It is input to the unit 113 (step S102). The voice recognition unit 113 recognizes the input voice, converts it into text, and transmits the name text information to the telephone directory search unit 115 (step S103). The telephone directory search unit 115 searches the telephone directory data storage unit 114 based on the received text information of the name (step S104). Here, in this embodiment (FIG. 5), a process of excluding the title "san" from the search character string is performed, and a search character string other than "san" matches the pre-registered "name". Shown.

Next, the telephone directory search unit 115 searches for the name text information and the corresponding telephone directory (corresponding telephone directory data) in the telephone directory data storage unit 114, and the name from the telephone directory data storage unit 114. The corresponding telephone directory data corresponding to the text information is extracted as a search result (step S105). The telephone directory search unit 115 extracts one or more groups of pairs of the name and the corresponding telephone number, but outputs "none" as a search result when the name does not exist.

When the telephone directory search result data in step S105 is acquired, the telephone directory search unit 115 sends the corresponding telephone directory data of the search result to the telephone directory data transmission unit 116 (step S106), and the search result is sent to the telephone 10 via this (step S106). Is returned (step S107). As a result, the search result (result "No80, No81 ..." of one or more groups of the pair of the telephone number corresponding to the name) is displayed on the screen of the display unit 17 of the telephone 10 (or, if the name does not exist, " "None" is displayed), and the operator makes a selection input by key operation (numeric keypad, cursor key, clear key, enter key, etc.), and from the search result to the terminal related to the target callee via the main control unit 101. It is possible to make a call (order "No81") (step S108).

The voice recognition function can be used at a cost.

(Modification example)
In the first embodiment, the telephone directory search process (voice search mode) is activated in response to a key press by a key operation of the telephone directory 10 (step S101 in FIG. 5), but the voice recognition unit of the telephone directory search unit 111. Even if 113 is always activated and the voice search mode is activated in response to a specific voice signal generated by voice input from the telephone 10, for example, "voice recognition" or "phonebook search". good. As a result, the voice recognition unit 113 receives the telephone directory search command and activates the telephone directory search process (as step S101 in FIG. 5).

Further, in the first embodiment, the destination is specified by selecting the telephone directory from the telephone directory search result displayed on the display unit 17 by the key operation of the telephone 10 (step S108 in FIG. 5), but the key operation is not performed. It may be configured so that the destination can be specified by voice. Here, in step S108 of FIG. 5, since the processing is performed in a state where the voice path between the telephone 10 and the voice recognition unit 113 is connected, it is possible to specify the destination by voice instead of key operation. That is, when a plurality of telephone directory search results are shown, the operator selects the target destination by utterance, and the private branch exchange 100 side identifies the destination by voice recognition to perform the transmission process (FIG. 5). It is possible to move to step S108). Further, even when a part of the telephone directory search result data (one screen display) is sequentially transmitted from the private branch exchange 100 to the telephone 10 (instead of step S107 in FIG. 5) in response to the display request of the telephone 10, the key is also used. It is also possible to request the display of one screen display by voice instead of operation. According to this modification, the convenience of operation by the operator is improved.

Further, in the first embodiment and the modified example, the search result of the telephone directory is displayed on the screen of the display unit 17 of the telephone directory for notification. However, the method is not limited to this method, and other notification methods may be selected. good. For example, it is also possible to notify the operator of the search result of the telephone directory as voice by using a voice synthesis technology (TTS: Text-To-Speech) that converts text data into voice.

FIG. 6 is a functional block diagram showing a schematic configuration of a telephone directory search unit in the private branch exchange of the second embodiment.

As shown in FIG. 6, this embodiment is the same as the first embodiment except that the voice synthesis unit TTS is added to the first embodiment.

In this case, the phonebook search unit 115 searches and extracts the voice information "name" recognized by the voice recognition unit 113 and the corresponding "phone number" (corresponding phonebook data) from the phonebook data storage unit 114. Then, it is passed to the voice synthesis unit TTS as a search result.

The voice synthesis unit TTS transmits the corresponding voice phone book data synthesized from now on together with the corresponding phone book data to the telephone 10 via the telephone directory data transmission unit 116. The telephone directory data transmission unit 116 transmits the output to the telephone 10, and displays and utters the search result on the display unit 17 and the handset unit 15 (FIG. 2).
