Voice biometrics is the measurement of the unique characteristics of an individual’s voice. These characteristics, which are based on an individual’s vocal tract shape and motion patterns, are converted into a mathematical formula known as a voiceprint. This is accomplished by acquiring a live voice sample from an individual and applying a specialized algorithm to convert the sample into a digitized "base" voiceprint.
The voice biometric identity verification process is conceptually similar to comparing fingerprints, and no two voiceprints are exactly the same. By comparing a "sample" voiceprint with the "base" voiceprint, one is able to positively verify the identity of any enrolled individual.
