Biometric voice command and control switching device and method of use
First Claim
1. A biometric voice command and control switching device for operably controlling a controlled device in response to a currently spoken challenge utterance by correlating and comparing the currently spoken challenge utterance to at least one previously stored reference utterance, the biometric voice command and control switching device comprising:
- a microphone assembly for receiving the currently spoken challenge utterance and the at least one previously stored reference utterance;
a voice processing circuit for creating an electronic signal indicative of the currently spoken challenge utterance and the at least one previously stored reference utterance;
a memory for storing the electronic signals of the currently spoken challenge utterance and the at least one previously stored reference utterance;
a processor for comparing the electronic signals of the currently spoken challenge utterance and the at least one previously stored reference utterance and determining if there is a match;
an interface circuit for operably controlling the controlled device in response to the currently spoken challenge utterance when a match is determined by the processor; and
a housing containing the microphone assembly, the housing having an acoustic vent that enables the microphone assembly to receive sound, the acoustic vent having a weatherproof fabric cover covering the acoustic vent.

Abstract
A biometric voice command and control switching device has a microphone assembly for receiving a currently spoken challenge utterance and a reference utterance, and a voice processing circuit for creating electronic signals indicative thereof. The device further includes a memory for storing the electronic signals, and a processor for comparing the electronic signals to determine if there is a match. If there is a match, an interface circuit enables the operable control of the controlled device.

12. A method for controlling locks on a vehicle, the method comprising the steps of:
-
providing a biometric voice command and control switching device comprising; first and second microphone assemblies operably connected to a combiner; a housing containing the first microphone assembly, the housing having an acoustic vent that enables the first microphone assembly to receive sound, the acoustic vent having a weatherproof fabric cover covering the acoustic vent; a voice processing circuit operably connected with a memory and a processor; and an interface circuit operably connected with the processor; installing the first and second microphone assemblies on opposite sides of the vehicle, the first microphone assembly being positioned in a secured space of a door of the vehicle; operably connecting the combiner of the first and second microphone assemblies with the voice processing circuit; operably connecting the interface circuit with the locks of the vehicle; receiving a reference utterance via one of the first or second microphone assemblies; creating an electronic signal indicative of the reference utterance; storing the electronic signal of the reference utterance in the memory; receiving a currently spoken challenge utterance via one of the first or second microphone assemblies; reducing background noise received along with the currently spoken challenge utterance by reducing far-field sounds that are received; creating an electronic signal indicative of the currently spoken challenge utterance; storing the electronic signal of the currently spoken challenge utterance in the memory; correlating and comparing the electronic signals of the reference utterance and the currently spoken challenge utterance, utilizing the processor, and determining if there is a match; and generating a state signal to the locks of the vehicle to either lock or unlock the vehicle in response to the currently spoken challenge utterance, if there is a match. - View Dependent Claims (13)
