Description

The present invention relates to an auto call system, and more particularly to a server access type auto call system that sends an automatic message to a subject via a server.

In recent years, in the voice/telephone service business, an auto call system has been adopted to notify the user by automatic voice of reminders for unpaid persons, confirmation of reservation status with customers, advance delivery guidance of a courier, etc. 1). There, the client sends data such as a list of callees, execution date and time of autocall, and a document in which notification contents by automatic voice are recorded to the server via the Internet.

In a server equipped with an IVR (Interactive Voice Response) function, a TTS (Text to Speech) function, a SIP (Session Interaction Protocol) function, etc., a notification document is converted into voice data by voice synthesis processing, and the public telephone network (PSTN) is used. Alternatively, it makes a call (call) to the telephone of the target person through the IP network. When the target person picks up the telephone and enters the connection (call) state, the target person is automatically voice-guided by synthetic voice.

Generally, a person hesitates to put into a call state (connect) when a call comes from a person whose telephone number starts from an area code number that is unfamiliar. This is because it is determined that the call is a wrong call or a party (information from a service provider) that has little relationship with itself. In particular, the call is likely to be rejected due to the caution of malicious calls such as special fraud.

When making an automatic voice message, when a call is received at the telephone of the subject, the telephone number of the caller is usually displayed on the display unit of the telephone. However, if the target person sees the displayed telephone number and determines that he/she is a stranger, a suspicious person, etc., he/she will be refused to answer the phone and the message cannot be delivered to the target person.

Therefore, there is a need for an autocall system and method that ensures that the subject of the autocall picks up the call.

An auto call method in an auto call system of the present invention is an auto call method for an auto call system for connecting to a plurality of clients via a network, and an auto call received from an auto call instruction client (hereinafter referred to as an auto call instruction client). Based on the information, the data of the telephone number of the target person and the data relating to the call origination are transmitted to the voice communication device of the auto call instructing client or the voice communication device of the other client instructing the auto call among the plurality of clients . As a result, the voice communication device connected to the public telephone network or the IP network makes a call to the telephone set (to which the telephone number is assigned) corresponding to the above telephone number (herein referred to as the target telephone set). Then, when a call is established with the target telephone, the automatic voice call data is transmitted to the voice communication device. As a result, the voice communication device makes an automatic voice call with the target person. The voice communication device can be composed of a voice gateway.

As a result, the voice communication device having the same area code as that of the subject telephone can be used for calling, and the subject can notify the message of the client without rejecting the call. For example, the voice communication device has an area code (area code) to which the auto call instruction client belongs, and is composed of a voice communication device connected to a public telephone network or an IP network.

The voice communication device may have the telephone number of the area code to which the auto call instruction client belongs, or the voice communication device may have a telephone number of another area code different from the area code to which the auto call instruction client belongs. It is possible to have.

For example call-system can be connected to a plurality of clients by closed area network. Then, the data of the telephone number and the call data can be transmitted to the subordinate client subordinate to the auto call instructing client and designated by the auto call instructing client. As a result, the voice communication device having the subordinate area code to which the subordinate client belongs and connected to the public telephone network or the IP network makes a call to the target telephone corresponding to the telephone number having the subordinate area code.

It is also possible for the voice communication device to own multiple caller telephone numbers. For example, the data of the caller telephone number selected by the auto call instruction client can be transmitted to the voice communication device. As a result, the call is made to the target telephone by the caller telephone number selected by the auto call instruction client.

When a call is established with the target telephone, the voice synthesis processing can convert the data of the automatic voice document into voice data and transmit the voice data to the voice communication device. Since the content of the voice synthesis process differs depending on the language, the voice synthesis process for Japanese or the voice synthesis process for foreign language may be executed according to the language designated by the auto call instruction client. The client's designated language can be determined by the difference in language format (difference between sites, etc.) when instructing auto call, the language information included in the auto call information, and the like. Alternatively, the recorded voice data can be transmitted to the voice communication device when a call is established with the target telephone.

The auto call system of the present invention is an auto call system that connects to a plurality of clients via a network, and includes a call control unit and an auto call control unit that controls the call control unit to make a call and make a call. The call control unit , based on the auto call information received from the auto call instruction client , provides the data of the telephone number of the target person and the data related to the calling by the voice communication device of the auto call instruction client or the auto call instruction client of the plurality of clients. Send to the voice communication device of another specified client . As a result, the voice communication device connected to the public telephone network or the IP network makes a call to the target telephone corresponding to the telephone number. Then, the call control unit transmits the automatic voice call data to the voice communication device when a call state is established with the target telephone. As a result, the voice communication device makes an automatic voice call with the target person.

The program of the present invention is an auto call system for connecting to a plurality of clients via a network , and when an auto call designated date and time comes, an auto call received from an auto call instruction client from a voice communication device connected to a public telephone network or an IP network. In order to make a call to the target telephone corresponding to the above telephone number included in the information, the data of the telephone number of the target and the data related to the call are transferred to the voice communication device of the auto call instruction client or a plurality of clients. In the step of transmitting to the voice communication device of the other client specified by the client who issued the auto call instruction, and when the call state is established between the target phone, the voice communication device makes an automatic voice call with the target person. And sending the automatic voice call data to the voice communication device.

The document data describing the contents of the automatic voice may be converted into a synthetic voice by a voice synthesis process, or may be a recorded voice or a combination of a synthetic voice and a recorded voice. Further, the auto call system may be connected to a plurality of clients through a closed network and data such as auto call information may be mutually communicated, or the auto call system may create auto call information. For example, by receiving the telephone number of the target telephone and the automatic voice document from the client directly on the system side, or by receiving it through the network, the target side is simultaneously broadcast to the target person through the telephone communication network owned or used by the system side. It is possible to

On the other hand, an auto call method in another aspect derived from the viewpoint of speech synthesis processing is either the first speech synthesis processing for Japanese or the second speech synthesis processing for foreign language, depending on the language specified by the client. One of the processes is executed to convert the document data corresponding to the text describing the contents of the automatic voice into voice data, and the automatic voice call is performed based on the generated voice data. The speech synthesis process in one language may be executed for one person who is to be called automatically, or the designated language may be switched and selected in the middle.

As a result, the message can be notified to the target person (for example, a foreigner) who has difficulty hearing the Japanese voice guidance. In addition, it is possible to construct a system that executes either the first voice synthesis process for Japanese or the second voice synthesis process for foreign language in an auto call system including a call control unit and an auto call control unit. Yes, for example, a call control unit for Japanese and a call control unit for foreign language are provided. Alternatively, one call control unit may be equipped with voice synthesis processing engines of different languages.

Such an auto call method and auto call system may be connected to a client through a closed network to send and call the auto call information, or the auto call system side may be the main input/output of the auto call information. It may be performed. The configuration of the auto call system, the exchange of auto call information from the client, the connection configuration with the client, the configuration for making a telephone call, etc. are arbitrary, and a plurality of electric field numbers described above may be selected.

The client's designated language may include language information in the auto call information created by the client, or prepare a format for client creation such as an auto call reservation screen for each language and regard it as the client's designated language. Can also Further, the language may be automatically determined on the auto call system side. For example, it is possible to make a selection based on the family register information (whether or not the family register is held) of the person who is the target of the auto call, and the like.

During the call with the target person, the first voice synthesis process and the second voice synthesis process may be switched according to the response from the target person. For example, it can be configured to switch when a response (tone signal or the like) is received from the target person for personal identification. In this case, the call control units for Japanese and foreign languages may be switched, or the voice synthesis processing engine (software) may be switched.

As described above, according to the present invention, the target person can be surely notified by telephone in the auto call system and the method thereof.

It is the figure which showed the structure of the auto call network system containing an auto call system and a client. It is a block diagram of an auto call system and a client. It is the figure which showed the data communication at the time of performing an auto call between an auto call system, a client, and a subject. It is a flowchart of the automatic call reservation setting performed in the PC arranged in the section of the client. It is a flow chart of auto call control processing performed in an auto call server.

Hereinafter, an auto call system according to the present embodiment will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration of an auto call network system including an auto call system and a client.

The auto call system 10 includes an auto call server 20 and a call control server 30, and is connected to a plurality of clients 100, 200, 300,... Via a network. Here, the plurality of clients are clients who are the administrative body, and more specifically, are constituted by municipalities such as city halls and town halls.

The client 100 includes a router 120, a gateway 140, and a personal computer (PC) 160, and is connected to the auto call system 10 by a VPN (Virtual Private Network) which is one of closed networks. That is, the client 100 can mutually communicate with the auto call system 10 with the PC 160. Other clients are similarly connected to the auto call system 10 by VPN.

A plurality of clients 100, 200, 300,... Which are local governments such as municipalities are located in areas to which different area codes (area codes) are assigned. Here, for convenience, the area code of the client 100 is “00”, the area code of the client 200 is “01”, and the area code of the client is “02”. On the other hand, the client 100' is a client designated by the client 100 as a call origination location, and includes a router 120' and a gateway 140'.

The auto call system 10 can provide an auto call service to each client. Specifically, people such as taxpayers' non-payers of tax and public dues and people subject to health examination can call all at once at a designated date and time and notify them by automatic voice. Each client creates in advance information (auto call information) including document data in which the content of the automatic voice is written, the telephone number of the person who is subject to the auto call, the date and time when the auto call is executed, and sends it to the auto call system 10. ..

FIG. 2 is a block diagram of the auto call system 10 and the client 100. In addition, although the client 100 will be described below as a target, other clients have the same configuration.

The auto call system 10 includes an auto call server 20, a call control server 30, a switch circuit 40, and a router 50. The auto call server 20, which is supplied with power from the power source 62, controls the call control server 30 to issue a telephone call and an automatic voice call instruction at a predetermined timing. The call control server 30 includes a first call control server 30A that supports Japanese automatic voice, and a second call control server 30B that supports foreign language (English here) automatic voice. A program relating to the execution of the auto call is recorded in advance in a memory (not shown).

The first call control server 30A and the second call control server 30B, which are supplied with power from the power source 64, generate synthetic voice by voice synthesis processing and exchange control signals (signals) to make and receive calls. Controls for making voice calls with the target person such as calls and line connections and disconnections.

The switch circuit 40 sends the data sent from the client 100 via the router 50 to the auto call server 20 or the first and second call control servers 30A and 30B. The signals output from the first and second call control servers 30A and 30B are output to the outside of the system via the ONU 60 which is a terminal device.

The auto call system 10 is connected to the client 100 by the PVN that functions as a dedicated network that is not interfered by a third party as described above, and the router 120 of the client 100 is specified in the auto call system 10. Also, packet communication by encryption is performed according to the IPsec method.

The router 120 of the client 100 receives the data from the auto call system 10 via the terminal device 110, and distributes the data to the personal computer (PC) 150, the gateway 140, and the like. The gateway 140, which is connected to the public telephone network (PSTN) and functions as a voice communication device, transmits the data (signal) and the voice data regarding the call origination (hereinafter, also referred to as a call) sent from the call control server 30 to the PSTN. Convert to the corresponding data. The call to the telephone of the target person and the automatic voice call with the target person are performed based on the data relating to the call sent from the call control server 30 of the auto call system 10 to the client 100 and the automatic voice call data, respectively. Done.

The client 100 performs different tasks in the sections 100A and 100B. For example, the section 100A corresponds to the health insurance fee collection section, and the section 100B corresponds to the health support section. The section 100B includes a personal computer (PC) 150 similar to the section 100A.

The client 100 is located in a place belonging to the area code 01, and accordingly, the gateway 140 is assigned a telephone number including the area code 01 at the head. Further, the gateway 140 owns a plurality of telephone numbers and can switch the telephone number of the caller to make a telephone call. By sending the selected or designated telephone number to the client as the caller telephone number, the caller's telephone number is displayed on the telephone of the target person when the call is received. Here, the sections 100A and 100B are configured to call with different telephone numbers.

The client 100' is a client subordinate to the client 100, and receives data relating to an outgoing call and an automatic voice call from the call control server 30 through the terminal device 110'. The gateway 140' is capable of making a call and making an automatic voice call through the PSTN.

FIG. 3 is a diagram showing data communication at the time of executing an auto call between the auto call system 10, the client 100, and the telephone recipient. The same data communication is performed in other clients.

In the client 100, information such as health insurance collection and health examination regarding the residents of the client 100 is stored in the data management system 190, and the data management system 190 is not connected to a network accessible by an unspecified external person. .. Further, the computers 160 and 150 installed in the section 100A and the section 100B of the client 100 are also not connected to the data management system 190.

The operator belonging to the section 100A of the client 100 creates the auto call information using the PC 160. The operator loads the portable memory DM in which the destinations of the auto-call target persons such as the delinquent list are recorded into the PC 160 and reads the data. Data stored in the data management system 190 is recorded in the portable memory DM.

The operator opens a screen (site) for inputting the operation contents of the auto call, specifies an auto call execution date and time, and inputs a document of an automatic voice scenario (script). Further, a calling telephone number for making a call is designated and selected. Data of auto call information including these contents is created, for example, as a CSV file and uploaded to the auto call system 10. Such auto call information created on the client side can also be created in section 100B.

The auto call system 10 transmits data relating to a call to the client 100 according to the designated auto call date and time. The gateway 140 sequentially makes a call to a target person (a delinquent person or the like) of the auto call through the public telephone network (PSTN). At this time, the gateway 140 makes a call using the telephone number of the section that executes the auto call. The IP network and the gateway 140 may be connected.

When the subject's telephone A1 enters the incoming call (incoming) state and the subject picks up the telephone, an automatic voice call is made based on the synthesized voice data sent from the auto call system 10. When the automatic voice call by the telephone set A1 is completed, a call is made to the next telephone set A2 to make a call. The telephone sets A1 and A2 of the target person may be fixed telephones or mobile telephones.

When an automatic voice call is made to the target person in this way, since the call is made from the gateway 140 installed in the client 100, the telephone numbers starting with area code 01 are displayed on the displays of the target telephone sets A1 and A2.

By the way, when the client 100 is an administrative system such as a local government, there are various people who receive auto call, such as non-payment of taxes and other public dues, those who plan to undergo medical examination, etc. To be done. That is, the person who lives in the area under the jurisdiction of the client 100 becomes the target person for auto call. Therefore, when the display of the telephone number of the client 100 is viewed on the own telephone, the person who is subject to auto call recognizes that the telephone is from the same local government or a neighboring local government having the same area code.

Generally, a person hesitates to put into a call state (connect) when a call comes from a person whose telephone number starts from an area code number that is unfamiliar. This is because it is determined that the call is a wrong call or a party (information from a service provider) that has little relationship with itself. In particular, the call is likely to be rejected due to the caution of malicious calls such as special fraud.

On the other hand, when a telephone number starting with the same area code number as the local government in which one lives is displayed, even if the telephone number of the client 100 is not recognized (the telephone is from the city hall), it is possible to identify itself in daily life. It is assumed that the call is from a related one (for example, an administrative service such as a beauty salon or a library), and there is not much obstacle in making a call while connected.

Therefore, when a telephone call is made from the gateway 140 of the client 100 and the target telephone set A1 enters the incoming call state, the target person receives the telephone call and goes into a call state, whereby an automatic voice call using synthetic voice is started. As a result, the subject will confirm the message from the client 100.

On the other hand, among the target persons, there is also a person who, when receiving a call from the client 100, makes a call to the client 100 such as confirming detailed contents. As described above, since the call is made with the telephone number of the section that executes the auto call, the person in charge of the section is directly connected to the telephone.

Further, the client 100 can specify the client 100' having the gateway 140' to make a telephone call. For example, when the client 100 is born by the merger of two adjacent cities, the area code assigned to the old city remains. The client 100 can make a call from the gateway 140' by including the instruction data relating to the call from the gateway 140' in the auto call information. If the client 100 is a government-designated city, an area code may be assigned to each ward in the city. Even in such a case, the call can be transmitted from the gateway owned by the client having the telephone number of the area code of the area where the target person lives.

For example, when making an auto call to a target person who lives in an old city with an area code of "10," the area code of the other old city that did not live, "00", The area code "10" is familiar. Therefore, by making a call from the gateway 140 ′ to the target person who lives in the area corresponding to the area code “10”, it becomes easy to achieve the call state.

FIG. 4 is a flowchart of the auto call reservation setting process performed in the PC 160 arranged in the section 100A of the client 100. The operator of the section 100A performs an input operation on the auto call reservation site provided by the auto call system 10. The same reservation setting process can be performed on the PC 150 of the section 100B.

The setting screen for auto call reservation is a screen display for inputting an automatic voice scenario (script), and a frame for inputting intro guidance, ending guidance, question guidance, etc. is displayed. The operator writes the notification content document in those guidance frames. For example, in the intro guidance, enter "This is the city hall..."

Following that, there is also an intro guidance frame in which you can enter a scenario to confirm your identity, and in the case of yourself, please press the * (rice) button and "1" on your phone. If not, please hang up. It is possible to write a document such as "...". In addition, the operator designates the date and time (for example, the time zone in the morning of a holiday) on which the auto call is executed on the screen, and the telephone corresponding to his or her section is selected from a plurality of telephone numbers that can be called by the gateway 140. Specify the number. Furthermore, when making a call from the client 100', an operation of selecting a gateway to be a device to be called is performed. The operator performs necessary input operations such as document input, date and time designation, and caller telephone number designation.

On the other hand, when setting an automatic call reservation, it is configured so that an automatic call can be performed even for a person who has difficulty communicating in Japanese. For example, if a foreigner resides in the area under the jurisdiction of the client 100 for business purposes for a long period of time (when registered as a resident), it is desirable to use autocall because it cannot be read even if a notification is given in writing. I cannot understand the speech even if I send an automatic voice message in words. For such a target person, an automatic voice call is made in a foreign language (English).

By the way, since the alphabet can be naturally input in the input section (keyboard) of the PC 160, an English scenario document can be created even on the auto call reservation setting screen for Japanese. However, the synthesized speech obtained by the speech synthesis processing for Japanese is a synthesized speech based on the pronunciation and intonation peculiar to Japanese people only, so even if a native foreigner hears the synthesized speech, the content will not be understood. difficult. For example, when the alphabet "Water" is input on the Japanese setting screen, the sound is pronounced as "water" in katakana notation. However, the native pronunciation is similar to "Waller" in katakana notation.

That is, even if automatic voice in English is performed using the first call control server 30A having a voice synthesis processing function for Japanese, it is converted into a synthetic voice of Japanese pronunciation (which cannot be listened to natively) and intonation. I will end up. Therefore, for a person who cannot understand Japanese speech, it is necessary to perform automatic English speech based on the second call control server 30B having a speech processing function for foreign languages.

On the PC 160, it is possible to switch between and display a site displaying a Japanese input screen and a site displaying an English input screen. In the case of English screen display, enter "This is the City Hall of..." in English in the intro guidance frame. The operator switches the input screen according to the target person. Here, the destination lists of the target person who sends the automatic voice in English and the target person who sends the automatic voice in Japanese are separately recorded in the portable memory DM, and the operator selects the type of the destination list data. Switch the input screen based on.

When the automatic call reservation setting screen of the language designated by the operator is displayed (S101 to S104), the operator performs an operation of inputting a scenario document. Then, when the reservation execution operation is performed (S105), the list data, the document data of the scenario, the auto call designated date and time, and the data of the auto call information regarding the caller telephone number are uploaded. At the same time, the reservation completion screen is displayed on the PC 160 (S106).

FIG. 5 is a flowchart of the auto call control process executed by the auto call server 20.

When the auto call information is received from the client, the execution of the auto call by the call control server according to the designated language is set, and the standby state is set (S201 to S204). That is, of the first call control server 30A for Japanese and the second call control server 30B for foreign language, the auto call is set by the call control server of the language corresponding to the reservation setting screen on which the input operation is performed. ..

When the designated date and time for the auto call comes (S205), the call control server corresponding to the designated language transmits the data of the telephone number of the first target person in the destination list and the data regarding the transmission to the client 100 (S206). The gateway 140 makes a call (outputs a signal) to the target telephone by the caller telephone number specified by the operator based on the telephone number data of the target person. When performing an auto call to a target person whose telephone number has the same area code as the area code “10” of the client 100′, the IP address of the gateway 140′ is specified, and the telephone number data and the data related to calling are displayed. , To the gateway 140' of the client 100'. When the gateway 140' has a plurality of telephone numbers, it is possible to select the telephone number when making an automatic call reservation.

When the telephone of the target person receives a call and becomes in a call state (S207), a voice synthesis process for converting document data into voice data is performed (S208). The speech synthesis processing here is performed by a corpus-based speech synthesis (CTTS) method. Specifically, a prosodic model required for speech synthesis and a speech database are created in advance by a speech corpus construction technique, and prosodic information is estimated from the analysis result of text data (scenario document data) using the prosodic model, A set of phoneme waveforms that best match the information is selected from the speech database to obtain a synthetic sound. As a result, it is possible to perform automatic speech with expressive voice having the same feeling as the human voice.

When the call ends, the data of the auto call execution result such as the call time, the call time, and the reason for disconnecting (call disconnection, no answer, etc.) at that time are collected and recorded in the auto call server 20 (S210). In addition, confirmation information (lost payment slip, account transfer request, etc.) included in the tone signal sent by the response operation of the subject is also collected.

When the call ends for one target person, the call is made to the next target person. Steps S206 to S209 are repeated until the call to all the recipients in the destination list is completed. If the subject does not respond even after making a call for a certain period of time, the call is forcibly disconnected and the call is made to the next subject.

After the completion of the auto call to all the target persons, the operator can download the auto call execution result (transmission result) information from the client 100. When there is a download request, the auto call system 10 transmits the recorded auto call execution result data to the client 100. The client can analyze the response rate of the subject based on this data.

As described above, according to the present embodiment, in the auto call system 10 connecting to the client 100 by the VPN, when the auto call information is received from the client 100 and the designated auto call date and time comes, the telephone number of the target person in the destination list is reached. And the data relating to the telephone call are transmitted to the client 100. The gateway 140 of the client 100 makes a call to the telephone of the target person so that the telephone number designated by the operator becomes the caller telephone number. When the target person answers the call and enters a call state, the document data of the scenario is converted into voice data by voice synthesis processing, and a call is made by automatic voice.

Since the connection between the auto call system 10 and the client 100 is a closed network, even if the carrier is not a telecommunications carrier having a large-scale telephone network covering the whole country, auto call for preventing information leakage to a third party The system can be built. On the other hand, by making a call from the gateway 140 equipped with the voice communication function owned by the client 100 instead of the auto call system side, the telephone number of the same area code (area code) is displayed on the telephone of the target person, Opportunity for the target person to answer the phone is enhanced.

In particular, in order to inform the target person of the telephone number according to the section of the client as the calling telephone number, the target person calls the client who is the auto caller by the calling telephone number for confirmation items, questions, etc. after receiving the auto call. If a function of transferring to a telephone installed on the desk of a person in charge is provided by a service of an external communication carrier, the person directly in charge of the section that has executed the auto call is connected. Therefore, the client does not have to find the person in charge who requests the person in charge in the client or the section, and the person in question can immediately find out what he/she wants to hear from the person in charge.

Instead of separately preparing the auto call reservation setting screens for Japanese and foreign languages, the language may be selected on one reservation site. Further, the destination list does not have to be divided into lists for foreign languages and Japanese. In this case, create scenario documents for Japanese and foreign languages in advance and make an automatic call reservation.At the same time, automatically determine whether the name is a Japanese name or another name based on the name in the recipient list, and when performing an automatic call. It suffices to perform speech synthesis processing in a language corresponding to the target person. For example, it is possible to make a judgment based on family register information and send a message by an automatic voice in a foreign language.

On the other hand, when an automatic voice message in the language specified by the client is played, a message that allows the language to be selected and specified is played, and the voice synthesis processing is switched according to the response (tone signal, etc.) from the target person. May be. For example, in the intro guidance, the voice synthesis process for Japanese and the voice synthesis process for foreign language are continuously executed for the document data of the same content, and the automatic voice call between Japanese and foreign language is continuously performed. Then do. At this time, only the number of the message "・・If applicable, please press the number..." is set to different numbers for Japanese and foreign languages. Accordingly, it is possible to make a call by a Japanese voice synthesis process or a foreign language voice synthesis process according to the number (tone) that the subject responded to.

It is also possible to first send an automatic voice message in a foreign language (or Japanese) voice synthesis process and switch to a Japanese (or foreign language) voice synthesis process in response to a response. In this case, it is also possible to configure a single call control server having both Japanese and foreign language speech synthesis processing functions (engines). The number of languages is not limited, and a voice synthesis processing unit for Chinese, Korean, Spanish, German, French, etc. may be provided.

In this embodiment, the caller telephone number of the gateway is switched for each section, but a plurality of caller telephone numbers may be properly used in the same section. For example, if the target person is a Japanese person and the target person is a foreigner, it is assumed that the target person will make a call after performing an auto call, and make a call from a gateway with a different caller telephone number. Good. This enables the target person to have a direct conversation with a foreign operator in a language other than Japanese, such as English. Also, the caller telephone number may be selected and set across a plurality of sections.

In the present embodiment, the client is described as a local government at the municipal level, but it is a local government at the prefectural level, public bodies related to the country, public corporations such as universities, high schools, etc., religious corporations, special corporations, and Is also effective for clients such as private companies that perform voice service business.

For example, when carrying out an election advertisement, a questionnaire, a service guide, etc. by an auto-all system, it is necessary to make a telephone call not to a specific area but to the area of the whole country. Even in this case, if a telephone number having an area code that is unfamiliar to the local residents is displayed as the caller, the connection may be refused. Therefore, it is desirable to make a call using a telephone with an area code for each particular area.

For example, if the voice service company is in Tokyo and wants to perform auto call for people who live in Nagoya and Osaka, specify the client that installed the gateway installed in Nagoya and Osaka, The client may make a call or make a call by call control by the call control server. In this case, the remote client and the auto call system may be connected by a closed network.

Alternatively, a medium such as a memory containing the auto call information may be received from the client, or the server side may create the auto call information in response to the client's intention and make a telephone call. Further, when notifying all of the target persons of the same message content (such as election advertisement), automatic voice guidance may be provided by recorded voice instead of generating synthetic voice by voice synthesis processing.

For the selection and switching of Japanese speech synthesis processing and foreign language speech synthesis processing, the client operates the cloud service etc. in-house (the phone such as the gateway is set on the auto call system side) to the auto call system. It can also be applied. It is also possible to install a voice communication device other than the gateway, and the connection with the client may be a computer (workstation or the like) other than the PC.
