In the telephone switching system that is an embodiment of the present invention configured as described above, the voice of a caller sent from a certain telephone 1 is extracted by the voice recognition device 3 and converted into a voice pattern. , converted to the destination code. Next, a phone number corresponding to the call destination court is obtained from the call destination file 4, and a telephone exchange is performed based on this phone number.

Furthermore, a specific example of the operation of the telephone switching system which is an embodiment of the present invention will be explained with reference to FIGS. 1 and 2. For example, when caller "A" wants to call "Sales Department Sales Section 1," he picks up the handset of telephone 1 and simply uses the unified abbreviation "Sales Department" without operating the dial or button. "Lesson 1," he says. Then, the voice patterning device 31 in the voice recognition device 3 generates a voice pattern corresponding to "Sales Section 1." Based on this voice pattern, using the comparison table 32 of all call destination voice patterns and call destination codes and the voice pattern comparison device 33, "Sales 1
Obtain the destination code corresponding to the department. Next, based on this call destination code, the telephone number corresponding to the call destination code of "Sales Department 1" is obtained using the comparison table 42 of all call destination codes and telephone numbers in the call destination file 4 and the telephone number search device 41. Search for.

Therefore, based on the telephone number searched in this way, the exchange 2 selects and connects the line, and a connection is established with the telephone 1 corresponding to "Sales Section 1".

By the way, speech recognition is usually very difficult when both the caller and the words are unspecified. However, when the number of call destinations, which are words to be voice recognized, is limited to about 100 to 200, such as in a private telephone system, the voice recognition device 3 can recognize the voice even if the caller is unspecified. Identification by recognition is possible. Here, even if the telephone number of the destination telephone 1 is changed due to organizational change, relocation, etc., all that is required is to change the comparison table 42 of all destination codes and telephone numbers in the destination file 4. Therefore, the user will not experience any inconvenience.

The recognition result by the voice recognition device 3 is conveyed to the caller by voice and asked for confirmation. At this time, in case of an error, the caller says "Next" and the second. Select the third call destination candidate. Then, if it is correct, say "Yes" and the line will be connected. On the other hand, if the recognition result of the voice recognition device 3 indicates that the predetermined call destination does not exist, the caller is informed by voice that "there is no matching person."

In addition, it can be used in cases where voice telephone exchange is not possible, especially when using in a place with a lot of surrounding noise.
Distinguish between telephone number information and voice information by rotating the dial or pressing a button on the telephone 1, and performing exchange using only the telephone exchange function in the conventional telephone exchange system described above, and the telephone exchange system of the present invention. The information identification device 5 shown in FIG. 1 may be provided in order to distinguish between the exchange performed by the voice telephone exchange function and the exchange performed by the voice telephone exchange function.

Note that although the above embodiment shows the case where the exchanger [2] has the overall control function, a separate small-sized computer may be used for control.

Furthermore, in the above embodiment, exchange fi2. Although the voice recognition device 32, call destination file, and information identification device 5 are described as independent devices, they may be combined as desired.

[Effects of the Invention] As explained above, the present invention provides a telephone exchange system in which a voice recognition device comprising a voice patterning device, a comparison table of voice patterns of all call destinations and call destination codes, and a voice pattern comparison device is installed in the exchange; It is equipped with a telephone number search device, a call destination file consisting of a list of all call destinations, and a comparison table of telephone numbers, and is configured to exchange calls between each telephone set by voice using the exchange control of the above-mentioned switching equipment.
