  In this kind of karaoke apparatus, the time difference between the sound generation timing and the time when the sound is uttered with respect to the sound generation timing (hereinafter referred to as the sounding timing) is detected, and the lyrics are displayed based on the detected time difference. Some control color change timing (hereinafter referred to as change timing) (see Patent Document 1).

  That is, in the karaoke apparatus described in Patent Document 1, if the utterance timing is delayed with respect to the pronunciation timing, the change timing is advanced, and if the utterance timing is advanced with respect to the pronunciation timing, the change timing is delayed.

JP 2005-173256 A

  When singing using the karaoke device described in Patent Document 1 as described above, the singer needs to visually recognize the display of the lyrics of the music while listening to the reference melody and to match the utterance timing with the pronunciation timing. .

  However, for a singer who is not good at singing, when the song sings, there is a time difference between the pronunciation timing and the utterance timing. It is difficult to match the utterance timing to the pronunciation timing while performing both listening to the voice.

That is, in the karaoke apparatus described in Patent Document 1, it is difficult for a singer who is not good at singing to make the utterance timing coincide with the pronunciation timing.
Therefore, an object of the present invention is to provide a singing assistance device and a program that can easily match the utterance timing with the pronunciation timing even if the singer is a poor singer.

The singing assistance device of the present invention made to achieve the above object includes performance means, time derivation means, special sound setting means, object specifying means, and emphasis control means.
In the singing auxiliary device of the present invention, the musical score of the music, the sound generation timing for outputting each constituent sound constituting the melody to be sung, and the output for outputting the specific sound simulating the instrument sound of at least one kind of instrument According to the music data for which the timing is defined, the performance means plays the music and, based on the voice input during the performance of the music on the performance means, the sound generation timing corresponding to the constituent sound output during the performance The time deriving means derives a time difference indicating a time difference between the utterance timings at which the utterance is started with respect to the specific sound.

  If the derived deviation time is equal to or longer than a prescribed time that is a prescribed time length, the special sound setting means is a special sound that is a constituent sound that is output at least after a specific timing corresponding to the deviation time. A sound is set, and the target specifying means is an output timing within a special time defined in advance as a period that can be regarded as the same timing as the sound generation timing of the special component sound from the sound generation timing of each special component sound that is set The target instrument sound that is a sound is specified, and the emphasis control means emphasizes and outputs the target instrument sound specified by the target specifying means at the sounding timing of the special component sound corresponding to the target instrument sound. The emphasis control is performed to control as follows.

  According to the singing assistance device of the present invention, the target instrument sound is emphasized and output at the sound generation timing of the special component sound, so that the sound generation timing of the special component sound can be heard only without making the lyrics of the music visible. Use it to make the singer recognize.

  As a result, compared to the karaoke device described in Patent Document 1, the information necessary for recognizing the sound generation timing of the special component sound is reduced from two of visual information and auditory information to one of auditory information, Even a singer who is not good at singing can easily sing with the utterance timing matched with the sound generation timing of the constituent sounds.

  As described in claim 2, the emphasis control means in the singing assistance device according to the present invention sets the volume at which the target instrument sound is output as the deviation time is longer, and the sound generation timing of the specially configured sound corresponding to the target instrument sound. It is also possible to execute increasing as the emphasis control.

  According to the singing auxiliary device of the present invention, since the volume of the target instrument sound increases as the deviation time increases, it is possible to make a singer who is poor in singing more reliably recognize the sound generation timing of the special component sound. it can.

By the way, usually, the longer the time difference between the specific timing and the utterance timing, the more the singer is poor at singing.
For this reason, the special sound setting means in the singing assistance device of the present invention may set a larger number of component sounds as the special component sounds as the shift time is longer. According to such a singing assistance device of the present invention, a singer who is poor in singing can be uttered so that the utterance timing matches the more pronunciation timings.

  Furthermore, the object specifying means in the singing assistance device according to the present invention, as described in claim 4, when there is no specific sound that is output timing within special time from the sound generation timing of the special component sound, The specific sound added to may be used as the target instrument sound.

  According to such a singing auxiliary device of the present invention, since the target instrument sound is emphasized and reliably output at the sound generation timing of all the special component sounds, the singers recognize the sound generation timings of all the special component sounds. Can be made. As a result, the music can be made easier to sing.

Moreover, in the singing assistance apparatus of the present invention, it is desirable that the musical instrument corresponding to the target musical instrument sound is a musical instrument that engraves a rhythm in music.
The reason why the musical instrument sound of such a musical instrument is the target musical instrument sound is that the singer can easily recognize the sound generation timing of the special component sound.

The present invention may be a program for causing a computer to function as a singing assistance device.
When the present invention is configured as such a program, the program of the present invention is input according to the music data according to the music data and the performance procedure for performing the music and the performance of the music. Based on the received voice, a time derivation procedure for deriving a time difference representing the time difference of the utterance timing of the constituent sound with respect to the specific timing, and a special constituent sound is set if the derived time difference is equal to or longer than a specified time From the special sound setting procedure and the sound generation timing of each special component sound that has been set, the target specifying procedure for specifying the target instrument sound that is the specific sound that will be output within the special time, and the specified target instrument sound And an emphasis control procedure for executing emphasis control for controlling the sound to be emphasized and output at the sounding timing of the specially configured sound corresponding to the target musical instrument sound. There is a need to be executed.

<About the structure of music data>
Next, the music data is data represented by a well-known MIDI standard, and is prepared for each music produced in advance. The music data includes identification data that is data for distinguishing music corresponding to the music data (hereinafter referred to as corresponding music), musical score data that is data representing the music score of the corresponding music, and data representing the lyrics of the corresponding music. And at least lyric data.

Among these, the musical score data is prepared for each type of musical instrument played with the corresponding music piece, and notes representing the contents of the sound output from the sound module 15 are arranged along the time axis. Hereinafter, the sound output from the tone generator module 15 is referred to as a specific sound NO according to the notes of the score data. Specifically speaking, each score data is a period (so-called note length) during which the sound source module 15 outputs each specific sound NO _k. Further, the pitch (so-called note-on number) NN _{k of} each specific sound NO _k and parameters (so-called attack, velocity, decay, release level, etc.) indicating the strength of the specific sound NO _k are included.

Among these, the period for outputting the specific sound NO _k is the sound generation timing (so-called note-on timing) ON _k indicating the time from the start of the performance of the corresponding music until the sound module 15 starts outputting the specific sound NO _k. , And an end timing (so-called note-off timing) OFF _k representing the time from the start of the performance of the corresponding music until the output of the specific sound NO _k is ended.

In the present embodiment, the notes of specific sounds (hereinafter referred to as constituent sounds) NOg _k constituting the melody (hereinafter referred to as reference melody) to be sung in the corresponding music are listed among a plurality of score data. The score data is called a guide melody.

Further, in the present embodiment, the subscript k is an index number that indicates what number the specific sound NO _k is output from the start of the performance of the corresponding music piece.
<Configuration of control unit>
Next, the control unit 20 stores the ROM 21 that stores processing programs and data that need to retain stored contents even when the power is turned off, the RAM 22 that temporarily stores processing programs and data, and the ROM 21 and the RAM 22 that store them. A known computer having at least a CPU 23 that executes each process (various operations) according to the processed program is configured.

  In the present embodiment, as a processing program executed by the control unit 20, the corresponding music is played based on the music data, and the timing at which the singer utters from the singing start timing of the played corresponding music (hereinafter referred to as the song). If the utterance timing is misaligned, a specific sound NO that satisfies the specific condition is output in advance. Hereinafter, processing executed by this processing program is referred to as karaoke performance processing.

<About the contents of karaoke performance processing>
Next, the karaoke performance process which the control part 20 of the karaoke apparatus 10 performs is demonstrated.
This karaoke performance process starts when an activation command for activating this karaoke performance process is input via the input receiving unit 11.

Then, as shown in FIG. 2, when the karaoke performance process is started, the music data corresponding to the music specified by the information input via the input receiving unit 11, that is, the lyrics data and each simulated musical instrument. Is obtained (S110). Based on each score data included in the acquired music data, the tone generator module 15 is made to output the constituent sounds NOg _k and the specific sounds NO _k (ie, musical sounds) defined in each score data. At the same time, based on the lyric data included in the music data to be displayed on the display unit 12 the lyrics corresponding to the configuration sound NOG _k outputted from the sound source module 15 (S120).

A sound uttered by the singer (hereinafter referred to as a singing sound) is input to the constituent sound NOg _k output from the sound source module 15 via the voice input unit 13, and the input singing sound is amplified. And output from the audio output unit 14. Then, when the performance of the corresponding music progresses as time progresses, the tone generator module 15 outputs the component sound NOg _k having the sound generation timing ONg _k that matches the singing start timing described above. In the present embodiment, the first syllable in one phrase constituting the lyrics is defined as the singing start timing.

When such a configuration sound NOG _k is output from the sound source module 15, sound generation timing of the component tones NOG _k (hereinafter, specific and timing) Ong _k, and utterance timings of singing sound with respect to the component notes NOG _k In contrast, a time difference between the specific timing ONg _k and the vocalization timing of the singing sound (hereinafter, referred to as a deviation time) is derived (S130). Specifically, the utterance timing of the singing sound in the present embodiment is a timing at which the signal level of the singing sound input via the voice input unit 13 changes from less than a prescribed level to a prescribed level or more. .

Subsequently, if the deviation time derived in S130 is equal to or longer than a prescribed time which is a prescribed time length (S140: YES), instrument sound enhancement processing is executed (S150). This instrument sound emphasizing process is performed at least for a specific sound NO in which a sound generation timing ON that can be regarded as the same as the sound generation timing ONd of the component sound (hereinafter referred to as a special component sound) NOd output after the specific timing ONg _k in the corresponding music piece. The target instrument sound NOt is controlled so that the target instrument sound NOt is output from the sound source module 15 with the specific sound NO (hereinafter referred to as the target instrument sound NOt) satisfying the above-described specific conditions. It is processing to do. Thereafter, the process returns to S120.

On the other hand, if the time difference is less than the specified time (S140: NO), the process returns to S120 without executing the instrument sound enhancement process.
As described above, when the process returns to S120, the tone generator module 15 is caused to output new musical sounds (that is, the constituent sound NOg and the specific sound NO) for the corresponding music.

  Then, the steps from S120 to S150 are repeatedly executed until the music data acquired in S110 ends or an end command for ending the karaoke performance process is input via the input receiving unit 11.

<Processing details of instrument sound enhancement processing>
Next, the instrument sound enhancement process started in S150 of the karaoke performance process will be described.
As shown in FIG. 3, when the instrument sound enhancement process is started, the deviation time derived in S130 is a preset time (however, the preset time> the prescribed time). It is determined whether or not this is the case (S510).

A result of the determination in this S510, if the shift time is the set time or more (S510: YES), all the component notes NOg output after a certain timing Ong _k, is set as a special component sounds NOD (S520). On the other hand, if the deviation time is less than the set time as a result of the determination in S510 (S510: NO), among the constituent sounds NOg output after the specific timing ONg _{k, the} sound generation timing ONg _k that matches the singing start timing. Is set as a special component sound NOd (S530). That is, the longer the time difference is, the more the singers determine that they cannot sing with the utterance timing matched with the singing start timing, and the number of special component sounds NOd is increased.

Subsequently, an index number N indicating what number the special component sound NOd is output from the specific timing ONg _k is set to an initial value (1 in the present embodiment) (S540). The instrument rhythmic corresponding music (e.g., a drum) of the specific sound NOR _L corresponding to, sound generation timing of the special configuration sound NOD _N (hereinafter, a special timing) from OND _N, the same timing as the particular timing OND _N The presence / absence of the specific sound NOr _L that becomes the sound generation timing ONr _L within a special time A (50 [msec] in the present embodiment) defined in advance as a period that can be regarded is determined (S550). In the present embodiment, the symbol r means that the specific sound NOr corresponds to a musical instrument in which the rhythm is engraved, and the subscript L is the order from which the specific sound NOr starts playing the corresponding music. It means an index number that indicates whether it is output.

As a result of the determination in S550, if there is a specific sound NOr _L having the sound generation timing ONr _L within the special time A from the special timing ONd _N (S550: YES), the specific sound NOr _L is set as the target instrument sound NOt _N. Setting is made (S560). On the other hand, if there is no specific sound NOr _L that becomes the sound generation timing ONr _L within the special time A from the special timing ONd _N (S550: NO), the specific sound NOm corresponding to the instrument (for example, bass) playing the melody of the corresponding music piece. of _M, it determines the presence or absence of specific sound NOM _M as the sound generation timing onm _M from a special timing OND _N within the special time a (S570). In the present embodiment, the symbol m means that the specific sound NOm corresponds to a musical instrument that plays a melody, and the subscript M indicates the number of the specific sound NOm from the start of performance of the corresponding music. This means an index number that indicates whether the data is output to.

As a result of the determination in S570, if the specific sound NOm _M having the sound generation timing ONm _M exists within the special time A from the special timing ONd _N (S570: YES), the specific sound NOm _M is used as the target instrument sound. It is set as NOt _N (S580). On the other hand, as a result of the determination in S570, if there is no specific sound NOm _M that becomes the sound generation timing ONm _M within the special time A from the special timing ONd _N (S570: NO), an instrument that engraves the rhythm of the corresponding music (for example, drum) the specific sound NOr corresponding targeting instrument sound NOt _N, newly added to (S590).

Note that the sound generation timing ONt _N of the target musical instrument sound NOt _N newly added in S590 of the present embodiment is the special timing ONd _{N so} that the target musical instrument sound NOt _N is output at the special timing ONd _N. Set to

In this way, the target instrument sound NOt _N corresponding to the particular constituent notes NOD _N is set, as the target instrument sound NOt _N are emphasized and output, setting the parameters of the target instrument sound NOt _N (S600). Specifically, in S600 of the present embodiment, if the target instrument sound NOt _N is the specific sound NOr _L corresponding to the instrument that engraves the rhythm of the corresponding music, the longer the deviation time derived in S130, The velocity of the specific sound NOr _L is set so that the volume of the target musical instrument sound NOt _N is increased. On the other hand, if the target instrument sound NOt _N is the specific sound NOm _M corresponding to the instrument that plays the melody of the corresponding music piece, the volume of the target instrument sound NOt _N increases with the special timing ONd _N as the deviation time increases. Thus, the attack, decay, and velocity of the target musical instrument sound NOt _N are set. At the same time, the release level is lowered so that the overall volume during the sounding period of the target musical instrument sound NOt _N is lowered. Since the period during which the specific sound NOr _L is output is shorter than the special component sound NOd _N , only the velocity is set in the target musical instrument sound NOt _N set based on the specific sound NOr _L. The

Subsequently, it is determined whether or not the index number N of the special component sound NOd is greater than or equal to the maximum value Nmax (S610). As a result of the determination in S610, if the index number N of the special component sound NOd has not reached the maximum value Nmax (S610: NO), the index number N of the special component sound NOd is incremented by 1, and the process proceeds to S550. Return. On the other hand, when the index number N of the special component sound NOd reaches the maximum value Nmax (S610: YES), the instrument sound enhancement process is terminated and the process returns to the karaoke performance process. That, along with all of the target instrument sound NOt _N corresponding to the particular component notes NOd is set, so that their target instrument sound NOt _N are emphasized and output, the parameters of the target instrument sound NOt _N is set Then, the instrument sound enhancement process is terminated.

That is, in the musical instrument sound emphasizing process according to the present embodiment, if there is a specific sound NOr _L that becomes the sounding timing ONr _L within the special time A from the special timing ONd _N in the musical score data for the rhythmic musical instrument, it is shown in FIG. As described above, all the specific sounds NOr _L having the sound generation timing ONr _L within the special time A from the special timing ONd _N are set as the target musical instrument sound NOt _N. On the other hand, in the musical score data for instruments rhythmic, if there is no specific sound NOR _L as the sound generation timing ONr _L from a special timing OND _N within the special time A, as shown in FIG. 5, the special time from a special timing OND _N Within A, a specific sound NOr having a pronunciation timing ONr _L is newly added to update the musical score data.

Then, in the karaoke performance process executed after the instrument sound enhancement process is executed, when the performance of the corresponding music advances with the progress of time, the target instrument sound NOt _N is output at a louder volume than the other specific sounds NO. The

[Effect of the embodiment]
As described above, according to the karaoke device 10 of the present embodiment, since the special timing OND _N to target instrument sound NOt _N are emphasized and output, the special timing OND _N, using the auditory only, singer Can be recognized.

In particular, according to the karaoke device 10 of the present embodiment, in all the special timing OND _N, since the volume of the target instrument sound is increased, it is possible to recognize the singer special timing OND _N more reliably. Moreover, in the karaoke apparatus 10, since the target instrument sound NOt _N is set centering on the specific sound NOr _L corresponding to the instrument that engraves the rhythm of the corresponding music, it is easy for the singer to recognize the rhythm of the corresponding music. as a result, it is possible to easily recognize the special timing OND _N.

That is, the information for recognizing the special timing ONd _N is reduced from the visual information and the auditory information to one of the auditory information as compared with the conventional karaoke apparatus (for example, described in Patent Document 1). The corresponding music can be made easier to sing. As a result, by using the karaoke system 10 of the present embodiment, singing is even an unskilled singer, may be singing readily to match the utterance timing special timing OND _N.

In particular, in the karaoke apparatus 10 of the present embodiment, the longer the deviation time, the greater the number of component sounds NOg _k set as the special component sound NOd _N , and the volume of the target instrument sound NOt _N increases. For this reason, if the number of specific sounds NO that are emphasized and output (that is, the target musical instrument sound NOt _N ) decreases as the corresponding music progresses along the time axis, the utterance timing is made to coincide with the special timing ONd _N. The singers themselves can recognize that they are able to speak.

  Moreover, in the karaoke performance process of the said embodiment, when the corresponding music is played, the time for starting the execution of the instrument sound emphasizing process is greater than the specified time when the corresponding music is started to be played. Although the timing is used, the timing for starting the execution of the instrument sound enhancement process is not limited to this. For example, after a corresponding piece of music is played, if the average deviation time with respect to all the singing start timings of the corresponding piece is equal to or longer than a specified time, the next piece to be played via the input reception unit 11 The start time of the performance of the corresponding music designated as may be set as the timing for starting the execution of the instrument sound enhancement process.

  In this case, the method for deriving the deviation time is, for example, a trajectory in which the pitch of the singing sound has changed (hereinafter referred to as singing pitch change), and a pitch in which the pitch of the constituent sound in the reference melody of the corresponding music has changed. It may be contrasted with (hereinafter referred to as reference pitch transition). That is, the singing pitch transition is shifted back and forth along the time axis with respect to the reference pitch transition, and the singing pitch transition is the closest approximation to the reference pitch transition (the degree of approximation is maximized). , It may be derived as a deviation time. At this time, as a method of correcting the position on the time axis so that the singing pitch transition and the reference pitch transition are approximated, for example, a method described in JP-A-2005-107330 may be used. It is done.

In the karaoke performance process of the above embodiments, by increasing the volume of the target instrument sound NOt _N, but highlights the target instrument sound NOt _N, the method emphasizing target instrument sound NOt _N is limited thereto It is not a thing. For example, by suppressing the volume of the specific sound NO other than the specific sound NO which is set as the target instrument sound NOt _N, it may be emphasized target instrument sound NOt _N.

In the karaoke performance processing of the above embodiment, the condition for inserting a new specific sound NO as the target musical instrument sound NOt _{N is set} as “the specific sound of the rhythm instrument whose sounding timing is ON within the special time A from the special component sound NOd _N ”. “NOr” and “specific musical instrument specific sound NOm” are both absent (ie, S550: NO and S570: NO). The condition for inserting a new specific sound NO as the target musical instrument sound NOt _{N is} as follows: The present invention is not limited to this, and there may be a case where only the “specific sound NOr of the rhythm instrument” whose sound generation timing is ON within the special time A from the special component sound NOd _N does not exist. In other words, S570 and S580 may be omitted in the instrument sound enhancement process.

  In the karaoke apparatus 10 of the above embodiment, the music data is stored in the storage unit 16 in advance. However, in the karaoke apparatus 10, the music data may be acquired from the outside via a public communication network. That is, the karaoke apparatus 10 of the above embodiment may be configured as a so-called communication karaoke apparatus.

  Although the singing assistance apparatus in the said embodiment was comprised as the karaoke apparatus 10, the singing assistance apparatus of this invention is not restricted to the karaoke apparatus 10, For example, the input reception part 11 mentioned above, the display part 12, and The information processing device (so-called personal computer) including the voice input unit 13, the voice output unit 14, the sound source module 15, the storage unit 16, and the control unit 20 may be used.

If the deviation time derived in the time derivation procedure is equal to or longer than a prescribed time that is a prescribed time length, at least a special constituent sound that is a constituent sound output after a specific timing corresponding to the deviation time. Special sound setting procedure to be set,
It is a specific sound that becomes the output timing within a special time defined in advance as a period that can be regarded as the same timing as the sound generation timing of the special component sound from the sound generation timing of each special component sound set in the special sound setting procedure A target identification procedure for identifying the target instrument sound;
An emphasis control procedure for performing emphasis control for controlling the target instrument sound identified by the target identification procedure to be emphasized and output at the sounding timing of the specially configured sound corresponding to the target instrument sound. A program characterized by being executed.
