SPEAKER VERIFICATION METHOD

摘要

A method to enable a user of a system to obtain access to one or more services, for example, to enable a caller to access some information on a remote server. The system first prompts the caller to identify himself by entering a subscriber code. A speaker verification is then made using a voice comparison between the caller's voice and a voice reference associated with the subscriber the caller claims to be. Access to the requested services is given if the outcome of said voice comparison is positive. If the system does not store a sufficiently good voice reference to verify the identity of the subscriber the user claims to be with a predetermined degree of reliability, the caller is prompted to enter a confidential PIN code. If the PIN code entered is correct, access to the requested services is given and a new voice reference is stored.
