Abstract

PURPOSE:To attain the efficient service by providing a voice recognition device and a message input output device to the exchange so as to send a message registered in advance by each of plural called parties when the caller is absent. CONSTITUTION:The caller side is provided with a voice recognition device 8 to recognize a voice from a caller and a message input output device 9 registering a message of the called party in advance and able to output the message to the caller and able to input the message from the caller. When the caller records the message to the message input output device 9, the voice recognition device 8 recognizes the voice of a name recorded in advance in the message input output device 9 by the called party and the voice of the name of the caller itself recorded in the message input output device 9 by the caller to detect the difference and sends the reply message from the desired called party stored in advance. Thus, the state of the called party is easily grasped by the caller and the necessity of redialing is avoided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital exchange having a message input / output function.

[0002]

2. Description of the Related Art FIG. 3 shows a block diagram of a conventional digital exchange, which will be described below. 1 is an office line trunk that first receives an incoming call from a caller, 2 is a T switch that selects a call destination telephone to perform line connection, and 3 is connected to a telephone 4 respectively, and receives a line connection command and receives T
A subscriber circuit 5 that connects the switch 2 and the telephone 4 captures the office line trunk 1 when any of the telephones 4 receives an incoming call and goes off hook, and closes the T switch 2 and the subscriber circuit 3. It is a central processing unit (hereinafter, referred to as "CPU") that enables a telephone call.

In the digital exchange record constructed as described above, when an incoming call enters the trunk line trunk 1, the CPU 5 causes the subscriber circuit 3 connected to the destination telephone 4 to receive the telephone 4
Issue a command to call. When the called party goes off-hook in response to the ringing of the telephone set 4, the CPU 5 issues a capture command to the T-switch 2, and connects the office line trunk 1, the T-switch 2, the subscriber circuit 3 and the telephone set 4 to perform a call process. ..

[0004]

However, in the above-mentioned conventional method, when the called party is absent, the calling party cannot accurately grasp the situation on the called party side and must call again. There was a problem such as not becoming.

[0005]

In order to solve the above-mentioned conventional problems, the present invention provides a voice recognition device for recognizing a voice from a calling party on the called party side, and a message on the called party side in advance. In addition, a message input / output device capable of registering a message, outputting a message to the caller side, and inputting a message from the caller is provided.

[0006]

With the above configuration, the message can be accurately transmitted to the calling party even when the called party is absent, and the message from the calling party is similarly sent to the called party. And receive efficient services.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a digital exchange according to the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of an embodiment of the present invention. 6 is a trunk line trunk, 7 is a T-switch, 8 is a voice recording of the name of the called party in advance, and a change between the name entered by the calling party by voice and the registered name of the called party is detected. A voice recognition unit, 9 is a message input / output device for recording a caller's message and inputting / outputting a callee's response message, 10 is a subscriber circuit, 11 is a telephone, and 12 is the above 6 to 11. It is a CPU that controls the operation.

The operation of the digital exchange thus constructed will be described. First, the voice recognition device 8
Then, the name of the called party corresponding to the telephone 11 is recorded by voice. In the message input / output device 9, a response message corresponding to each called party is recorded by voice. Here, FIG. 2 is a conceptual diagram of a memory configured in the message input / output device 9, and when a called party is determined to be absent after a lapse of a certain calling period, the caller can obtain a desired message. It is composed of a common message storage area that stores a message requesting that the called party name be recorded by voice, and a response message storage area that is assigned to each called party.

When an incoming call is received from the calling party, the telephone 11 is ringed via the office line trunk 6, the T switch 7 and the subscriber circuit 10. When one of the telephones 11 is hooked off, the CPU 12 captures the office line trunk 6 and forms a communication path.

However, when the called party is absent and the called party does not respond after a certain period of time, the CPU 12 sets the office line trunk 6 and the message input / output device 9 to the T switch 7
Connect by. The CPU 12 sends an activation signal to the message input / output device 9 to send the message stored in the common message storage area indicated by address 1 (# 1) in FIG. 2 to the caller. A message requesting that the called party is currently absent, that a desired called party name be input by voice, and that the caller's message be input by voice in the common message storage area. Etc. are stored. Next, the CPU 12 connects the station line trunk 6 and the message input / output device 9 with the T switch 7, and waits for an input from the voice from the caller. When the caller finishes inputting the name of the desired called party and other messages, the CPU 12 activates the voice recognition device 8 and the desired data is received from the voice data of the calling party stored in the message input / output device 9. The caller is determined and the response message stored by the desired called party is sent from the message input / output device 9.

[0011]

As described above, according to the present invention, since the exchange has the voice recognition device and the message input / output device, the necessary message can be accurately transmitted to the calling party even when the called party is absent. In addition, the caller does not need to call again, and the message from the caller can be transmitted to the called party, which improves the service.
