Biometrics + Security Questions

deepVB® Workflow

DiaManT® NLU applications mix traditional
security questions into the Conversational
Voice User Interface design of the Virtual

deepVB® allows customers to skip answering
traditional security questions if there is a
sufficient confidence score of the Voiceprint

How deepVB® Works

User authentication is performed in real-time in the background via the scoring of the
speakers voice-print match, from first dialog step, and during every step until hang-up.

Upon a user starting a call with DiaManT®…


deepASR® samples the speaker’s voice, and if there is enough audio sample,
computes the speaker’s voiceprint in real time.


DiaManT® compares the speaker’s current voiceprint with the verified voiceprint
stored in the database.


The comparison produces a verification result in the form of a “bioSV
Confidence Score”.


bioSV Confidence Score is used by DiaManT® to drive the conversation with the
customer according to the business logic; deliver self-service, transfer to live agent,
or ask additional traditional security questions.
