Title: Automatic locking method using voice recognition of portable telephone
Inventor: CHO YEONG HUN
IPC: H04B1/46
Filed: 2000-12-23
Abstract: PURPOSE: A method for automatically locking a portable phone using voice recognition is provided to previously input and store a user's voice signal, to request the user to input a voice signal at a preset time, to compare the stored voice signal with the inputted voice signal, and to permit the user to use the portable phone if matched. CONSTITUTION: If a user pushes a preset key to set up an automatic locking function(S1), the control part of his/her portable phone sets the present mode into a voice signal storage mode and displays a message to request the user to input a voice signal for a desired phrase(S2). If the user selects a desired phrase and inputs a voice signal for the selected phrase, the control part converts the voice signal into digital data and stores the converted data with the selected phrase(S3). Then the control part makes the user select a locking function operation time and stores the selected time(S4). The control part confirms periodically whether the present time reaches the preset locking function operation time(S5). In case that the present time reaches the preset locking function operation time, the control part displays the selected phrase(S6). At this moment, the control displays a message to request the user to input a voice signal for the displayed phrase(S7). If the user inputs a voice signal, the control part compares the inputted voice signal with the previously stored voice signal(S8). If the two signals are matched(S9), the control part allows the use of the portable phone(S10). However, if it is judged that the inputted signal is not identical to the previously stored voice signal, the control part executes the locking function so that the use of the portable phone can be prohibited(S11).
