Abstract
A method executed by a voice decoding device includes the following steps: receiving and determining whether an identification data is correct; if the identification data is incorrect, showing a decoding array, including plural characters, wherein positions of the plural characters are randomly distributed; receiving a numerical voice command, wherein the numerical voice command includes plural arranged decoding characters in regular turn; determining whether the numerical voice command corresponds to a preset decoding trace; arranging the plural decoding characters corresponding to the decoding array to form an arranged trace; when the arranged trace is the same as the decoding trace, unlocking the voice decoding device. By randomly displaying the decoding array, the invention permits a user to speak the sequence corresponding to the preset decoding trace so that unauthorized users cannot decode the voice decoding device by eavesdropping the pin, so as to achieve the better anti-theft effect.
