Auraya Enhances ArmorVox2015 Random Challenge Response

July 10, 2015

Building on ArmorVox’s highly secure text-prompted voice biometric function; Auraya has introduced a new feature; a simple four digit random challenge response.

Designed to confirm that the speaker is alive (and not a tape recorder); this feature enables ArmorVox to generate a random four digit challenge response which is different everytime the caller uses the system. The speaker then has to repeat the random four digits with the correct voice to confirm that they are a live person (and not a recording).

The technology uses Auraya’s patented Speaker Adapted Core Voice Biometric algorithms which offers superior performance and accuracy and which can be tuned and optimised to the accent and language of the population of enrolled speakers.

This new feature allows Auraya’s partners to implement a very simple but highly effective four digit random challenge response into solutions to defeat tape recorder attacks in call centre, telephone self-service and smartphone security applications.
