Verify every customer. In seconds. With just their voice.
Passive biometric authentication for contact centres, digital banking, and insurance. No passwords, no OTPs, no friction.
The problem
Manual identity verification is one of the most expensive and frustrating steps in financial services. Knowledge-based authentication forces customers through security questions they half-remember while an agent waits. OTPs add a step customers resent. And none of it stops a sophisticated attacker who has researched their target.
The NamiTech approach
VoiceDNA authenticates customers using one of the most natural and difficult-to-replicate forms of identity: their voice. Enrolment takes only seconds of natural conversation. Verification happens in the background before the interaction has reached its purpose, with the result delivered to your agent or automated system instantly. The customer experiences a seamless conversation. The system has already confirmed who they are.
How It Works
Step 1
Enrol
The customer's unique voiceprint is captured using just 10 seconds of natural speech. Active (text-prompted) or passive (free speech) enrolment modes are both supported. One-time process. No dedicated sessions required.
Step 2
Verify
On every subsequent call or digital interaction, VoiceDNA matches the voice against the enrolled voiceprint in real time. Authentication is completed quickly and the conversation continues without interruption.
Step 3
Protect
The system continuously evaluates voice authenticity throughout the interaction, detecting AI voice cloning, synthetic speech, and replay attacks in real time. Multi-speaker detection helps ensure high-quality voiceprint enrollment. Audio quality assessment filters invalid samples automatically.
