Disclosed herein are systems, methods, and non-transitory computer-readable storage media for performing speaker verification. A system configured to practice the method receives a request to verify a speaker, generates a text challenge that is unique to the request, and, in response to the request, prompts the speaker to utter the text challenge. Then the system records a dynamic image feature of the speaker as the speaker utters the text challenge, and performs speaker verification based on the dynamic image feature and the text challenge. Recording the dynamic image feature of the speaker can include recording video of the speaker while speaking the text challenge. The dynamic feature can include a movement pattern of head, lips, mouth, eyes, and/or eyebrows of the speaker. The dynamic image feature can relate to phonetic content of the speaker speaking the challenge, speech prosody, and the speaker's facial expression responding to content of the challenge.

Disclosed herein are systems, methods, and non-transitory computer-readable storage media relating to speaker verification. In one aspect, a system receives a first user identity from a second user, and, based on the identity, accesses voice characteristics. The system randomly generates a challenge sentence according to a rule and/or grammar, based on the voice characteristics, and prompts the second user to speak the challenge sentence. The system verifies that the second user is the first user if the spoken challenge sentence matches the voice characteristics. In an enrollment aspect, the system constructs an enrollment phrase that covers a minimum threshold of unique speech sounds based on speaker-distinctive phonemes, phoneme clusters, and prosody. Then user utters the enrollment phrase and extracts voice characteristics for the user from the uttered enrollment phrase. The system generates a user profile, based on the voice characteristics, for generating random challenge sentences according to a grammar.

A method and apparatus for using a classifier for processing a query are disclosed. For example, the method receives a query from a user, and processes the query to locate one or more documents in accordance with a search engine having a discriminative classifier, wherein the discriminative classifier is trained with a plurality of artificial query examples. The method then presents a result of the processing to the user.

A pre-registration procedure is utilized to create a user profile for a user of a multi-factor authentication ('MFA') service. A client application installation procedure is utilized to install a client application on a computing device that is to be utilized as an authentication factor for the MFA service. A computing device enrollment procedure is utilized to enroll the computing device on which the client application was installed for the MFA service. A voice enrollment procedure is utilized to create a voice print for the user of the computing device that is to be utilized as an authentication factor for the MFA service. An authentication procedure is utilized to provide multi-factor authenticated access to a service, such as an online service that provides access to sensitive account information.

Authentication techniques utilizing a computing device

The present disclosure relates to verifying transactions using user devices. A client device used to complete a transaction with a server computer. The client device communicates with a user device such as a smart phone, laptop computer, or other computing device. The user device communicates with the client device and a verification server via the out-of-band communication channel. The verification server receives two or more copies of session data associated with the transaction occurring between the client device and the server computer. One copy of the session data is received from the server computer and another copy of the session data is provided by the user device. The two copies of the session data are compared by the verification server or by the user device, and mismatches are reported as suspected malicious software attacks.

Systems and methods for creating and using geo-centric language models are provided herein. An exemplary method includes assigning each of a plurality of listings to a local service area, determining a geographic center for the local service area, computing a listing density for the local service area, and selecting a desired number of listings for a geo-centric listing set. The geo-centric listing set includes a subset of the plurality of listings. The exemplary method further includes dividing the local service area into regions based upon the listing density and the number of listings in the geo-centric listing set, and building a language model for the geo-centric listing set.

An interactive voice response (IVR) system which allows a caller to barge-in on all prompts, yet still allows the caller to receive important information contained in the prompts. When a caller barges-in on a prompt that contains important information, the IVR system interrupts the prompt to play a short announcement with the goal of re-enforcing the importance of listening to the entire prompt. The IVR system then resumes playback of the prompt, from the beginning or of a modified version.

Methods and apparatus for enforcing caller listening behavior on interactive voice response applications

The invention concerns method and system for pre-processing entries in a directory listings. An automated attendant or automated directory listings assistant may use the pre-processed entries. A first directory listings including one or more fields may be received. The one or more fields may be populated with entries including one or more symbol strings. A second directory listings including one or more fields may be received. The one or more fields of the second directory listings may be populated with entries including one or symbol strings. Entries in the one or more fields of the first directory listings may be correlated with entries in the corresponding one or more fields of the second directory listings. Entries, in the one or more fields of the first directory listings, which do not correlate with entries in the corresponding one or more fields of the second directory listings may be identified. The identified entries may be processed using a rule set corresponding to the field in which the entry is located. Based on the rule set, a corresponding confidence level for the processed entries may be determined. The processed entries having the corresponding confidence level meeting or exceeding a threshold may be automatically modified. The automatically modified entries may be outputted for processing. In alternative embodiments of the present invention, the processed entries having the corresponding confidence level below the threshold may be marked for operator confirmation.
