Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device, and more particularly, to a communication device that enables a communication by performing a predetermined response operation when receiving a communication request signal from a calling side. Used as a telephone or intercom.

2. Description of the Related Art Conventionally, as long as a telephone or an intercom is in an operable state, a ringing sound means such as a bell is unconditionally activated when a call request is made by a dial operation or a button operation on the calling side. .

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The conventional communication device cannot selectively receive a call when an incoming call is received as long as it is placed in a normally operable state. For this reason, they are forced to respond by receiving calls from unfamiliar parties such as mischievous calls, wrong calls, telephone sales, and push-to-sell visits. In order to avoid this, if the ringing tone is set to be low or not ringing, or if the communication device itself is turned off, it may be difficult or impossible to respond to a call from a necessary party.

Means for Solving the Problem The communication device of the present invention comprises a control storage means (18), a keyboard (19), a voice recognition device (8), a voice output device (11), and a call communication means (10). And a control storage means (18) which, when a command signal is input from a keyboard (19), inputs a voice code via a voice recognition device (8) and stores it in the storage means (15). It is possible to register and set, input the call mode selection signal from the keyboard (19),
When the call mode selection signal is the encrypted call mode signal and the voice code is registered and set, it is determined that the call mode is the encrypted call mode, and when the call request command is input, the caller is compared with the voice code. The voice output device (11) outputs a voice signal requesting the user to input, and the collation voice code returned from the caller is collated with the voice code. When they match, the call connection means (10) is connected. If the call mode selection signal is the encrypted call mode signal and the voice code is not registered, or if the call mode selection signal is the direct communication mode signal, the direct communication mode signal is issued. When the call request signal is input, the call connecting means (10) is connected to emit a ringing tone.

Action With the above configuration, unless a verification voice code encoded in a preset voice code is input, the normal call operation after the ringing tone is not performed, so a call request from an unspecified person who does not know the voice code is made. , In particular, it frees you from the annoyance of unsolicited call requests such as prank calls, wrong calls, telephone sales, and push sales.

Further, even if the voice code is accidentally deleted due to an accident or the like and the voice code is not set, it is determined as the "direct communication mode" and the call is enabled, so that the essential function of the communication device can be maintained.

Embodiment Hereinafter, a communication device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a communication device in one embodiment of the present invention, and FIG. 2 is an external perspective view of a telephone as a communication device.

In the figure, a microcomputer 18 is a control storage means, and comprises a CPU 2, a RAM 15 and a ROM 16 which are storage means. For CPU2, numeric keypad 3, auxiliary key 4,
5, a keyboard 19 including the encrypted call mode setting key 6 and the direct call mode setting key 7 and the voice recognition device 8 are connected via the man-machine interface 9.

Further, the call control gate 14 of the call contact means 10 and the voice output device 11 are connected to each other via the system operation interface 12.

In the call contact means 10, the ringing tone generating means (not shown) is first activated in response to a call request command from the dialing operation on the calling side from the telephone line 13 connected to the call contact means 10, and then the handset 17 is lifted. What enables a call by the call response start operation of is used.

When the cipher input command is given to the CPU 2 by the ten-key 3 and the auxiliary keys 4 and 5, the call communication means 10 produces a desired voice cipher through the voice recognition device 8 and the man-machine interface 9 by its own call function. It is also wired so that you can enter it.

Also, the call line 13 connected to the call contact means 10
Is also branched and connected to the voice recognition device 8 and the CPU 2,
The call request signal is input to the CPU2, and the verification voice code can be input to the CPU2 from the caller side through the voice recognition device 8.

The voice output device 11 outputs a predetermined voice in response to a signal from the CPU 2 and is connected to the call line 13.
The call control gate 14 is a switch means provided in a connection portion for the call contact means 10, and the call contact means 10 and the call line 13
Connect and disconnect.

In response to the input of the call request signal, the CPU 2 transmits / receives necessary data to / from the RAM 15 and performs necessary input, output and calculation processes according to the program written in the ROM 16.

As shown in FIG. 2, the microcomputer 18 is mounted on the telephone body together with the call communication means 1. The phone body is next to the part where the handset 17 is installed,
A numeric keypad 3, auxiliary keys 4 and 5, and a keyboard 19 including keys 6 and 7 for inputting an encrypted call mode selection signal and a direct call mode selection signal are provided.

Hereinafter, a series of operations of the present invention will be described based on the cryptographic operation processing routine shown in FIG. 3 and the call control routine flowchart shown in FIG.

First, the input of the voice code for making it possible to receive only the call from a specific party is made in steps (1) to (6) of the flowchart of FIG. For the cipher input command in step (1), use the handset 17 to step
17a is turned on, the numeric keys of numeric keypad 3, auxiliary key 4,
This is done by inputting a signal to the CPU 2 by a predetermined combination operation with 5. When there is a cipher input command, the setting cipher input gate is opened and the handset 17 by the call contact means 10
Digitize the voice code from the voice recognition device 8.
Input to CPU2.

If the voice encryption is set first, the setting voice encryption input later is stored instead.

Next, when it is desired to erase the set voice code, in step (7), the set voice code erase command signal is input to the CPU 2 by a specific combination operation of the point key 3 and the auxiliary keys 4, 5 different from the above. It As a result, the set voice code is erased according to steps (8) and (9) in the flowchart of FIG.

The call control is performed by the steps (1
0) to (17). When a call request signal is input to the CPU 2 based on the dial operation from the caller, it is first determined in step (10) whether the call mode is the encrypted call mode.
This is determined to be the encrypted call mode when the encrypted call mode selection key 6 is pressed, the call mode selection signal is the encrypted call mode signal, and the voice code is registered and set. It is determined to be the direct communication mode.

Otherwise, if (a) the direct call mode selection key 7 is pressed and the call mode selection signal is a direct call mode signal, (b) the encrypted call mode key 6 is pressed and the call mode selection signal is changed. This is a case where the voice code is not registered and set even though it is the encrypted call mode signal.

Therefore, even if the voice call mode selection signal is the voice call mode signal when the voice call mode key 6 is pressed and the voice voice code is registered and set, the voice voice code is mistakenly deleted due to an accident or the like and the voice voice code is not set. If so, it will be determined to be the direct communication mode.

When it is determined that the mode is the encrypted call mode, guidance to that effect and signal output of the encrypted voice request are given to the voice output device 11 shown in FIG. 1 in step (11). The voice output device 11 is composed of a voice synthesizer or an appropriate voice recorder, and operates by the input of the signal to give the voice signal of the guidance and the request to the caller through the communication line 13. When the verification voice code is input from the caller in response to this, it is read in step (13), and then the input verification voice code is matched with the set voice code in step (14). Is determined.

If the collated voice code matches the set voice code, an operation signal is given to the call control means 14 in step (15). As a result, the call control means 14 connects the call line 13 to the call communication means 10 and activates a calling sound member (not shown) provided therein.

At this time, it is notified that there is a call request for the first time, and a call response operation such as lifting the handset 17 causes a call line
Calls with the caller through 13 will be possible as usual.

In step (14), if the input verification voice code does not match the set voice code, or if the verification voice code is not input, the ringing tone for the incoming call in step (15) is not emitted. In addition to this processing, the processing of voice code re-input guidance in step (17) is repeated until the counter in step (16) reaches the counter number n = 3 (step (1
2)), if the specified verification voice code is still not entered, EN after the counter is reset in steps (18) and (19).
It becomes D.

As a result, it is possible to avoid calls from unspecified people who do not know voice code, as well as to avoid making ringing tones associated with call requests, and to avoid making calls with people who are unwilling, such as mischief, wrong phone calls, or telephone sales. Of course, the annoyance caused by the generation of unnecessary ringing sounds is eliminated.

When it is determined in step (11) that the call mode is not the encrypted call mode, steps (10) to (14) are skipped, and an operation signal is given to the call control means 14 only by the call request signal from the caller. As with a normal telephone, a ringing tone is emitted in response to a call request from any other party, and by responding to it, all calls can be made.

On the other hand, for a call from itself, a signal obtained from the normal transmission procedure, that is, a signal that the handset 17 is raised and the switch 17a is turned on, gives an operation signal to the call control means 14 from the CPU 2 and makes a call with the call contact means 10. This is achieved by putting the line 13 into a connected state.

In the above embodiment, the call is controlled only depending on whether or not the caller can input the matching voice code corresponding to the set voice code, but the call can be made only at the set time or time zone. The mode setting to be performed can be used together.

In addition to a telephone, it can be applied to an intercom and other similar devices.

EFFECTS OF THE INVENTION According to the present invention, unless a verification voice code encoded in a preset voice code is input, a normal call operation below the generation of a ringing tone is not performed. You can free yourself from the hassles of call requests from people, especially mischievous calls, wrong phone calls, telephone sales, and push-to-sell call requests.

Further, even if the voice code is accidentally deleted due to an accident or the like and the voice code is not set, it is determined as the "direct communication mode" and the call is enabled, so that the essential function of the communication device can be maintained.
