Abstract

PURPOSE:To utilize DID service even for a rotary telephone set by providing a synthesis sound sending function for guide, a PB signal reception function and a speech recognizing device having a function such as the recognition of a simple numerical word such as zero or one. CONSTITUTION:When a central processing unit 2 detects an incoming call from a trunk line 4 set to the DID handling, a channel 1 connecting the trunk line 4 and the speech recognizing device 7, are connected. Then a synthesizing sound for a guide is sent from the speech recognizing device 7 and when the caller utters the number in voice or uses a pushbutton to apply dial input, the device 7 recognizes it, converts the recognized numeral into a dial code and informs it to a central processing unit 2. The central processing unit 2 selects an extension telephone set 3 corresponding to the code, an incoming instruction is given to the telephone set 3, a ring back tone is sent to the trunk line, a stop instruction is given to the device 7 and then the response of the extension telephone set 3, then the trunk line 4 and the extension telephone set 3 are connected mutually to form the talkable state.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention automatically answers an incoming call when a call is received on a designated central office line, and when the caller subsequently specifies an extension number, the call is automatically answered. DI, which is mainly used for in-house electronic exchanges, etc., automatically transmits incoming calls to extension telephones.
This relates to the D service device.

BACKGROUND OF THE INVENTION FIG. 4 shows a conventional electronic exchange. It shows the configuration of a DID service device. In Figure 3, 1 is 1
2 is a communication path, and 3 is a central control unit.

4 is a terminal control line dedicated to the I) ID service preset by the central control device 2; 6 is a 1-speech path control line; and 7 is a pushphone signal receiving device.

Next, the operation of conventional example C will be explained using the processing flow shown in FIG. When there is an incoming call on the central office line 4, the central control unit 2 detects it. If it is determined that the central office line 4 is a central office line for DID service, a dial tone is sent to the transmitting side of the central office line, and a pushphone signal receiving device 7 is connected to the receiving side to notify the user. Prompt dial input. In response, the user inputs the extension number of the person he or she wishes to call by pressing the pushbutton. The PB signal receiving device 7 converts this into a dial code and notifies the central control device 2, which analyzes the dial and selects the other party's extension telephone 3.
This office line is connected to the extension telephone 3. The above is the conventional D
This is the operation of the ID service device.

Problems to be Solved by the Invention However, in the above-mentioned conventional example, since dialing is performed via a central office line, there is a problem in that dialing cannot be performed unless the telephone used by the user is of the button telephone signal type. there were. Therefore, in the conventional service, this service requires one caller, the user, to
Since the main office line is treated as DID, we must make them aware that it cannot be used unless they use a telephone that uses push-phone signaling. Therefore, with this kind of service, there are few problems if the number of callers is limited, but if the service is not intended to be used by unspecified callers, it is almost impossible to use it. The problem was that it was possible.

An object of the present invention is to provide an excellent DID service device that does not cause any problems even when targeting unspecified callers.

Means for Solving the Problems In order to achieve the above object, the present invention provides a guiding synthetic sound sending function, a PB signal receiving function, and a "zero"//
A voice recognition device with a function that can recognize simple numerical words such as “chi” is installed, and when a call is received on a central office line, the central office line is connected to the voice recognition device and the extension number is announced by voice. The system is configured so that the extension telephone with that extension number can be automatically connected to the central office line.

Therefore, according to the present invention, it is only necessary to input the extension number by voice, and the DID service can be fully utilized even with a rotary telephone set other than a pushphone.

Example FIG. 1 shows the configuration of an embodiment of the present invention.

In Figure 1, 1 is a communication path, 2 is a central control unit, 3 is an extension telephone, 4 is a central office line set to be treated as DID, 6 is a terminal control line, 6 is a communication path control line, and 7 is a voice recognition device. be.

Here, since functions 1 to 6 are the same as the conventional one, only the function of function 7 will be explained.

The voice recognition device 7 can communicate with the central control device 2 via the terminal control line 6 as an I/F with the exchange, is activated by a command from the central control device 2, and transmits the results to the central control device 2. is configured so that it can be notified. Also, I/I with communication path 1? It is configured to be able to receive audio from the communication path 1 and to transmit audio to the communication path 1. Further, as shown in FIG. 2, the speech recognition device 7 includes a control section 8, a PB signal reception section 9, an audio signal reception/recognition section 1o, and a synthesized sound transmission section 11. The above three blocks are configured to operate respectively.

Next, the operation of the above embodiment will be explained based on the processing flow shown in FIG. The central processing unit 2 is a DID
When it detects an incoming call on the central office line 4, which is set to be handled, it instructs the voice recognition device 7 to ``send synthesized voice for sweets'', ``speech recognition interval 7'', and start receiving P B signal, and The communication path 1 connecting the line 4 and the voice recognition device 7 is connected.

As a result, the voice recognition device 7 transmits to the caller a synthesized voice for guidance, such as "This is ~. Please enter the extension number of the person you wish to call by voice or by using the pushbutton." be done.

In response, when the caller utters "go, cue, san, yong" or dials 6934 using the pushbutton, the voice recognition device 7 recognizes this,
The recognized digits are converted into a dial code and notified to the central control device 2. Central controller 2 that received this
selects the extension telephone 3 corresponding to the coat, sends an incoming call instruction to the extension telephone 3 and a ringback tone to the central office line, then issues a stop instruction to the voice recognition device 7, and then When a response from the telephone 3 is detected, the central office line 4 and the extension telephone 3 are connected to each other so that they can talk to each other.

In this way, according to the above embodiment, by first calling the exchange, and then inputting the extension telephone number by voice after the exchange answers, the extension telephone can be automatically called, and the DID service can be activated by pushbutton. It has the advantage that it can be easily used from a telephone other than a button.

Effects of the Invention As is clear from the above embodiments, the present invention allows dialing from a central office line to be performed not only by PB double signal but also by voice. Both have the advantage that DID services can be easily received. According to the present invention, D
This has the advantage that the burden of receiving ID services is reduced, and at the same time, the burden of managing the switching equipment can also be reduced, which is very advantageous in practice.
