Description

Voice message service system {VOICE MESSAGE SERVICE SYSTEM}

The present invention relates to a voice internet service, and more particularly, to a voice message service system.

With the rapid development of voice processing technology, voice internet services are also available.

In general, the markup languages used in the voice Internet include VoiceXML 1.0 and VoiceXML 2.0.

In the case of VoiceXML 1.0, voice is synthesized through a <prompt> element or a voice file is provided to a user by executing a pre-recorded audio file through a <audio> element.

In VoiceXML 2.0, voice is synthesized through elements defined in Speech Synthesis Markup Language Specification and <prompt> element, or voice is provided to the user by executing pre-recorded audio file through <audio> element.

This markup language, VoiceXML, enables the use of voice Internet services on a regular phone or terminal.

VoiceXML is abbreviated as VXML, indicating that it is a document format constructed based on XML (eXtensible Markup Language).

The VoiceXML documents that make up the speech application interactively specify how to interact with the user, and the defined tags are used in conjunction with the output of the speech file, the recording of the speech input, speech synthesis and speech recognition techniques.

In general, the VoiceXML gateway that enables the voice Internet service includes a document server 110, a VXML interpreter 120, a VXML interpreter context 130, and an implementation, as shown in the block diagram of FIG. An implementation platform 140 is provided and configured.

The document server 110 is a web server providing a VXML document related to voice and audio. The document server 110 processes a client request and provides a result as a VXML document.

The VXML Decoder 120 requests the VXML to the document server 110 and decrypts the VXML.

Execution platform 140 is controlled by the VXML Decoder Context 130 and requests the VXML element to the VXML Decoder 120 and replays the decrypted VXML from the VXML Decoder 120 according to the user's request. to provide.

Starting from the voice internet, there are active movements to prepare a voice internet voice portal using voiceXML and replace ARS services.

Among the many services that can be applied through VXML, you can consider interworking with an e-mail server. If the VoiceXML gateway and e-mail service can interoperate with each other, you can always check the mail that you have received by phone.

However, there is no way that the VXML Gateway presented in the VXML forum can be used in connection with the existing email server.

Therefore, the message format suggested by RFC 822 (Standard for ARPA Internet Text Message) and the MIME (Multi purpose Internet Mail Extensions) presented by RFC 2045, 2046, 2048, and 2049 are converted to VoiceXML that can be spoken. If there is a way to interwork with a new email server by applying a rule, it is possible to check mail coming from the Internet by telephone and to record voice mail using VXML document written to send mail by voice. If you convert it to an Internet mail format and send it by mail, you will be able to send mail over the phone.

Accordingly, the present invention is to convert the Internet mail to VoiceXML document and to send the Internet mail through the phone or the terminal to check the mail received through the Internet from anywhere through a regular telephone or terminal to improve the conventional problem The purpose is to provide a voice message service system created so that VoiceXML gateway and E-mail server can be interworked.

The present invention provides a VXML decoder for requesting and decrypting a VXML document to a document server to achieve the above object, and requesting a VXML document to the VXML decoder according to a user's request, and playing back the VXML decrypted from the VXML decoder to a user. An implementation platform to provide, a document storage unit for storing VXML documents, a user information storage unit for storing user information, an e-mail data storage unit for storing e-mail data, and an SMTP ( E-mail Message Process (E-mail Message Process) for sending and receiving Internet mail using Simple Mail Transfer Protocol) and a format converter for converting the format between the mail and VXML.

The performance platform is characterized by comprising a DTMF decoder, a speech recognizer, a speech synthesizer and a telephony feature.

The decryptor context connected to the execution platform additionally configures user information management functions.

The format converter includes a Mail2Vxml converter which extracts information such as text, sender, receiver, date, subject, and the like from a mail and converts the information into a VXML document, and a user It is composed of Vxml2Mail converter that converts VXML document containing information to be sent by mail into e-mail document format.

Accordingly, the present invention can convert voice mail into a VXML document and convert the VXML document into an email so that voice mail can be transmitted and received through a general telephone or a terminal.

In FIG. 3, reference numeral 350 denotes a web server for providing a VXML document.

That is, in the exemplary embodiment of the present invention, the VXML server 310 is connected to the VXML server 310 by using the telephone network 320, and the VXML document is requested to the web server 350 while being connected to the VXML server 310. Mail is sent and received using a Mail Transfer Agent (MDA) or a Mail Delivery Agent (MDA).

First, a method of confirming an email by telephone in an embodiment of the present invention will be described with reference to FIGS. 4 to 6.

FIG. 6 illustrates a mail sending process and a process of confirming the mail sent by voice through a phone in an embodiment of the present invention.

When the mail is received by the VXML server 610 via the Internet network 630, the email message processing unit 260 searches the user information storage unit 272 to check whether the mail sender is registered as a user and authenticate the user.

When the user authentication is made in the above, the email message processing unit 260 stores the original mail in the email data storage unit 273 and parses the mail to extract recipient information To.

Thereafter, the email message processing unit 260 includes the path and file name of the original mail stored in the mail data storage unit 273 in the same user information as the recipient among the users registered in the user information storage unit 272. The Mail2Vxml converter 251 constituting the format converter 250 notifies that the mail has arrived.

The Mail2Vxml converter 251 retrieves the original mail from the mail data storage 273 and converts the original mail into a VXML document. The conversion to the VXML document is performed in the process of FIG. 4, and the mail as shown in FIG. 5 (a) is converted into the VXML document as shown in FIG. 5 (b) by the process of FIG.

At this time, the VXML document converted from the mail is stored in the VXML document storage unit 271, and the sender, the mail subject, the time, the VXML document name, and the like are stored in the corresponding recipient area of the user information storage unit 272.

Then, when the mail is received by the above process when the user tries to check the mail that came to him, that is, the user through the telephone network 620 using the mobile communication terminal 641 or the general telephone 642 When accessing the VXML server 610 to check mail, if the VXML document exists, the VXML decoder Context 230 checks the user information from the user information storage unit 272, and if there is a VXML document converted from the mail, the VXML It is taken from the document storage unit 271 and passed to the VXML decoder 220.

Therefore, the VXML decoder 220 interprets the VXML document and voices the mail to the user.

If there is a phone number registered by the user in the user information, the mail received by calling by using the <transfer> element of the VXML element may be serviced by voice.

In addition, the embodiment of the present invention presents a VXML element as shown in the example of FIG. 7 so that a user can send mail by voice using a telephone or a terminal.

In FIG. 7, <voicemail>, <from_address>, <to_address>, <message>, and <cancel> are components for converting a VXML document into an email.

The <voicemail> is a component that notifies the start of recording the voice mail, and has <from_address>, <to_address>, <message>, and <cancel> as child elements. Here, the id attribute represents a name of <voicemail>.

The <form_address> is a component used to receive the sender's email address and has <field> as a child component, and has the attribute of managing the sender's email address in a text format using the <field>.

The <to_address> is a component used to receive the recipient's email address, and has the property of managing the recipient's email address in a text format in the same manner as <form_address>.

The <message> is a component used to record the contents of a mail to be sent by the user, and has <record> as a child component, where the msg_url property indicates url information of a voice file recorded through <record>. Indicates.

The <cancel> is a component for confirming whether or not to finally send mail, and has a <field> as a child component. The <field> determines the value of the cond attribute with a Boolean value of True or false.

Therefore, a process of converting a voice into an e-mail format using the above components will be described with reference to the signal flowchart of FIG. 8.

The user connects to the VXML server 810 using the mobile communication terminal 841 or the general telephone 842, and then sends a mail using DTMF by voice or key press while listening to the voice guided by the VXML server 810. You will be asked.

At this time, the VXML server 810 checks the user's voice or key input to obtain information about the sender and the receiver, and also obtains the mail contents input by the user by voice.

When the information on the sender and the receiver and the voice to be sent by mail are input, when the cond attribute value of <cancel> is 'true', the VXML decoder 220 notifies the VXML decoder Context 230 that the mail is input and the VXML Decryptor Context 230 informs Vxml2Mail converter 252.

If the cond attribute value is 'false', the VXML decoder 220 does not process <voicemail>.

Accordingly, the Vxml2Mail converter 252 converts the information received from the VXML decoder Context 230, that is, the sender and receiver information and the voice mail audio file into an email, and stores it in the email data storage unit 273 and stores user information. The file name of the mail stored in the recipient, date, and email data storage unit 273 is stored in the corresponding user information area.

Subsequently, the Vxml2Mail converter 252 notifies the e-mail message processing unit 260 that there is an outgoing mail, and the e-mail message processing unit 260 retrieves the mail and transmits it to the address of the corresponding recipient.

As described in detail above, the present invention converts an email to a VXML document while interworking with an email server so that a user can check a mail delivered to the user by voice, and also converts a formatted document written in VXML into an email server. By sending it to the receiver through, the user can easily check and send the mail.

In addition, the present invention provides a format converter for converting between a VXML document and an email, and a module for processing an email message, thereby making it easy for a Voice Service Provider (VSP) to construct a voice portal. .
