1 is a block diagram showing the configuration of a first embodiment of the present invention.

The electronic exchange 1 of the present embodiment has an incoming trunk 3-1 to 3-n, a speech path switch 4, voice mail devices 5-1 to 5-n, and voice recognition devices 10-1 to 10-.
n, an incoming call register 6 for receiving a dial signal, a central processing unit 7 for controlling call processing, text data storage devices 11-1 to 11-n, a central processing unit 7 and voice mail devices 5-1 to 5-1. 5-n and text data storage device 11
-1 to 11-n.

The central processing unit 7 of the electronic exchange 1 is connected to the computer 2 via a bus 9.

Here, the line information received on the incoming trunk 3-1 is used to connect to the voice mail device 5-1.
The voice mail received on the incoming trunk 3-1 is stored in the voice mail device 5-1, and the stored voice mail is voice-recognized and analyzed by the voice recognition device 10-1, converted into text data, and stored in the storage device 11. An example of storing in -1 will be described.

First, when an incoming call is detected by the incoming call trunk 3-1, the central processing unit 7 connects to the incoming call register 6 for receiving dial information from the line. The incoming call register 6 receives the dial information coming from the line, and when the dial information is an access code to the voice mail device, the second line is used for notifying the line that reception preparation is completed, for example, a second line. The dial tone is transmitted, and thereafter, the dial information coming from the line is received and accumulated by a predetermined number of digits.

When the incoming register 6 completes the reception of the dial information of the required number of digits, the central processing unit 7 sends the received and accumulated dial information to the computer 2 via the bus 9 together with the line information. Computer 2
The voice mail device 5-1 is selected from the received dial information, and necessary information such as the mailbox number in the voice mail device is read from the database stored in the computer 2 in advance.

The computer 2 instructs the central processing unit 7 to connect the incoming trunk 3 to the selected voice mail device 5-1.
-1 is instructed to connect the incoming call and the control information including the mailbox number, the incoming line information, various service information and the like is sent to the selected voice mail device 5-1. Upon receiving this control information, the central control unit 7 connects the incoming call of the incoming trunk 3-1 to the specified voice mail device from the computer 2, and at the same time, the computer 2
Voicemail device 5 with specified control information received from
-1 to -1 via the bus 8.

As a result, the voice mail device 5-1 prepares for storage in the mailbox number designated by the computer 2, service preparation, etc. When the preparation is completed, the voice mail received on the incoming trunk 3-1 is sent. The call is sent to the voice mail device 5-1 and the voice mail device 5-
1 accumulates the incoming voice mail,
The accumulated voice mail is transmitted, and the voice recognition device 10
-1 is used for voice recognition and analysis, converted into text data and transmitted to the text data storage device 11-1, and the text data storage device 11-1 stores the received text data. The stored text data is sent to the display unit of the computer 2 and displayed by operating the computer 2.

Next, a second embodiment of the present invention will be described.

[0016] Conventionally, a telephone connected to a communication line is difficult to hear because the other party's voice is low, and if the user cannot understand what he / she is speaking, by adjusting the voice volume of his / her own telephone,
I was listening to the other party by making the other party's voice louder.

In the conventional telephone method described above, since there is a limit to the control of the voice volume of the own telephone, there is a case where the talk of the other party cannot be understood even if the volume is maximized.

In view of this, in the second embodiment, the language of the other party is voice-recognized and the language in which the other party is speaking is displayed as text data, instead of listening to and understanding the story of the other party by voice. By doing so, it is possible to provide a telephone in which the conversation of the other party can be visually understood by characters.

That is, in the second embodiment, a telephone connected to a communication line receives a voice signal transmitted via the communication line, recognizes the voice signal, analyzes the voice signal, and converts the voice signal into text data. By providing a text data conversion means for outputting, a storage means for storing the text data output from the text data conversion means, and a display means for reading out and displaying the stored text data It becomes possible to recognize the language being spoken and display it as text data, and if the other party's voice is difficult to hear and you do not understand what you are talking, you can hear and understand the talk of the other party by voice. Instead of, by recognizing the language of the other party, and displaying the language of the call as text data,
You can visually understand the other party's story.

FIG. 2 is a block diagram showing the configuration of this embodiment. The telephone of this embodiment has a handset (handset) 21 which is one of voice input means, a microphone 22 which is one of voice input means, and a speaker 23 which is one of voice output means. These handsets 2
