Abstract

PURPOSE:To attain automatic dialing of a telephone number retrieved by registering destinations and telephone numbers in advance in a tree form and selecting each node of the tree form by voice output so as to dial the object destination. CONSTITUTION:The telephone numbers and their destination names classified in the tree structure are registered in voice and when the normal telephone mode is switched into the retrieval mode by a key operation section 2, the uppermost node is outputted sequentially from a voice reply section 3. When an object node is outputted and any key is depressed, the node moves to the low order hierarchy and it is repeated till the object destination thereby applying automatic dialing to the destination. Thus, sure dialing is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a search telephone system, and more particularly to a telephone system that has a search function and automatically dials searched telephone numbers.

PRIOR ART A so-called voice dialing device is well known that automatically dials the number when you say the part you want to make a call, but it is expensive to use a voice recognition device to recognize the voice, and Since it is speaker recognition, it has disadvantages such as requiring user registration.

Purpose The present invention was made in view of the above-mentioned circumstances.
In particular, the purpose of this invention is to provide a search telephone system that allows reliable dialing without having to memorize or look up the telephone number of the other party when making a call.

Ao - 11 precepts.

In order to achieve the above object, the present invention (1) registers telephone numbers and their destination names categorized in a tree structure by voice, and when making a call, responds by voice from the top of the tree structure; , When the target node is output, press any key to move to a lower level, and repeat this process to the target destination to automatically dial the destination.
Alternatively, (2) a telephone number used in common with a plurality of voice response devices is registered in the exchange, and the name of the other party is registered, and the telephone exchange number feature is a search telephone exchange having the function of (1). Hereinafter, the present invention will be explained based on examples.

FIG. 1 is a block diagram for explaining one embodiment of the present invention, in which 1 is a handset, 2 is a key operation section, 3 is a voice response section, 4 is a control section, 5 is a dialing section, Reference numeral 6 indicates a display section, and 7 indicates a telephone line. First, a key operation section is used to switch from normal telephone mode to search mode. Then, the voice response unit 3 sequentially outputs the highest nodes. In the example shown in FIG. 2, "Extension", 'Affiliate Company', 'Business Partner', etc. are output. Here, select the target party as Business Partner - Osaka - 〇×
If it is a trading company, select the selection key (
For example, press 1#"), then 'Tokyo'.

"1 Osaka" and 1 Nagoya" are output, but when "Osaka" is output, press the selection key. Next, when "QX Shoji" is output, press the selection key. Then, the phone number will be displayed on the display. Then, the control department calls Ox Shoji. Of course, you can also make regular calls by using the regular numeric keypad.

To register a phone number □, please use registration mode, for example "uTa"
), if the tree structure is as shown in the registration example in Figure 2, press '1' and say 'extension'. Press ``u2'' and say ``affiliated company.''

At the next level, press "11" and say "President's Office", and since there is no tree below that, press "#" and enter the phone number. Press “#” again to mark the end,
To register Ox Shoji, press "322'", say 4=Qx Shoji, and press "#06...#". To finish registration, press "Umbrella". These operating steps This can also be done with audio output guidance.

FIG. 3 is a block diagram for explaining another embodiment of the present invention, and this embodiment has a voice recognition section 8 added to the embodiment shown in FIG. This speech recognition unit is for recognizing song words such as "yes", "no", etc. by unspecified speakers.

There is no need for the user to create a dictionary; therefore, in this embodiment as well, if the user presses the selection key in the same manner as described in the embodiment shown in FIG. The voice recognition unit 8 recognizes the message and moves to the next node, or if there is no lower tree, the call is made from the dialing unit. With voice recognition, there is a possibility of misrecognition, so if you make a misrecognition or make a mistake and proceed to the next step, you can return to the previous step by saying "No, no."

Furthermore, when providing guidance by voice response, selection can also be made by uttering 'yes' or 'no'.

FIG. 4 is a block diagram for explaining another embodiment of the present invention, in which 10 (10,, 10□).

103...) is an extension telephone, 11 is a telephone exchange, 12
(12, 12, 123...) are outside lines, 13 is a control unit, 14 is search telephone number data, 15a, 15b are voice response units, and 16 is voice data.
For example, by pressing "#" on the telephone 10 connected to the telephone 10, the mode is switched to the search mode, and the desired destination is determined using the search function shown in the embodiment shown in FIG. Then, the control unit 13 outputs the corresponding telephone number to the exchange, and the exchange makes a call to the other party. Note that since there is a high possibility that the voice response device will be used simultaneously by multiple telephone extensions connected to the exchange, a plurality of voice response devices are prepared. Since the telephone number and voice data can be accessed from anywhere, only one set is required.

According to this embodiment, although the data to be registered is limited to data that is commonly used, it is cheaper than applying the embodiment shown in Fig. 1 to all extension telephones, and registration is also done at the center. This has the advantage that it can be done once and one person does not have to go through the trouble of registering.

FIG. 5 is a block diagram for explaining another embodiment of the present invention. In this embodiment, a plurality of speech recognition devices 17a and 17b are added to the embodiment shown in FIG. Similar to the embodiment shown in FIG. 3, the selection is made by voice.

As is clear from the above explanation, according to the present invention, by registering the destination and telephone number in advance in a tree configuration, each node in the tree configuration can be selected by voice output. It is possible to make a call to the intended recipient, and there is no need for an expensive voice recognition system.Furthermore, although the number of recipients is limited, by registering at the center, individuals can save themselves the trouble of registering.
