JPS59205894A - Key telephone set - Google Patents

Abstract

PURPOSE:To form a small sized and smart key telephone set which is connected selectively to an optional line without using a line selecting button by closing a channel switch designated by the output of a speech recognition circuit. CONSTITUTION:When a number corresponding to a trunk line going to be desired by a caller is inputted from a microphone 101 or a transmitter 109, its voice signal is inputted to the speech recognition circuit 103 via a voice amplifier circuit 102. Plural voice patterns are registered in the speech recognition circuit 103, the pattern of input voice is compared with the registered voice pattern so as to identify a desired circuit. The result of identification is applied to a channel switch control circuit 104 so as to close the designated channel switch 105 and connect a designated trunk line 112 to a channel network 106. Then, the key telephone set is connected to the desired trunk line 112 thereby attaining talking or originating.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a button telephone that accommodates a plurality of office lines (! or PBX lines) and allows any office line etc. to be selected and used.

Conventionally, this type of button telephone has multiple central office lines (or PB
It is equipped with line selection buttons corresponding to each of the central office lines or PBX lines (hereinafter simply referred to as lines) that you want to use, and allows you to select any line. has been done. The above-mentioned line selection button requires mechanical switch contacts and a button mechanism, so conventional button telephones have to be large. The object of the present invention is to solve the above-mentioned conventional drawbacks and provide a small and smart button telephone that can be selectively connected to any line without using a line selection button. It's about doing.

The button telephone of the present invention includes a plurality of call path switches each connected to a plurality of office lines or PBX lines, and by closing any of the above-mentioned call path switches, any office line or PBX line can be closed. A key phone that can be connected to a PBX line includes a voice recognition circuit that compares the output voice of a microphone or a transmitter with a plurality of preset voice patterns, and a call specified by the output of the voice recognition circuit. The present invention is characterized by comprising a communication path switch control circuit that closes the communication path switch.

Next, the present invention will be explained in detail with reference to the drawings.

The figure is a block diagram showing one embodiment of the present invention. That is, the dial circuit 107. Receiver 108° Transmitter 10
9 etc. are connected by a communication network 106 and can be connected to any office line 112 via a communication path switch 105. In addition, when not connected to a central office line, power for telephone calls is supplied from a parent device (not shown), and it is possible to make telephone calls with other similar key telephones. The above is almost the same as a conventional button telephone, but the call path switch 105 is not closed by pressing the selection button as in the conventional case.
The difference is that it is closed or opened under the control of a communication path switch control circuit 104, which will be described later. Of course, there are a plurality of office lines 112, and communication path switches 105 are provided corresponding to each office line. The same applies even if the two-station line 112 is a PBX line. The call path switch control circuit 104 closes the call path switch 105 corresponding to the line designated by the voice recognition circuit 103, and also identifies the incoming line based on the incoming call signal input via the call path switch 105. The light emitting diode driver circuit 110 is driven to cause the corresponding light emitting diode 111 to blink and emit light.

The light emitting diode corresponding to the line in use is controlled to be lit continuously.

The voice recognition circuit 103 inputs the voice input from the microphone 101 and the voice signal output from the transmitter 109 via the voice amplification circuit 102, and converts the input voice signal into a plurality of pre-registered voice patterns. compare. The number of types of the plurality of voice patterns is determined by the number 1 corresponding to the number of central office lines 112, for example, "1, 2, 2,
..., Jiyu'' class 10i. When the number corresponding to the office line that the caller wishes to use is input from the microphone 101 or the transmitter 109, the voice recognition circuit 103
By comparing the input voice pattern with the above-mentioned 10 registered patterns, it is possible to easily identify the desired line. The voice recognition circuit 103 supplies the identification result to the communication path switch control circuit 104, and the communication path switch control circuit 104 closes the specified communication path switch and connects the specified central office line 112 to the communication network 106. .

This connects the main button telephone to the desired central office line,
You can make calls or make outgoing calls. In the case of a call, it goes without saying that the dial circuit 107 is operated to send a dial signal to the central office line.

In this embodiment, there is no need to press a line selection button as in the conventional case. That is, in the case of an incoming call, the number of the incoming central office line is known by the flashing light emitted from the light emitting diode 111, and when the number is uttered, the voice recognition circuit identifies this, closes the corresponding call path switch, and connects to the call network 106. Connecting. Therefore, the caller can answer and talk by simply lifting the handset. For transmission, light emitting diode 1
You can connect to the desired line by selecting one of the 11 unlit lines and saying the number of the line. The voice recognition circuit 103 can identify at most 10 types of simple voices, so it can be identified with a relatively simple circuit, and the communication path switch control circuit etc. can also be formed compactly using digital integrated circuits. It is possible.

Therefore, the book and telephone are designed to be compact and smart as a whole, and there is no possibility that the selection button will be mistakenly connected to an undesired central office line as in the past.

As described above, since the present invention is configured so that any number of stations or PBX lines can be selectively connected using audio signals, there is no need for a mechanical line selection button. Formed 2. In addition, the operation is simple and there is no need to press the wrong line selection button as in the conventional case.
