DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a private branch exchange system according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of a main part of an embodiment of a private branch exchange system according to the present invention. In FIG. 1, reference numeral 100 denotes a private branch exchange constituting the private branch exchange system. Reference numeral 200 denotes an extension telephone constituting the private branch exchange system, which comprises a plurality of units (not shown). An input / output unit 1 connects the system to an external line. A call signal detection unit 2 detects a call signal from an outside line and closes a loop with the outside line via the input / output unit 1 at a required number of times. Reference numeral 3 denotes a first memory for storing data and the like for speech synthesis. Reference numeral 4 denotes a voice synthesizing unit that synthesizes a message voice based on the message data read from the first memory 3 and the second memory 5. Reference numeral 5 denotes a second memory for storing a plurality of extension numbers, names (personal names) of persons using the telephone corresponding to the extension numbers, data for speech synthesis, and code numbers as a pair. FIG. 2 shows an example of data registered in the second memory 5. Reference numeral 6 denotes a discriminating unit that calls a plurality of name data stored in the second memory 5, compares the name data with the voice data of the caller, and calls the extension number and the data for voice synthesis for the corresponding name when they match. Reference numeral 7 denotes an exchange connection unit for exchange connection with the extension telephone of the extension number called by the discrimination unit 6. Reference numeral 8 denotes a data transmission unit which sends the data for speech synthesis called by the discrimination unit 6 to the extension telephone. A control unit 9 controls each unit. The extension telephone 200 has a notification unit 10 for generating a ringing tone and an input / output unit 11 for making a call connection with an outside line via a private branch exchange, as in the prior art, and transmits data for voice synthesis sent from the private branch exchange 100. A receiving unit 12 for receiving the data;
, A notification unit 10, an input / output unit 1
1, a control unit 14 for controlling each of the receiving unit 12 and the voice synthesizing unit 13.

Next, the operation of the private branch exchange system according to the present invention will be described with reference to the flowchart of FIG. A call signal is input from an external line via the input / output unit 1. This signal is detected by the call signal detection unit 2, and it is determined that there is no mistake in the required number of times, for example, the third time (Step 1: Yes, hereinafter abbreviated as ST1: Yes, etc.). Is closed (ST2). Next, the message voice data is read out from the first memory 3 via the control unit 9, and voices such as "please inform the name of the called party" synthesized via the voice synthesis unit 4 are transmitted to an outside line (ST3).
If the caller on the outside line has previously specified the caller who wants to talk, the name of the callee is uttered in response to this guidance. The voice data of the caller is input to the discriminating unit 6 and is compared with the name data read from the second memory 5 via the control unit 9. If it is judged that they match (ST4: Yes), the corresponding name is entered. The corresponding extension number is called, the connection is switched to the corresponding extension telephone at the switching connection unit 7 via the control unit 9 and a call is made (ST6), and then the voice corresponding to the name stored in the second memory 5 The data for combination is transmitted from the transmission unit 8 to the reception unit 12 of the extension telephone 200 connected via the control unit 9 (ST7). Extension telephone 200
The voice synthesizing data received by the receiving unit 12 is transmitted via the control unit 14 and the voice data synthesized by the voice synthesizing unit 13 to the notification unit 10 via the control unit 14 (ST8). The notifying unit 10 can make a call by directly off-hook the extension phone 200 and making a telephone call by notifying the ringing sound but notifying that "the call is Mr. OO" (ST)
9). After the end of the call, the loop of the communication line is released via the input / output units 1 and 11 when the called party or the calling party goes on-hook (ST10), and a series of operations is ended.

In the above ST4, when the caller does not utter the name or when the utterer does not correspond (ST4: N
o) The voice of the first memory 3 synthesized by the voice synthesizing unit 4 such as "Please wait as we are now connected to the operator" is transmitted to the outside line (ST5). The operator receives the request from the caller directly and connects to the corresponding extension telephone.

In the present invention, a system for connecting and notifying an extension based on voice data from a caller has been described. However, a DTMF signal is requested from the caller and the DTMF signal is transmitted.
It is also possible to connect the corresponding extension based on the signal and notify the called party. In addition, it is not possible to cope with the same sex only by the name registered in the memory, so that it is preferable to store the department together. In the present invention, the first and second memories are used to make the description easy to understand, but there is no problem even if one memory is actually used.

[0010]

As described above, according to the private branch exchange system of the present invention, the caller speaks the name of the callee to be connected to the telephone, thereby connecting to the corresponding extension telephone, and the extension telephone side. The notification unit can confirm who the call request is before going off-hook, and eliminate the need for a call transfer.
