<p>PURPOSE:To prevent illegal use with the sound-recorded voice of a 3rd party by generating a random number at each speaker recognition request, and outputting a word name corresponding to the random number and giving a generation menu. CONSTITUTION:When a speaker's code is inputted, a random number generating circuit 40 outputs an optional number of random numbers in optional order and sends them to a word dictionary 18. The dictionary 18 uses the respective random numbers as address signals to output word names which are stored previously in order to an input indication part 20 and a standard pattern memory 22. A display part 20 displays the generation menu corresponding to the word names. A speaker voice a word of a required number of times to a speech input part 24 according to the generation menu. Consequently, a recognition processing part 26 collates feature parameters obtained by analyzing the voice with standard patterns stored on the standard pattern memory 22. Therefore, the illegal use by the 3rd party by the sound-recorded voice is prevented.</p> |
