Claim:
1. A mobile device having a function of controlling a call connection in a lock mode by using a voice signal, the mobile device comprising: a keypad which allows a user to input an execution command for setting a specific function or for performing a specific function; a controller which performs a corresponding operation in accordance with the execution command input to the keypad, a preset internal function, or an execution command applied from the outside; a microphone which allows the user to input a voice command under the control of the controller; a memory that stores at least one preset reference command under the control of the controller and stores the voice command input through the microphone under the control of the controller; an LED which represents an operation state of the mobile device under the control of the controller; a wireless transceiver which performs a voice call or a data communication between a transmitting terminal and a receiving mobile device; and a speaker which outputs a specific operation state or a user's voice signal under the control of the controller, wherein, when the receiving mobile device receives an incoming call from any transmitting terminal in a lock mode, the controller converts automatically the mobile device into a voice input mode for a predetermined period of time, and when it is determined that a specific voice command input by the user of the receiving mobile device in the voice input mode is successfully recognized by the receiving mobile device, the controller controls the wireless transceiver to control a call connection between the transmitting terminal and the receiving mobile device, wherein the controller determines whether the recognition process is successful or not according to whether or not there exist a command obtained by converting the voice command input by the user into a text data and a command registered previously in the memory in text or similar data, and wherein the controller determines whether or not there exists a reference text data which is the same as the converted text data, and wherein, based on the determination result, if there exists the reference text data, the controller determines that the recognition process is successful, and if there exists no reference text data, the controller determines whether or not there exists the similar text data by using a similarity comparison.
