The present invention relates to a method for automatically adjusting the volume using speech recognition and a mobile communication terminal using the same. More specifically, by recognizing the voice of the user and the other party and recognizing the specific setting, the method automatically adjusts the gain of the speaker and the microphone of the mobile communication terminal and automatically adjusts the volume using the voice recognition, and the mobile communication using the same. It relates to a terminal.

Since the Internet communication service, which is symbolized by the World Wide Web, has been in the spotlight, communication service has already made a big difference in human life in all aspects of society, economy and politics. It is hard to imagine life without the Internet, and the Internet is a part of life. Therefore, in recent years, the spread of high-speed communication networks has been greatly increased in order to use various communication services in a better environment.

Recently, mobile communication terminals have become one of the essential necessities of life that are indispensable for everyday life, and it is common to always carry them with you anytime, anywhere. In accordance with this trend, as a mobile communication terminal is required to perform various functions, the mobile communication terminal has developed into a trend of integration and multifunctionalization including an Internet access function, an MP3 function, and a camera function in the mobile communication terminal.

In addition, as the mobile communication terminal changes from a simple voice call means to use various additional services, there is a demand for a mobile communication terminal suitable for using additional services such as watching video on demand or watching TV.

Recently, with the development of wireless data transmission / reception technology of mobile communication terminals, the film, drama, video advertisement service, video mail service, and multimedia education service of VOD (Video On Demand) method are used not only for voice calls but also for transmitting and receiving existing text data such as short messages. It is possible to convert and transmit digital video data and digital audio data by using MPEG method which compresses-encodes moving image and audio signals so that the video and audio signals can be provided. Mobile communication terminals have been introduced with a multimedia playback function that can reproduce them as moving pictures and voice signals.

MP3 or MIDI playback that enables playback of digital audio data converted and transmitted as audio signals using the MPEG layer 3: MP3 or MIDI (Musical Instrument Digital Interface) methods that compress and encode audio signals. Mobile communication terminals with added functions are being introduced.

As the spread and use of mobile communication terminals increase, mobile communication terminals are used in various places. When making a call using a mobile communication terminal, the output sound may not be heard well in places with high external noise, such as a performance hall or a market. Therefore, the volume of the reception should be increased. Receive volume should be reduced to avoid interference.

1 is an explanatory diagram for explaining a volume control state of a conventional mobile communication terminal.

Codec units 102 and 122 for processing a voice signal input and output through the handsets 100 and 120 and voice signals input and output through the codec units 102 and 122 are processed through RF signals and transmitted to other communication equipment, or The mobile station modem (106, 126) and the MSM (106, 126) for processing the communication signal input from the outside through the antenna (104, 124) as a baseband signal of the handset (100, 120) Volume control buttons 108, 128 for adjusting the volume of the call.

Here, the handsets 100 and 120 may be installed by dividing into a microphone and a speaker on the mobile communication terminals 110 and 130.

Meanwhile, referring to the operation of a conventional mobile communication terminal, first, when a telephone number is transmitted through a base station (not shown) and a call is formed, a sender or a receiver transmits necessary voice through a handset of his mobile communication terminal. Or, the voice of the recipient is input to the codec unit 102 of the mobile communication terminal 100. Then, the codec unit 122 converts a voice signal of the user input through the handset 100 into a voice signal processing, for example, an analog voice signal into a digital signal and inputs it to the MSM unit 106. The MSM unit 106 modulates the digital voice signal input from the codec unit 102 and then processes the RF signal and transmits the RF signal to the MSM unit 126 of the counterpart mobile communication terminal 130 through the antenna 104.

Then, the MSM unit 126 of the counterpart mobile communication terminal 130 processes RF and demodulation signals of the counterpart mobile communication terminal 130 input through the antenna 124 and inputs them to the codec unit 122. The codec unit 122 converts the input digital voice signal into an analog signal and emits it to the outside through the handset 120.

Therefore, the voice call is executed between the mobile communication terminals 100 and 120 formed by the call through the above process, and if the volume of the sign language coming through the handset 120 of the mobile communication terminal 130 is small, the other party's caller Ask the user to raise his / her voice or press the volume control button 128 of his mobile communication terminal 130 up or down. For example, when the volume control button 128 is pressed during the call process, the MSM unit 126 recognizes this and adjusts the audio output amplification rate of the codec unit 122. In this case, the user adjusts the volume control button 128 as described above. As you keep moving up or down, you'll control yourself to hear the best volume. Here, the MSM unit 126 may store necessary data in the memory unit 132.

However, the conventional method for adjusting the sign language volume of the mobile communication terminal has a problem of causing inconvenience to the user because it is a method of manually adjusting the sign language volume of the mobile communication terminal.

In order to solve the above-described problems, the present invention, by recognizing the voice of the user and the other party and recognizes a specific set, automatically adjusts the gain of the speaker and microphone of the mobile communication terminal and automatically adjusts the volume using voice recognition It is an object of the present invention to provide a method and a mobile communication terminal using the same.

3 is a flowchart illustrating a method of adjusting a volume using voice recognition according to a preferred embodiment of the present invention.

The mobile communication terminal 200 registers voice recognition (S310). The counterpart mobile communication terminal is registered so that the mobile communication terminal 200 uses voice recognition through the mobile communication network.

The voice recognition unit 201 of the mobile communication terminal 200 registers a comment recognized (S320). For example, "sound is loud", "sound is low", "speak loudly." And "talk quietly." When the user of the mobile communication terminal 200 is input through the microphone 270, the voice recognition unit 201 stores the comment. And the user sets the action for each comment.

The mobile communication terminal 200 and the counterpart mobile communication terminal connect a call through a wireless access network (not shown) and a mobile communication switching center (not shown), and perform a voice call (S330).

The voice recognition unit 201 recognizes the voice of the user of the mobile communication terminal 200 and the voice of the user of the counterpart mobile communication terminal (S340).
