Create video character management information. In the selection of a video character, the purchaser shall add a base character set consisting of at least two images (e.g., a mouth-opening video and a mouth-opening video for the same video character) and an additional character set (e.g. dancing) associated with a particular motion. May select a series of consecutive images related to the dancing motion corresponding to the shape change item. In this case, the character identification information is associated with the additional character set additionally selected by the buyer in addition to the basic character set of the specific image character selected by the buyer. Meanwhile, the image character is produced as a still image such as a bitmap file or a video such as an MPEG and stored in the storage unit 220 and then stored in the storage unit 220 of the sender's terminal device 100, the receiver's terminal device 130, and / or the sender. May be transmitted to the communication device 140. In this case, if the buyer selects a large number of additional character sets, there may be problems such as lack of storage space and increased transport traffic. Therefore, in order to solve this problem, it is necessary to produce video characters in the form of a relatively small flash file. desirable.

Here, the purchaser is a user who uses the video character provided by the voice call providing system 110 using the character according to the present invention for free or free of charge and thus plays a role of a substantial caller in connecting the voice call with the receiver later. Mark as a sender. Meanwhile, the caller's communication device identification information includes at least one of a MAC address (or IP address) of the caller's communication device 140 and a telephone number assigned to the caller's communication device 140. In addition, the voice call connection method is set to one of the socket communication method and the callback call communication method in response to the caller's communication device identification information.

The storage unit 220 stores the image character management information generated corresponding to each caller. In addition, when a voice call is connected between the communication device 140 of the caller and the terminal device 130 of the receiver, the storage unit 220 selects an image character selected by the caller to the communication device 140 of the caller and the terminal device 130 of the receiver. And stores an application program for performing an operation of changing the shape of the video character selected by the caller output to the terminal device 130 of the receiver in synchronization with the voice data section of the voice call connected between the caller and the receiver.

The character transmitter 230 provides the video character to the caller's terminal device 100 so that the caller can check the video character selected by the caller at the time when the caller purchases the video character. In addition, the character transmitter 230 reads an image character corresponding to the character identification information from the storage unit 220 when the character identification information uniquely assigned to the image character selected by the sender is received from the terminal device 130 of the receiver. And transmits to the caller's communication device 140 and the receiver's terminal device 130 corresponding to the caller's communication means identification information. In addition, when receiving the character identification information uniquely assigned to the video character selected by the sender from the terminal device 130 of the receiver, the character transmission unit 230 is selectively called by the sender terminal device 100 used by the sender when purchasing the video character. The video character corresponding to the character identification information is transmitted. Accordingly, when the video character is purchased using the computer as the terminal device 100 of the caller and the cellular phone is set as the communication device 140 of the caller, when the receiver requests voice call connection, The video character is output so that the caller can control the video character more conveniently.

The call connection unit 240 is the caller's communication device 140 and the receiver based on the caller's communication means identification information included in the caller's video character management information corresponding to the character identification information received from the receiver's terminal device 130. The voice call is connected between the terminal device 130. To this end, the call connection unit 240 includes a socket control unit 242, a call control unit 244, a callback call control unit 246 and a call relay unit 248. The socket controller 242 and the call controller 244 are components for providing voice communication between the caller's communication device 140 and the receiver's terminal device 130 without the intervention of the callback server 120. 246 and the call relay unit 248 are components for providing voice communication between the caller's communication device 140 and the receiver's terminal device 130 when the callback server 120 is involved. Therefore, when the voice call connection method included in the video character management information is set to the socket communication method, which is a direct connection method between the sender's communication device 140 and the receiver's terminal device 130, the call with the socket control unit 242 is performed. The voice communication service is provided by the control unit 244, and the voice communication service is provided by the callback call control unit 246 and the call relay unit 248 when the voice call connection method is set to the call back call communication method.

At this time, the callback call control unit 246 requests the callback call connection to the caller's terminal device 100 by transmitting the call number and callback call connection conditions assigned to the caller's communication device 140 to the callback server 120. . The callback call connection condition is a short message connection for transmitting a short message to the caller's communication device 140, in which a phone number assigned to the callback server 120 is set as caller identification information, and a phone number given to the callback server 100. Sending to the communication device 140 of the caller includes a callback request connection requesting a callback call.

The program provider 250 reads an application program from the storage 220 and transmits the character program to the terminal device 130 of the receiver that has transmitted the character identification information. The application program transmitted to the terminal device 130 of the receiver has an auto-install function and is automatically installed in the terminal device 130 of the receiver. At this time, the program providing unit 250 checks whether the application is installed on the receiver terminal device 130 and the version of the installed application before transmitting the application. If the application program is not installed in the terminal device 130 of the receiver or the installed application program is an old version, the program provider 250 transmits the application program to the terminal device 130 of the receiver. Such an operation of the program provider 250 is preferably performed whenever the character identification information is received from the terminal device 130 of the receiver.

The operation of the program provider 250 is performed in the same way with respect to the communication means 140 of the sender. At this time, the functions of the application program installed in the caller's communication device 140 are the shape change function of the video character and the control function of the video character. The shape change function of the video character is a function of changing the shape of the character in synchronization with the caller's voice section, which is the same as the function performed in the terminal device 130 of the receiver. On the other hand, the control function of the video character is a function of receiving a pattern desired by the caller from among the specific change patterns set in advance in connection with the shape change of the video character such as winking or dancing. For example, when the caller selects the shape change menu on his communication device 140, a selectable shape change item is output to the output means of the caller's communication device 140 in correspondence with the identification number. If the caller inputs the identification number corresponding to the desired shape change item, the application program installed in the caller's communication device 140 transmits the identification number corresponding to the shape change item selected by the caller, and the receiver's terminal device ( The application program installed at 130 outputs an image character corresponding to the identification number corresponding to the received shape change item to the output means.

The voice data management unit 260 stores the voice data flowing from the caller's communication device 140 in the storage unit 220 in correspondence with the character identification information, and terminates the voice call among the voice data stored in the storage unit 220. Later, voice data corresponding to the character identification information received from the terminal device 130 of the receiver is read and transmitted to the receiver terminal device 130. At this time, the character transmitter 230 reads out an image character corresponding to the character identification information received from the storage unit 220 and transmits the image character to the terminal device 130 of the receiver, and the terminal device 130 of the receiver is received. The video character is deformed in synchronization with the voiced sound section of the voice data received from the voice data manager 260.

The communication unit 270 provides a means for transmitting and receiving data with the terminal apparatus 100 of the caller, the callback server 120 and the terminal apparatus 130 of the receiver. The communication unit 270 supports multicasting and socket communication, and accommodates various protocols such as TCP / IP and UDP.

At this time, the language model storage unit 530 is optionally provided, the voice communication apparatus according to the present invention may be configured to output the candidate phoneme or candidate words obtained through the speech pattern recognition as a recognition result. The speech recognition method applicable to the present invention is a speech recognition method using a recognition model (for example, Dynamic Time Warping, Hidden Markov Model, Hidden Markov Network, Artificial Neural Network, etc.), a search method using a language model (for example , Finite State Network, Word-pair, N-gram, etc.) and parsing methods for recognized sentences (Context-Free Grammar, Chart parser, etc.). Such a voice recognition method is a matter well known to those of ordinary skill in the voice recognition field, so a detailed description thereof will be omitted.

The operation controller 540 reads and outputs an image character corresponding to the recognized voice from the set of image characters stored in the storage unit 410. At this time, the selection of the video character set by the operation control unit 540 depends on the type of audio recognition by the audio recognition unit 510. That is, the voice recognition unit 510 is set to recognize the basic collection (eg, 'word', 'right', 'yi' included in each syllable based on phoneme recognition). If so, the operation controller 540 selects an additional character set composed of image characters corresponding to each vowel from the character sets stored in the storage unit 410, and among the image characters constituting the additional character set. Reads and outputs the image character corresponding to the recognized vowel. On the contrary, if the voice recognition unit 510 is configured to recognize a word (for example, a word for instructing an image character set in advance such as 'dance' or 'wink' to perform a specified operation from the voice data). The operation controller 540 selects an additional character set composed of image characters corresponding to each word from the character sets stored in the storage unit 410, and recognizes the image character constituting the additional character set. The video character corresponding to the word is read and output.
