Abstract: Embodiments described herein provide for a voice biometrics system execute machine-learning architectures capable of passive, active, continuous, or static operations, or a combination thereof. Systems passively and/or continuously, in some cases in addition to actively and/or statically, enrolling speakers. The system may dynamically generate and update profiles corresponding to end-users who contact a call center. The system may determine a level of enrollment for the enrollee profiles that limits the types of functions that the user may access. The system may update the profiles as new contact events are received or based on certain temporal triggering conditions.

Abstract: A computer-implemented method, system and computer program product for providing high quality speech recognition. A first speech-to-text model is selected to perform speech recognition of a customer's spoken words and a second speech-to-text model is selected to perform speech recognition of the agent's spoken words during a call. The combined results of the speech-to-text models used to process the customer's and agent's spoken words are then analyzed to generate a reference speech-to-text result. The customer speech data that was processed by the first speech-to-text model is reprocessed by multiple other speech-to-text models. A similarity analysis is performed on the results of these speech-to-text models with respect to the reference speech-to-text result resulting in similarity scores being assigned to these speech-to-text models.

Abstract: Embodiments of the present invention provide a computer system a computer program product, and a method that comprises analyzing a received voice command by identifying a plurality of contextual factors associated with at least one user in a plurality of users using a natural language processing algorithm; dynamically identifying the at least one user in the plurality of users based on an analysis of the identified contextual factors associated with the received voice command; transmitting the received voice command to another computing device within a plurality of computing devices associated with another user in the plurality of users; and generating a line of communication between the plurality of computing devices based on a correlation between a summation of a plurality of security factors and a predetermined threshold of risk associated with authenticating an identity of each user within the plurality of users.

Abstract: A voice-activated user interface for an application is described. The voice activated user interface invokes a speech recognition component to recognize audio input from a user. If the audio input is a command, then a validation component is invoked to determine whether to validate the command prior to execution.

Abstract: Apparatuses and methods for generating and verifying a voice signature of a message and computer readable medium thereof are provided. The generation and verification ends both use the same set of pronounceable symbols. The set of pronounceable symbols comprises a plurality of pronounceable units, and each of the pronounceable units comprises an index and a pronounceable symbol. The generation end converts the message into a message digest by a hash function and generates a plurality of designated pronounceable symbols according to the message digest. A user utters the designated pronounceable symbols to generate the voice signature. After receiving the message and the voice signature, the verification end performs voice authentication to determine a user identity of the voice signature, performs speech recognition to determine the relation between the message and the voice signature, and determines whether the user generates the voice signature for the message.
