A system and method enrolls a speaker with an enrollment utterance and authenticates a user with a biometric analysis of an authentication utterance, without the need for a PIN (Personal Identification Number). During authentication, the system uses the same authentication utterance to identify who a speaker claims to be with speaker recognition, and verify whether is the speaker is actually the claimed person. Thus, it is not necessary for the speaker to identify biometric data using a PIN. The biometric analysis includes a neural tree network to determine unique aspects of the authentication utterances for comparison to the enrollment authentication. The biometric analysis leverages a statistical analysis using Hidden Markov Models to before authorizing the speaker.

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.

Methods and apparatus for activating telephone services in response to speech are described. A directory including names is maintained for each customer. A speaker dependent speech template and a telephone number for each name, is maintained as part of each customer's directory. Speaker independent speech templates are used for recognizing commands. The present invention has the advantage of permitting a customer to place a call by speaking a person's name which serves as a destination identifier without having to speak an additional command or steering word to place the call. This is achieved by treating the receipt of a spoken name in the absence of a command as an implicit command to place a call. Explicit speaker independent commands are used to invoke features or services other than call placement. Speaker independent and speaker dependent speech recognition are performed on a customer's speech in parallel. An arbiter is used to decide which function or service should be performed when an apparent conflict arises as a result of both the speaker dependent and speaker independent speech recognition step outputs. Stochastic grammars, word spotting and/or out-of-vocabulary rejection are used as part of the speech recognition process to provide a user friendly interface which permits the use of spontaneous speech. Voice verification is performed on a selective basis where security is of concern.
