VoiceDNA

Verify identity in seconds. With just a voice.

AI-powered voice biometrics for authentication, anti-fraud, and deepfake detection, built for enterprise.

Overview

Eliminate the friction of manual identity verification without sacrificing security. VoiceDNA authenticates customers through their unique voiceprint during the natural flow of conversation, requiring no security questions, no OTPs, and no passwords.

Built with entirely proprietary in-house deep learning models, VoiceDNA continuously guards against the most sophisticated modern fraud vectors, including AI voice cloning, synthetic speech, text-to-speech (TTS), and physical replay attacks.

What it does

Traditional knowledge-based verification is vulnerable to modern cyber threats, while multi-factor methods add friction to the user experience. Transcription errors, failed biometric verifications, and missed compliance keywords mostly trace back to an audio signal that was never clean to begin with.

VoiceDNA eliminates these challenges by performing high-accuracy speaker verification, liveness detection, and active audio quality assessment on a single audio stream, returning authentication decisions in sub-second response times without disrupting the customer interaction.

Key Features

High-Accuracy Speaker Verification
Verifies genuine users while rejecting impostors with measurable precision. The engine is independent of spoken language, speaker age, or gender. High-accuracy speaker verification validated in enterprise environments.
Anti-Spoofing and Liveness Detection
Continuous evaluation of raw waveforms to detect voice clones, synthetic speech, TTS, and physical replay attacks before they reach sensitive account actions.
Fast Enrolment and Sub-Second Verification
Requires from just 10 seconds of a voice sample to register a unique voiceprint, and from just 4 seconds of live audio for each subsequent authentication attempt.
Audio Quality Assessment
Automatically filters invalid samples before processing, detecting and screening out audio with high background noise, low volume, or multi-speaker overlap to prevent poor enrolments.
Noise-Robust Recognition
Maintains reliable authentication performance in real-world noisy environments. Built to set a new benchmark for reliable voice authentication in noisy, real-world enterprise environments.
Continuous Voiceprint Enrichment
The deep learning model accumulates real-world interaction data over time, allowing individual recognition accuracy to improve with each successful session.
Flexible Enterprise Deployment
Supports both real-time audio stream integration and REST API integration. Models run natively on CPU without requiring GPU, simplifying on-premises or cloud deployment while satisfying data sovereignty requirements. Operates reliably on 8kHz telephony audio and at 16kHz and above.

Seamless Authentication Across Every Channel

VoiceDNA identifies customers within the opening seconds of natural conversation before the interaction has reached its primary purpose. Rather than interrupting service to ask verification questions, the system confirms identity in the background and surfaces the result to your agent or automated system before any sensitive action is taken.

Authenticate customers within seconds of natural conversation without interrupting the service experience.
No passwords, no security questions, and no additional verification steps for the customer to complete.
Deploy across contact centres, mobile banking apps, and automated transaction channels.

Stronger Security Against Modern Fraud

VoiceDNA is designed for the modern fraud landscape, where attackers use generative AI to clone voices, replay recorded audio, and impersonate customers with tools that defeat knowledge-based verification entirely.

Detect physical replay attacks using pre-recorded audio files.
Identify AI-synthesised, TTS, and voice-cloned speech before it reaches a sensitive account action.
Reduce the risk of unauthorised access without adding friction for legitimate customers.

Use Cases

Contact centre authentication
Verify callers passively while the conversation continues.
Mobile banking and digital channels
Voice-based identity confirmation integrated into core banking apps and IVR flows.
Insurance onboarding and claims
Confirm customer identity at every critical point in the policy lifecycle.
Anti-fraud at scale
Flag and block automated calls where the voice does not match the enrolled voiceprint or where synthetic audio is detected.
