URU Plus - a scalable component-based speaker-verification system for BT’s 21st century network

M Pawlewski and J Jones




Identity security is an issue that affects us all. In many everyday transactions, you have to prove that you are you (URU). BT has already established a market position with the award-winning URU product, that provides identity validation. A major extension to URU is URU Plus. This allows users to verify their identity through the use of speaker-verification technology. Following initial identity validation via URU, users are no longer required to produce documentary evidence for identity verification, but can instead verify themselves using their voice. The URU Plus system is a component integrated into BT´s 21st century network authentication capability. It uses state-of-the-art voice verification technology and is accessed via a Web Service API.
