Nuance Voice Biometrics Chosen by SK Telecom to Offer Easy and Secure Authentication

With Nuance Voice Biometrics, SK Telecom Aims to Improve Customer Experience; Becomes First in Region to Authenticate Customers by the Sound of Their Voice

BURLINGTON, Mass., – April 28, 2015Nuance Communications, Inc. (NASDAQ: NUAN) today announced that SK Telecom, the leading mobile service provider in South Korea, has deployed Nuance’s voice biometrics to provide an easy and secure authentication process for its customers.

SK Telecom turned to Nuance’s VocalPassword voice biometric solution to offer an innovative solution to its customers, allowing them to authenticate into their accounts using the sound of their voice. This solution eliminates the need for customers to be asked intrusive security questions and instead results in a quick, secure and convenient experience.

SK Telecom, the leading mobile service provider in South Korea with over 28 million subscribers, has become the first organization in the region to offer voice biometric technology in the call center. Previously, customers were asked a number of questions to verify their identity when calling into the contact center, creating a lengthy and uncomfortable process. Realizing the value of their customers’ time, SK Telecom sought to transform the experience by offering a simple yet secure method for gaining access to accounts. Now, when a customer dials into the contact center, they are asked 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 about their inquiry or request. This innovative solution allows for a quick, easy and secure customer experience.

Voice biometrics offers a proven alternative for organizations to increase security while also vastly improving the customer experience by making the authentication process more natural and intuitive. “Providing our customers with an unparalleled experience is our top priority” said Ahn Keun, Senior Vice President and Head of Customer Experience Management (CEM) Office at SK Telecom. “Voice biometrics is transforming the way we interact with our customers, allowing them a more convenient experience while also keeping their information secure. Customers enjoy calling into the contact center knowing that they are no longer bothered with intrusive and lengthy questioning.”

“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, Enterprise Division, 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 globally by other large organizations such as ING Netherlands, Tangerine Bank, Tatra Banka, Turkcell, Banco Santander Mexico and Vodacom South Africa.

Around the world, voice biometrics is quickly becoming an accepted form of authentication which has proven to be both secure and convenient. New data from Opus Research shows that the voice biometrics authentication market is poised to grow from $200M (2013) to $750M globally in 2017. Nuance voice biometrics technology leads the industry, with over 50 million voiceprints deployed by its customers, representing over 80% of the commercial market.
