke performance prior to listening to the evaluation comment is a fall at the end of the year, and there is a problem that the interest of karaoke singing is cut off.

  An object of the present invention is to provide a karaoke apparatus which enables a singer to easily grasp the contents of a message when voice output of a message according to a song evaluation.

  In order to solve the above-mentioned problems, a karaoke apparatus according to claim 1 is a karaoke apparatus for voice-outputting a message according to a scoring result of a singing voice signal obtained by performing singing of music in accordance with karaoke performance.

  The control unit 11 includes a CPU 11a and a memory 11b. The CPU 11a realizes various control functions by executing an operation program stored in the memory 11b. The memory 11 b is a storage device that stores a program to be executed by the CPU 11 a and temporarily stores various information when the program is executed.

  The communication unit 12 provides an interface for connecting the karaoke body 10 to a communication line via a router (not shown).

  The storage unit 13 is a large-capacity storage device for storing various data, and is, for example, a hard disk drive. In the present embodiment, the storage unit 13 includes a music data storage unit 13a, a message storage unit 13b, a video data storage unit 13c, and an audio data storage unit 13d.

  The music data storage unit 13a stores a plurality of music data. The music data is data used when a karaoke performance or the like is performed by the karaoke apparatus 1. When the karaoke apparatus 1 plays music based on music data, the singer can sing karaoke. The music data includes MIDI data, lyrics data, reference data and the like. In each music, there is a "song section" which is a section in which the lyrics for the singer to sing are set.

  The MIDI data is performance data for automatically playing the sound source (sound source unit 14) of the electronic musical instrument, and is constituted by time-series note information (note-on information, note-off information). The note information is constituted by various commands for controlling, for example, timing of sound generation and muffling, pressure of a key, pitch of sound, reproduction pitch and the like. Also, note information is set to a channel of each part of an instrument (for example, a drum set, a guitar, a bass guitar) included in the music. Here, in a part of an instrument in which a plurality of instruments are integrated as in a drum set, each instrument (bass drum, cymbal, hi-hat, etc. and variations thereof) map to different note numbers of one channel. The tone signal is generated by the note-on information of the corresponding pitch.

  The lyric data is character string data for displaying the lyric telop in the karaoke music on the display device 30. The lyric data is preset for each music. The reference data is data used as a reference when scoring a karaoke song by the user, and is constituted by time-series pitch information representing vocal pitches. The reference data is set for each singing section.

  The music data used in the karaoke apparatus 1 according to the present embodiment may not be stored in the music data storage unit 13a, but may be data acquired directly from a server (not shown).

  The message storage unit 13 b stores different messages in association with each of the plurality of scoring results. FIG. 3 shows an example of table data in which a plurality of scoring results are associated with messages (message IDs). In this example, the playback time is associated with each message. The “reproduction time” is the time required from the start to the end of the reproduction of the message.

  The video data storage unit 13 c is an area for storing video data such as a background image and a character displayed on the display device 30 at the time of karaoke performance.

  The voice data storage unit 13 d stores voice data representing the contents of the message stored in the message storage unit 13 b in voice. For example, the voice data storage unit 13d stores the message ID and voice data of the message in association with each other (see FIG. 4). The message stored in the message storage unit 13b and the voice data stored in the voice data storage unit 13d can be associated by giving the same message ID. Moreover, the message of this embodiment is wording adapted to the image of each character so as not to be uncomfortable even when used in the “character scoring mode” described later.

  The sound source unit 14 generates musical tone signals of a plurality of musical instruments for performing a karaoke performance based on the control of the control unit 11 and outputs the musical tone signals to the sound processing unit 15 to perform automatic performance. The sound source unit 14 is, for example, a MIDI sound source. The MIDI sound source generates a musical tone signal based on music data (note information of MIDI data). Further, the sound source unit 14 according to the present embodiment filters the note-on information corresponding to a part of the instruments among the note-on information of a plurality of musical instruments based on the control of the sound source control unit 400 (described later) Is mentioned later).

  The sound processing unit 15 controls the performance of the karaoke music and processes the audio signal input through the microphone 40 based on the control of the control unit 11. The sound processing unit 15 includes a mixer and an amplifier (both not shown). The mixer mixes the tone signal generated by the sound source unit 14 and the sound signal output from the microphone 40 at an appropriate ratio and outputs the mixed signal to the amplifier. The amplifier amplifies the mixing signal from the mixer and outputs it to the speaker 20 as a sound emission signal. As a result, from the speaker 20, the karaoke performance sound based on the sound emission signal and the singing voice from the microphone 40 are emitted. Also, the sound processing unit 15 according to the present embodiment emits a predetermined message based on the control of the sound output control unit 300 (described later).

  The display processing unit 16 performs processing related to various displays on the display device 30 based on the control of the control unit 11. For example, the display processing unit 16 controls the display device 30 to display a video in which the lyrics telop is superimposed on the background video during the karaoke performance.

Do. Control unit 11 detects an operation signal from operation unit 17 and executes a corresponding process.

(Software configuration)
FIG. 5 is a view showing an example of the software configuration of the karaoke body 10. As shown in FIG. The karaoke body 10 includes a scoring unit 100, a message selection unit 200, an audio output control unit 300, and a sound source control unit 400.

  The scoring unit 100, the message selection unit 200, the voice output control unit 300, and the sound source control unit 400 are realized by the CPU 11a of the control unit 11 executing an operation program stored in the memory 11b.

  The scoring unit 100 calculates a scoring result for each of the singing segments, for the music having a plurality of singing segments. A well-known method can be used for calculation of a scoring result. For example, when the singer performs singing in a certain singing section, the scoring unit 100 acquires a singing voice signal based on the singing. Then, the scoring unit 100 reads out the reference data corresponding to the song section from the music data storage unit 13a, and compares the acquired singing voice signal with the reference data to calculate a scoring result based on the pitch. The scoring result is calculated, for example, as score information in the range of 0 to 100 points. In addition, the scoring unit 100 may calculate not only the scoring result based on the pitch but also the comprehensive evaluation combining the volume and timing (rhythm) of the singing, and the evaluation result of the singing technique as the scoring result.

  The message selection unit 200 selects a predetermined message according to the scoring result calculated by the scoring unit 100. Specifically, the message selection unit 200 refers to the table data of the message storage unit 13b, and reads a message corresponding to the marking result of the marking unit 100 as a predetermined message.

  The voice output control unit 300 controls the sound processing unit 15 to perform voice output of the selected predetermined message at a predetermined timing corresponding to the singing section for which the scoring result is calculated.

  Specifically, the audio output control unit 300 reads out the audio data corresponding to the predetermined message ID from the audio data storage unit 13 d and transmits the audio data to the sound processing unit 15. The sound processing unit 15 causes the speaker 20 to emit a message corresponding to the sound data at a predetermined timing based on the control of the sound output control unit 300.

  The predetermined timing can be arbitrarily set as long as the scoring of the predetermined singing section is completed. For example, when the scoring is performed on a part of the singing segment, the sound processing unit 15 releases a message from the next beat of the scored segment based on the control of the audio output control unit 300. You can make it sound. Alternatively, when the scoring is performed after the singing of a certain singing section is completed, the sound processing unit 15 emits a message from the next singing section of the singing section to which the scoring is performed based on the control of the audio output control unit 300. You can make it sound.

  As described above, the “voice output control unit 300”, the “sound processing unit 15”, and the “speaker 20” constitute a “message output unit” that performs voice output of a predetermined message at a predetermined timing. When voice output is performed, it is also possible to use text data instead of using voice data recorded in advance. In this case, the voice data storage unit 13d stores text data and a message ID in association with each other. Then, the sound processing unit 15 performs speech synthesis based on text data corresponding to a predetermined message, and emits predetermined message content.

  The sound source control unit 400 controls the sound source unit 14 so as not to generate tone signals of some of the plurality of musical instruments while voice output of a predetermined message is performed.

  In order to make it easy to listen to a predetermined message, karaoke performance is an obstacle. Here, in the karaoke performance, since the performance sounds such as cymbals and hi-hats affect over the entire frequency band and the sound generation time also lasts, the voice message is easily masked. That is, when a performance sound such as a cymbal or hi-hat exists, it becomes more difficult to listen to the voice message. Therefore, while the sound output of the message is being performed, the sound source control unit 400 controls the sound source unit 14 so that the performance sound of these instruments is not emitted.

  Specifically, the sound source control unit 400 detects the timing at which the voice output of the predetermined message is performed, and during the reproduction time associated with the message, a part of the musical instruments (symbal And instructs the sound source unit 14 to interrupt the generation of the tone signal of the "hi-hat" or the "hi-hat". The sound source unit 14 filters the note-on information of the corresponding instrument based on the instruction, and interrupts the generation of the musical tone signal. On the other hand, the sound source unit 14 generates musical tones based on the note-on information for musical instruments other than the musical instruments for which the generation control of the musical tone signal is instructed by the sound source control unit 400 (for example, bass drum of drum set, guitar, bass guitar). Generate a signal. The generated tone signal is transmitted to the sound processing unit 15. The sound processing unit 15 emits a karaoke performance sound (a performance sound having no sound of a part of the musical instrument existing in the original music) based on the musical tone signal.

  Note that while the sound source control unit 400 reads sound data corresponding to a predetermined message from the sound data storage unit 13d, the sound source unit 14 is configured not to generate musical tone signals of some of a plurality of musical instruments. May be controlled. By adopting such a configuration, it is not necessary to store the reproduction time in association with each message in the message storage unit 13b. Therefore, the data stored in the message storage unit 13b can be simplified.

  Alternatively, the sound source control unit 400 may control the sound source unit 14 so as to generate only the musical tone signal of the bass instrument among the musical tone signals of the plurality of musical instruments.

  The bass instrument is an instrument that mainly plays the rhythm of the music as bass, such as a bass drum of a drum set and a bass guitar. The sound of a bass instrument is included in all general music, and since it is a bass, it is less likely to interfere with messages. Therefore, by emitting the karaoke performance sound (Karaoke performance sound excluding the middle high frequency tone signal) based on the musical tone signal of only the bass instrument, the user can more easily listen to the message. In a concert or the like, when a singer performs member introductions, greetings or the like during music (so-called MC), in many cases, it is performed in accordance with the performance of only a bass instrument. That is, by adopting the configuration in which only the musical tone signal of the low-pitched musical instrument is generated as described above, the atmosphere of the MC in a concert or the like can be reproduced.

  Specifically, the sound source control unit 400 detects the timing of audio output of a predetermined message, and only the tone signal of a bass instrument (bass drum or bass guitar) during the reproduction time associated with the message. The sound source unit 14 is instructed to generate. Based on the instruction, the sound source unit 14 filters note-on information other than the bass musical instrument, and interrupts the generation of the musical tone signal. On the other hand, the sound source unit 14 generates a musical tone signal based on the note-on information of a bass instrument (bass drum, bass guitar). When there are a plurality of low-pitched musical instruments, the sound source control unit 400 may control the sound source unit 14 so as to generate only at least one musical tone signal (for example, only a bass drum).

  Of the musical tone signals of a plurality of musical instruments, it can be set in advance, via the remote control device 50, which musical instrument's musical tone signal is to be interrupted or which musical instrument's musical tone signal is to be generated. .

== About the operation of the karaoke apparatus 1 ==
Next, a specific example of the operation of the karaoke apparatus 1 according to the present embodiment will be described with reference to FIGS. 6 and 7. FIG. 6 is a flowchart showing an operation example of the karaoke apparatus 1. FIG. 7 is a musical score showing a part of a nursery rhyme song "Fuji no yama" (songs: Sugaya small wave). The following example describes an example of interrupting generation of cymbal and hi-hat tone signals.

  The singer selects the music of "Mt. Fuji" via the remote control device 50 and sings (selection of music / singing. Step 10).

  The scoring unit 100 is the first song section, 87.5% of the song of the 8 bars of the beginning "Don't forget the head of the head", ie 7 When the singing of "Miroshiro" of the bar is finished, 85 points are calculated as the scoring result of the singing section (calculation of the scoring result. Step 11). Scoring may be performed when a certain degree (for example, about 80% to 90%) of singing is finished in a certain singing section as in this example, or it is performed when all singing in a certain singing section is finished. May be In the present invention, “calculating the scoring result for each singing section” also includes the case where the scoring result is obtained based on part of the singing in a certain singing section.

  The message selection unit 200 refers to the table data (see FIG. 3) stored in the message storage unit 13b, and selects the message M03 corresponding to the scoring result of 85 points (message selection: step 12).

  Here, the reproduction time of the message M03 is 2,100 msec. Further, as shown in the score of FIG. 8, the BPM of this music is 80, and the length of one beat is 750 msec. Therefore, the number of beats required to reproduce the message M03 is three. Therefore, the voice output control unit 300 controls the sound processing unit 15 to voice-output the message M03 in the last three beats (the second beat to the fourth beat of the eighth measure) in the first song section. That is, the audio output control unit 300 controls the sound processing unit 15 to start audio output of the message M03 with the second beat of the eighth measure at a predetermined timing (determination of the predetermined timing: step 13).

  Under the control of the sound source control unit 400, the sound source unit 14 performs the karaoke performance from the timing determined in step 13 to the end of the sound output of the message M03 (while the sound output of the predetermined message is performed). Interrupt generation of the cymbal and hi-hat tone signals among the tone signals of a plurality of instruments for performing (step 14). During this time, the sound source unit 14 generates musical tone signals of musical instruments other than the cymbal and hi-hat based on the control of the sound source control unit 400 and outputs the musical tone signals to the sound processing unit 15.

  Under the control of the audio output control unit 300, the audio processing unit 15 performs audio output of the message M03 via the speaker 20 at a predetermined timing determined in step 13. In addition, the sound processing unit 15 emits the karaoke performance sound from the speaker 20 based on the musical tone signals of the instruments other than the cymbal and the high hat during the voice output of the message M03 (message and emission of the karaoke performance sound. Step 15). .

  In this example, scoring of the song is finished at the 7th bar. Therefore, the timing of voice output of the message M03 in step 13 may be from the first beat of the eighth measure. In this case, the audio output control unit 300 can adjust the reproduction speed of the message and control the sound processing unit 15 so that the reproduction of the message M03 is performed in one bar (four beats).

  As described above, according to the karaoke apparatus 1 according to the present embodiment, the singer can easily hear by interrupting the generation of the musical tone signal of a part of the musical instrument while the voice output of the predetermined message is performed. A voice message can be output according to the song evaluation in the situation. Thus, the singer can easily grasp the contents of the message.

  In the above-mentioned example, although the example which performs voice output of a message to a singing section was described, it is not restricted to this. The song includes a singing section and a "non-singing section" which is a section in which no lyrics are set. The non-singing section corresponds to the interval from the end of a certain singing section to the start of the next singing section. Here, it is also possible to set a non-singing section between a singing section which has been scored as a predetermined timing and the next singing section. In this case, the message output unit performs voice output of the message in the non-singing section. That is, since the singing by the singer and the message do not overlap, the message can be more easily heard.

  In addition, it is also possible to use the "character scoring mode" when the singer sings. The character scoring mode is a mode that the karaoke apparatus 1 has. When the character scoring mode is selected, the display processing unit 16 (control unit 11) causes the display device 30 to display the character together with the background image and the lyrics at the time of singing, and changes the display mode of the character in accordance with the progress of the music. By installing such a mode, the karaoke apparatus 1 can give the singer a higher preference.

  In such a mode, the display processing unit 16 (control unit 11) can also perform control to change the display mode of the character in accordance with the timing of voice output of the message. For example, when the content of the message is "praise", the display processing unit 16 displays an animation that the character is pleased with. Further, by changing the expression of the character in accordance with the sound emission of the message, it is possible to give a visual effect as if the message is emitted as the speech of the character. In such a case, the singer can visually grasp the outline of the message.

Second Embodiment
A karaoke apparatus 1 according to a second embodiment will be described with reference to FIG. In the present embodiment, an example regarding the timing of outputting a selected message by voice will be described. A detailed description of the same configuration as that of the first embodiment will be omitted.

  FIG. 8 shows an example of audio data stored in the audio data storage unit 13d. In the present embodiment, one message (voice data) is composed of a plurality of parts. The "part" is an area in which the content of the message is divided into word units.

  In the present embodiment, the audio output control unit 300 performs audio output by synchronizing each of the parts constituting the selected message with the timing of the beat in the karaoke performance.

  For example, the message M03 selected in the example of FIG. 6 is composed of three parts of the message M03-01 to the message M03-03 in the present embodiment. In this case, the audio output control unit 300 performs the audio output of the message M03-01 at the timing of the second beat of the eighth measure, and the audio output of the message M03-02 at the timing of the third beat of the eighth measure, The sound processing unit 15 is controlled to output the sound of the message M03-03 at the timing of the fourth beat of the eighth measure. The sound processing unit 15 outputs the sound of the message M03-01 via the speaker 20 at the second beat of the eighth measure based on the control of the audio output control unit 300, and the speaker 20 at the third beat of the eighth measure. The voice output of the message M03-02 is performed via the above, and the voice output of the message M03-03 is performed via the speaker 20 at the fourth beat of the eighth measure.

  As described above, the message is reproduced like a lap by sequentially outputting the parts constituting the message in synchronization with the timing of the beat in the karaoke performance. That is, it is possible to provide a new way of enjoying when playing back a message.

  The number of portions is preferably determined so that the reproduction is completed within one bar of the music (in the above example, four bars per one beat or less). The length of each portion is preferably a length that can be reproduced within 500 msec, which is the length of one beat of a standard tempo (BPM = 120).

  The above embodiments are presented as examples and do not limit the scope of the invention. In addition, the above configurations can be implemented in combination as appropriate, and various omissions, replacements, and changes can be made without departing from the scope of the invention. Those embodiments and the variations thereof are included in the invention described in the claims and the equivalents thereof as well as included in the scope and the gist of the invention.
