SK Telecom deploys Nuance voice biometrics for secure customer authentication


South Korean mobile service provider SK Telecom has deployed Nuance Communications voice biometrics solution to provide an easy and secure authentication process for its customers.

As a result, SK Telekom customers can now log into their accounts using the sound of their voice, eliminating the need to answer intrusive security questions.

SK Telecom, which has over 28 million subscribers, is the first organization in South Korea to offer voice biometric technology in the call center.

When customers call into the contact center, they will be prompted to speak the predefined phrase, “At SK Telecom, my voice is my password,” to be authenticated into their account and then speak with a representative regarding their inquiry or request.

The voice biometrics solution allows for a quick, easy and secure customer experience, while increasing overall security.

“When it comes to authentication, we’ve seen that PINS, passwords and security questions are leaving accounts vulnerable and can no longer be considered a safe and secure method,” said Robert Weideman, executive vice president and general manager of the enterprise division at Nuance. “By turning to voice biometrics, SK Telecom will be able to differentiate itself from other businesses by offering a truly innovative experience that is proven to be effective.”

Nuance’s voice biometrics solutions have been adopted around the world by various large organizations, including ING Netherlands, Tangerine Bank, Tatra Banka, Turkcell, Santander Mexico and Vodacom South Africa.

Most recently, Indian financial institution ICICI Bank deployed voice recognition technology from Nuance Communications to provide biometric authentication for telephone banking customers to enable them to securely conduct a range of transactions over the phone.
