Auraya Systems announced that it has been granted patent protection in the USA from the U.S. Patent Office for its core Speaker Adaptive Voice Biometric technology, quickly following its patent from the Australian Patent Office.
The announcement comes a month after Auraya’s win of the “best and most innovative solution” in the iAwards new product category for its flagship voice biometrics product ArmorVox10.
Assigned US Patent No. 8,775,187, Auraya’s voice biometric technology provides the foundation of its ArmorVox language independent voice biometric product.
The technology enables Auraya to automatically boost performance to the language, accent and telecommunications environment into which it is deployed.
“Unlike our competitors that use a fixed global threshold; ArmorVox automatically sets thresholds and other parameters optimized to the security performance for each speaker enrolled in the system,” said the inventors, Dr Habib Talhami and Dr Clive Summerfield. “Whilst voiceprints created in controlled laboratory conditions exhibit relatively uniform performance; in ‘The Real World’ noise, interference, distortion and speaker behaviour often lead to voiceprints with widely varying security performance”; explained the inventors. “Consequently, a fixed global threshold cannot compensate for these variations which lead to sub-optimal performance in commercial environments.”
Auraya tackled this issue by developing new speech processing algorithms, which enables it to “measure the performance of each voiceprint enrolled in the system and automatically adjust settings optimized for each individual speaker,” said Dr Talhami.
AmorVox was originally developed for Auraya’s partners worldwide, and has since been deployed to some of the world’s largest voice biometric solutions for governments, banking, help desks, call centers, smartphone and national security.
