SK Telecom (SKT) has signed a deal to use Pindrop’s AI-based voice authentication technology in its call centres to reduce customer consultation and wait times, with plans to commercialise the service by combining it with its own technology.

SKT began piloting the cloud-based service in 2021 and recently verified its effectiveness through evaluations with customers. The technology can identify a user’s unique voice and authenticate an individual after a simple conversation without additional authentication. According to SKT, the service can register voiceprints with a “maximum accuracy of 98%” and is “widely used by many global companies” including Verizon and BT.

In addition to its call centres, SKT will deploy the service on devices requiring personal authentication including access control and biometric security.

SKT expects the voice recognition technology to be used for authentication across applications including vehicle access and online shopping.
