Speech activated security systems and methods
First Claim
1. A speech activated device comprising:
- display means for visually displaying to a user of said device a plurality of code symbols, each in one of a plurality of spatial positions in a predetermined spatial pattern of code symbol positions, each of said code symbols having a predetermined pronunciation;
means coupled to said display means for causing the display of said plurality of code symbols and for varying the position of at least some code symbols in the spatial pattern of code symbols;
microphone means for generating microphone signals in response to a plurality of speech input commands that correlate to spatial code symbol positions of a sequence of code symbols;
means for converting said microphone signals generated from said spoken spatial code symbol positions to code symbols and comparing said symbols to a valid code for a user of the device, and for providing an output signal in response thereto.

Abstract
Speech actuated security devices and methods whereby a lock, or other security or access device, may be actuated by a speech input thereto, but without disclosure of the actual code where doing so to those hearing the code words spoken during use of the security device. The security device includes a microphone, a display for displaying a plurality of code elements, and a processor for controlling the display and analyzing the microphone signal to detect a proper sequence of code elements spoken by a user as detected by the microphone and to operate the security device in response thereto. The code elements are displayed on the display under processor control in various patterns. With the proper sequence of code elements for operation of the security device not being a preset sequence of code elements, but rather being the code elements which appear in each of a proper sequence of spatial code element positions in the pattern of code elements being displayed by making the code elements displayed in the pattern viewable only by the user during use of the security device. Hearing the code elements being spoken by the user conveys no information about the actual code as a spoken sequence which will operate the security device at any one time and will change for the next operation of the security device by the reassignment of the code elements to new spatial positions within the pattern of code elements in the display. Various embodiments and methods of operation thereof are disclosed.

24. A method of operating a device comprising the steps of:
-
(a) providing a display that has plurality of spatial code symbol positions; (b) displaying a plurality of code symbols in the display, the spatial code symbol position of each code symbol within the display being varied from time to time; (c) sensing a series of speech input command that correlate to the spatial code symbol positions of a sequence of code symbols; (d) converting the spoken spatial code symbol positions into code symbols; and
,(e) comparing said code symbols with a valid code and, providing an output signal. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
