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.

Abstract: A security method compares a present verbal utterance with a previously recorded verbal utterance by comparing time-frequency domain representations of the utterances, with multiple repeat utterances forming a basis for determining a variation in repetitious performance by an individual, and similar differences between enrollment and challenge utterances forming a basis for a similar analysis of variance between enrollment and challenge utterances. In one embodiment a set of enrollment data is searched by each challenge until either a match is made, indicating an action, possibly dependent upon the specific match, or no match is made indicating an abort. In one application an individual is accepted or rejected as an imposter, in another applicaton, a selected action is accepted as corresponding to a verbal command.
