ABSTRACT:
A vehicle theft prevention/security system having a concealed module capable of learning, and then recognizing the voice of the owner or authorized operator. The module controls (switches) the operation of a concealed relay that normally interrupts current to the starter solenoid or ignition system unless the owner or authorized operator speaks into a conveniently mounted microphone within the vehicle. The module may be programmed to recognize the voice of the owner or authorized user, regardless of the spoken word(s), or the module may be programmed to recognize only a certain password spoken only by a certain owner or authorized user. Once the module recognizes the owner or authorized user, the relay then switches to provide current to the previously interrupted ignition system or starter solenoid. The module provides audio output/feedback to the owner or authorized user during operation.
