Biometric Voice Authentication

Introduction:

Biometric Voice recognition system calculates vocal measurements of a person’s vocal tract. Sophisticated algorithms convert these measurements into a voice print – which is unique in nature.

Biometric Voice Authentication System is a biometric security system that uses spoken words by user to verify claimed identities over the phone or web.The core Voice authentication system technology is very different from other voice recognition systems that depend on comparing recordings or wave patterns.This uniqueness of Voice Authentication process provides the biometric device to deliver a range of ultra reliable and highly secure voice verified services.

Working of Biometric Voice Authentication:

Biometric Voice Authentication System involves the use of pitch, tone and rhythm of the speech to establish a unique pattern. This identity is recorded in the database of the biometric system for reference. Whenever a voice sample is fed as input for access, the matching is done for identification & authentication.

Factors Affecting the Accuracy of Biometric Voice Authentication System:

The accuracy of voice-based biometric authentication system can be affected by several factors. like illness, age, difference in the microphone setup, telephones,background noise.These parameters can affect the accuracy of authorization.

The accuracy of voice biometric system can be calculated on parameters like False Acceptance Rate (FAR), failure to enroll(FTE) & False Rejection Rate (FRR).
