Frequently Asked Questions.

Can someone gain access to my voice print and hack into my account?

Voice Biometrics is a numerical representation of the sound, pattern and rhythm of an individual's voice. Voice Biometrics or "voice print" is unique to an individual, similar to fingerprint. Voice Biometrics technology has 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 print. The voice print, which is a numerical representation, cannot be reverse-engineered/ reused in any form.

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

No. Citi uses Text independent or Free Speech Voice Biometric technology. The verification will be conducted using your voice print whilst you are having a conversation with our CitiPhone officer.

2 / 10
What if someone has the same voice as me?

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

3 / 10
What if I have a cold which affects how I sound?

There may be conditions that may affect the authentication of your voice, though with a slight cold, your voice can still be authenticated. Should the authentication process be affected by a change in your voice, standard verification questions will be prompted to safe guard your confidentiality.
