Your Voice is your identity

What is Voice Biometrics?

Voice biometrics is a technology used to match personal voice pattern and verify the speaker's identity using just voice. In essence, it listens to a human's voice and determines who that person is. To identify a person, voice biometrics technology captures a person's voice and compares the captured voice characteristics to the characteristics of a previously created voice pattern. If the two match, then the voice biometrics software will confirm that the person speaking is the same as the person registered against the voice pattern.
