National Australia Bank customers will no longer have to remember PINs and passwords thanks to the implementation of a voice biometrics system for telephone banking.
Once callers have registered their unique voiceprint in the system, they can recite their individual account number over the phone to have their identity verified.
This will enhance security and privacy for customers, according to the bank.
"Our objective is to provide customers with a more convenient, faster and easy-to-use telephone banking experience while simultaneously improving identity security," said NAB's personal banking program manager for the direct channels speech program, Sam Jackel.
The voice biometric technology was developed by the Salmat-owned VeCommerce.
Telstra managed coordination and deployment of the solution which integrates into NAB's existing telephony infrastructure.
The carrier will also provide first level support.
In March, NAB deployed a separate VeCommerce speech recognition system to route calls to its main customer service number.
