Abstract

PURPOSE:To attain the selection of extension/main trunk by means of transmission/reception of voice information by a caller even outside of a reception time by transmitting a message to the caller in automatic response at incoming call, recognizing the voice of the caller and performing connection control of line. CONSTITUTION:A line interface section 3 makes automatic response to an incoming call of a subscriber line 2. A voice information processing controller 8 drives a voice synthesizer 4, transmits a preset message to a caller via a line interface section 3 and the line 2, a voice recognizing section 6 is driven, the voice of caller is collated and recognized by a voice recognizing memory 7, the recognized dial number is transmitted to a connecting processing controller 11 as a selecting signal. The controller 11 drives a corresponding extension 10 based on the selecting signal and calls an extension 12. A channel switch 9 is driven by the response of the telephone set 12 to form a channel.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a telephone switching device in a private branch exchange telephone, an IOO number calling (DSA) switchboard, or the like.

As is well known, calling 100 means applying to number R100J without dialing the other party's phone number directly (no area code). After the call ends, if you hang up the phone and wait, the station will inform you of the call charges. This is the call method.

Conventionally, telephone exchange operations using this type of equipment have been operated by a human being at the reception. Therefore, especially in the case of a private branch exchange telephone, there is a drawback that calls cannot be received from the outside line to the extension line after the reception hours have passed, and countermeasures have been taken such as installing a separate direct line #1.

On the other hand, an attempt is being considered to allow direct dial-in from an outside line to all lines without a person handling the private branch exchange telephone. (2) The signal system must be reviewed and changed in order to transfer the extension selection signal, and other drawbacks exist. I haven't reached the point where I can.

The present invention has been made in order to improve the drawbacks of the prior art as described above, and therefore, an object of the present invention is to enable calls to be received from outside lines to internal lines regardless of reception hours;
Furthermore, our objective is to provide an automatic switching telephone system that does not require any review or modification of conventional signaling systems.

In order to achieve the above object, the automatic switching telephone device according to the present invention includes an automatic answering device that automatically answers when an incoming call is received, and a preset message that is sent to the caller in synthesized voice upon receiving the automatic answer. A voice response device that recognizes the caller's voice, an incoming voice recognition device that recognizes the caller's voice, and a connection control device that controls the connection of the line based on the output of the recognition device. The present invention is characterized in that the voice response device sends a message to the caller, recognizes the caller's voice, and controls the connection of the line.

The present invention will now be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, 1 is an automatic switching telephone device, 2 is a subscriber line,
3 is a line interface unit that has a function of automatically responding when a call is received; 4 is a voice synthesizer; 5 is a voice parameter memory that stores voice parameters for voice response; 6 is a voice recognizer; and 7 is a voice information storage unit for voice recognition. 8 is a voice information processing controller that controls the voice synthesizer 4 and the voice recognizer 6; 9 is a communication path switch that connects the office line and an extension line or each other; and 10 is an extension telephone. An extension circuit, 11 is a connection processing controller that controls the call path switch 9 and the extension circuit 10, and 12 is an extension telephone.

Next, the operation of the circuit shown in FIG. 1 will be explained.

In response to an incoming call from the office line (subscriber line 2), the line interface unit 3 automatically responds, and a signal indicating the automatic response is sent to the voice information processing controller 8. The controller 8 drives a speech synthesizer 4 that synthesizes speech based on the speech parameter memory 5, controls sending a preset message to the caller via the line interface section 3 and the subscriber line 2, and controls the voice synthesizer 4 to synthesize speech. The recognizer 6 is driven, the caller's voice (dial digits) is recognized while being checked against the voice recognition memory 7, and the recognized dial digits are controlled to be sent as a selection signal to the connection processing controller 11.

The connection processing controller 11t;t drives the corresponding extension circuit 10 and calls the extension telephone 12 based on the selection signal sent from the voice recognizer 6. and extension phone 1
2 responds, and drives the communication path switch 9 to form a communication path between the office line and the extension line.

Further, the connection processing controller 11 determines whether the extension to be called is busy or not based on the state of the extension circuit 10, and if it is busy, it sends a signal to the voice information processing controller 8, and the controller 8 again synthesizes the voice. 4 to send out a message indicating that the extension designated by the caller is busy and a message prompting the caller to call another extension number again.

From then on, follow the same procedure as when receiving a call to form a communication path between the multi-office line and the extension line.

Although the above description has been given using an example where the present invention is applied to a private branch exchange telephone, the present invention can also be applied directly to a reception desk for a current 100 number call (DSA). FIG. 2 shows an example in which the present invention is applied to a 100 number call (DSA).

Here, 1 to 9 and 11 are the same as in Figure 1, 13
14 is a subscriber circuit, 15 is a relay line, and 16 is a telephone set.

The circuit operation in FIG. 2 is similar to that in FIG. 1, with the following additions.

After the call ends, the connection processing controller 11 accesses the charge processing section 13 and obtains the call charge information, then drives the line interface section 3 to call the calling telephone and sends the call charge information to the voice information processing controller 8. send.

The audio information processing controller 8 drives the audio synthesizer 4,
Create a message with the call charge information inserted, and when the calling phone answers, enter the message.
Send the same message via Step 3.

As explained above, the present invention automatically answers an incoming call and automatically selects an extension or central office line based on the caller's voice. It is possible to receive calls from outside lines to internal lines without any need for additional measures such as running a direct line.

(2) Callers can select an extension or central office line by exchanging information by voice, similar to a telephone exchange that is manually operated by a normal operator, and there is no need for long-digit dialing. It has the advantage of not requiring any changes.
