The present invention relates to a system and method for converting a text written in the form of a short message into a voice and providing the called party. The present invention relates to a text corresponding to the body content of a short message written by a sender to a voice corresponding to a voice designated by the sender. A system and method for converting and transmitting the converted voice to a terminal corresponding to the called telephone number of the short message.

Typical services provided by mobile carriers are voice call service and short message service. Among these, the short message service does not have direct conversation between users like the voice call service, but enables communication between users using text. Such a short message service is inconvenient to communicate with the other party when it cannot be confirmed by the user's time due to the characteristics of the text (for example, the visually impaired) or when it should be provided as a voice message. I can't. In other words, it is desirable to communicate with an audible voice message rather than communicating with the user during driving or visual short message.

On the other hand, in recent years, even a short message that is cheaper than voice calls can facilitate the communication between users, the use of short message service is becoming popular to the public. In line with the popularization of short messages, various portal service companies provide services to create and send short messages through specific web pages or message transmission programs to attract portal site members and actively use portal sites. Providing.

In particular, the short message service through the portal site is in the spotlight because it is possible to reduce the trouble of key button manipulation and various character input of the mobile communication terminal, and people can easily access the portal site through the computer to designate emoticons. It is now possible to write a short message with the content to express.

On the other hand, there is a voice message along with the aforementioned short message as a means for expressing itself to the other party along with communication. In such a voice message service, when a caller accesses the ARS server through his mobile terminal and records the called party's phone number and the voice to be communicated, the ARS server calls the mobile terminal corresponding to the called party's phone number. Play the recorded voice.

However, in the voice message service as described above, the caller has to record the voice that the caller wants to hear directly through the mobile communication terminal, which is annoying to the user. In particular, since the recorded voice is provided to the caller according to the caller's voice, It does not allow users to express their own personality.

Therefore, the caller can enter a message to the called party as if the caller is writing a short message on the portal site without directly recording the voice, and the caller wants to speak to the called party so that the caller can express his or her personality. There is an urgent need for a technology that can be specified and converts a short message into a voice message according to the caller's requirements and provides it to the called party.

The present invention has been proposed to solve the above problems and to meet the above requirements, and converts the text corresponding to the body content of the short message prepared by the sender into the voice corresponding to the voice designated by the sender. It is an object of the present invention to provide a system and method for transmitting the converted voice to a terminal corresponding to a called telephone number of a message.

A system of the present invention for achieving the above object, in the system for converting a text into a voice to provide to the called party, a voice portal that receives the body content of the short message, the incoming telephone number of the short message and voice information from the user terminal server; According to a request of the voice portal server, the body content of the short message is converted into a voice corresponding to the voice information and stored as a voice file in a specific URL, and the V-XML document including the voice file URL and the called telephone number is included. A character / voice conversion server for generating a; And when a call is established with the called party's terminal corresponding to the called phone number while the voice file URL and the called phone number included in the V-XML document received from the text / voice conversion server are checked, the call is stored in the voice file URL. And a V-XML gateway for transmitting voice to the called party's terminal.

On the other hand, in the method of the present invention, in the method of converting the text to speech and providing it to the called party, the voice portal server converts the text content of the short message received from the user's terminal, the incoming telephone number of the short message and the voice information into the text / voice.

The text / voice conversion server 20 is provided with a short message (body content, an incoming call number, a designated voice) written by the caller from the voice portal server 10, and the body content of the short message is adapted to the designated voice. Character / Voice Conversion

That is, the text-to-speech conversion server 20 generates a file (hereinafter referred to as a "speech file") for a voice that converts a text corresponding to the body content into a voice and modulates it into a specified voice. For example, the text / voice conversion server 20 analyzes the grammatical structure of the text input from the text content information and converts the speech into a voice almost similar to a human reading, and then converts the converted voice into various modulation filters, speeds, heights, and the like. A voice file is generated by modulating a voice corresponding to voice information by using a voice modulation method of. This process is commonly referred to as a text / voice conversion process. Then, the text-to-speech server 20 stores the voice file at a specific URL address (hereinafter referred to as "voice file URL").

In particular, the text-to-speech conversion server 20 generates a V-XML document including (inserted) the voice file URL and the called telephone number while storing the voice file in a specific URL. The V-XML document is provided to the V-XML gateway 30, and the V-XML gateway 30 checks the called phone number and the voice file URL through the V-XML document and makes a call to the called terminal. It sends out a voice.

Table 1 below shows a V-XML document.

<? xml version = "1.0" encoding = "euc-kr"?> .. <audio src = "http://vxml.nate.com/vxml/voicefile.wav" /> .. <goto next = "tel : 01012345678 "/> ..

In [Table 1], the voice file URL ("http://vxml.nate.com/vxml/voicefile.wav") is inserted into "audio src" for information on the voice file to be sent to the called terminal. The telephone number ("tel: 01012345678") of the called terminal is inserted into the information (called an outbound call) of the voice file transmission target terminal in the XML gateway 30 in "goto next". The document generation process is defined in the V-XML specification. It inserts the voice file URL information into the V-XML document and the terminal information to be sent to the voice file as well as the <audio src> and <goto next> tags as parameters. It will be easily understood by those skilled in the art that various defined tags may be applied, and thus, a detailed description thereof will be omitted.In addition, the V-XML gateway 30 is used to make a call connection with the mobile communication terminal 50 in the V-XML document. Command for retry count, retry time interval, connection wait time, etc. Boy is preferably further included.

The V-XML gateway 30 includes a well-known V-XML interpreter unit, a signal converter, a telephone interface unit, an ARS unit, and the like, and the V-XML interpreter unit is received from the text / voice conversion server 20. -Translate the XML document to confirm the voice file URL and the phone number information, and the signal converter converts the voice file received as a result of the voice file URL check from the packet signal to the NO.7 signal, and the telephone interface unit A call connection is requested to the mobile communication terminal 50 using the phone number information, and the ARS unit transmits the voice file converted into the NO.7 signal by the signal conversion unit to the mobile communication terminal 50. Detailed description thereof will be easily understood by those skilled in the art, and thus detailed description thereof will be omitted.

Hereinafter, referring to FIG. 2, a method of converting a short message into voice and providing the called party will be described. 2 is a flow chart of one embodiment of a method for converting a short message into a voice designated by a caller and providing the called party.

A user (hereinafter referred to as a "sender") creates a short message through a web page or a message creation program while being connected to the voice portal server 10 by the computer 40 (S100). At this time, the caller inputs the body content and the incoming telephone number, designates the voice to be altered, and then selects the "send button" included in the web page or the message writing program, and then converts the short message into the corresponding voice to the called terminal. Requires to be sent.

Accordingly, the voice portal server 10 transmits the text content, the called phone number, and the designated voice inputted by the caller to the text / voice conversion server 20 to request text / voice conversion (S101).

Then, the text-to-speech conversion server 20 analyzes the text content received from the voice portal server 10 to voice convert the text and voice modulates the voice into a specified voice (S102). Then, the text-to-speech conversion server 20 generates a file for the modulated voice and stores the voice file in a specific URL (S103).

Then, the text-to-speech conversion server 20 generates a V-XML document including the voice file URL and the incoming telephone number received from the voice portal server 10 while storing the voice file in a specific URL. (S104).

Then, the text-to-speech conversion server 20 forwards (delivers the generated V-XML document in the sense of a command to send the voice stored in the voice file URL to the called phone number to the V-XML gateway 30). (S105).

Accordingly, the V-XML gateway 30 translates the V-XML document received from the text-to-speech conversion server 20 to confirm the voice file URL and the called phone number (S106).

Then, the V-XML gateway 30 recognizes the mobile phone terminal number as a result of translating the incoming phone number to the corresponding mobile communication terminal 50 through a gateway exchange, a mobile communication exchange, etc. belonging to the mobile communication network. Make a call connection request (S107). On the other hand, the V-XML gateway 30, if the landline telephone number as a result of translating the incoming telephone number, makes a call connection request to the corresponding landline telephone through a gateway exchange, a landline telephone exchange, etc. belonging to the wireline communication network, and such a call. The connection process will be readily understood by those skilled in the art. In addition, if the call connection fails, the V-XML gateway 30 determines whether the call connection in the V-XML document corresponds to the number of retries, retry time intervals, and connection wait times. 50) it is preferable to proceed with the call connection process.

During the process of "S107", the V-XML gateway 30 checks the voice file URL, accesses the text / voice conversion server 20, and receives the corresponding voice file (S108 and S109). Here, the voice file stored on the text-to-speech server 20 is transmitted in packet units when transmitted from the text-to-speech server 20 to the V-XML gateway 30. Therefore, the voice file is transmitted by a packet signal and needs to be converted in order to transmit it back to the mobile communication network.

Accordingly, the V-XML gateway converts the voice file from the packet signal to the NO.7 signal (S110).

Subsequently, when receiving a response to the call connection from the mobile communication terminal 50 through the mobile communication network (S111), the V-XML gateway 30 converts the voice in the state of establishing a call with the mobile communication terminal 50. The signal is sent to the mobile communication terminal 50 (S112).

On the other hand, if additionally the pre-listen menu is selected on the web page for the short message created in step S100 (short message creation step) from the caller, the voice portal server 10 sends the short message to the text / voice conversion server 20 Requests a voice file converted from the body content of the corresponding voice and provides it to the computer 40.
