Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a voice recognition toy that identifies voices and performs actions corresponding to the voices.

[Prior Art] Conventionally, voice recognition toys have been known that, when a voice command is sent using words that mean a specific action, the toy performs the action corresponding to the command. This system is equipped with a microcomputer as a means of actually identifying audio signals, and has a memory section that stores (registers) sounds corresponding to several actions as reference sounds in advance. It compares each pattern of the reference sound and the reference sound to determine whether they match or do not match. If they match, a signal corresponding to the reference sound is sent to the drive unit to perform a predetermined operation.

[Problems to be solved by the invention] However, in such voice recognition toys, as the number and types of actions increase, the number of voice commands also increases, and similar voice patterns occur, so it is difficult to recognize the actual voice. The method of comparing all voice patterns in which commands are stored in advance has a problem in that the accuracy of voice identification decreases and it becomes difficult to perform correct actions.

Additionally, when trying to make a voice recognition toy perform an action as described above, if you have forgotten or are unsure of the registered voice command, it may be difficult to activate the toy with a single voice command. So, even if you register a new voice command, the same voice will not always occur, and unless the toy is activated,
I wasn't sure if the voice command was the same as the registered reference voice.

The present invention was developed in view of the above problems, and its first purpose is to provide a voice recognition toy that can reliably identify each voice command and perform correct actions even when the number of types of voice commands increases. It is to be.

Another purpose of the present invention is to enable a voice recognition toy to confirm whether or not a voice command matches a registered voice before the toy performs an action corresponding to the voice command.

Yet another purpose of the present invention is to provide a voice recognition toy with high accuracy in voice recognition by inputting the speaker's voice under the same conditions both during voice registration and subsequent voice recognition. be.

[Means for Solving the Problems] The present invention includes a storage device that registers voice commands corresponding to the motion of a toy as a reference voice, a voice input device that inputs the voice commands, and a voice command input from the voice input device. A voice recognition device that compares a voice command with a reference voice registered in the storage device and outputs an operation signal corresponding to the reference voice when it is determined that the two match, and a voice recognition device that outputs an operation signal corresponding to the reference voice; A voice recognition toy that has a drive unit that performs a predetermined movement according to the sound, a voice registration switch for registering a reference voice, and a group that classifies the movements of the toy into two or more groups and specifies the group to which each movement belongs. It is equipped with a designated switch and a display device that displays the match/mismatch between the input voice command and the reference voice, and when registering the voice, the reference voice is stored in the storage area according to the group to which the action corresponding to the operated voice registration switch belongs. When the voice is stored and a voice command is input by operating the voice registration switch again, the system determines whether the voice command matches or mismatches the registered reference voice and displays the result. In order to perform an action, if you specify the group to which the action belongs using the group specification switch and input a voice command corresponding to the action, the match/mismatch between the voice command and the reference voice within the specified group will be displayed. It is characterized by determining.

In an embodiment of the present invention, the means for inputting audio includes a transmitter that transmits an audio signal corresponding to a voice command and a frequency signal corresponding to a group designated by a group designation switch; It consists of a receiver that receives signals and sends them to a speech recognition device.

Furthermore, in an embodiment, a recording device is provided for recording a voice command and a signal specifying a group in response to an output signal from the voice recognition device, or for reading the recorded contents, and a tape recorder is used as a specific means for this. The drive of the recording tape is controlled by the output signal from the voice recognition device.

[Function] When registering a voice, the operator first operates the voice registration switch corresponding to the motion he wants to register, and then inputs a voice command to make the toy perform that motion using the voice input device.The voice command is then , is stored as a reference voice in the group to which the action corresponding to the operated voice registration switch belongs. after that,
When the user operates the voice registration switch again to input a voice command, the voice recognition device determines whether the voice command matches or does not match the registered reference voice, and the result is displayed on the display device. This allows the operator to confirm the voice command for performing a predetermined action.

When you want a toy to perform a desired action, specify the group to which each action belongs using the group designation switch, and then input a voice command.The voice recognition device will then match the voice input with the reference voice within the specified group. A match/mismatch is determined, and if a match is found, an operation signal corresponding to the voice is output. In response, the drive part of the toy is activated,
Perform a predetermined action.

ACTION switch 51 ...2500Hz TAPE switch 52 ...2000Hz TALK/ON switch 53 ...1500Hz TALK/OFF switch 54 ...1000Hz (2) Circuit inside the toy body Next, referring to Fig. 10, the toy body An electronic circuit including a voice recognition device is housed inside. This is a component on the input side.
It includes a receiving section 71 including an antenna for receiving signals such as audio transmitted from the transmitter 50, and a circuit 75 for waveform shaping the signal passed from the receiving section through a band filter 72, a changeover switch 73, and an amplifier 74. There is. The changeover switch 73 is switched in conjunction with the mode changeover switch 34 described above, and its operation will be described later. The signal from the waveform shaping circuit 75 is input to a microprocessor (CPU) 76 that performs voice recognition and other operations.
Connected to this CPU 76 are a switch circuit 77 including the aforementioned voice registration switches S1 to S12, and a memory (RAM) 78 that stores the pattern of the voice signal input at the time of voice registration.

On the output side of the CPU 76, there is a drive circuit 81 for the light emitter 43 that lights up the robot's eyes, and a CPU 76.
76 or the operation switch circuit 82 of the tape recorder 21 (including the aforementioned switches 23 to 27)

A motor drive circuit 86 that drives the traveling motors 12L and 12R described above in response to an output signal from the CPU 76, and a light emitting body L1 of the voice registration switch section 6 that drives the aforementioned traveling motors 12L and 12R in accordance with an output signal from the CPU 76.
and a display unit 87 that lights up L2.

In addition, the output of the amplifier 74 on the input side is not only applied to the CPU 76 as described above, but also supplied to an amplifier circuit 89 via an electronic switch 88 that is turned on and off by the output of the CPU 76, and lights up the mouth of the robot. The drive circuit 90 of the light emitter 44 and the speaker 39 are driven. Further, the output of the amplifier 74 is also supplied to a drive circuit 91 for a reception display light emitting body 45 attached to the head of the toy 1. electronic switch 88
In case of wireless microphone operation described below, CPU
It is turned on by the output of 76.

On the other hand, the recording microphone 35 disposed in front of the toy 1 is connected to the recording/playback control section 93 of the tape recorder 21 via a changeover switch 92 that is interlocked with the mode changeover switch 34 described above. Based on the output from the control section 93, recording and erasing are performed on the tape via a recording head 94 and an erasing head 95, respectively.

A specific configuration of the above circuit is shown in FIG.

In the figure, the motor drive circuit 86 includes a drive circuit for the left wheel drive motor 12L and a drive circuit for the right wheel drive motor 12R. Each drive circuit rotates each motor 12L, 12R in the normal direction (rotates in the direction in which the robot toy 1 moves forward) when one of the two input signals is "1" and the other is output "0", and the two input signals When is opposite to the above, each motor is configured to reverse (rotate in the backward direction).
Such motor drive circuits are known.

The drive unit 85 of the tape recorder includes a motor 85a that drives the reel, a motor 85b that rotates the capstan in a certain direction, a solenoid 85c that switches the position and engagement of the rotation transmission element,
This is a known drive mechanism consisting of a tape playback and stop detection mechanism 85d using a magnet and a Hall element.

Although not shown, a timer device for driving a time display section 31 using a liquid crystal is housed within the toy body. This is comprised of a known clock LSI that has functions such as displaying the time in response to the input of each switch in the switch group 32, or emitting a predetermined signal or alarm sound at an arbitrarily set time.

Here, to explain the voice recognition operation using the above-mentioned electronic circuit, when registering a voice, first switch S1 to S12 corresponding to the voice to be registered.
Press to turn it on. For example, if the user wants the toy to perform a forward movement by giving a voice command of ``go'', the user presses the switch S1. As a result, the light emitting body L1 (FIG. 4) of the voice registration switch section 6 starts blinking. In this state, when you press the MIC button 58 of the transmitter 50 and issue a voice command to the microphone 57, the voice signal sent from the transmitting antenna 59 is input to the receiver 71 of the toy 1, and finally
The CPU 76 stores it in the RAM 78 as a reference voice. When the storage of the reference voice is completed, the light emitter L1 becomes completely lit to indicate that the registration has been completed.

By operating each of the switches S1 to S2 in this manner and storing voice commands for performing the above-mentioned 12 types of operations in the RAM 78 as reference voices, voice registration is temporarily completed.

According to the present invention, during voice registration, voice commands for performing each action are classified and stored for each group to which each action belongs. This grouping is done when you press the voice registration switch S1 to S12.
The CPU 76 identifies the group corresponding to the pressed switch and selects the registered voice input after that.
This is accomplished by storing in a predetermined storage block within RAM 78.

After registering the voice as described above, by inputting a voice command using the same procedure, it is possible to confirm whether or not the input voice matches the registered voice without waiting for the toy to move. That is, when the switches S1 to S12 are pressed again after the voice has been registered, the CPU 76 causes the light emitting body L1 of the voice registration display section to blink. Next, when an audio signal is sent from the transmitter 50,
The CPU 76 compares the audio signal with the registered audio, and if the two match, it outputs a signal to turn on the light emitter L1, and if they do not match, it keeps the light emitter L1 blinking. This allows the operator to confirm the voice command that matches the registered voice and reliably operate the toy.

(3) Operation The robot toy 1 configured as described above operates as follows.

(a) Running and eye lighting operations First, the mode selector switch 34 on the front of the toy body is set to the operation position (RECG) that includes voice recognition, as shown in FIG. As a result, the changeover switches 73 and 92 of the internal circuit are switched to the eleventh switch.
As shown in the figure, it is connected to lines that send signals from the receiving section 71 and the microphone 35 to the CPU 76 and the recording/playback control section 93, respectively.

Next, the ACTION switch 51 of the transmitter 50
When pressed, a 2500Hz signal is sent out from the antenna 59. When the CPU 76 of the toy 1 receives this frequency signal, it detects the aforementioned group A. After that, when a voice command is sent from the transmitter 50 to make the robot perform one of the seven types of operations in this group, the CPU 76 transmits the input voice signal to the group A in the RAM 78.
It compares it with seven reference sound patterns stored in memory blocks corresponding to the reference sound patterns, and if it matches any of the reference patterns, it outputs a predetermined signal to the output terminal corresponding to that reference sound.

For example, in the case of running operation, the CPU 76
Signals corresponding to the recognized voice command are output to four output ports connected to the motor drive circuit 86. As a result, the left and right motors 12L, 12R
rotates forward, reverses, or stops, causing the toy 1 to move forward, backward, change direction, or stop.

In addition, in the case of eye lighting operation, the CPU 76
transmits a signal corresponding to the recognized voice command to the light emitter 4.
It outputs to the output port connected to the drive circuit 81 of No. 3. Thereby, the light emitter 43 of the eye is turned on or off.

(b) Tape recorder operation The mode changeover switch 43 is set to the same position as above (RECG).

As mentioned above, when the TAPE switch 52 of the transmitter 50 is pressed, a 2000 Hz signal is transmitted from the antenna 59. When the CPU 76 of the toy 1 receives this frequency signal, it detects the aforementioned group B. Thereafter, a voice command to perform one of the five actions in this group is sent to the transmitter 50.
, the CPU 76 compares the input audio signal with five types of standard audio patterns stored in the memory block corresponding to group B in the RAM 78, and if it matches any of the standard patterns, , outputs a signal to the output terminal corresponding to the recognized voice command among the five output terminals connected to the control unit 83. Note that these output terminals are controlled by a control section 83 via an electronic switch 100 that is turned on and off by an input signal.

For example, for rewinding (REW), the CPU
76 outputs a signal corresponding to the perceived voice command to the rewind output terminal. This turns on the electronic switch 100, and the control unit 83 detects this switch input and sends a signal to the drive circuit 84 to drive the motor of the tape recorder drive unit 85 in the tape rewinding direction.

In the case of recording (REC), the output from the CPU 76 is applied to an electronic switch directly connected to the control section 83 and an electronic switch connected to the control section 83 via the recording inhibit tape detection switch 101. The control unit 83 controls these two electronic switches 100 and the recording prohibition tape detection switch 1.
A drive signal is output when all 01 are turned on.
The recording-inhibited tape detection switch 101 is not turned on when a recording-inhibited tape is loaded, and even if a recording command is output from the CPU 76, the control unit 83 does not detect this.

If recording is to be performed manually without depending on a voice command, the REC switch 23 and RLAY switch 25 may be pressed together in the same way as in normal tape recorder operation. Since the REC switch 23 is connected to the control unit 83 via the record-inhibited tape detection switch 101, the control unit 83 does not output a REC signal when a record-inhibited tape is loaded.

After the tape is started by a recording command, the voice to be recorded is inputted from the microphone 35 of the toy body.

Recording (REC) and playback (PLAY) of the above
In this case, in addition to the drive signal applied to the drive circuit 84, the control unit 83 sends a signal applied to the electronic switch in the recording/playback control unit 93 (in FIG.
(represented by REC and PLAY). Especially in the case of playback, the electronic switch 103 connecting the recording/playback control section 93 and the amplifier circuit 89 is
The speaker 3 is turned on by the PLAY signal, and the recording content taken out from the tape by the head 94 is sent from the control section 93 to the amplifier circuit 89.
9, and the light emitter 44 in the robot's mouth blinks.

In addition to the drive signals described above, the control unit 83 also controls the light emitting body 23a on the front surface of the tape recorder,
A signal for lighting up 24a, 25a and 26a is output.

(c) Wireless microphone The mode selector switch 34 on the toy body is set to the same position (RECG) as above.

As mentioned above, when the TALK/ON button 53 of the transmitter 50 is pressed, a 1500 Hz signal is transmitted from the antenna 59. When the CPU 76 receives this frequency signal, it thereafter cancels the above-mentioned and voice recognition states. This is to prevent the voice sent from the transmitter 50 from being confused with the voice command described above. At the same time, the CPU 76 outputs a signal to turn on the electronic switch 88 to an output terminal connected to the electronic switch 88.
Therefore, when speaking into the microphone 57 of the transmitter 50, the audio signal received by the receiver 71 is sent from the amplifier 74 through the electronic switch 88 to the amplifier circuit 89, and is output as audio from the speaker 39. . At this time, the robot's mouth 42 blinks.

When the use of the wireless microphone described above is finished, when the TALK/OFF button 54 of the transmitter 50 is pressed, a frequency signal of 1000 Hz is transmitted from the antenna 59. When the CPU 76 receives this signal, it stops outputting to the terminal connected to the electronic switch 88 and turns off the electronic switch 88. Therefore, even if audio is transmitted from the transmitter 50 from now on, the speaker 39 and the light emitter 44 will not operate. This operation of turning off the wireless microphone is necessary to perform the voice recognition operation described above next.

(d) Recording (MEMORY) operation Mode changeover switch 34 of robot toy 1
is set at the recording operation position (MEMO) shown in FIG. As a result, the internal circuit changeover switches 73 and 92 are respectively shown in FIG.
Switched to MEMO position. In this case, the changeover switch 73 is connected to the line that sends the signals from the receiver 71 to the CPU 76, as in the above RECG position, but the changeover switch 92 is connected to the line that sends the signals from the receiver 71 to the receiver 71 instead of the signal from the microphone 35.
It is connected to a line that sends signals from to the recording/playback control section 93.

Next, after loading the cassette tape, the user presses the TAPE button 52 on the transmitter 50 and inputs a recording command into the microphone 57 of the transmitter. As a result, the cassette tape is driven as explained in (b) above, so the operation you want to memorize is transferred to the transmitter 5.
Send from 0. That is, press the ACTION button 51 on the transmitter.

The group A running and eye lighting commands are input into the microphone 57 of the transmitter.

Press the TALK/ON button 53 on the transmitter.

A voice is input into the microphone 57 of the transmitter.

When you have finished transmitting audio, press TALK/ on the transmitter.
Press the OFF button 54.

After the above memory operation transmission is completed, the transmitter 50
Press the TAPE button 52 and input a rewind command into the microphone 57. As a result, the cassette tape is set to its initial starting state.

(e) Recording/playback (REPEAT) Mode switching switch 34 of robot toy 1
is set at the playback operation position (REPT) shown in FIG. As a result, the internal circuit changeover switches 73 and 92 are respectively switched to the REPT position shown in FIG. In this case, selector switch 7
3 is connected to a line that sends a signal from the recording/playback control section 93 to the CPU 76 rather than from the receiving section 71, while the changeover switch 92 is switched to a position where it is not connected to either the microphone 35 or the receiver 71. .

Next, attach the tape recorded in (d) above, and press the PLAY button 25 on the front of the tape recorder.
Press. As a result, the recording/playback control unit 93 inputs the stored content retrieved by the head 94 to the CPU 76, and the CPU 76 performs voice recognition to cause the toy to perform actions such as running. At the same time, the output of the recording/playback control section 93 is sent to the amplifier circuit 89 via the electronic switch 103, which is turned on by the PLAY signal, to drive the speaker 39 and the light emitter 44 of the robot's mouth.

(f) Timer operation Switch group 3 on the front of the body of the robot toy 1
2, set the desired time in advance, and then turn the power switch 33 on the right side.
Set to TIMER position.

If the recorded contents of the tape are to be played back as is, the mode switching switch 34 is set to the RCOG position. At the set time, the timer device will
Since the PLAY signal is output, the tape starts spinning and normal playback begins.

On the other hand, when performing the recording/reproduction described in (e) above, the mode changeover switch 34 is set to the REPT position.
When the set time comes, the timer device outputs a PLAY signal, so the tape starts spinning and toy 1
REPEAT operation can be performed.

Although the embodiments have been described above, the present invention is not limited thereto. For example, in the above embodiment, the sound is sent from a wirelessly controlled transmitter, but the sound may be registered by directly inputting the sound to the microphone of the toy.

[Effects of the invention] As described above, according to the invention, when registering a voice, the reference voice is stored in the storage area of the group to which the motion to be registered belongs, and the voice command is input by operating the voice registration switch again. It determines the match/mismatch between the voice command and the registered reference voice and displays the result, so the reference voice can be reliably registered, and the voice command that causes the toy to perform a predetermined action is the registered reference voice. It is possible to check whether the toy matches or not without waiting for the toy's movement.

In addition, by specifying the group to which each action belongs using the group designation switch and then inputting a voice command, it is possible to determine whether the voice input matches the reference voice within the specified group, so the reference voice can be registered. In addition, the processing procedures of the electronic device necessary to determine whether voice commands match or do not match are simplified, and the software for voice recognition and toy motion control is also simply configured, reducing product costs. can be achieved.

As described above, a voice recognition toy is proposed that has a high recognition rate and operates reliably even when the number of types of voice-based motions increases.
