Abstract

PURPOSE:To obtain the automatic telephone answering device which calls a called subscriber only when a calling subscriber voices a specific word and does not answers to a silent telephone call. CONSTITUTION:A speech detecting circuit 8 detects the specific speech (for example, ''Hello! Is this Mr. -?'') of the calling subscriber which arrives through speech lines 1, 5, and 7. When the specific speech is detected, a control signal is sent out to a speech answering circuit 10 and a calling circuit 12 through a control line 9. Consequently, the speech answering circuit 10 and calling circuit 12 are both activated and the speech answering device 10 sends out an answer message such as ''Yes, Mr. -? Hold on, please.'' to the calling subscriber through speech lines 11, 5, 1 and also transmits a tone ringer tone, etc., to let the subscriber know the incoming.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an automatic telephone answering device that can automatically prevent calls such as silent calls or power calls.

[Prior Art] In recent years, as the penetration rate of telephones has increased, the number of harassing calls such as silent calls that misuse telephones has increased, causing inconvenience to many people. Conventionally, in order to combat such nuisance calls such as silent calls, it has been necessary to use an answering machine or change the telephone number.

The items were expensive and the procedures were complicated. Additionally, there were other problems, such as even if the phone number was changed, the effect would only be temporary.

[Object of the Invention] The present invention solves the above problems, and provides an automatic telephone answering device that calls the called name only when the caller makes a predetermined voice and does not answer silent calls. The purpose is to

[Configuration 1 of the Invention In order to achieve the object of the present invention, the configuration of the present invention includes an automatic call reception circuit that detects an incoming call and connects a telephone line to the sound μ detection circuit, and a an acoustic detection circuit that detects a predetermined voice of an incoming caller and sends a control signal; and a voice detection circuit that is activated by the control signal and sends a response message to the caller over the telephone line. , a paging circuit which is activated by a control signal to page the called party.

[Description of Embodiment] Next, an embodiment of the automatic telephone answering device according to the present invention will be described with reference to accompanying drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

In the figure, reference numeral 1.3 denotes a communication line (wooden line), to which the telephone 4 is selectively connected via the switch 2. ! /Hf device 2
is also selectively connected to an automatic call receiving circuit 6 using a telephone line (drop-in line) 5. In this automatic answering device 4, the switching device 2 is switched to detect an incoming call coming in via the telephone line 1.5.When this incoming call is detected, the telephone line (drop-in line) 7 is switched to the voice detection circuit 8 Connect to. Voice detection circuit 8
detects a predetermined voice of the caller (for example, 1, ``Hello, hello...'') coming through the line 1, 5, 7. When this predetermined voice is detected, a control signal is sent to the voice response circuit 10 and the calling circuit 1 via the control line 9.
2, respectively. As a result, the voice response circuit IO and the paging circuit 12 are respectively activated. Conversely, in the case of a silent telephone, ie, when the predetermined sound is not detected, 1. The control signal is not sent, and the voice response circuit IO and ny output circuit 12 are inactive. activated jf N'
The answering device sends a response message to the caller via the telephone lines 11 and 5.1, saying, ``Yes, but please wait a moment.'' , the activated calling device 112 sends out a tone ringer or the like to the called name to notify 17 of the incoming call. As a result, the called person returns the switching device 2 to the main telephone 4 side and makes a call using the main telephone 4.

On the other hand, in the case of a silent call, no response message or message is sent. Therefore, in the case of a silent call, the called party is not disturbed.

In this way, after receiving the call, the caller receives the predetermined (7) 'Ff F'
The called party recognizes the incoming call and can make a call for the first time only when the caller utters the tone 741. Since the person cannot recognize the incoming call, he or she does not have to be confused by the nuisance call, and it is cheaper and simpler to counter nuisance calls than conventional methods.

E Effects of the Invention] 1. As explained, the automatic telephone answering device of the present invention has r
If the voice detection circuit does not detect the caller's predetermined voice after receiving a call, the voice response circuit and the paging circuit are inactive, which has the effect of not being distracted by harassing talk such as silent calls. .

It also has the advantage of being simple in configuration and easy to install.
