  • Patent number: 5777571
    Abstract: A remove control device that has voice recognition and user ID restriction functions equipped with a receiver is provided. The device includes a radio frequency (RF) receiving circuit, a demodulator, a voice input control device, an analog to digital conversion signal control unit, a buffer, a memory, a voice recognition processing unit, an instruction verification device, and an output control device. When the receiver is in a voice training mode, the signal characteristics of the voice command from the user can be stored in a memory. When the receiver is in an instruction execution mode, the receiver receives signals transmitted from the emitter, recognizes and compares the signal with the original signal stored in the memory during the voice training mode and determine if it is from an authorized user. Only after the identification matches the instruction verification device that verifies the received instruction, the output control device outputs a corresponding control signal.
