Passive Voice Biometrics

Text Independent Voice Biometrics, Tailored for Contact Center Applications


A Better User Experience

Passive Authentication improves the customer experience by seamlessly authenticating the user as they interact with your IVR, live agent, or self-service channel.


Stronger Authentication

A Protect your customers and business applications with layered security that uses biometrics to verify identity and prevent unauthorized access to information or accounts.

Compelling Cost Savings

Biometric authentication is proven to reduce operational and fraud costs. It enables you to quickly authenticate transactions in the IVR, for increased containment, or through the live agent for faster, safer service.

Something You Know, Something You Have,  Something You Are

Almost everyone on the planet has heard those words by now.  Information Security has been asking for 2nd factor or multi-factor authentication for a long time. What are you waiting for?

The LumenVox Passive Voice Biometric engine, is based on state-of-the-art text and language independent algorithms. The algorithms don’t care if you forget a piece of information (your SSN, date of birth, mother’s maiden name). The engine simply needs to hear your voice, within the IVR, talking with a live agent, or on a mobile device — saying anything, in any language.

Invisible Authentication

With LumenVox Passive Voice Biometric Authentication, the customer experience is quick, safe, and accurate.



As little as 30 seconds of speech required within a call center environment.



As little as 8 seconds of speech required within a call center environment.

How Passive Authentication Works

Whether your callers use an IVR or go directly to an agent — it doesn’t matter. The LumenVox Voice Biometric Engine is passively listening to the conversation, and uses biometrics to authenticate the caller. We can even authenticate callers in the IVR.

Your customers call you normally, and interact with the IVR and/or agent


During the call, the callers speech is analyzed and a voiceprint is created

IVR – callers who interact with a speech-enabled IVR can be authenticated in the IVR. CTI ensures that the authentication level (score) is passed along to the agent.

Agent – if the caller was not authenticated in the IVR, then the first words with the agent are analyzed and a voiceprint is created.


In the background, the newly created voiceprint is compared with the voiceprint on file

If it matches, then the caller is authenticated and a message is sent to the agent (green light).

If it doesn’t match, then a message is sent to the agent regarding the failed authentication (red light).

If there isn’t a voiceprint on file, then a message is sent to have the agent authenticate the caller manually. Once the caller authenticates manually, the voiceprint is placed on file to be used for future calls.
