이하, 상기와 같은 본 발명 음성인식을 이용한 이동통신 단말기의 잠금 장치 및 방법의 바람직한 실시예를 첨부한 도면에 의거 상세하게 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the locking device and method of the mobile communication terminal using the present invention as described above in detail as follows.

먼저, 본 발명의 바람직한 실시예를 설명하기에 앞서 본 발명의 전체적인 개념을 간략하게 설명하면 다음과 같다.First, the general concept of the present invention will be briefly described before explaining the preferred embodiment of the present invention.

본 발명은 이동통신 단말기의 음성인식을 이용한 전화걸기 기능을 이용한 것이다. 이동통신 단말기의 사용자가 음성을 미리 녹음해두고 녹음한 음성에 따른 전화번호를 설정해두면 사용자가 일일이 전화번호를 입력하지 않고도 전화기에 상기 녹음한 단어를 음성으로 단말기에 입력하면 단말기에서는 녹음된 음성과 단말기에 입력된 음성을 비교하여 동일한 음성에 설정되어 있는 전화번호를 발신하는것이다.The present invention utilizes a telephone dialing function using voice recognition of a mobile communication terminal. If the user of the mobile communication terminal has pre-recorded the voice and set the phone number according to the recorded voice, the user inputs the recorded word to the terminal by voice without inputting the telephone number. It compares the voice input to the terminal and sends out the phone number set to the same voice.

본 발명에서는 단말기의 잠금 기능을 구현함에 있어서 이러한 종래 기술의 음성인식 기능을 이용한 것이다. 즉, 단말기의 사용자는 단말기의 잠금 기능을 설정할 때 비밀번호를 입력하지 않고 자신의 음성을 입력함으로써 단말기 기능에 잠금 기능을 설정하는 것이다.In the present invention, the conventional voice recognition function is used in implementing the locking function of the terminal. That is, the user of the terminal sets the lock function to the terminal function by inputting his / her voice without inputting a password when setting the lock function of the terminal.

그러면, 단말기를 사용할 때 단말기에서는 비밀번호입력을 요구하는 것이 아니라 음성 입력을 비밀번호로써 요구하고, 입력된 음성과 미리 녹음된 사용자의 음성을 비교하여 주파수 특성이 일치하는 경우에만 상기 사용자의 음성으로 판단, 잠금을 해제하는 것이다.Then, when using the terminal, the terminal does not require a password input, but requires a voice input as a password, and compares the input voice with the pre-recorded user's voice and judges the user's voice only when the frequency characteristics match. To unlock it.

도 2는 본 발명에 따른 음성인식을 이용한 이동통신 단말기의 잠금 장치의 구성 블록도이다.2 is a block diagram illustrating a locking device of a mobile communication terminal using voice recognition according to the present invention.

도시된 바와 같이, 상기 안테나(10)로부터 무선 채널을 통하여 송수신 데이터를 처리하는 RF부(11)와, 상기 RF부(11)와 연결되어 상기 RF부의 제어에 의하여 정합기능을 수행하는 RF 인터페이스부(12)와, 상기 RF부(11)와 연결되어 아날로그 신호를 디지털 신호로 변환하는 기능을 수행하는 ADC부(14)와 상기 RF부(11)와 연결되어 RF부의 구성소자를 제어하는 SBI(Serial Bus Interface)부(16)와, 사용자에게 안내하는 음성안내 메시지와 사용자가 단말기의 잠금 기능을 위하여 미리 녹음한 음성을 저장하는 보이스롬(Voice ROM)(16)과, 단말기의 잠금 기능 제공을 위하여 상기 단말기에 입력된 음성과 상기 보이스롬(17)에 저장된 음성의 동일 여부를 판별하는 음성판별부(17)와, 사용자에게 안내메시지를 전달하는 스피커(20) 및 상기 사용자의 음성을 입력받는 마이크(21)로 구성되어 있다.As shown, an RF unit 11 for processing data transmitted and received from the antenna 10 through a wireless channel, and an RF interface unit connected to the RF unit 11 to perform a matching function under control of the RF unit. (12), an ADC unit 14 connected to the RF unit 11 to convert an analog signal into a digital signal, and an SBI connected to the RF unit 11 to control components of the RF unit ( Serial Bus Interface) unit 16, Voice ROM (16) for storing a voice prompt message to guide the user and the pre-recorded voice for the lock function of the terminal, and providing a lock function of the terminal In order to receive the voice input unit 17 and the voice discriminating unit 17 for determining whether the voice stored in the voice ROM 17 is the same, the speaker 20 for delivering a guide message to the user and the user's voice Consisting of a microphone 21 have.

상기와 같이 구성된 음성인식을 이용한 이동통신 단말기의 잠금 장치의 동작을 설명하면 다음과 같다.Referring to the operation of the locking device of the mobile communication terminal using the voice recognition configured as described above are as follows.

상기 사용자가 단말기의 잠금 기능을 설정하는 경우는 개인정보 보호, 발신제한, 또는 특정 기능을 사용제한 등의 이유가 있다. 이러한 경우 사용자는 본 발명에 의하여 단말기메뉴의 잠금 기능을 설정하게 되고, 이때 종래의 기술에서는 비밀 번호를 입력하게 되지만 본 발명에 의하여 비밀 번호 입력대신 사용자의 음성 암호를 입력하게 된다. 가령, 사용자가 "단말기"라는 음성암호를 입력하게 되면 그 음성은 단말기의 보이스롬에 저장된다.When the user sets the lock function of the terminal, there are reasons such as privacy protection, transmission restriction, or restriction on using a specific function. In this case, the user sets the lock function of the terminal menu according to the present invention. At this time, although the password is input in the related art, the user inputs the voice password instead of the password. For example, when a user enters a voice password of "terminal", the voice is stored in the voice ROM of the terminal.

그리고 나서, 단말기의 사용자 또는 타 사용자가 상기 음성암호가 입력된 단말기의 사용이나 발신을 시도하면 상기 단말기의 MSM(13)은 이를 감지하여 상기 보이스롬(16)에 저장되어 있는 음성안내 메시지를 송출, 음성암호 입력을 요구하게 된다.Then, when the user or another user of the terminal attempts to use or transmit the terminal in which the voice password is input, the MSM 13 of the terminal detects this and transmits a voice guidance message stored in the voice ROM 16. In this case, a voice password input is required.

상기 음성안내 메시지에 따라 음성 암호를 입력하면 상기 음성판별부(17)에서는 입력한 음성암호의 주파수 특성을 상기 보이스롬(16)에 저장된 음성암호와 비교하여 동일 음성 여부를 판단하여 그 결과를 상기 MSM(13)에게 전달한다. 이 음성판별은 입력한 단어의 동일성을 판별하는 것이 아니라 음성의 주파수특성을 판별하는 것이므로 동일한 단어를 입력하더라도 동일인이 아니면 음성암호는 거부된다.When the voice password is input according to the voice guidance message, the voice discriminator 17 compares the frequency characteristic of the input voice password with the voice password stored in the voice ROM 16 to determine whether the voice is the same, and the result is determined. To the MSM 13. This speech discrimination is not for discriminating the identity of the input words, but for discriminating the frequency characteristics of the speech. Therefore, even if the same words are entered, the speech password is rejected unless they are the same person.

상기 음성암호가 받아들여진 경우 MSM은 단말기 잠금을 해제하여 단말기의 사용 및 발신을 허용하고 음성암호가 거부된 경우, 즉 입력된 음성암호가 상기 보이스롬에 저장된 음성암호와 동일하지 않을 경우 MSM은 단말기 사용을 차단하게 된다.If the voice password is accepted, the MSM unlocks the terminal to allow the use and transmission of the terminal and if the voice password is rejected, that is, if the input voice password is not the same as the voice password stored in the voice ROM, the MSM It will block its use.

여기서, 음성암호가 일치하여 단말기 잠금이 풀린 경우 단말기의 사용이 종료된 후에는 자동으로 잠금 장치가 재설정된다. 단, 단말기의 잠금이 풀린 상태에서 단말기 잠금 메뉴를 해제하면 단말기 잠금 기능은 해제 모드로 전환된다.Here, when the terminal is unlocked because the voice passwords match, the lock is automatically reset after the use of the terminal is terminated. However, if the terminal lock menu is released while the terminal is unlocked, the terminal lock function is switched to the release mode.

도 3은 본 발명에 따른 음성인식을 이용한 이동통신 단말기의 잠금 방법을 보인 플로우챠트이다.3 is a flowchart illustrating a method of locking a mobile communication terminal using voice recognition according to the present invention.

상기 도 3에서 사용자는 단말기에 미리 음성암호를 입력하여 단말기를 잠금 상태로 설정해 놓았다고 가정한다. 단말기의 잠금 설정은 메뉴선택과 음성 입력으로 이루어지므로 본 발명에서는 설명을 생략한다.In FIG. 3, it is assumed that a user sets a terminal in a locked state by inputting a voice password to the terminal in advance. Since the lock setting of the terminal consists of menu selection and voice input, the description is omitted in the present invention.

먼저, 음성암호가 저장되어 단말기가 잠금 상태로 설정된 상태에서 사용자가 단말기의 사용을 시도한다(S11).First, in a state in which a voice password is stored and the terminal is set in a locked state, the user attempts to use the terminal (S11).

그러면, 단말기의 MSM은 이를 감지하여 단말기 내부의 보이스롬에 저장되어 있는 안내메시지를 송출하여 음성암호 입력을 요구한다(S13).Then, the MSM of the terminal detects this and transmits a guide message stored in the voice ROM inside the terminal to request a voice password input (S13).

사용자가 단말기에 음성암호를 입력하면 상기 입력한 음성암호를 단말기 내부의 보이스롬에 저장된 사용자의 음성암호와 비교하여 동일한 음성인지 여부를 판단한다(S15).When the user inputs the voice password into the terminal, the input voice password is compared with the voice password of the user stored in the voice ROM inside the terminal to determine whether the voice is the same (S15).

상기 판단결과, 단말기에 입력한 음성암호가 상기 보이스롬에 저장된 음성암호와 동일한 음성일 경우 잠금 설정을 해제하여 단말기 서비스를 제공한 후(S17), 상기 단말기의 사용이 종료되면 다시 잠금 상태로 전환한다(S19).As a result of the determination, if the voice password inputted to the terminal is the same voice as the voice password stored in the voice ROM, the lock setting is released and the terminal service is provided (S17). (S19).

상기 S15단계의 판단결과, 단말기에 입력한 음성암호가 상기 보이스롬에 저장된 음성암호와 동일하지 않은 음성일 경우, 상기 보이스롬(Voice ROM)에 저장된 안내메시지를 송출하여 음성암호 재입력을 요구하여(S21), 상기 재입력한 음성암호와 상기 보이스롬에 저장된 음성암호의 동일 여부를 다시 판단한다(S23).As a result of the determination in step S15, if the voice password inputted to the terminal is not the same as the voice password stored in the voice ROM, the voice message is sent to request the voice password re-entry by sending a guide message stored in the voice ROM. In operation S23, it is determined whether the re-entered voice code is identical to the voice code stored in the voice ROM (S23).

상기 S23단계의 판단결과, 상기 재입력한 음성암호와 상기 보이스롬에 저장된 음성암호가 동일할 경우, 잠금 설정을 해제하여 단말기 서비스를 제공한 후(S17), 상기 단말기의 사용이 종료되면 다시 잠금 상태로 전환하고(S19), 상기 재입력한 음성암호와 상기 보이스롬에 저장된 음성암호가 동일하지 않을 경우 단말기의 사용을 차단한다(S25).As a result of the determination in step S23, if the re-entered voice password and the voice password stored in the voice ROM are the same, the lock setting is released and the terminal service is released (S17). In step S19, if the re-entered voice password and the voice password stored in the voice ROM are not the same, use of the terminal is blocked (S25).
