1. A method for enrolling with a resource security system, comprising:
- providing an access code to a system user;
accessing the resource security system using the access code;
prompting the user to input a voice biometric feature which identifies the user;
capturing voice biometric feature data associated with the user;
inducing variations in the voice biometric feature data associated with the user by synthetically generating additional utterances, including artificially modifying one or more parameters of the voice biometric feature data, wherein the parameters are selected from pitch, speaking rate, or amount of reverberation;
and associating the captured voice biometric feature data and the variations of the biometric feature data with the identity of the user for subsequent verification.

Abstract
An improved method is provided for enrolling with a resource security system. The method includes: providing an access code to a system user; accessing the resource security system using the access code; prompting the user to input a biometric feature which identifies the user; capturing a biometric feature associated with the user; and associating the captured biometric feature with the identity of the user for subsequent verification. The method further includes subsequently granting access to the secured resource based on biometric feature data input by the user.

16. A resource security system, comprising:
-
a user interface adapted to receive an access code from a user; an enrollment manager adapted to receive the access code and operable, in response to receiving the access code, to prompt the user to input a voice biometric feature which identifies the user; and biometric input devices, including a voice biometric input device operable to capture voice biometric feature from the user, the enrollment manager being further adapted to receive the voice biometric feature data from the biometric input device and operable to induce variations in the voice biometric feature data by synthetically generating additional utterances, including artificially modifying one or more parameters of the voice biometric feature data, wherein the parameters are selected from pitch, speaking rate, or amount of reverberation and associate the voice biometric feature data and the variations in the voice biometric feature data with the user. - View Dependent Claims (17, 18, 19, 20)

21. A method for administering user access to a secure resource based on biometric features associated with the system user, comprising:
-
enrolling a primary user with a resource security system, the resource security system being operable to control access to the secure resource; subsequently granting the primary user access to administrative functions of the resource security system based on a biometric feature associated with the primary user; employing the administrative functions to enroll a secondary user with the resource security system, including recording a voice biometric feature and inducing variations in the voice biometric feature by synthetically generating additional utterances, including artificially modifying one or more parameters of the voice biometric feature data, wherein the parameters are selected from pitch, speaking rate, or amount of reverberation; granting the secondary user access to a secured resource, including; (a) initially employing the voice biometric feature when making an initial attempt to verify identity of the secondary user; (b) in response to success of the initial attempt, granting the secondary user access to the secured resource; (c) in response to failure of the initial attempt, subsequently employing the variations in the biometric feature when making a subsequent attempt to verify identity of the secondary user; and (d) in response to success of the subsequent attempt, granting the secondary user access to the secured resource based on the variations in the biometric feature. - View Dependent Claims (22, 23, 24, 25)
