1. A method comprising:
- receiving an audible command from a user;
automatically processing at least portions of the audible command with respect to previously developed identification information to correlate the user with a likely identity;
automatically responding to the audible command in a predetermined way as a function, at least in part, of the likely identity, wherein the function of likely identity includes a confidence level that the user has been correctly correlated with the likely identity, and the confidence level is compared against a respective one of a plurality of predefined threshold levels respectively corresponding to each of a plurality of different audible commands.

Abstract
An audible command can be utilized to both permit identification of the speaker and to permit subsequent actions that comprise a corresponding response to the audible command when the identity of the speaker correlates with that of a previously authorized individual. Such identification can be supplemented with other identification mechanisms. Hierarchical levels of permission can be utilized, with or without confidence level thresholds, to further protect the device against unauthorized access and/or manipulation.

13. A method for use with a controllable platform, comprising:
-
providing a plurality of user-controllable parameters; associating each of at least some of the plurality of user-controllable parameters with at least one corresponding audible command; providing identification information that correlates at least one audible parameter with a particular user and associating that particular user with a given permission status; receiving an audible command from a user; automatically processing at least portions of the audible command with respect to the identification information to determine whether the user likely comprises the particular user; when the user likely comprises the particular user, based at least in part on a confidence level that the user is the particular user, and that the confidence level exceeds a corresponding one of a plurality of thresholds associated with the audible command, automatically responding to the audible command in a predetermined way as a function, at least in part, of the given permission status. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. An apparatus comprising:
-
at least one user controllable interface having a predetermined audible command associated therewith; a speech transducer; at least one item of identification information that correlates at least one audible parameter with a particular user; permission status information that is correlated with the particular user; a speech recognition engine having an input operably coupled to the speech transducer and having a recognized audible command output operably coupled to the at least one user controllable interface; a user identifier having an input operably coupled to the speech transducer and being operably responsive to the at least one item of identification information, and having a permission output operably coupled to at least one of the speech recognition engine and the at least one user controllable interface, wherein the user identifier comprises identification means for extracting at least one item of characterizing biometric information from an audible command as received via the speech transducer and for comparing at least portions of the at least one item of characterizing biometric information with the at least one item of identifying information to determine at least a likelihood relative to a plurality of threshold levels that the audible command was uttered by the particular user; such that the user identifier can identify a source of an audible command as being the particular user and respond by permitting the audible command to control the at least one user controllable interface. - View Dependent Claims (21, 22, 23, 24)
