Using Nuance Voice Biometrics to authenticate callers

Deutsche Telekom creates secure, seamless experiences with Nuance

Deutsche Telekom—one of the world’s leading telecommunications companies—wanted to find a way to offer customers fast, secure, and seamless experiences while reducing the pressure on its agents to authenticate customers.


Deutsche Telekom uses Nuance Voice Biometrics as part of Nuance Gatekeeper to authenticate callers every time they get in touch, using just their voice. Nuance Voice Biometrics uses more than 100 physical and behavioral characteristics, including accent and rhythm, to create unique voiceprints for each customer.
