VERIFICATION OF USER PRESENCE DURING AN INTERACTIVE VOICE RESPONSE SYSTEM SESSION

摘要

In those transactions requiring the approval of two or more users, users can perform verification of identity and then completion of desired transaction using an IVR system. The combination of two or more user voice prints previously collected during an enrollment phase can be used for verification of parties to the transaction. During a subsequent verification phase of the IVR system, the users can speak their own password phase when prompted to do so during a defined period of time and the IVR system captures them in a captured mixed voice print. Verification can then be provided by comparing the captured mixed voice print with a joined voice reference model built from stored voice reference models.
