It is explained in

As pointed out in this paper, most research in this field has focused on speaker-specific devices, that is, speaker-dependent devices, and language recognition devices, which are speaker-independent devices. Ta. The former can only recognize words spoken by one individual, while the latter can recognize the same words spoken by different people. A speaker identification device can recognize (or learn) a larger number of words simultaneously than a speaker-independent device, and therefore can control more functions. Both devices work by creating a template of spoken words and matching the received words to this template.

There has been a great deal of effort in this field, and there are many patents and articles as evidenced by a search of the technical literature in the prior art description of Marley, US Pat. No. 4,284,846. This prior art patent teaches an apparatus for analyzing and comparing words by comparing certain waveform characteristics to pre-stored ratios.

Other patents disclosing language recognition devices include U.S. Pat.

These devices are either extremely complex and expensive, or otherwise have very limited capabilities. For example, some typical speaker-independent devices may recognize about 10 words (e.g., 10 different numbers), while speaker-specific devices may recognize an order of magnitude more, or 100 to 200 words. be.

1 ri imperial amount! The present invention differs from the apparatus disclosed in the above-referenced patents by:
They differ in their relatively low complexity.

That is, in order to economically implement a speaker-independent device capable of recognizing a large number of different voice commands, the present invention provides a range of human speech that extends far beyond that required or commonly used in normal conversation. There is a physical advantage to being able to use your voice.

A device according to the teachings of the present invention senses and recognizes differences in sounds that are treated as encoded signals to perform a predefined function.

According to a feature of the present invention, this difference in note is a note within a scale, such as a normal diatonic scale, for example, the difference between the user's middle C note and the two subsequent notes. By comparing the tones, a means is provided for setting the tonality (key) for each user. The device of the invention uses and recognizes pitches as commands or inputs.

This device has many applications including computer input and M control in environments where other input devices are impractical.

That is, the present invention is useful where a user must use their hands in a darkroom (eg, in an electron microscope room) or during other operations such as manufacturing processes. The device is useful for people with disabilities, especially those who cannot easily operate conventional computer terminals.

The recognition device of the present invention, together with its advantages, can best be understood by the following description with reference to the accompanying drawings. In the drawings, like components are given like reference numerals.

The principles of the present invention can be applied with hardware and/or software in a variety of ways, some examples of which are described below.

The device according to the invention, as shown in FIG.
Indicated by reference number 10. Apparatus 10 includes a transducer 12, such as a microphone, which collects audio waves, such as that shown by waveform 14. The above waveform has a fundamental period T relative to the rate of the fundamental frequency (pitch) when a human is singing the C note. In order to simplify the electronic circuit system, the electrical analog signal of the received audio waveform 14 is converted into a pulse wave train 16 with a period T in a waveform shaping circuit 18.

Instead of the converter 12, an auxiliary electrical signal input 2o may be provided, which may be, for example, a telephone input for remote activation or a voice generator.

The wave train 16 is received by a period measuring circuit 22, its period is measured and converted into a numerical value, and the information is sent to an input/output interface 24 that interfaces with a numerical electronic calculator 26.

In the overall operation of the device 10, the device 10 receives audio signals at the microphone 12 or input 20 and executes preprogrammed routines within the computer in response to selected signals from the received signals.

In order to understand the principles regarding the operation of the device 10 of the invention,
An application example will be explained with reference to a normal diatonic scale. It is thereby understood that the present invention is applicable to other scales as well. The modern diatonic scale has intervals that are independent of the frequency of a particular note (but once one frequency is set, the frequencies of other notes are determined by it), and can be partially expressed by the table below. .

Any diatonic scale Interval Ml' 2.5000 RE' 2.2500 DO' 2.0000 Tl 1.875O LA 1.6667 So 1.5000 FA 1.3333 Ml 1.2500 RE 1.1250 Standard scale Do 1.0000 Tl, 0.93750 LA, 0.83333 Do, 0.75000 FA, 0.66667 MI, 0.62500 RE, 0.56250 Do, 0.50000 T1. 0.46875 Most people are familiar with this pitch, and even children can immediately sing C, S, E, F, G, U, C, C (in this case, unconsciously choose the reference frequency and sing the above pitch). (which relates other sounds to a reference frequency). The present invention selects a pitch as a means of receiving information and processes it.

Accordingly, referring to the flowchart of FIG. 5, the start command may be the receipt of the audio signal detected in step A. In step B, this signal is measured to determine whether it has a period of sufficient duration (to prevent false activation)
. If there are reference signals and they are stored (e.g. C), they are compared and the interval of 1.125 is calculated in step C, then the fetch/execute subroutine is executed in step D and the previously recorded The subroutine for pitch 1.125 is called and executed. Finally, the system is reset in step E, ready to receive and respond to a second signal (eg, F) in a similar general manner.

In order to avoid making the system speaker specific and to make it usable by anyone with minimal musical ability, the reference signals are set with identical processing. When starting up, the user simply blows a short "C" followed by "C" into the microphone. The system uses the first received audio signal for setting a reference signal, and treats the second and subsequent signals as command signals.

FIG. 2 shows a preferred embodiment of the waveform shaping circuit 18 and its interconnections to the microphone 12 and auxiliary power 20. The electrical specific values of the components used are shown in the diagram.
Many other values can of course be used, as is well known to those skilled in the art. However, the values and connections of the circuit elements of FIG. 2 were good in the prototype device.

Specifically, microphone 12 is connected between active impedance 27 to circuit connection point 28 and chassis ground. Connection point 28 is connected to chassis ground via a resistor 32 and to auxiliary human power 20 via a capacitor 34 .

When a signal is received at signal input 12 or 20, input 12
or 20 sends the received signal to a low frequency amplifier 36 that includes an operational amplifier 38 . The negative input (pin 6) of amplifier 38 is
Connected to connection point 28, positive power (pin 5) is connected to bias voltage (+5 V) through resistor 40, capacitor 42 and resistor 4
Connected to chassis ground via 4 parallel connections. Pin 4 of operational amplifier 38 is connected to a positive bias source (12V) through a current limiting resistor 45 and to chassis ground through a capacitor 46 . A part of the output of the operational amplifier 36 is fed back to the negative input via a resistor 47 and a capacitor 48 connected in parallel.

The main output of amplifier 38 is fed to a low frequency filter including resistor 51. One end of the resistor 51 is connected to the output of the amplifier 36, and the other end is connected to a ground point via a capacitor 52, and to a circuit connection point 54 via a resistor 53. The output of the low frequency filter 50 is connected to a node 54 and further connected to a comparator 55 and a maximum voltage follower circuit 56 with attenuation. The signal is
(a) Comparator 55 whose input is grounded via resistor 59
(b) is connected to the main positive signal input (pin 12) of the operational amplifier 58 through the current isolation diode 57 and to the maximum voltage follower circuit 56 (b). The output of circuit 56 becomes the main negative signal input to the input pin of comparator 55 (pin 13).

Circuit 56 preferably includes an operational amplifier 60 whose main positive input (pin 3) is connected to node 54 and whose output (pin l) is returned directly to the negative input (pin 2);
A portion is connected to the negative signal input of the amplifier 58 via the isolation diode 61. The output of resistor -60 is grounded via resistor 63 and capacitor 64. Resistor 63 connected in parallel
and the discharge time constant of capacitor 64 are such values that, except for the maximum effective value of each cycle of the signal appearing at node 54, the inverting input at comparator 55 always has a greater influence than the non-inverting input.

Waveform 16, which is the output of comparator 55, is obtained from the junction of a pair of resistors 65 and 66 connected in series from the output of operational amplifier 58 (pin 14) to ground. This output is sent to the input ST of the period measuring circuit 22.

FIG. 3 shows a preferred embodiment of the interconnection of period measurement circuit 22 to input/output interface circuit 24 and computer 26. The specific computer 26 is preferably Apple■1
, and the specific interconnection to that computer is shown here.

The puffless column 16 is coupled to a shift register 72 via an operational amplifier 70 with a Schmitt trigger.

The output of register 72 is coupled to counter 78 via inverter 74 and period measuring gate 75. Counter 78 is connected to computer 26 via buffer 80.

The output of the computer 26 is R/W, AO, Al, and D S
The (device 5elect) output is obtained from the bias source (5V) and timing pulses and is provided as shown in FIG. Gates 81 and 82 are connected to signal line 83
This is for sending a reset command via the .

The circuitry of FIGS. 2-3 and the function of computer 26 will become clearer with reference to FIG. Figure 4 shows waveform 14.
．． 16 and input at CP of shift register 72, calculator 2
6 to the period measurement circuit 75,
and the correlation of the outputs of the shift register 72 corresponding to the beginning and end of the measured period T.

Explain the operation. The circuits of FIGS. 2 and 3 firstly require that the input signal 14
into a shaped pulse train 16. Calculator 26 resets shift register 72 and counter (via signal line 83 and inverter 86) and sets up the circuit for the next period measurement.

When the first rising edge of the shaped pulse train 16 appears at CP of the shift register 72, the output QO changes from a low (voltage) level to a high level. counter 78
begins measuring the current period of the input wave train.

The shaped pulse train 16 is applied to the CP of the shift register 72.
When the second rising edge of Q1 arrives, the output Ql goes from a low level to a high level. Counter 78 stops counting. At the same time, the input of the most significant digit of the high-order byte buffer 90 of the buffer 8'o is set from a low level to a high level, indicating that the period measurement is completed.

Calculator 26 reads high byte buffer 90. If the most significant number is a high level, it will be ignored and the calculator 26 will:
The lowest 7 bits are converted into 15-bit binary numbers Q8 to Q14.
Evaluate as. (A low level of the most significant digit indicates that the period measurement is not yet complete.) Calculator 26 also reads low byte buffer 92 and reads 15
The lowest 8 bits of the bit binary number, QO to Q7, are read values. The calculator 26 takes the size of this 15-bit binary number as the size of the period just measured.

The operation of the device 10 can be better understood from the flowchart of FIG. 6. In FIG. Taka is judged. If not, the system waits for that signal. If received, take a reading at B3;
In B4, it is determined whether the third pulse (any number is acceptable, for example, the 300th pulse) of the same pulse period can be used for average value calculation in step C.

The flowchart of FIG. 6 is for a single pitch message. This is for separate reference and signal wave train inputs, there is always a break between successive wave trains, block! is the step for detecting these breaks.

If the output of block I is the first audio signal detected, that signal is treated as a reference signal and stored. Once the second and subsequent signals are identified, they are compared to the reference signal and the pitch is calculated. The calculated pitches are checked to see if they are missing, and if a match is detected, the associated subroutine is executed and the program is reset.

In an actual example, a computer terminal could display a menu like the one below.

If it is replaced with , it becomes possible to process an input with a slur, that is, a wave train with a slur. This action is advantageous to the speaker because it is easier to create slurred (concatenated) speech than individual speech.

The following is a step-by-step guide to implementing the program in Block ■.

2420 PRINT CHR$ (7): REM
BEEP FORN1xr WAVERAIN 2460 for PS=I TO500: NEX
T: REM PAUSE This is, for example, FIG, 6
Line 24 of the program listing for the flowchart of
20 to 2485 can be substituted. The pause in Figure 9 is sufficient to prevent the current wave train (flowcharts in Figures 6-8) from being mistaken for subsequent readings, e.g. The user should be careful not to continue to generate such wave trains for a length beyond the rest.

FIG. 10 shows another alternative subroutine (2).

Block 3 modifies the device IO so that the user can actually extend the frequency range by generating and holding the wave train output for longer than normally required. That is, it is sufficient to generate and hold the data beyond the pause time. When the device detects a wave train lasting longer than a predetermined duration, it modifies said data using a transformation factor to obtain the effective pitch before message identification (i.e., before interpretation). do.

The symbol m shown in block ■ in FIG. 10 is a conversion coefficient, which can take any value within an arbitrary range. Two specific values 0.5 and 2 are particularly useful when the speaker is a human. The coefficient is m =
0.5, the device listening section transposes to a higher octave,
When m=2, it moves to a lower octave. (That is, Doμ is the interval 1.125. If m=5 and RE is held, measure the interval 2.5, that is, D〇-RE').

Repeated transpositions are performed when the speaker or singer continues the wave train further. That is, the speaker's frequency range is substantially expanded. Furthermore, speech power allows the user to operate within a convenient frequency range, yet achieves a large number of pitches as if the speaker had a very wide frequency range. Therefore, using only a few notes, more different word signals than before can be obtained.

A suitable listing for the program in block ① of FIG. 10 is shown below.
