CA 2509545

The present invention relates to methods and systems for enrolling a user for voice authentication and for performing voice authentication on a user of a network. The method of enrolling a user for voice authentication includes verifying the identity of the user and assigning an enrolment identifier to the user, if the identity of the user is verified. The enrolment identifier is then presented to the user. Subsequently, the user is prompted to utter a personal voice authentication password. The personal password uttered by the user is received and stored. A voice print model for the user is generated from the previously stored voice print. The method further includes storing the voice print model and associating the voice print model and the personal password with the enrolment identifier assigned to the user to facilitate retrieval thereof during voice authentication of the user. A method for performing voice authentication on a user of a network is also provided. The method includes determining whether the user is enrolled for voice authentication based on an available attribute of the logical address of the user on the network. Upon determining that the user is enrolled for voice authentication, a personal password and stored voice print model for the user is retrieved. The stored voice print model includes a voice print of a personal password previously uttered by the user. The method further includes prompting the user to utter the personal password and receiving a spoken response from the user. The spoken response is verified to determine whether it contains the personal password and whether it matches the stored voice print model. If the spoken response contains the personal password and matches the stored voice print model for the user, the identity of the user is authenticated.
