<p>The present invention relates generally to control of motor vehicles with the use of security systems and, more specifically, to protection of various objects, for example, motor vehicles against an unauthorized access of unauthorized persons to security systems. Subject matter of the invention. A system for controlling motor vehicles to provide protection against an unauthorized access based on automatic voice analysis comprising a text-independent parameter discrimination unit extracting spectral-and-time vocal parameters specific to the user's voice and manner of speech, and a text-dependent parameter discrimination unit for user verification and control purposes, which unit selects a set of parameters substantially sufficient for reliable recognition of a spoken word or sentence. The discrimination units have their inputs communicated to a microphone and connected to a user's identity verification subsystem and a service password and control command recognition subsystem. Such subsystems generate the signals for an adaptive control unit which is interfaced with a logical function memory, ignition key used to initialize the system, and vehicle subsystems. According to a method accomplished with the aid of such system, said system after being trained by the user to recognize his (her) voice, even if the voice is changed, say, due to a decease, acts on the appropriate vehicle information subsystems in the event of attempts of an unauthorized access to the vehicle and provides for the accomplishment of other procedures, including the "Retraining," "Valet," and "Car-jacking" modes. <IMAGE></p> |
