Voice Biometrics

Overview

Voice biometrics uses the unique features of an individual’s voice (tone, pitch, rhythm, and accent) to authenticate their identity. It is used in call centers, banking apps, and secure systems as a convenient authentication method.

Voiceprints are compared against enrolled samples to verify legitimacy. Regulators accept voice biometrics when paired with liveness detection and multi-factor controls.While it improves customer experience, voice biometrics can be vulnerable to replay or deepfake-based attacks. Institutions enhance resilience with PAD and anomaly detection. It supports compliance by enabling strong customer authentication and reducing fraud in remote channels.
