Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a voice program input method.

[Prior art and its problems] Conventionally, for example, when a user creates a program in a personal computer, an electronic robot, etc., an input method using key operations is generally used. Digital data is stored in a storage device such as a cassette tape recorder.

However, it is very troublesome for a user to create a program by operating keys, especially for beginners, who must understand how to use the keys manually. Furthermore, it is difficult to create a program, not only for those who are not familiar with keys, but also for those who are. Furthermore, in the case of a playback programming method in which programs are created while operating the robot, as with electronic robots, programs must be created while looking at both the robot and the keys, making it difficult to create programs easily. There was a problem.

[Object of the Invention] The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a voice program input method that allows a user to easily create a program by inputting program data by voice.

[Summary of the Invention] The present invention records user's voice input commands specified in advance on a storage medium while maintaining a predetermined mute interval, and also records any command among the above commands by voice input while maintaining a desired interval. This makes it possible to create a desired program by recording the program using the computer, and eliminates the need to input programs through complicated key operations.

Next, the configuration of the electronic circuit provided in the electronic robot 1 will be explained. In FIG. 2, 21 is a receiver;
A high frequency signal sent from a wireless microphone 1 is received via an antenna 6. The wireless microphone 7 mentioned above is
It consists of a microphone 7a and an oscillator 7b, and the oscillator 7b outputs a high frequency signal in response to audio input to the microphone 7a. Therefore, the receiver 21 is
Upon receiving the high frequency signal from the wireless microphone 7, the received signal is demodulated and output to the preprocessing circuit 23 via the analog switch 22. This preprocessing circuit 23 is composed of, for example, an amplifier and a filter, and amplifies the audio signal from the receiver 21 and outputs it to the CPU 24.

Further, the output signal of the receiver 21 is sent to an amplifier 25. This amplifier 25 consists of a preamplifier and a power amplifier, and amplifies the audio signal from the receiver 21 to drive the speaker 10. Further, the MT9 is connected to the amplifier 25, and the output of the amplifier 25 is recorded.

Further, the amplifier 25 amplifies the reproduction signal of the MT9,
The output f of the preamplifier is outputted to the preprocessing circuit 23 via the analog switch 26. Analog switch 2 above
2.26 is controlled on/off by control signals a and b from the CPU 24. Further, the amplifier 25 has M

A motor drive circuit 32 is connected. This motor drive circuit 32 includes a drive motor 33a for the left leg 5a and a drive motor 33a for the right leg 5.
The drive motor 331) of b is controlled.

Next, the operation of the above embodiment will be explained. Now, electronic robot 1
The robot executes seven types of commands: ``forward,''``right,''``left,''``backward,''``pause,''``stop,'' and ``repeat.'' In the above command, "temporary stop" is a stop in operation, and the motors 33a and 33b are in a stopped state, and the MT9 is in an operating state, and "stop" is a stop in the system, and the motors 33a, 33b and MT
9 are both in the stopped state. Furthermore, "repeat" is an instruction to repeat an operation, and is executed only in the program P mode.

Therefore, the mode switch 14 causes the manual M1
, M2, and program P can be specified, and these three modes have the following functions.

The mode of the manual M1 is specified when inputting the voice of "registration/recognition" from the wireless microphone 7. At the time of registration, the registration/recognition changeover switch 11 is set to the registration state and the voice is input. After registering the first voice input, if the user wants to register the next voice input, the step key 12 is operated. Further, when recognizing input speech, the registration/recognition changeover switch 11 is set to the recognition state. In this state, step key 1
2 is a non-operation. In addition, in the recognition state, if an operation command such as "stop" or "repeat" is recognized, the system will enter a stop state, so to cancel it, press the start key 13 or turn off the power once. After turning it off, turn it on again.

The manual M2 mode becomes microphone input when MT large input is recognized at the time of registration. At this time, the registration/recognition changeover switch 11 and step key 12 are non-operational, and the functions of registration/recognition conversion and step key 12 are performed automatically. The following mode is similar to the mode of manual M1.

In the mode of program P, "registration/i!! knowledge"
Input from MT9. At 11 o'clock in "Repeat", M
T9 is returned to the program start, and the program is repeatedly executed from the start of the program to ``repeat Jl1ME.'' The previous recognition operation continues from the time of ``repeat'' recognition to the return to the program start. The rest is the same as manual M2.

The operations in the manuals M1, M2 and program P are displayed as symbols on the LCD 15. Also, MT
The control key 16 is a key for manually operating the MT9, and during this manual control, the control signal d from the CPU 24 to the MTCI thick control circuit 29 is at a low level.

Next, the MT format of the audio program system will be explained with reference to FIG. Figure 3(a) shows the MT format at the time of registration, with 40 cassette tapes.
An instruction registration area IE of a predetermined length is provided from the first start position SOT of
The seven types of instructions 418 to 41g for
Recorded with ute intervals maintained. Above Mute! is the tape's IRG (inter recording gap)
Therefore, an interval longer than the start/stop time of MT9 is required. The above instruction registration area IE is manual M
2 and program P modes. The cassette tape 40 is provided with a program area PE that is used only in the mode of the program P, following the instruction registration area IE. The executed program will be recorded. In FIG. 3(b), 42a, 42b, . . . are commands registered in advance in the command registration area IE, that is, “forward”, “right”, .
. . . etc. are appropriately selected (that is, programmed) voice commands, and 43a, 43b, . . . indicate the duration of each of the voice commands 42a, 42b1, . That is, a mute time is provided between each of the voice commands 42a, 42b, . . . to correspond to the duration of each command.

Next, voice registration and robot control operations will be explained with reference to the flowchart in FIG. The flowchart shown in FIG. 4 is executed under the control of the CPU 24. In order to operate the electronic robot 1, first, the CPU
Seven types of instructions are registered in the 24 internal memory (not shown). When registering this command, if registration and voice input are to be performed manually, set the registration/recognition changeover switch 11 to the registration state, select and specify the mode of manual M1 with the mode switch 14, and register from the wireless microphone 7. Voice input of seed commands. CPU 24
In step A1 of FIG. 4, mode switch 1 is
The mode specified by 4 is determined. If manual M1 mode is specified as above,
Proceeding from step A1 to step A2, the designated mode of the registration/recognition changeover switch 11 is determined. If the recognition mode is designated, the process remains on standby, but if the registration mode is designated, the process advances to step A3.

When the CPU 24 proceeds to step A3, the CPU 24 outputs the signals a and b.
is set to O'', analog switches 22 and 26 are turned off, a stop signal is sent to the motor drive circuit 32, and a stop signal is sent to the LCD drive circuit 3.
1 is a signal for lighting up the "registration" and "forward" displays, and a signal d for instructing "rewind" is output to the MT logic control circuit 29 to clear the mute counter. The MT logic word control circuit 29 causes the MT 9 to rewind the tape in response to a rewind command from the CPU 24.

Then, when the MT 9 completes the tape rewinding operation, an MT stop signal is sent from the amplifier 25 to the CPU 24. The CP Ll 24 detects the MT stop signal from the amplifier 25 in step A4, and proceeds to step A5. In step A5, the CPU 24 sets the signal to the analog switch 26 to #1ff. Thereafter, the process advances to step 86 and waits until audio is input from the wireless microphone 7. The user follows the input guide "Forward" displayed on the LCD 15 and inputs the corresponding voice from the wireless microphone 7. The voice input to the wireless microphone 7 is modulated by the wireless microphone 7 and sent to the electronic robot 1. electronic robot 1
receives the signal from the wireless microphone 7 through the antenna 6, inputs it to the receiver 21, and demodulates the audio signal. The audio signal outputted from this receiver 21 is amplified by an amplifier 25, and then sent to a Bunalog switch 26 and a preprocessing circuit 2.
3 to the CPLI 24. CPU 24
detects the above voice input in step 80 and proceeds to step A7. In step A7, the input audio data is compressed and stored in the internal memory of the CPU 24. After erasing any display other than "registration" or "recognition" on the LCD 15, the process proceeds to step A8, where it is determined whether the mute counter has reached r+IJL and the count has reached "7". If the content of the mute counter is less than "7", the process advances to step 80, and it is determined whether the step key 12 has been operated. If the step key 12 has been operated, the process advances to step A10, and the L
The input guide for the next registration command, for example "right", is displayed on the CD 15 and the process returns to step A6. The user has L CD 1
Look at the input guide displayed in step 5 and issue a registration command for it.
In this case, "right" is input by voice from the wireless microphone 7.

Thereafter, similar processing is repeated to store seven types of instructions in the internal memory of the CPU 24. Then, when the registration process of the above seven types of commands is completed, the count value of the mute counter will be "
7'', the process proceeds from step 88 to step All, where it is determined whether the registration mode is the recognition mode or not, and if it is the registration mode, the process remains on standby. On the other hand, when the user completes the registration of the above command, the user registers/i! The recognition changeover switch 11 is switched to the recognition mode, and then a voice command for actually operating the electronic robot 1 is inputted from the wireless microphone 7. When the II mode is specified by the registration/m recognition changeover switch 11, the CPU 24 proceeds from step A11 to step A12, erases the registration symbol and lights the recognition symbol on the LCD 15, and then switches the audio signal to step A13. Determine whether the input has been made. If there is no voice input, step A14
, and the mode switch 14 is in manual M1 mode, or manual M2 or program P.
mode. If the mode is manual M2 or program P, the process returns to step A13, and if the mode is manual M1, the process proceeds to step A15. In this step A15, it is determined whether the registration mode or the recognition mode is designated by the registration/recognition changeover switch 11, and if the recognition mode is designated, the process returns to step A13. If it is determined in step A13 that there is a voice input, the process proceeds to step A16, where the voice is recognized, compressed, and stored in the internal memory. Also, at this time, the mute counter is set to r+1JL, and the process then proceeds to step A17. In this step A17, the registered voice compressed data previously stored in the internal memory is compared with the recognized voice compressed data stored in the internal memory in the above step A16, and "forward", "right", "left", etc. Determine whether the command is "backward,""pause,""stop," or "repeat," and proceed to step A according to the determination result.
Proceed to any one of steps 18 to A24. Step A18 is executed when the judgment result is "forward", and the LCD 15 displays "
"Forward" and "Recognize" are displayed, and a signal 1 corresponding to "Forward" is given to the motor drive circuit 32. Also,
Step A19 is executed when the judgment result is "right",
"Right" and "recognition" are displayed on the LCD 15, and a signal i corresponding to "right" is given to the motor drive circuit 32. Step A20 is executed when the determination result is "left", and displays "left" and "recognized" on the LCD 15 and sends a signal i corresponding to "left" to the motor drive circuit 32.
give. Step A21 is executed when the determination result is "reverse", and displays "reverse" and "recognition" on the LCD 15, and provides the motor drive circuit 32 with a signal i corresponding to "reverse". In step A22, the judgment result is “
This is executed in the case of "temporary stop", and displays "temporary stop" and "recognition" on the LCD 15, and gives a signal i corresponding to "stop" to the motor drive circuit 32. Step A23 is executed when the determination result is "temporary stop", and
Displaying "stop" and "recognition" on the CD 15, giving a signal i corresponding to "stop" to the motor drive circuit 32, and giving a signal d corresponding to "stop" to the MT logic control circuit 29, and , analog switch 22.
The signals a and b to L CD 1 are set to O''. Step A24 is executed when the judgment result is "repeat".
In addition to displaying "repeat" and "recognition" in 5,
A signal d corresponding to "stop" is sent to the MT logic control circuit 29.
and furthermore, the signal a to the analog switch 22.26
, b is set to 0''.Then, the above steps A18 to A2 are performed.
If the process of Step 2 is completed, the process advances to step A14, and if the process of step A23 is completed, the process waits for the restart key 13 to be operated in step A25, and then returns to step A1.

Further, when the process of step A24 is completed, the process proceeds to step A26, and it is determined which mode is designated by the mode switch 14. If the manual M1 or M2 mode is specified, the process proceeds to step A27, where a signal i corresponding to "stop" is output to the motor drive circuit 32, and then the process proceeds to step A25. After registering seven types of commands by specifying the registration mode and the manual M1 mode as described above, by switching to the recognition mode and inputting the desired commands by voice from the wireless microphone 7, the electronic robot follows the input commands. 1 operates accordingly.

Further, when the recognition rate of voice input becomes poor while manually moving the electronic robot 1 as described above, the registration/recognition changeover switch 11 is switched to the registration mode and the voice is re-registered. That is, when the registration mode is designated by the registration/recognition changeover switch 11, the registration mode is detected in step A15 and the process proceeds to step A28. In this step A28, only "registration" is displayed as a symbol on the LCD 15, and the MT logic control circuit 29
At the same time, a stop command is output to the motor drive circuit 32. Then, in step A29, the amplifier 25
The process returns to step A1 with the MT stop signal from .

Then, the voice input by the user is re-registered in the internal memory of the CPU 24 through the processing from step A1 described above.

On the other hand, when using manual M2 or program P mode, operate the MT control key 16 to input the above seven types of commands to the command registration area IE of the cassette tape 40 as shown in FIG. 3(a). Memorize it in advance. Further, when using the mode of the program P, as shown in FIG. I'll keep it. When the electronic robot 1 is to be operated manually, the mode switch 14 is used to specify manual M2, and when the electronic robot 1 is to be operated according to a preset program, the mode of the program P is specified using the mode switch 14. If the mode of manual M2 or program P is specified by the mode switch 14, the specified mode is determined in step A1, and the process proceeds to step A31.

In this step A31, the signals a and b sent from the CPU 24 to the analog switches 22 and 26 are set to "O", and
Signal 1SLC corresponding to "stop" to motor drive circuit 32
A signal is sent to the D drive circuit 31 to display "registration" and "forward", a signal d corresponding to "rewind" is output to the MT logic IIJ i11 circuit 29, and the mute counter is also cleared. Then, with the above "rewind" command, M
When T9 performs rewinding and returns to the starting position, an MT stop signal j is sent to the CPU 24 via the amplifier 25. The CPU 24 detects the MT stop signal j in step A32, proceeds to step A33, outputs the signal d corresponding to "play" to the MT logic control circuit 29, and stops the signal to the analog switch 26. 1". In this state, as shown in step A34, the reproduction signal of MT9 is output to amplifier 25 and analog switch 2.
The system waits until voice input C is received from the preprocessing circuit 23 via G. When voice input is detected in step A34, the process proceeds to step A35, where the registered voice data is compressed and stored in the internal memory. Also, at this time, L CD
15 displays only "registration" or "recognition". Then, in step A36, the content of the mute counter is incremented by "+1", and it is determined whether the count value has reached "7" or not.

If the count value has not reached r7J, step A3
Proceed to step 7 and display the next symbol "Right" on LCD 15.
Return to step A34. Thereafter, the same process is repeated, and the seven types of instructions in the instruction registration area IE are sequentially stored in the internal memory. When the count value of the mute counter reaches "7", the process advances from step A36 to step A38, and the mode switch 14 Program P mode and manual M
It is determined which of the two modes is specified, and if it is the program P mode, the process immediately proceeds to step A12.
If manual M2 mode is specified, step A
Proceed to step 39. In this step A39, the signal d corresponding to "stop" is given to the MT logic control circuit 29, the signal a to the analog switch 22 is set to 1", and the analog switch 26
Set the signal to “OIT” and then repeat step A1 above.
Proceed to step 2. From this step A12 onwards, the same processing as in the manual-to-manual 1 mode is performed, but in the program P mode, the program area PE
The playback signal of the program command passes through the amplifier 25, the analog switch 26, and the preprocessing circuit 23, and is sent to the CP as an audio input.
In the manual M2 mode, commands input from the wireless microphone 1 are sent to the CPU as audio input.
Enter 24. If "repeat" is commanded in program P mode, the process proceeds from step A24 to step A41 via step A26. In this step A41,
A signal d corresponding to "rewind" is output to the MT logic control circuit 29. Then, in step A42, it is determined whether there is a mute interval longer than a predetermined time, and when the mute interval is detected, the process proceeds to step A43, where the content of the mute counter is set to "-1".

Briefly, in this step A43, it is determined whether the contents of the mute counter match "7" or not, and if they do not match, the process returns to step A42 to continue the mute interval detection operation. Then, when it is determined in step A43 that the content of the mute counter matches "A",
Proceeding to step A44, the M7o sick control circuit 29 says “
At the same time, the signal corresponding to "PLAY" is output, and the signal to the analog switch 26 is set to "1", and then the process returns to step AI2.

Thereafter, similar operations are repeated, and in the mode of manual M2, the operation of the electronic robot 1 is controlled according to commands input by voice from the user, and in the mode of program P, the electronic robot 1 is controlled according to voice commands read from MT9. 1 is controlled.
