DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic musical instrument that generates human voice sounds (in particular, an electronic musical instrument that changes the sound 1 of the six human voice sounds that is generated depending on the length of the pitch interval). Recently, there have been attempts to generate a human voice sound in an electronic musical instrument and use it as a hack chorus. A filmant filter is formed and used to generate human voice sounds, and the generated human sounds pass through the above filter, and are
By doing so, the island is established. By the way, if you listen to the 1st post's: #Peng's % sound spelled out, you'll fall for the Hayabusa theory, and while listening to it, you'll realize it's from your previous job, and it tends to become rc<.

Is it possible to change the phoneme in the middle of the concave? Therefore, K has to operate the phoneme selection switch etc. every time, and the operation becomes very troublesome, so it is difficult to play electronic musical instruments on 6. Undesirable.

This invention is based on the above-mentioned points.
) The length of lσ is the length of the inspector, and the length of the voice is the same as that of the human voice.・I'll explain.

The first is a basic block diagram showing an example of an electronic musical instrument according to the present invention. For example, upper keyboard UK, Jutentsugi LK, Betaru non-board PK, and each board UK.

K, a three-hit octave code 83 + B2 + B+ indicating the octave range of the pressed key, and a four-hit foot code N4, N3, N2, N+ indicating the note name.゜Also, the key-on signal KON is the same "1" that lasts for a long time (key press pressure), and even if the pressure is divided by 7% (~!!!!!!!! gi n"+), it becomes 01, The Otsu key code K is output from the 6th release B
C and C. Keogh>1 convex'q KON is supplied to the general musical tone signal form 8'L5 and the vocal sound detection section 6.

-ii'i H & 5 corresponds to the snoring assigned to each channel in response to the O key code KC and the key A signal KON K, which is given hourly from the pronunciation assignment capital 3 T6 The vocal sound detection section 6 generates a musical tone signal of each nayan sound that is suppressed by the d-board b1, and outputs it to the mixing stage section 8, which mixes the formed musical tone signals of each nayannel appropriately. This function detects human voice sounds (voices) from among the keys that are present, and is given in a time-sharing manner from the pronunciation assignment 3, and the 6 key codes KC and the key-on signal KON are activated during pressing. A predetermined one or a plurality of plows are selected from among the keys, and a vocal tone key food VKC and a vocal tone key-on signal VKON are outputted corresponding to the selected key and supplied to the vocal tone signal forming unit 7.

This vocal sound tester/l1 section 6 is configured as shown in FIG. 2, for example.

Regarding the license fee for the focal sound detection 96 shown in Figure 2,
A single rhombus corresponding to the highest note suppression trace is detected from among the traces of the pressing on a predetermined keyboard (UK, LK, or PK), and the highest note is restrained 1! K ground, hocal sound key code VKC and hocal sound key on number VKO
It is conjunctive and zatI so that it outputs N.

In FIG. 2, of the key food KC and key-on signal KON of each channel given in a time-divisional manner from the sound generation allocation section 3, 2°Kl for the keyboard code is input to the decoder 61, and the octave code B3 to B1% note code N4 to N1 and the key-on signal KON are input manually to the gate 62.

With Tecoder 61, 2. is added to the keyboard chord. Upper keyboard signal υ, lower keyboard signal L1 pedal that indicates the keyboard to which the lees assigned to each channel are assigned by tecoding K. 11@Shin@P
and these signals U.

The other human power r (of s is applied to each output signal of the upper i1! tree selection switch SUq lower keyboard selection switch SL% pedal birth selection switch SP. In this case, the selection switch su f SL + Sp is an appropriate translation of which keys to detect from among the pressed keys of the koji board when detecting the highest sound suppression trace in the vocal sound detection section 6.

When the rattan selection switch 80 is turned on, the switch g
From the trap that the output signal of o becomes 'bi', the AND gate A1
The upper keyboard signal U output from the Tecoder 61 is applied to the Enable holder E of the gate 62 via the gate G to make the gate 62 conductive. Therefore, the key of the upper keyboard UK is assigned to this cram key 6.
Channel key code KC and key-on signal KO
If N is given, Tecoder 61 will send the upper 1 board Gogo U ('1') to the channel timing of this channel.
Depending on the output of the signal), gate 62 conducts and passes the octave code B, A-B, note code N4 to N, and key-on signal KON of that channel. That is, the 7-cube food B about Jang Geol on @ @ U K! ~B, % note code N4~
Only the key-on signal vKOh of N and ε is selected by the gate 62 and added to the highest pitch detection circuit 63 Fc. In addition, when the fish selection switch SL or SP is turned on, the octave chords B3 to B+ and note chords of the chikinel assigned to the lower keyboard LK or petal keyboard PK whip or note code in the same manner as above and 10''. N4 to N, and the key-on signal KON is selected by the gate 62 to activate the pigeon sound detection (b) path 63e (added. In addition, the selection switch SU + S
When the dissipation switches are turned on at the same time in L + Sp, VC is the octave code B, ~B, , for each keyboard channel corresponding to the turned-on selection switch.
Note codes N4 to N1 % Key-on signals KON are all properly translated and added to the highest note detection (b) path 63.

, /-to codes N4 to N are detected. This detection shows the added octave code B ~ B1% note 1 hood N
The octave code B of i & side sound suppression traces detected as a result of the comparison is performed by sequentially comparing 4 to N1 of each channel in one cycle of 6 h.
3~Bl s note code N4~Nm is used in the next channel timing l cycle and output as vocal sound key food VKC. Also, the most 1tIl sound test
In J-co distribution 63rc, the local tone key-on signal VKON is not formed in connection with the above-mentioned highest tone detection and suspension, and this signal VKON is set to "0" when the highest tone pressed key is detected.
When a vocal sound key food VKC with the essence of other than the key code VKC is output, it becomes a B indicating a key press, and the bonito corner sound suppression wrinkle is no longer detected and the content of the key code VKC is 1.
When it reaches "0", it becomes 101, which indicates a confectionary whip. In addition, this local sound key A (VKON) is detected if 6 Iiaki Otoi F + weight has been changed, that is, the key code ■KC
(when the content of the VC improves) the VC is
becomes. This shortens the key-on signal VKON to #f threshold '0
"By doing so, it is possible to make a break when switching the hocal tone signal number formed in the hocal tone signal forming section 7, which will be described later, from the old highest-pressing key to the new strictly-pressing key. In order to make it clear, the vocal sound key hood hC and the vocal sound output from the vocal detection station 6 are
The on signal VKON is supplied to the vocal tone signal forming section 7.

The note length detection section 4 detects the length of the highest note pressed key detected in the actual tone detection h6, that is, the note length of the highest note suppression, and outputs a note length signal B. An example is shown in FIG.

In this actual k Il + t, the note length of the subside note pressed key is output from the focal sound detection unit 6),
The key-on signal VKON is detected by adding the time when it is in the V-shaped chest, at'tb.In other words, the vocal sound key-on signal VKON is delayed for a short time by the delay circuit, and is detected by adding the time when the key-on signal VKON is in the V-shape. (At the same time, the rising edge is differentiated by the differential circuit 11!!i', 41 and added to the reset manual force R of the counter 42.Roughly,
The vocal sound key-on signal ■KON is differentiated by the differentiation circuit 43 at its rising edge and is latched by the latch circuit 44.
Added to the power of the haiku poet. Now, when the vocal sound key-on signal VKON as shown in FIG. . Therefore, the count value of the counter 42 increases as the Pc vocal sound key-on signal VKON increases sequentially as shown in FIG. At that point, the generation of the count value stops.Then, when the hocal sound key-on signal VKON becomes VKON, the sudden division circuit 4
The count value of the counter 42 is recorded in the latch circuit 44 by the output of 3 (valve, Figure 4 (c)), and immediately after that, V
(The counter 42 is also reset.) In this way, the latch circuit 44il'c latches the length of the most cylindrical tone pressing force, that is, the take that is one center to the note length, and outputs it as a note length error. .

Vocal sound signal type & random 7 is vocal sound production - food V
KC2) This is to form and output a musical tone signal corresponding to the key-on signal VKCNke (based on I9T foot), and the phonology of the musical tone signal to be formed is note length extrusion 酜4.
F) is changed by the code length signal B given from F). In the vocal musical tone signal type a section 7, musical tone signals corresponding to each of the human voice sounds are generated in a predetermined order or in the fI-men order based on the note length signal Jg58 output from the note length detection section 4. , when the note length signal B) of the highest note pressed key on the keyboard changes, tFjIi changes accordingly.
will also change. Note that the pitch of the musical tone signal formed by this musical tone signal forming capital 7 is the key code VK.
The bowl shown in C is a bowl that is tightly rounded.

This hocal tone 1 number formation part 7,? The musical tone signal of the human voice output from 7 is supplied to 8, where it is mixed with the musical tone signal corresponding to each pressure signal output from the general musical signal forming section 5. A sound system 9 consisting of an antenna 7, speakers, etc. is used to produce musical tones.

Down, vocals, music signal type F! I will explain about Suyohi Hagisaku's construction of x Miyako 7.

The fifth example shows an example in which the hokal music tone Hakugo formation capital 7 is configured using a titital filter. Leverage Tough 1 detects note length f! From the note length signal B output from the note length signal B output from the note length signal B, the selection signal S is decoded to select the predetermined phoneme corresponding to the decoded value. It is supplied to address signal generation h72 and selector 74.

In this case, the note length signal B outputted from the note length detection section 4 is a digital value, and the value changes frequently.Therefore, in the Tecoder 71, only the upper predetermined bit of the digital value is used as a note length signal. It is preferable to output the electrodeposition signal S of bl corresponding to the decoded value (i.e., ignore the lower bits).

In place of the tehuta 71, it is also possible to use a switching control circuit as shown in FIGS. 6 to 8. The phoneme switching circuit 171 shown in FIG. Shinkau〉ri 171b and Tekota 17
Compare note length signal B from n1 note length detection capital 4 with 4% correction from 1C and V (!21 Compare with 171a to determine whether B≦K (that is, detected note length or predetermined length below) when t
Rhyme fJ! m number P is output, this phoneme switching signal P is counted by the M-ary counter 171b, and the phoneme switching signal P is outputted by the Tekota 171C.
From there, a tone selection signal S corresponding to the count value of the counter 171b is outputted in a predetermined order (for example, A, T, O, U, R). When the sound i selection signal S changes to a predetermined degree, it returns to the electric protection phoneme switching signal S and thereafter repeats the same pattern.

72 is a ratio &7& of the same configuration as the comparison circuit 171a of the actual & example shown in Figure 6.
t72a, the 2iLI number occurrence story 172b that occurs in the order of the number rlJ to rMJ 'F appointment, and the comparison circuit 172a.
When receiving the Hk 9i k signal P from the random number generator 17
Disturbance generated from 2b] Latch times to latch data %1
72c, and a Tekoter 172d for decoding the random number take that is latched by the latch circuit 172C and outputted.
72b outputs a phoneme selection signal S corresponding to the random data processing, which is randomly generated. In this case, the order of the keystrokes in the meeting is quite chaotic. Long signal B'b - 6 tones such as 'B' when it is smaller than the predetermined length, and IO# when it is larger than the specified length & 9. When the phoneme switching signal P is #1', the 6° selector 173b differentiates the rising edge of the focal sound key-on signal VKON, that is, the signal added to the human power, by the Ayu 173C. Select and output the O signal, and output the O-kiri & L signal P or θ.
', the b signal Tt-, that is, the ratio 'j:J of the differentiating circuit 173c, is divided by the frequency dividing circuit 173d, and 100 b' is selected and output. The counter 173e counts the output of the selector 173b, which is decoded by the sword toy idiot encoder 173f and selects a phoneme corresponding to the count value (output as No. 8 S. As a result, the length of P+11!! is the note length. When the length is shorter than the predetermined length, the count value of the counter 173e increases at a high speed, so that the cutting of the sound is performed faster than the opening of the grasp.

Returning to Figure 5, the address signal generator 72 detects this sound mb selection signal S and the vocal sound detection E! Based on the vocal sound key-on signal VKON output from fJ6, an address signal ADH for reading out the coefficient take stored in the coefficient memory 73 is output for each phoneme.

FIG. 9 shows @ in one part of this address signal generating section 72, and its four functions will be explained based on FIGS. 10 and 11.

In the 9th bacterium, sound 1 selection color number S or address signal generation &
72, the attack pulse is generated, and the attack pulse A is composed of the rising song of the human voice.
In addition, the active pulse generation circuit 11 generates a dynamic pulse DP that assembles the falling state of a human voice sound, and the sustain address memory 12 generates a coefficient for generating a long-lasting part of a human voice sound. a sustain address A that is in charge of the read-ro 1 address from the memory 73;
or generated respectively. In this case, attack pulse),
P and TK pulse DP+/) periods are respectively numbered according to the phoneme indicated by the sound*red selection signal S,
The attack pulse generation circuit 10 and the sustain pulse generation island 11 are generated by, for example, the sound sushi universal selection signal S, so that the number of oscillations is 1b11, t''+Otsu oscillation. Address A is recorded in each address corresponding to each phoneme, and ftmm selection @sign S is input as an address signal 2!t
By doing so, the sustain address A, which is set to the six-tone garden indicated by the signal S, is read out.

Now, whether the vocal sound detection capital 6 or the address signal 4i is as shown in No. 10 (A),
When the fj light generating section 72 is manually operated, its rising edge is differentiated by the differential 1 path 13Y and a key-on pulse KNP is output. This key-on pulse KNP resets the counter 17 and also sets R87 lip 70 to 715. From the fear K, the AND condition of AND gate A4 is satisfied and the attack pulse AP or AND gate A4,
Since the attack pulse AP is input to the counter 17 via the OR gate G4, the counter 17 starts counting the attack pulse AP. At this time, the AND condition is not satisfied and the decay pulse DP is not supplied to the counter 17 since the R8 flip 70 and the flip 16 have been reset as will be described later. The 11th row shows a change in the count value of the counter 17 over time, and the counter 17 counts attack pulses AP and sends the counted value to the coefficient memory 73 as an address signal ADH. When the count value of the counter 17 becomes equal to the sustain address A1 outputted from the sustain address memory 12, a match signal EQ is outputted from the comparator 18, and the RS flip-flop resource 15 is reset. As a result, the AND condition of AND gate A4 no longer holds true, and the attack pulse AP is supplied to counter 17JC and 1,
The counting line of the counter 17 remains stationary at the 9th address A. This count value (person) continues to be output as the address signal DR. This 1* state continues until the one-tone key-on signal VKON is asserted. When the vocal sound key-on signal VKON rises, differential path 14
The key-off pulse KFP is output by detecting the falling edge of the key-off pulse KFP. As a result, %R87R170Tub16 is set, so the AND condition of Antogame S is satisfied, and the TK pulse D generated from the TK pulse generation circuit 11 is
P is input to the counter 17. From this IK, the counter 17 calculates the pulse D from the above-mentioned count -(A,).
Do a count of P. During this time, the count value of the counter 17 is also sent to the coefficient memory 7 as an address signal ADH.
It was sent on 3rd. After that, when the count value of the counter 17 reaches the maximum value N (all bits are 'bi'), the AND condition of the AND gate A6 is satisfied, and the RS ';'
Tsubu 16 has been reset. As a result, Tika Pulse D
The input of P to the counter 17 is stopped, the count value of the counter 17 is stopped at the maximum value N, and this count value N is stored in the coefficient memory 73 as the address signal ADR.Returning to FIG. 5, the explanation will be as follows. General busy human voice sounds are created by combining voiced sounds and unvoiced sounds and passing them through a fixed 7-ormant filter. Therefore, the Ks number memory 73 contains the sounds that you want to generate as human voice sounds - (for example, [a], "Tsu",...
A memory 73a for each phoneme stores the number of voiced and unvoiced sounds necessary to form musical tones such as "ru", "wa", etc., and Parcor coefficients that determine the ormant characteristics. 73b.
The address signal -j3 ADR as shown in ] is output and the memory 73 corresponding to each phoneme of the coefficient memory 73 is output.
a r 73 b +-・Each address “0” to rNJ
The voiced & transverse coefficients, unvoiced amplitude coefficients, barcode coefficients, and barcode coefficients as shown in FIGS. are supplied to input terminals 1 to MK, respectively. The selector 74 selects the voiceless eii+coefficients output from the coefficient memory 73 corresponding to each phoneme,
Voiced f/7! Among A coefficient and Percoll coefficient, sound *i
Based on the M selection signal SK, only the coefficients (unvoiced 1111 coefficients, raised amplitude coefficients, and percoll coefficients) corresponding to the predetermined sound are translated and output.In this case, for example, voiced sounds such as the phoneme of [A] In that case, the unvoiced amplitude coefficient is set to zero VC, and if the voiced sound is mixed with the unvoiced sound at the beginning of the sound, such as the sound koji of "ba" or "yu", the voiced amplitude coefficient is set as shown in Figure 1θ. As shown in (C), it increases slowly over time, and as shown in (C), the silent Garya coefficient has a sharp peak for a relatively short period of time at the initial rise, and then becomes zero. It is set as follows.

It should be noted that the Percoll coefficient is set to vary from time to time in the rising and falling parts of the sound, as shown in (4 times -).

Of the voiced sounds and unvoiced sounds forming the human voice, the unvoiced sound signal is generated by multiplying the noise signal output from the noise sound source 75 serving as the sound source by the unvoiced sound amplitude coefficient output from the selector 74 in a multiplier 76.

On the other hand, a voiced sound signal is generated as follows. Masu Cup Board 81
From the single wave number memory 77, which is composed of a ROM, in which the frequency number F (constant) corresponding to each part of >1 is stored in advance for each address, the vocal sound key code ■CK
The frequency number F stored in the specified 6th address is read out. The number F of the pigeon wave read from the same wave number information memory 77 is constant F# in the accumulator 78.
The accumulated value is stored in the sound source waveform memory 7.
It is output as the address signal of 9. Sound source waveform memory 7
9, 61 MII values at each sample point obtained by dividing a basic waveform for producing a voiced sound (for example, one phase of an asymmetric triangular wave) into II number of sample points are stored in each address as digital data. , this amplitude value is sequentially read out from the accumulator 78 based on the output error 6 address false signals. The raised sound source signal read from the sound source waveform memory 79 is multiplied by a device frequency Ik*, which is composed of the selector 74, in a multiplier 80 to become a voiced vehicle signal.

The voiced sound signal thus shaped 1& is added to the unvoiced sound signal output from the multiplier 76 in an adder 81, and is supplied to a digital filter 82.

The digital filter 82 is, for example, disclosed in Japanese Patent Application Laid-Open No. 56-12
As shown in No. 5798, the 7-ormant of the tone l is shaped by a number of filters each consisting of a plurality of multipliers, an adder, a memory, and a trap, and its filter characteristics are is controlled by the percoll controller 1 from the selector 74, and a human voice sound signal (focal musical sound signal) corresponding to a predetermined spontaneous sound is heated.

Suice. The digital human voice signal outputted from the digital filter 82 is converted into an analog focal musical tone signal by the D/A converter 83rC. Thus, the focal musical tone signal generated from the focal musical tone signal type #i, R7 is as follows. , 1st
As shown in the figure, the musical tone signal generated from the general musical tone number ``B&5'' is mixed in the mixing section 8rC, mixed, and output from the sound system 9.

Vocal musical sound signal formation &7 is based on the above-mentioned gain digital filter method, CX> A seven-ormant filter is constructed by combining multiple analog four-band pass filters, and the center wave number and resonance characteristics of each band pass filter are adjusted individually. An analog filter method that controls 1jII in response to the sound ti+ (for example, see Japanese Patent Application Laid-Open No. 55-77799), C
2) Is the amplitude of each high my component of the harmonic component generation (b) path coarsely controlled in accordance with a predetermined phoneme? (3) 7 ormant formation (b) paths of E and Wlk that execute frequency modulation calculation are provided in #, and 7 of each 7 ormant formation circuits are provided. A set of frequency changers that control the center frequency, level, and spread of the ormant for each note to form seven ormant characteristics of one phoneme (for example, Japanese Patent Laid-Open No. 55-1
No. 8623*), etc. 6゜As a means for generating musical sound signals of human voice sounds, 1. The waveform of a human voice with a desired phoneme itself may be directly stored in the drum-shaped memory and read out. Six methods for storing human voice waveforms in this J#j type, T& type memory include PCM.
(Pulse Code Modulation), APCM (Adaptive Pulse Code Modulation)
, DPCM (differential pulse code modulation), ADPCM (
Adaptive differential pulse code change i), DM (delta modulation), LP
There are various systems such as CM (N-type pulse code modulation) 7:L, but any of them may be used. Furthermore, in such a storage method, by providing a waveform memory that stores each pitch as well as the above-mentioned human voice sound t&form, a more natural human voice pitch can be obtained.

In the actual and example of the electronic musical instrument according to the present invention, only the LB is used as the human voice sound to be produced when the highest note of each suppression key is pressed. Alternatively, human voice sounds may be generated in response to each key on the upper, lower, and pedal S boards, or in response to all keys pressed. Good too.

Furthermore, the range of the human voice to be produced may be different from the range of the pressed key (for example, the human voice may be produced in a range one octave above or below the range of the pressed key). Further, in the above embodiment, the general musical tone number formation capital may be omitted as appropriate so that only human voice sounds are produced. Alternatively, the length of the pressed key (note length) may be detected based on the output of the pressed key detection sS2 or the output of the pronunciation assignment f&3. In addition, instead of the ``N'ljU'' method for processing press and release signals from the keyboard, a ``direct chest contact'' method was used that directly processed the signals from the on/off switches provided for each pot. It can also be used.

You can also pre-program the phonetic sequence before the human voice is pronounced and store it in memory! It is also possible to leave it out and read out the memory contents in sequence based on the length of the key pressed, that is, the note length, and to switch the 1#- of the 6 human tones that are produced by sequentially reading out the memory contents using the O tone self-switching signal. . The phonetic 7 of this sharp five-person voice
0 grams may be arbitrarily expressed by the player of the electronic musical instrument. Incidentally, the present invention can also be realized in an electronic musical instrument in which the keyboard section consists of a single-stage grip board.

As described above, in this invention, the phoneme of the human voice sound to be pronounced is changed according to the length of the key pressed, that is, the note length of the note, so the phoneme of the human voice sound is automatically changed without the need for troublesome switch operations. IlZ2! You will be able to pronounce human voice sounds that are rich in variety, without the monotony of traditional methods.
