The potential for versatility, scalability and convenience presented by voice biometric solutions has helped the segment grow rapidly in recent years, with major banks and governments deploying them in contact centres and mobile deployments being attached to fintech apps. Case studies of bank implementations by major US biometrics firms have shown that the technology can save financial institutions significant sums, while cutting authentication times down to seconds. The future could be even brighter for voice, with the contactless interface and flexible access potential offered by the modality making voice biometrics seemingly a no-brainer for Internet of Things applications. But like other biometric modalities there are always challenges – for voice in a mix of scenarios, background noise can confuse algorithms, threatening usability. Is “spoofing” the tech as easy as playing back a recorded, or even morphed, sound?
