Abstract

PURPOSE:To prevent the erroneous recognition of a voice due to din, noise, etc. from the outside, by inhibiting the voice recognition in accordance with the output state of a signal indicating the operation state of a device to be controlled or its peripheral device. CONSTITUTION:When a power switch is turned on, a controlling circuit 50 discriminates whether switches 191-193 are closed or not. That is, the circuit 50 discriminates whether a window 100 is opened or not, whether a door is opened or not, and whether a shift lever is set to the position of a back gear or not in accordance with states of switches 191-193. If any of switches 191-193 is closed, an input break switch 20 is opened to inhibit a voice input signal from being given from a microphone 17 to a voice recognizing circuit 60. If switches 191-193 are opened, the circuit 50 gives a control signal for making the switch 20 to the switch 20. Thus, the switch 20 is closed, and the microphone 17 and the circuit 60 are connected.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a voice input control device, and more particularly to a voice input control device that recognizes input voice and controls various controlled devices.

For example, when a driver of a car or the like operates in-vehicle equipment such as opening/closing a radio window or blinking a lamp inside the car, this is done manually. However, in order for a driver to operate a radio or the like while driving a car, it is often necessary to shift the driver's line of sight from the front to the control panel of the device, which can lead to distracted driving and is extremely dangerous. In addition, electronic on-board calculators for drivers have recently been put into practical use;
It was nearly impossible to operate such an electronic desktop calculator while driving. Similar problems also occur when opening/closing windows or operating other in-vehicle devices.

Therefore, without the need for manual operation, the driver can make the &/II sound as if by pronouncing a voice.
A device that controls various controlled devices based on the results can be considered. However, in such devices, for example, if the window of the skewer is open and noise from the outside is mixed in, the voice pronounced by the driver cannot be accurately recognized and malfunctions may occur. It becomes the cause.

Therefore, the main object of the present invention is to provide an acoustic manual fill-m device that can reduce manual operations and prevent errors in tooth angle recognition due to external noise.

According to the present invention, a signal indicating the operating state of the controlled device or its peripheral equipment, such as a car window, is outputted, and when this signal is outputted, an audio input means is outputted. If the peripheral device is in any other operating state, for example when the window is closed, the voice recognition means is activated and the voice recognition means is activated based on the recognition result. It is configured to control controlled equipment.

The 111 circuit uses a conventionally known channel filter, and its configuration and operation will be briefly described below. An audio signal input from the microphone 17 shown in FIG. 4 is amplified by an amplifier 601 and then applied to a pre-emphasis circuit 602.

The pre-emphasis circuit 602 is a filter having a characteristic of about 6 dB10 ct that passes only the low and low 300 to 5 kHz band components of the input audio signal. The audio signal that has passed through the pre-emphasis circuit 602 is given to band pass filters (BPF) 611 to 641. These bandpass filters 611 to 64
1 passes only the audio signal of a predetermined band component and supplies it to the superior stage rectifier circuits 612 to 642.

The rectifier circuits 612 to 642 rectify the output signals of the band pass filters 611 to 641, respectively, and convert them into DC voltages. High-frequency components are removed from the rectified DC current Lt4 by 0-pass filters (LPFs) 613 to 643, and each of the high-frequency components is applied to a multiplexer 603. Further, a trigger signal is output from the low-pass noise filters 13 to 643, and is applied to the trigger circuit 604.

When audio is input from the microphone 17, the audio input signal is amplified ll601. The signals are sequentially applied to a pre-enrichment system 602, bandpass filters 611 to 641° rectifier circuits 612 to 642, and low pass filters 613 to 643. Then, when a signal is given to the trigger circuit 604 from the low-pass filters 613 to 643,
Trigger circuit 604 provides an interrupt signal to CPU 605.

The CPU 605 constantly determines whether a trigger signal is input from the trigger circuit 604 or not. (i.e. CPU
605 always checks whether or not audio is input, and when an interrupt signal is input, it stores analysis parameters in RAM at the time when audio seems to have disappeared.

The radio control circuit 80 includes an input port 81, a CPU 82, a memory 83, and an output port 84. The input port 81 receives Il]IIl data outputted from the output port 54 of the control circuit 50 shown in the fifth tgl and supplies it to the CPU 82. A transfer timing signal is given to the CP LJ 82 from the transfer timing generator 55 of the control circuit 50 as an interrupt signal. Programs necessary for the CPU 82 to control the radio 110 are stored in the memory 83 in advance. CPL182 is control data is Rashi A11

The radio 4110 is, for example, a conventionally known PLL1fd.
A wave number synthesizer-type electronic radio is used.

In such a radio 110, the receiving frequency is determined by storing a signal corresponding to the receiving frequency in the register 111.

That is, a signal corresponding to the reception frequency of register 111 is given to tuning circuit 112. The tuning circuit 112 tunes the frequency corresponding to the manually inputted signal and provides the received signal to the detection circuit 113. Detection circuit 113 detects the received signal and supplies it to attenuator 114 . Attenuator 1
14 is supplied with a volume switching signal from a radio control circuit 80. Then, the attenuator 114 adjusts the level of the output signal from the detection circuit 113 so that the volume signal corresponds to the volume switching signal. The output signal of attenuator 114 is amplified by amplifier 115 and given to speaker 116. Furthermore, the radio 110 is provided with a relay 117 for turning on the power (this relay 117 is connected to the CP
A power-on signal output from LI 82 through output port 84 closes its contacts.

FIG. 19 is a diagram for explaining specific operating sounds of the radio control circuit 80 and the radio 110 shown in the 8th all. Next, specific operations of the radio control circuit 80 and the radio 110 will be described with reference to FIGS. 8 and 1119. The CPU 82 determines whether or not a transfer timing signal is given from the control circuit 50, and reads control data from the input port 81 when an interrupt due to the transfer timing signal occurs. And that l1IIIl
It is determined whether the l data is a power-on command signal, and if it is a power-on command signal, a control signal for closing the contact of the relay 117 is provided via the output port 84.

This activates the contacts of relay 117.

A power supply voltage of 10 V is supplied to the radio 110.

If the control data is not a power-on command signal, the CPLJ 82 determines whether or not it is a frequency switching signal. If the frequency switching is tM%, the data of the receiving frequency corresponding to the frequency switching signal is continuously output from the memory 83 and the C register 11
1, and the write clock signal is also supplied to register 11.
Give to 1. As a result, register 111 reads Cf-1 based on the write clock signal. Then, the tuning circuit 112 receives a signal of a corresponding frequency based on the reception frequency data stored in the register 111.

Furthermore, if the control data is not a frequency switching signal, the CPU 82 determines whether the control data is a volume switching signal. If it is a volume switching signal, a volume control signal corresponding to the volume switching signal is given to the attenuator 114 via the output port 84.

Accordingly, the tone generator 114 adjusts the level of the output signal of the detection circuit 113 so that the sound corresponds to the input volume control signal.

Figure W410 is a specific block diagram of the lamp blinking circuit 9o shown in Figure 4. This lamp blinking circuit 90 includes a latch circuit 91 and a relay 92. The latch circuit 91 is supplied with a lamp blinking signal and a transfer timing signal. Then, the launch circuit 91 stores the lamp lighting signal based on the transfer timing signal and closes the contact of the relay 92.

Then, the power supply voltage +V is input to the lamp 120, and the run 1112 is turned on.

111A and 118 are flowcharts C for explaining the specific operation of one embodiment of the present invention.

Next, with reference to FIGS. 1 to 118, the specific operation of one embodiment of the present invention will be described. First, when the power switch (not shown) of the voice input control device is turned on, the CPLI 52 and memory 5 included in the control circuit 50 are turned on.
3 are each initialized. And in this state, the special machine state becomes loud. At this point, the CPU 52 switches the switch 191.1
It is determined whether or not 926 and 193 are closed.

That is, it is determined whether the τ window 100 is open or not based on whether the switch 191 is closed or not, and it is determined whether #101 is open or not based on whether the switch 192 is closed or not. Then, it is determined whether the gear lever 9 is put into the reverse gear position based on whether the switch 93 is closed or not.
When the window 100 or #101 is opened or when the shift lever 9 is placed in the reverse gear position, the input cutoff switch 20 is used to prohibit the audio input signal from the microphone 17 from being given to the audio recognition circuit 60. do. Conversely, when the windows 100 and #101 are closed and the shift lever 9 is in a position other than reverse gear, the CPLI 52 sends a control signal to turn on the input cutoff switch 20 via the output port 54. It is applied to the input cutoff switch 20. This is it.) [, person hil! The disconnect switch 20 is closed, and the macro/J--n 17 and the voice recognition circuit 6o are connected. And the CPU 52 is a voice! ! It is possible to receive a transfer trigger signal from the open circuit.

In operation #11, after operating the switch 19f, a voice necessary for operating the controlled device m is emitted into the microphone 17. That is, necessary sounds are emitted for opening and closing the window 1oo, turning on the power of the radio No. 110, switching the frequency or switching the frequency, and lighting the lamp 120. These voices are transmitted by microphone 17 to U*
fi 14, and this electrical signal is applied to the voice recognition circuit 60 via the input cutoff switch 20. The recognition circuit 60 recognizes the human voice as explained in FIG. In the control circuit 50, the human boat 51
reads the free idim data from the speech recognition circuit 60. Then, the CPU 52 determines vIf in the voice recognition data received by the person/J/Jζ-to 51.

In other words, CPIJ52 is voice recognition! lf-ta is the 1st

A transfer timing signal is generated from the generator 5b. These control data and transfer timing signal are given to the Uzi 4vJ1111 circuit 80. Therefore, the radio control circuit 80 controls the radio 110 based on the input control data. That is, the radio control circuit 80 controls the radio 110 based on the input control data. , radio) control circuit 80, as explained in FIG. The data is stored, and if the signal is switched, the attenuator 114 controls the switching of the total amount.

Similarly, if the voice is a command to open/close the window 100,
ilJ control data is given to the voice response circuit 30, and its f-
A voice corresponding to evening is emitted from a speaker 18. Then, it outputs control data corresponding to opening and closing of the window 100, and also specifies an address and causes the transfer timing generator 55 to generate a transfer timing signal. Then, the window opening/closing circuit 70 stores the control data in the latch circuit 71 as explained above in FIG.
Either contact 721 or 722 of No. 2 is closed. This controls the opening and closing of 1100.

Furthermore, if the voice recognition data is a command to blink the lamp (-), the i-control data is similarly given to the voice response circuit 30, and the corresponding voice is emitted from the -power 18.
The PU 52 outputs control data corresponding to the blinking of the lamp 120, specifies an address, and causes the transfer timing generator 55 to output a transfer timing signal. depending on,
The lamp blinking circuit 90 shown in FIG. 10 stores control data in a latch circuit 91 to close or open the contacts of a relay 92. Accordingly, the automatic medium-sized lamp 120 is turned on or off.

Incidentally, if the sound recognition data indicates that speech recognition is impossible, that is, if it is rejected, data indicating this is provided to the acoustic response circuit 30.

Respond<,! One response circuit 30 connects mhl from the speaker 18.

As described above, according to this embodiment, voice recognition by the voice recognition circuit 60 is enabled only when the windows 100aj and 101 are closed and the shift lever 9 is placed in a position other than reverse gear. Therefore, it is possible to prevent the voice pronounced by the driver 11 from being accurately recognized due to external noise and other noises. When you want to open/close the radio 100, turn on the radio 110, or blink the lamp 120, the voice necessary for each control is sent to the microphone 17 (no manual operation is required other than just sounding the sound). In addition, since a sound corresponding to the sound produced is emitted from the speaker 18, it is difficult to check whether the input sound has been accurately recognized.
Therefore, the driver '11 can see the driver's seat 71 without turning his eyes away from the front.
By opening and closing the motors 110 and 1100, it is possible to improve the eye movement rate for safe operation.

The contents of the register may be cleared when the control of the $131Ii device is completed.

In addition, in the above explanation, the present invention is applied to the case where the invention is automatically * i, :, to control the mounted controlled equipment (although it is not limited to this, and it is not limited to this), for example, when controlling various controlled equipment indoors. The present invention can also be applied to such cases.

As described above, according to the present invention, the IIJ 111m
111 or was input according to the operating status of its peripheral equipment! It is possible to prohibit the recognition operation of it- or to control the controlled device based on the recognition result.

ShiIkokka-C1 This function is used to prevent the pronounced @轡 from being accurately recognized due to external noise or noise.
