Use Case

Voice biometric authentication

Smartly replace traditional authentication methods and offer your customers a secure authentication experience with something unique, personal and non-transferable: their voice.

Start by listening to what your customers are saying and leave behind …

Outdated passwords

Passwords and security questions are weak authentication methods that sophisticated fraudsters can easily replicate.



Never-ending identifications

Avoid complex authentication processes that damage customer perception of your company. Avoid knowledge-based call authentication and decrease average talk time (ATT).


Identity theft

Our technology distinguishes a live voice from a manipulated or recorded one. Therefore, agents can provide customised service with the conviction that the individual on the other side is not a fraud.


Multiple identification systems

With voice, a single sentence is enough to identify your customers. Implement a fast and secure identification system that does not give rise to confusion.


You are what your voice says about you

Voice is special and unique. It is an extension of the person that replaces something you know for something you are. Each customer´s voice is unique and depends on their anatomy and speech patterns.

Is there a better way to identify than with something that is part of you?

voice biometric authentication technology

1. Register your voice


Firstly, we need to register your voice to recognise it. To do this, you will be requested to provide a voice sample, which the system will analyse to create a template biometric.





2. Talk


At the moment of identification, you will asked to speak. It is the time when our software compares your voice with the previously registered one.



3. Identified!


Thanks to high-precision AI-based technology, voices are matched by verifying the speaker with just one sentence.
