VoiSentry: Flexible, Scalable, Speaker Verification with Integrated Multi-Factor Authentication.
VoiSentry is Aculab''s new Speaker Verification system featuring an integrated multi-factor authentication capability. We show how this can increase security and mitigate against spoofing. Its flexible architecture can be exploited to build a complete authentication solution, which is able to cope with even narrowband telephone speech. VoiSentry also employs a scalable, multi-tenant system framework, allowing resources to be shared between clients, while keeping the data private.
