What is Voice Biometrics

Voice biometrics is a technology used to extract personal voice patterns and verify the speaker's identity using just voice. In essence, it listens to a human's voice and determines who that person is.

There are many voice characteristics that can be measured to determine who you are based on your voice. To identify a person, voice biometrics technology captures a person’s voice and uses algorithms to compare the captured voice characteristics to the characteristics of a previously created voice print. 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 print.

Frequently Asked Questions

  1. 1. Could someone gain access to my voice print and hack into my account?

    A voice biometrics is a numerical representation of the sound, pattern, and rhythm of an individual's voice. Voice biometrics or “voice print,” is as unique to an individual as a palm or fingerprint. Voice biometrics technology is the ability to extract an individual’s voice print and to use the extracted voice print to verify the speaker’s identity by comparing the voice to the voice print. The voice print which is a numerical representation cannot be emulated from the file and cannot be reused in any form.

  2. 2. Can someone record my voice and use that to access my account information?

    No. Citi uses Text Independent or Free Speech voice biometrics technology, which does not require any vocal password. The verification will be conducted using your voice print whilst you are having a conversation with our CitiPhone officer.

  3. 3. What if someone has the same voice as me?

    No two voices are the same; even identical twins have different voice prints. Over 70 body parts are involved in creating speech. Each human voice and extracted voice print is therefore unique.
