<p>PURPOSE:To improve safety and operability by receiving the voice signal transmitted from a controller by radio, identifying the personal feature of the voice, and outputting locking/unlocking signals. CONSTITUTION:A portable controller outputting the voice inputted from a microphone as a radio signal is provided. A door lock control device constituted of a double super-heterodyne type voice reception section 20 and a voice recognition section 40 is provided on the reception side. Next, in the case of voice registration, the voice signal transmitted from the controller is inputted to the recognition section 40, and its feature is extracted by a voice feature extracting circuit 43 and stored in a standard pattern memory 47. When locking or unlocking, the circuit 43 receives the voice signal and outputs its feature to a pattern matching circuit 44. Further, the circuit 44 compares this signal with the record of the memory 47 and outputs a similarity signal to a judging circuit 45. Moreover, the circuit 45 compares this signal with the threshold value and judges the propriety of locking or unlocking. Locking/unlocking signals can be inputted in person, and high safety can be secured.</p> |
