DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus for singing and enjoying a vocal part while playing back an accompaniment part such as a song.

[0002]

2. Description of the Related Art In recent years, a so-called karaoke system in which a vocal part is enjoyed while playing back an accompaniment part of a song or the like,
It is widely used in many countries including Japan. Karaoke equipment
For example, the performance of accompaniment parts of a plurality of songs and the superimposition of the video and lyrics suitable for each song to be displayed on the monitor screen are recorded on an optical disc, and when the song is designated, the corresponding video and lyrics are recorded on the disc. Reads the corresponding performance information and video information from above, plays back the video information on the monitor and plays back the accompaniment performance, amplifies the singing voice picked up by the microphone with the amplifier, and adds effects such as reverberation sound To play from the speaker.

[0003] Normally, the range of sounds that can be generated differs for each singer, so that in the karaoke apparatus, when the accompaniment portion is reproduced, the pitch can be adjusted slightly by adjusting the reproduction speed. In the case of this method, when the width of the pitch adjustment becomes wide, the reproduction time changes accordingly.

[0004] For a karaoke apparatus using an optical disk as described above, accompaniment data is transferred to a MIDI (Musical Instrument Digital Interface).
There is a type in which an accompaniment is re-synthesized by using a MIDI sound source at the time of reproduction in the form of information.

[0005] A schematic configuration of MIDI information will be described with reference to FIGS. 5 and 6. As shown in FIG. 5, the MIDI information is
One message is composed of 2-byte or 3-byte data in which the first bit of the first byte, that is, bit 7 starts with logical 1. The type of message is specified by the first byte, that is, the status byte. The meaning of the following two bytes of information is determined for each type of message. FIG.
In the above, note-off and note-on of message types correspond to stopping or outputting a sound, respectively. The note number of the first data byte whose status is note-off and note-on indicates the pitch. The center C in the piano is a note number 60, and the scales C-2 to G8 are assigned from 0 to 127. 88
In the case of a standard piano key, note numbers from 6 to 108 correspond to A-1 to C7. The velocity of the subsequent second data byte represents the speed at which the key is pressed, and thus corresponds to the volume of the note. The polyphonic key pressure transmits aftertouch information for controlling the pitch and size of each sounding channel according to the pressure value of the second data byte. In the program change, a timbre, that is, an instrument is specified by the program number of the first data byte.

In the case of such karaoke using MIDI, since the pitch of the sound is represented by a digital code as a note number, for example, the pitch range of the accompaniment portion is different because the singable range differs for each individual singing person. , The pitch can be easily adjusted simply by rewriting the note number, and the playback time does not change even if the pitch is adjusted.

FIG. 7 shows a conventional karaoke apparatus. In FIG. 7, reference numeral 1 denotes a music data file storing a large amount of music data in the form of MIDI information. A tune to be reproduced is selected from the tune data file 1 by inputting an operation element (not shown) attached to the karaoke apparatus. Pitch conversion means 2
Indicates that the note number in the MIDI information read from the music data file 1 is determined by the pitch specified by an operation input (not shown) attached to the karaoke apparatus, for example, 2 or 3 or the original MIDI. The information is sent to the musical sound synthesizing means 3 shifted from the note number of the information. The musical sound synthesizing means 3 synthesizes an accompaniment from the input MIDI information and sends it to the mixer 4.

The mixer 4 mixes the vocal portion sung by the performer picked up by the microphone with the output of the musical sound synthesizing means 3 and sends it to the amplifier 5, which amplifies and outputs the input signal.

[0009]

As described above, in the above-mentioned conventional example, the pitch of the accompaniment can be easily changed by the operator of the karaoke apparatus according to the range in which the player can utter each song, and the playing time can be changed. Does not change.

However, it is necessary to re-specify the pitch correction amount each time, depending on the relationship between the range in which the player can utter himself and the range present in the vocal part of the song, which is a complicated and unfamiliar song. When singing, it was also difficult to specify the amount of pitch correction in advance.

In view of the above-mentioned problems of the conventional karaoke apparatus, the present invention reproduces an accompaniment unit using the karaoke apparatus.
It is an object of the present invention to provide a karaoke apparatus in which, when singing a vocal part accordingly, the accompaniment part is optimally adjusted in pitch according to the range of the singer's voice and reproduced, so that the performance effect is significantly improved. Is what you do.

[0012]

Therefore, in the karaoke apparatus of the present invention, a first tone range judging means for extracting the highest pitch and / or the lowest pitch included in the melody of the vocal portion of the music, A second gamut judging means for extracting a singing person's highest sound and / or a lowest sound that can be uttered is compared with an output of the first gamut judging means and an output of the second judging means. The comparison means, and the comparison result by the comparison means, when the singing person has difficulty in uttering at least one of the highest pitch and / or the lowest pitch included in the melody of the vocal portion of the song, This problem is overcome by providing pitch correction means for correcting pitch information when synthesizing a music signal from the original music data.

[0013] With this configuration, the pitch of the accompaniment is automatically and optimally corrected in accordance with the range in which the singer can speak, so that the singer can enjoy karaoke more than before.

Further, in another configuration example of the present invention, a first range determining means for extracting at least one of the highest pitch and / or the lowest pitch included in the melody of the vocal portion of the music, and the voice of the singer A second range determining means for extracting at least one of a highest possible tone and a lowest possible tone;
A memory that stores the determination result of the vocal range determination unit as singing human range information together with designation information for specifying the singing person;
Singing person designating means for designating a singing person, and comparing means for calling specific singing person range information from the memory according to the output of the singing person designating means and comparing with the output result of the first range determining means. And, in the comparison result by the comparing means, when the singing person cannot perform the highest pitch and / or the lowest pitch included in the melody of the vocal portion of the music, and according to the comparison result, Since the pitch information is corrected at the time of synthesizing the music signal from the original music data, it is sufficient to register the vocal range of each member once, such as when enjoying karaoke with a plurality of friends, and the convenience is improved. More.

In still another configuration of the present invention, the singing person is provided with utterance range specifying means for inputting utterance range information for specifying both or one of the highest and lowest sounds that can be uttered. The singer who remembers the utterable range can directly specify his / her highest and lowest utterable ranges, which can further simplify registration of the utterable range.

[0016]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. The same components as those in the conventional example of FIG. 7 are denoted by the same reference numerals. First, the configuration of the block diagram of FIG. 1 will be described.

In FIG. 1, reference numeral 1 denotes a music data file storing a large amount of music data in the form of MIDI information. A tune to be reproduced is selected from the tune data file 1 by inputting an operation element (not shown) attached to the karaoke apparatus. Reference numeral 6 denotes a tone range determining means for searching for the highest tone and the lowest tone included in the vocal portion of the selected music. Numeral 7 is a mapping means for comparing the gamut of the tune output by the gamut judging means 6 with the vocal range of the singer to calculate a pitch adjustment amount at the time of tune reproduction. Reference numeral 2 denotes a pitch conversion unit that corrects the note number of the MIDI data output from the music data file in accordance with the output of the mapping unit 7 and sends the corrected MIDI data to the tone synthesis unit 3. The tone synthesizing means 3 receives the input MI.
This is means for synthesizing accompaniment from the DI information and sending it to the mixer 4. The mixer 4 mixes the vocal portion sung by the player picked up by the microphone with the output of the musical sound synthesis means 3,
The signal is sent to the amplifier 5, and the amplifier 5 is means for amplifying and outputting the input signal.

The pitch extracting means 8 is a pitch extracting means for detecting a frequency from a singing person's voice inputted from a microphone. As a method of pitch extraction, a method widely used in the field of voice processing can be used. For example, a method of detecting a zero crossing of a sound waveform and measuring a period thereof, an autocorrelation method, a cepstrum method, or the like can be used.

Reference numeral 9 denotes a tone range judging means for detecting the highest tone and the lowest tone from the output of the pitch extracting means 8, converting them to note numbers, and outputting the note numbers. The data is registered in the sound range data file 10 as voice sound range data together with the data.

Next, the operation of the embodiment of the present invention shown in FIG. 1 will be described with reference to FIG. 2, FIG. 3, and FIG. FIG.
Means that the highest sound contained in the vocal part of a certain song a is Pa
H, the lowest note is PaL, and the vocal range of singer A is VA
The relationship between the pitches from H to VAL is shown. The tone range judging means 6 obtains PaH and PaL from the MIDI data of the music piece a by examining the highest and lowest tones appearing in the note number of the vocal portion. FIG. 4 shows singing human range data registered in the range data file 10. Voice range data, ie, VAH and VAL, corresponding to the singing person A specified by the singing person specification input are read from the range data file 10. In the example of FIG. 2, the singer A can play the low range of the song a sufficiently, but lacks the high range.

The mapping means 7 includes the outputs PaH and PaL of the sound range judging means 6 and the output V of the sound range data file 10.
AH and VAL are compared with each other so that the pitch of PaH-PaL is included in the range of VAH-VAL.
Decrease the note number of song a by H-Pa'H. The amount of the pitch to be lowered is changed so that the median of the range of the music piece a at the time of reproduction matches the median value of the range of the singing person A (median value matching) or the image of the original music is minimized. Pa'H can be equal to VAH to minimize the width.

FIG. 3 shows the relationship between pitches when the highest tone contained in the vocal portion of the song b is PbH, the lowest tone is PbL, and the vocal range of the singing person B is from VBH to VBL. . In the case of the example of FIG. 3, since the range of the vocal portion of the song b is wider than the range in which the performer B can utter, the singer cannot sing all the songs as in the case of FIG. In such a case, in the example of FIG. 3, the tune b is emphasized so that the performer B can sing the treble portion of the tune b.
Is shifted by PbH-VBH (highest pitch matching).

The actual pitch shift in FIGS. 2 and 3 is
For example, a numerical value corresponding to PaH-Pa'H or a numerical value corresponding to PbH-Pb'H from the note number of the MIDI information of the music a or the music b in which the center C is numerically expressed as "60" by the pitch conversion means 2. Is made by subtracting

In the embodiment of the present invention, the gamut judging means 6 for detecting the highest tone and the lowest tone included in the vocal portion of each music piece searches the highest tone and the lowest tone from the MIDI data, and determines the tone range. Although the judgment is made, for example, the MIDI data can be embedded in a part of the MIDI data in advance, or the sound range data can be recorded in the management information of the music data file 1. In this way, the calculation of the pitch shift amount can be simplified.

The pitch shift should be determined so as not to impair the image of the original music as much as possible. For example, other than the median matching and the highest tone matching as described in the embodiment, Depending on the method, they can be used in combination.

As described above, according to the present invention, the range storage means for storing the result of extracting the highest pitch and / or the lowest pitch included in the melody of the vocal portion of the music, and And a sound range storage means for storing a result of extracting the highest sound and / or the lowest sound that can be uttered by the singer, and extracting corresponding data according to the designation of the music and the singer. The pitch may be converted by comparison.
