    “Aculab’s VoiSentry is a best-in-class product that we are proud to have as part of our product ecosystem. VoiSentry removes the friction traditionally associated with the ID&V process by using an end user’s unique voiceprint as identification. Not only does this provide our clients with the highest level of security within their contact centres, but it also improves the overall customer experience through a faster and more natural ID&V process.”
