Data transmission method using internet network {METHOD FOR TRANSFERING DATA THROUGH INTERNET}

The present invention relates to a data transmission method using the Internet network, and more particularly, to a data transmission method using the Internet network to reduce the amount of data transmitted from the Internet network to facilitate data processing without congestion.

Transmission technology is a technology used to send and receive information converted into an electrical signal with a counterpart. The transmission technology is classified into a subscriber transmission connecting a subscriber and a communication device and an inter-station transmission connecting an exchange period.

Transmission technology includes pulse code modulation (PCM) technology that converts analog signals, such as voice, into digital signals that are easy to handle in transmission systems, multiplexing technology that allows you to configure communications networks economically, and optical communications that can handle a lot of information at once. It covers all the technologies used for communication, including technology, and is one of the three elements that make up a communication network with terminals and exchanges.

Hereinafter, a voice data transmission apparatus and a transmission method using a conventional internet network will be described with reference to the accompanying drawings.

1 is a block diagram of a voice data transmission apparatus using a conventional internet network.

As shown in FIG. 1, a block structure of a data transmission apparatus using a conventional Internet network includes a first general telephone 1 for inputting and outputting analog voice data and an analog voice data input and output through the first general telephone 1; A first guide system 2 for converting to digital data, a first voice compression and decompression unit 3 for compressing digital data digitally converted by the first guide system 2, and the first voice compression and reconstruction An internet network 9 for transmitting the compressed digital data of the unit 3 to another region, and a second voice compression and restoration unit 6 for receiving and restoring the digital compressed data transmitted through the internet network 9. And a second guide system (7) for converting the restored digital data into analog voice data, and a second general telephone (8) for outputting analog voice data of the second guide system (7). It is.

At this time, the Internet network 9 is composed of first and second Internet access server (4) (5) for connecting the signal generated from the first general telephone (1) to the second general telephone (8), The first and second guidance systems 2 and 7 are constituted by answering machines.

In this case, the answering machine will be described briefly. The voice information is transmitted to or received from a user through a mailbox, or a signal desired by a user of a voice and other telephone networks by interworking a telephone network with a computer network. It is a new complex information service system that converts the data into a form and provides it quickly. Even when using the Internet, data is transmitted or received through an answering device.

A voice data transmission method using a conventional internet network having the configuration as described above will be described.

First, when an outgoing call processor inputs a voice signal through the first general telephone 1, the first guide system 2 determines whether to communicate using the Internet network. When voice data is input, analog voice data is input. Digital conversion.

At this time, when converting analog voice data into digital voice data, ADPCM (Adaptive Differential Pulse Code Modulation) is used. The basic principle of the ADPCM is to predict the magnitude of the next input signal from the sample value of the voice signal input in the past and to quantize and transmit only the error signal that is different from the actual input signal. It is a method of obtaining an accurate input value by adding an error signal.

Then, the digitally converted speech signal is compressed by the first speech compression and decompression unit 3. That is, the analog voice data is converted into digital voice data having a transmission rate of 32 Kbps in the first guide system 2, and the 32 Kbps digital voice data as described above is converted into 5.3 to 6.3 by the first compression and decompression unit 3. Compress at about Kbps.

Reducing such transmission speed is to provide multiple call paths in addition to reducing transmission cost and information accumulation cost.

Then, the compressed digital voice data is transmitted to the internet network 9.

At this time, the Internet network 9 receives the compressed digital voice data and transmits it to another area. The second Internet server 5 of the called party is transmitted through the first Internet server 4 on the side of the call processing. Will be sent).

Next, the second Internet server 5 restores the compressed digital voice data through the second voice compression and decompression unit 6.

Then, the restored digital voice data is transmitted to the second general telephone 8 of the incoming call processor through the second guide system 7, where the digital voice data is analog-converted and transmitted to the incoming call processor.

The conventional voice data transmission apparatus and transmission method using the Internet has the following problems.

In other words, the amount of compressed voice data is also about 1/10 of that of the first digitally converted voice data. Therefore, the amount of compressed data is not very large. This stagnant phenomenon occurred.

The present invention has been made to solve the problems of the voice data transmission method using the Internet network as described above by using a voice recognizer and TTS by reducing the amount of data transmission using the Internet network to prevent congestion of the Internet network. It is an object of the present invention to provide a voice data transmission method.

In the voice data transmission method using the Internet network of the present invention for achieving the above object, the step of converting the voice data into text data, the step of connecting the text data to the called party by connecting to the Internet network, the transmitted text data Converting to speech.

In this case, a voice recognizer is used to convert the digitally converted voice data into text, and a text to speech (TTS) device is used to convert the text data into voice.

A data transmission method using an internet network according to the present invention will be described with reference to the accompanying drawings.

2 is a block diagram illustrating a data transmission apparatus using the Internet network of the present invention.

As shown in FIG. 2, the data transmission apparatus using the Internet network of the present invention uses a first voice input / output unit 11 for inputting and outputting analog voice and an analog voice data input and output through the first voice input / output unit 11. A first guide system 12 for converting the voice data, a first voice recognition unit 13 for converting the data digitally converted by the first guide system 12 into text, and the data converted into text An Internet network 21 for receiving and transmitting to another area, a second TTS (Text To Speech) 16 for converting text data transmitted through the Internet network 21 into digital voice data, and converting to the digital voice And a second guide system 17 for analog-to-speech the converted data to the second voice input / output unit 18.

At this time, the Internet network 21 is composed of first and second Internet access server 14, 15 for connecting the signal generated from the first voice input and output unit 11 to the second voice input and output unit 18, The first and second guidance systems 12, 17 comprise an answering machine.

The first TTS 20, which has not been described above, is used when the originating call processing side receives voice data transmitted from the called party.

The first and second voice input / output units 11 and 18 are constituted by a microphone, a wired / wireless telephone or a mobile terminal.

In the voice data transmission method using the Internet network of the present invention having the above-described configuration, first, when an originating call processor inputs an analog voice signal through the first voice input / output unit 11, the first guide system 12 transmits the Internet network. Determining (selection) whether or not to communicate with a user and inputting audio data causes digital conversion of analog voice data.

In this case, when converting analog voice data into digital voice data, an adaptive differential pulse code modulation (ADPCM) or a pulse code modulation (PCM), which is a method of predictive encoding, is used.

In this case, a voice recognizer is used to convert the digitally converted voice data into text data, and a text to speech (TTS) device is used to convert the text data into voice.

In other words, text is similar to ASCII (American National Standard Code for Information Interchange) code or KS standard completion Korean code.

Such speech recognition is strictly speaking a syllable unit rather than a letter.

In this case, the ASCII code as described above is composed of 7 bits (8 bits including parity bits). When Hangul is also divided into units of syllables pronounced as initial, neutral and final, each bit is divided into 16 units for one syllable. Text data in the case of allocating the bit 2 ⁴ can transmit the first analog voice data at about 100 to 400 bps.

Subsequently, when the text data as described above is connected to the Internet network 21, the text data is transmitted from the first Internet access server 14 on the outgoing call side to the second Internet access server 15 on the called side. .

Next, when the second Internet access server 15 on the called side transmits the text data to the second TTS (Text To Speech) 16 installed on the called side, the second TTS 16 converts the text data into digital. The digital voice data is restored to the voice data, and the recovered digital voice data is transmitted to the incoming call processor through the second voice input / output unit 18 as analog voice data in the second guide system 17.

In the data transmission method using the Internet network according to the present invention, since the voice data is textualized in a telephone connection using the Internet network, the amount of data can be reduced to about 1/100, so even when the number of users using the Internet network increases or the amount of data is congested, It is possible to transmit data without network congestion.
