The voice recognition service authenticates customers based on their speech patterns and allows them to execute banking transactions through the bank's call centre, the bank said in a statement issued here.
Customers, in general, use various means of authentication like entering card numbers, answering security questions and entering a personal identification number (PIN) to carry out a phone banking transaction.

"Their voice will now act as the password for banking transactions through the call centre," the statement said, adding that the service is secure.
Over 33 million savings bank and credit card customers will be able to use the service.
"Our decision to invest in this new technology was primarily driven by the objective of enhancing the everyday banking experience of our customers," its managing director and chief executive Chanda Kochhar said.
