METHOD AND SYSTEM FOR NON-INTRUSIVE SPEAKER VERIFICATION USING BEHAVIOR MODELS

摘要

A system and method for verifying user identity, in accordance with the present invention, includes a conversational system (114) for receiving inputs from a user (110) and transforming the inputs into formal commands. A behavior verifier (118) is coupled to the conversational system (114) for extracting features from the inputs. The features include behavior patterns of the user. The behavior verifier (118) is adapted to compare the input behavior to a behavior model (214) to determine if the user is authorized to interact with the system.
