Abstract

PURPOSE:To control the permission of incoming for a call from a specific person registered in advance and to control appropriately the incoming of the call from a person other than the above person, by providing the extraction means, storage means, comparison means, and control means of the feature data of a voice. CONSTITUTION:In a voice pattern storage part 13 in an incoming controller 3, the voice pattern of a caller which becomes the object of the permission of the incoming is registered in advance. Next, when the call is issued from an outgoing person, and a call signal is inputted via a central office line 8, connection guide announce is sent via a voice synthesis device 14, etc. And when the outgoing person issues response corresponding to the above announce, the voice pattern is extracted from the voice via a communication control part 9, a pre-processing part 10, a voice pattern extraction part 11. Next, a comparison and collation part 12 retrieves the storage part 13 based on voice pattern data supplied from the extraction part 11 in a real time. And it is detected whether the same voice pattern exists, and it is possible to control the permission of the incoming for the call from the specific person registered in advance and the call from the person other than the above person appropriately based a detected result.

Description

[Detailed Description of the Invention] J Purpose of the Invention] (Industrial Application Field) , a) Receive an incoming call from a caller to a telephone terminal. This invention relates to a telephone terminal incoming call control device that controls whether or not a call is received.

(Prior art) Today, as telephone communication has become deeply integrated into people's lives,
As a result, damage caused by crimes and mischief using telephones is also on the rise. Therefore, in order to prevent mischief and harassment by telephone, incoming calls are restricted using so-called passwords. That is, when a caller inputs a password by voice or PB signal in accordance with a message sent from a receiving terminal, incoming calls to the telephone terminal are permitted only if the password is correct. According to this method, it is possible to reject incoming calls from an unspecified number of callers who do not know the password. Therefore, prank calls can be repelled, but at the same time, there is a problem in that many calls are rejected simply because the password is not known.

(Problems to be Solved by the Invention) As mentioned above, in the conventional telephone terminal incoming call control device, the acceptance or rejection of incoming calls was controlled by passwords, so many people refused incoming calls simply because they did not know the password. There was a problem that a call was generated.

The present invention was made in order to solve the problems of the conventional telephone end missed call control m+ device, and its purpose is to:
It is an object of the present invention to provide a telephone terminal incoming call control device that can control whether or not to accept calls from specific persons registered in advance, and can appropriately control the incoming calls from other persons.

[Structure of the Invention] (Means for Solving Problems) In the present invention, a telephone terminal incoming call control device that is connected to a telephone terminal and controls whether or not incoming calls to the telephone terminal receives characteristic data of the other party's voice during a call. an extraction means for extracting the feature data, a storage means for storing the feature data, a comparison means for comparing the feature data stored in the storage means with the feature data obtained from the extraction means in real time, and an instruction from the outside. As a result, the telephone terminal enters a selection operation mode, and when the selection operation mode is selected, the telephone terminal is provided with a control means for causing the comparison means to perform a comparison after answering an incoming call, and controlling whether or not to accept an incoming call to the telephone terminal based on the comparison result. It consists of a telephone terminal incoming call control device.

(Operation) According to the above configuration, since the voice characteristic data of the specific caller is stored in the storage means, when a call is made, the comparison means can compare whether the call is from the above-mentioned specific caller or not. It is possible to detect whether the incoming call is connected to the telephone terminal or not.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 2 is a block diagram of one embodiment of the present invention. In this figure, reference numeral 1 indicates a telephone terminal incoming call control device, and this telephone terminal incoming control device 1 is connected between a central office line 8 and a telephone terminal 7 . Telephone terminal incoming call control device! 1 is a central office line interface 2 connected to a central office line 8, an incoming call control unit @3 that controls permission/denial of incoming calls to the telephone terminal 7 by voice recognition, a terminal interface 4 connected to the telephone terminal 7, and an operation unit 5 used for data input. , and a CPU 6 for overall control of the device body. The telephone terminal incoming call control device 1 functions equivalently to a telephone terminal from the central office line 8 side, and functions equivalently to a central office line from the telephone 7 side.

The incoming call control device 3 in FIG. 1 includes an incoming call control section 9, a preprocessing section 1
0, speech pattern extraction section 11 as extraction means 110, comparison and matching section 12 as comparison means 120, speech pattern storage section 13 as storage means 130, speech synthesis device 14, CP
Includes U16. CPU 16 is incoming call control unit 9
Together with this, the control means 160 is configured.

In order to operate this device, it is first necessary to register in advance the voice characteristic data (voice pattern data) of the other party to whom restriction is to be applied in the voice pattern storage section 13. There are various methods for this registration, but here we will adopt a method in which registration is performed during a call. The operation section 5 is provided with a key for instructing a registration mode for registration and a key for performing a selection mode for a selection operation (incoming call restriction operation).

Suppose that when you answer from the telephone terminal 7, it is the person who you want to reject incoming calls from now on. Then, a key for instructing the registration mode of the operation section 5 is operated. Having received this data, the CPU 6 controls the CP of the incoming call control device 3.
Instructs U16 to enter the registration mode. Then CPU 16
controls the incoming call control section 9 so that the other party's voice reaches the terminal interface 4 and the preprocessing section 10. This speech is decomposed into word units of one sound each in the preprocessing section 10 .

This decomposed sound data is sent to the speech pattern extraction unit 11, where it is compared with the sound data of the standard sound source, and the word that the sound means is specified (for example, "a", etc.). As in "I").

As a result, a certain word is associated with the corresponding voice unique to the other party. Furthermore, the voice pattern extraction unit 11 extracts voice characteristics (
For example, when the sound "a" is uttered, its frequency distribution, its temporal changes, etc. are extracted. As a result, a certain single sound is associated with characteristic data (voice pattern data) unique to the voice uttered by the corresponding caller. The sound meaning data and the voice pattern data are stored in the voice pattern storage section 13 in association with each other. As described above, the voice pattern recording/storage unit 13 stores voice pattern data for each sound such as the "Aiueo J50 sound" of the other party.

This operation is performed every time there is an incoming call from a person who wants to reject incoming calls from the next time onwards. Next, the operation in the selection mode in which the incoming call restriction operation is performed will be explained with reference to the flowchart shown in FIG. A selection mode key operation is performed in the operation unit 5 to enter the selection mode.

First, when a call is made by a caller, a calling signal arrives via the office line 8, and the office line interface 2 receives this, forms a loop, and responds to office work (301, 30).
2>. Therefore, from the central office line interface 2, CPtJ
6 is notified of the incoming call, and the CPU 6 activates the speech synthesizer 14 via the CPU 1B, controls the incoming call control section 9, and the speech synthesizer 14 informs the caller of the caller's name and the name of the called party. Sends a connection guidance announcement asking questions (
303>.

When this caller replies to the announcement (304
), this voice reaches the incoming call control unit 9, the preprocessing unit 10, and the voice pattern extraction unit 11, as in the case of the registration mode, and the voice pattern extraction unit 11 extracts the voice pattern data of this caller. (305).

At this time, the CPU 6 instructs the comparing and matching section 12 to perform the matching via the CPU 1B, and the comparing and matching section 12 stores the speech pattern based on the speech pattern data given from the speech pattern extraction section 11 in real time. Part 13
Search for and detect whether there is the same voice pattern (
306). At this time, if the same voice pattern is detected, the CPU 6 causes the office line interface 2 to disconnect the caller from the office line and rejects the incoming call (307). On the other hand, if the same voice pattern is not detected, the CPU 6 instructs the terminal interface 4 to call the telephone terminal 7 (308), and detects whether or not the telephone terminal 7 responds (309). If there is a response here, a communication path is formed between the central office line 8 and the telephone terminal, and communication is possible (310
>. On the other hand, if there is no response at the telephone terminal, the CP
U6 controls the voice synthesizer 14 via the CPU 16 to send out the absence guidance announcement (311). The caller who receives this performs a call termination operation (312).

In this way, in this embodiment, by making a call in advance,
You can reject calls from specific callers you have registered. Therefore, in the case of a prank call, etc., the call can be rejected only after the first call.

[Effects of the Invention] As explained above, according to the present invention, it is possible to control whether or not to accept calls from specific persons registered in advance, and to appropriately control the reception of calls from persons below that number. This allows you to talk to only the people you need.
