A system for verifying and enabling user access, which includes a voice registration unit for providing a substantially unique and initial identification of each of a plurality of the speaker / users by finding the speaker / user's voice parameters in a voice registration sample and storing same in a database. The system also includes a voice authenticating unit for substantially absolute verification of an identity of one of said plurality of users. The voice authenticating unit includes a recognition unit for providing a voice authentication sample, and being operative with the database. The voice authenticating unit also includes a decision unit operative with the recognition unit and the database to decide whether the user is the same as the person of the same identity registered with the system, such that the identity of one of the plurality of users is substantially absolutely verified.

A text-dependent voice authentication system that performs authentication by urging a user to input a keyword by voice includes: an input part (11) that receives a voice input of a keyword divided into a plurality of portions with an utterable unit being a minimum unit over a plurality of times at a time interval for each of the portions; registered speaker-specific syllable model DB (20) that previously stores a registered keyword of a user as a speaker model created in the utterable unit; a feature value conversion part (12) that obtains a feature value of a voice contained in a portion of the keyword received by each voice input in the input part (11) from the portion; a similarity calculation part (13) that obtains a similarity between the feature value and the speaker model; a keyword checking part (17) that determines whether or not voice inputs of all the syllables or phonemes configuring an entire registered keyword by the plurality of times of voice inputs, based on the similarity obtained in the similarity calculation part; and an authentication determination part (19) that determines whether to accept or reject authentication, based on a determination result in the keyword checking part and the similarity obtained in the similarity calculation part.

A system and method of providing voice authentication to institutional customers having consumers or users. The system includes an enrollment module, a verification module, and a database. Each institutional customer has an authentication profile on the system that includes both i) instructions indicating which one or more of the voice biometric engines are to be used for a given consumer's enrollment and / or authentication, and ii) variables for implementing those instructions. A given institutional customer may have more than one set of instructions or variables for different classes of users. Vocal information is received from a user, and a baseline voiceprint is constructed therefrom for enrollment. Subsequently, more vocal information is received from the user to construct a temporary voiceprint. The temporary voiceprint is compared to a corresponding baseline voiceprint in accordance with the institutional customer's authentication profile. The profile is preferably remotely configurable by the institutional customer.

A system is disclosed for enabling communication between server resources and a wide spectrum of end-terminals to enable users access to the resources of both converged and non-converged networks via voice and / or electronically generated commands. An electronic personal assistant (ePA) incorporates generalizing / abstracting communications channels, data and resources provided through a converged computer / telephony system interface such that the data and resources are readily accessed by a variety of interface formats including a voice interface or data interface. A set of applications provide dual interfaces for rendering services and data based upon the manner in which a user accesses the data. An electronic personal assistant in accordance with an embodiment of the invention provides voice / data access to web pages, email, file shares, etc.The electronic personal assistant enables a user to transmit voice commands to a voice-based resource server to provide information accessible to the resource server. In accordance with an aspect of an embodiment of the invention, a user is authenticated by receiving vocal responses by a user to one or more requests variably selected and issued by a speaker recognition-based authentication facility. Thereafter, an application proxy is created. The application proxy acts on behalf of the authenticated authorized user.In accordance with particular aspects of the specific embodiments of the invention, a set of remotely accessed voice applications are provided. One such application comprises a personal interactive multimedia response (IMR). Each user configures a personal IMR system. In a converged network environment, the user is provided access to the IMR through a personal computer interface, web interface, instant message, e-mail, as well as a voice user interface over a telephone connection.A configurable distributed conference bridge is another potential application incorporated within the converged network architecture model of the present invention. The distributed conference bridge enables local conference resources to be utilized and incorporates external service bureau conference bridge resources when needed to supplement the internal conference bridge resources of a system.

A voice authentication system includes: a standard template storage part 17 in which a standard template that is generated from a registered voice of an authorized user and featured with a voice characteristic of the registered voice is stored preliminarily in a state of being associated with a personal ID of the authorized user; an identifier input part 15 that allows a user who intends to be authenticated to input a personal ID; a voice input part 11 that allows the user to input a voice; a standard template / registered voice selection part 16 that selects a standard template and a registered voice corresponding to the inputted identifier; a determination part 14 that refers to the selected standard template and determines whether or not the inputted voice is a voice of the authorized user him / herself and whether or not presentation-use information is to be outputted by referring to a predetermined determination reference; a presentation-use information extraction part 19 that extracts information regarding the registered voice of the authorized user corresponding to the inputted identifier; and a presentation-use information output part 18 that presents the presentation-use information to the user in the case where it is determined by the determination part that the presentation-use information is to be outputted to the user.
