Abstract

PURPOSE:To attain ease of dialing operation by decoding a microphone output by a voice recognition circuit so as to control the operation of a communication means in response to the said output, while discriminating the end of input of a dial number thereby inactivating the voice recognition circuit. CONSTITUTION:A signal from a microphone 29 is identified by a voice recognizing circuit 27. The circuit 27 gives a code signal through a line 30 when a voice coincident with the content registered in advance for voice recognition is uttered. The code signal is given to a processing circuit 23 thereby allowing a control signal from a line 35 to be given to a switching transistor of a keyboard 24 and each numeral of dialing by voice is inputted to a car telephone set 21. In this case, since the voice recognition circuit 27 is inactivated after the input of the dialing number is finished, no malfunction is caused even if a numeral is mixed during talking.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention is directed to a telephone such as a car phone or a personal radio device, which uses an input dial signal to identify a destination corresponding to the dial signal and at least transmit or receive data in a communication frequency band. The present invention relates to a device that performs one-year noise using the voice of a communication means that performs either one of the two operations.

BACKGROUND ART FIG. 1 is a simplified perspective view of a conventional car telephone device 1 mounted on a car. The car telephone device 1 is connected to an antenna 2 and can dial 75 by manually operating keys on a keyboard 4 provided in the handset 3. This hand centrifuge 3 is equipped with a speaker 5 and a microphone 6. In such a device.

Operating the keyboard 4 of the phone set 3 while driving is not desirable from the perspective of safe driving, and the driver of the car is not allowed to use the car phone while driving. .

FIG. 2 shows another prior art. A control device 875 called a so-called /% free phone has been proposed.

A speaker 5 and a microphone 6 are individually connected to the control device 8, and a panel 9 of the flj control device 8 is provided with a keyboard 10. Such prior art also requires the keyboard 10 to be used for dialing.

Therefore, it cannot be said to be preferable from the standpoint of safe driving.

Purpose The purpose of the present invention is to provide an improved voice dialing system that makes it possible to easily perform so-called dialing operations in which numerical values are input to call a communication partner or specify a communication frequency band. The purpose is to provide equipment.

Embodiment FIG. 3 is a block diagram of an embodiment of the present invention. An antenna 22 is connected to the car telephone device 21,
It is connected to a processing circuit 23 realized by a microcomputer or the like. The processing circuit 23 includes a car telephone device 2.
A keyboard 24 is connected for all dialing operations and control operations. In the keyboard 24, switches to be suppressed are arranged at intersections between a plurality of lines 25 extending in one direction and a plurality of lines 26 extending in the other direction. For these switches.

Switching transistors are connected in parallel, and a signal equivalent to a signal generated by manual key operation of the keyboard 24 is input to the processing circuit 23 by a transistor control signal from the voice recognition circuit 27 via a line 35. fl in the processing circuit 23, speaker 28 and microphone 29 in the amplifier circuit 3.
6, respectively. The signal from the microphone 29 is input to a voice recognition circuit 271C, where the signal is identified.

The speech recognition circuit 27 is as shown in Table 1.

A code signal is derived from line 30 when a voice matching the content registered in advance for voice recognition is uttered. This code signal is applied to a processing circuit 23 [by means of which a transistor provided in the keyboard 24 is provided with a control signal on line 35 so that each numerical value of the voice dialing is
1 will be input.

FIG. 4 of Table 1 is a perspective view of the seat 31 of an automobile. This seat 3
1, a pillow part 33 for supporting the head is provided on the upper part of the backrest part 32.
will be provided. A pair of speakers 28 are built into the pillow part 33, corresponding to the left and right ears.

A base end of a flexible arm 34 is fixed to the side of the pillow part 33, and a microphone 29 is fixed to the free end of this arm 34. The microphone 29 can be positioned near the driver's mouth by bending and displacing the arm 34.

FIG. 5 is a flowchart for explaining the operation of the embodiment shown in FIGS. 3 and 4.

Moving from step n1 to step n2, the car telephone device 2
1 is activated, and if so, inputs audio from the microphone 29 and transmits it to the conventional handset 3.
A so-called hook signal similar to that obtained when the button is removed (see FIG. 1) is input to the processing circuit 23 via the keyboard 24. If the telephone is not activated, the process moves from step n2 to step n4, and the telephone number is entered by speaking into the microphone 29. When this telephone number has 9 digits, that is, it is a telephone number in the Tokyo area, the process moves to child step nlO, and it is determined whether the first telephone number is "03". If so, the voice recognition circuit 27 identifies the number, and the processing circuit 23 derives a signal corresponding to each digit of the telephone number 9, and derives a signal similar to that obtained by manual key operation. When it is determined in step n9 that the telephone number that has been completely input has 10 digits, the voice recognition circuit 27 also identifies a telephone number outside the Tokyo area, and the processing circuit 231C generates a signal equivalent to the manual key operation of the keyboard 24. is input to the car telephone device 21, and dialing is performed in step n12.

In step n9, when it is determined that the input number is not 10 digits, the Vc broadcasts on the speaker 28 that the input number is incorrect.

In step n5iC, when a voice indicating that the telephone is disabled is input, the voice recognition circuit 27 and the processing circuit 2-3
Accordingly, in step n6, the car telephone device 21 is disabled, the generation of the hook signal is cut off, and the voice recognition circuit 27 is activated. Step n8.n as above
9, the operation of the voice recognition circuit 27 is stopped and disabled after the input of a multi-digit dialing number is completed.

This prevents malfunctions caused by uttering numbers during a call or by entering numbers during a call from the other party.

Effects As described above, according to the present invention, there is no need for manual key operation while driving a car, for example.

This makes it possible to easily operate a so-called dialing device in which numerical values are input to call the other party, specify a communication frequency band, etc.

Favorable effects can also be obtained from the standpoint of continuing safe driving.
