JPH0234078A - Telephone set with originating call control device - Google Patents

Abstract

PURPOSE:To attain ease of originating call control by devising the device such that the originating call control is released only when a person registering its voice utters a registered word and the originating call control is unable to be released even if other person utters the same word. CONSTITUTION:When a caller utters a key word to a microphone 29 at first in the case of dialing by this telephone set, its voice signal is A/D-converted and inputted to a voice recognition device 32. The device 32 compares the inputted voice with a voice stored and registered in a data storage device 33, when the word and the voice tone are the same as those registered in the device 33, a signal representing dialing OK is outputted to a dialing inhibit switch 27. Then the switch 27 is turned ON to connect a dialer 26 and a dial transmission circuit 28 and a display device 35 informs it that the dialing is possible. When the device 32 recognizes that the inputted voice and the registered voice differ, the switch 27 is left turned OFF and no dial number is able to be dialed.

, through a telephone communication circuit 19.

(Problems to be Solved by the Invention) By the way, with the above-mentioned telephone equipped with a call restriction device, there is a problem that if the registration number is short, it is easy for others to know, and conversely, if it is made long, the registrant himself/herself may not be able to know the registration number. There was a problem that not only was it difficult to remember, but it was also easy to forget the registration number.

Furthermore, in an emergency, the registrant may be in a hurry and make a mistake or forget the input information, which becomes a serious problem when a fire or robbery occurs in a general store or the like.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a telephone equipped with an easy and safe call restriction device.

[Structure of the invention]

(Means for Solving the Problems) The present invention has been made to solve the above problems, and includes a dialing device, a storage device for storing the voice of a specific person, and a voice input from a specific person. An identification device that identifies whether the voice is the same as the voice stored in the storage device, and a dialing device is turned on when the voice is identified as the same voice by this recognition device, and a dialing device is turned on when the voice is identified as a different voice. The configuration includes a switch that sets the transmitting device to an oFp state.

(Function) The present invention includes a dialing device, a storage device that stores the voice of a specific person, and a device that identifies whether or not the input voice is the same as the voice stored in the storage device. The device is equipped with an identification device for identifying voices, and a switch that turns the dialing device on when the same voice is identified by the identification device, and turns the dialing device off when it is identified as a different voice. The restriction on outgoing calls is lifted only when the registered person utters the registered words, and even if another person speaks the same words, the restriction on outgoing calls cannot be lifted because the voice is different.

Therefore, it is only necessary to register short words, and the registered words can be easily remembered and can be prevented from being forgotten, and even in an emergency, the registered words can be easily remembered.

Therefore, it is possible to perform transmission regulation easily and with high reliability.

(Example) Hereinafter, an example of the present invention will be described with reference to FIG.

In this figure, symbols Ll and L2 indicate office line connection terminals. A diode bridge 21 is connected to the office line connection terminals LL and L2, and a communication circuit 23 is connected to the diode bridge 21 via an internal communication line 22. A handset 24 is connected to the telephone communication circuit 23, and the voice signal of the speaker is transmitted to the outside through the diode ring 21 and the office line connection terminals L1 and L2.

Further, the main body of the telephone is provided with a keypad 25, and a dial transmitter 26 is connected to the keypad 25, which transmits a pulse corresponding to a telephone number. This dial transmitter 26 includes a dial prohibition switch 2.

A dial sending circuit 28 is connected to 7. This dial sending circuit 28 is provided in the internal communication line 22 between the diode bridge 21 and the communication circuit 23,
In response to a pulse from the dial transmitter 26, the internal path line 22 is cut off and a dial signal is sent out.

On the other hand, this telephone is equipped with a microphone 29 and a dial prohibition switch 2.
7, an amplifier 30, an analog-to-digital converter (hereinafter referred to as an A/D converter) 31, and a voice recognition device 32 are connected in this order. The voice recognition device includes a data storage device 33, a voice registration switch 34, and a display 35.
is connected.

The microphone 29 is for inputting registered audio, and the A/D converter 31 is configured to convert an analog audio signal input from the microphone 29 via an amplifier 30 into a digital signal. The voice recognition device 32 is configured to store the voice signal from the A/D converter 31 in the data storage device 33 when the voice registration switch 34 is turned on, that is, at the time of voice registration. Further, when the voice registration switch 34 is turned off, that is, during voice recognition, the voice signal from the A/D converter 31 and the registered voice stored in the data storage device 33 are compared. If it is determined that the voices are the same, a signal indicating that the call is OK is output to the dial call prohibition switch 27 and the display 35. The dialing prohibition switch 27 is
The dial transmitter 26 and the dial sending circuit 28 are connected only when a call OK signal is input from the voice recognition device 32, and are shut off otherwise.

Further, the display device 35 lights up or generates a sound only when a call OK signal is input from the voice recognition device 32.
It is designed to display to the user that it is possible to make a call.

The operation of such a telephone will be explained.

To register voice on the telephone, first, turn on the voice registration switch 34, and input the words to be registered as voice from the microphone 29. The input audio is amplified by an amplifier 30 and converted from an analog signal to a digital signal by an A/D converter 31. This digitally converted voice is input to the voice recognition device 32, and the voice signal input to the voice recognition device 32 is stored in the data storage device 33.

Thereafter, the voice registration switch 34 is turned off to complete the registration work.

Next, in order to make a call using the telephone, the caller first speaks a keyword into the microphone 29. Then, the voice signal is similarly A/D converted and input to the voice recognition device 32.

The voice recognition device 32 compares the input voice with the registered voice stored in the data storage device 33, and if the words are the same and the voice is the same, a signal indicating that the call is OK is output to the dial call prohibition switch 27.

When the call OK signal is input manually, the dial call prohibition switch 27 is turned on to connect the dial transmitter 26 and the dial output path 28.

Further, the transmission OK signal is also output to the display 35. When this signal is input, the display 35 lights up or makes a sound to notify the user that dialing is possible.

Thereafter, when the user inputs a dial number from the keypad 25, the dial number is sent out via the dial transmitter 26, the dial sending circuit 28, and the diode bridge 21.

On the other hand, if the voice recognition device 32 recognizes that the input voice and the registered voice are different, the call is OK.
signal is not output. Therefore, the dialing prohibition switch 27 remains OFF, and the dialed number cannot be sent.

In this way, in the above embodiment, the data storage device 33 stores the voice of a specific person, and it is determined whether the input voice is the same as the voice stored in the data storage device 33. Since it has a voice recognition device 32 and a dialing prohibition switch 27 that connects the dialing device 26 to the dialing circuit 28 when the voice recognizing device 32 determines that the voices are the same, the voices can be registered. Only when the person who made the call utters the registered words, the call restriction is lifted and they can make a call. Therefore, it is only necessary to register short words such as one's own name, and the registered words can be easily remembered and prevented from being forgotten, and the registered words can be easily recalled even in an emergency.

In addition, it is impossible to cancel the call restriction even if other people say the same words but their voices are different, so the reliability of the call restriction can be improved.

[Effect of idea]

As explained above, in the present invention, the call restriction is lifted only when the person who registered the voice utters the registered words, and even if another person utters the same words, the call restriction is lifted because the voice is different. Can not do it. Therefore, the words to be registered should be short, easy to remember, and hard to forget. therefore,
The effect is that it is possible to carry out transmission regulation easily and with high reliability.
