Challenges We Solve with AI-Powered Voice Biometric Authentication Software

Our AI-powered voice biometric authentication software helps security and customer experience teams solve key challenges and helps you strengthen security while enabling faster, frictionless user verification. Here are the top challenges we can help you solve.

Rising Account Takeover Fraud

Credential stuffing, phishing kits, and SIM swap attacks are bypassing passwords and SMS OTP at an industrial scale. We build voice biometric authentication software that binds identity to the user’s voiceprint, so stolen credentials alone cannot unlock an account.

Synthetic Voice Attacks

Off the shelf voice AI tools have made fake voices easy and convincing. Our anti spoofing layer checks liveness on every utterance, stopping text to speech use, replay attacks, and deepfake audio before the session is approved.

Slow Contact Center Authentication

Agents waste 45 to 90 seconds per call running knowledge-based verification. Our biometric voice authentication system authenticates passively in the first 20 to 30 seconds of natural conversation, cutting average handle time and killing KBA fatigue.

Cross-Channel Authentication Gaps

Customers who authenticate in the mobile app get challenged again on IVR or the branch kiosk. We engineer channel-agnostic voice biometrics software that recognizes the same voiceprint across telephony, web, mobile, and IVR without retraining models per channel.

High False Rejection Rates

Generic vendor models often underperform on non native speakers, regional accents, and older adults. Our voice biometrics AI is custom-trained on your actual user base demographics, driving false rejection rates down and protecting inclusive access.

Voiceprint Compliance & Privacy

Voiceprints are biometric data under GDPR, BIPA, and CCPA. We architect consent capture, encrypted voiceprint storage, anonymization, and automated deletion workflows into the platform from day one, so your legal team is not retrofitting compliance later.

Voice Biometrics Software Projects We Have Delivered

Here are some of our recent deployments of AI-powered voice biometric authentication software across retail banks, global telcos, and health insurance providers. Each one is a live production system, built with a custom-trained model and delivering measurable improvements over the client’s starting baseline.

Voice Biometric Authentication for a Tier-1 Banking Contact Center

Industry: Retail Banking

Tech Stack: Python, PyTorch, Kaldi, React, PostgreSQL, AWS, Genesys Cloud

A North American retail bank lost 72 seconds per call to knowledge-based authentication while ATO fraud climbed. We built a custom voice biometric system integrated into their Genesys IVR, enrolling customers passively and authenticating callers in under 2 seconds. As a result, handle time dropped sharply and ATO incidents fell to near zero.

68% Reduction in authentication time per call
92% Drop in confirmed ATO fraud on voice-authenticated sessions

Continuous Authentication Platform for a Global Telecom Operator

Industry: Telecommunications

Tech Stack: TensorFlow, Python, Node.js, Kafka, MongoDB, GCP, Twilio

A multi-country telco wanted to stop SIM swap and port-out fraud at the source. We built continuous voice authentication that checks the caller’s voiceprint on every sentence and triggers step-up verification when scores drop. As a result, false rejection rates stayed under 1.5% across 11 countries with region-trained models.

Multi-Channel Voice Authentication for a Health Insurance Provider

Industry: Health Insurance

Tech Stack: Python, FastAPI, React, Redis, Azure, HIPAA-ready voiceprint vault

A health insurance provider needed a voice biometric layer working identically across IVR, member portal, and mobile app. Their legacy vendor forced separate enrollments per channel, which members abandoned. We delivered unified passive enrollment with BIPA and HIPAA-compliant storage. As a result, CSAT scores improved within two months of go-live

Frequently Asked Questions

Still have questions?Let's talk

How accurate is the software, and how do you measure it?

We usually aim for around 99.5% voice matching accuracy, and the system verifies users in under 2 seconds in real scenarios.
To measure this, we use basic metrics:

  • False Acceptance Rate means a wrong person gets access.
  • False Rejection Rate means a real user gets blocked.
  • Equal Error Rate balances both.

We don’t test this on lab data. Everything is measured on your actual users, so the results match what really happens in production.

How long does it take to deploy a custom voice biometric authentication system?

Most full deployments take around 12 to 20 weeks. It depends on how many channels you have, how many languages you need, and how deep the integrations go. If you are starting small, like just IVR, you can go live in about 8 to 10 weeks. Bigger rollouts across countries usually take around 3 months if planned well.

How is a custom-built solution better than off-the-shelf vendors?

Most vendors give the same model to every client. That means it is not really tuned for your users, your fraud patterns, or your setup. With a custom build, everything is trained on your data. You also own the system fully. No per-use fees, no vendor lock-in, and no waiting on someone else’s roadmap when you need changes.

Is your voice biometric software compliant with GDPR, BIPA, CCPA, and HIPAA?

Yes, we build compliance into the system from the start. Not something added later. Voiceprints are encrypted, consent is recorded, and deletion is automated. Also, we don’t store raw audio. Voiceprints are stored as mathematical data, which is much safer. For healthcare and US use cases, we align with HIPAA and BIPA requirements properly.

Will it work for users with colds, accents, or non native English speakers?

Yes, you do not need to worry, it still works. The system is trained on your real user base, so it handles different accents and speaking styles better. Even if someone has a cold or voice change, it usually works because it looks at deeper voice traits, not just how someone sounds on the surface.

Can your software integrate with our existing systems?

Yes, it connects with the most common platforms like IVR, CRM, and contact center tools. We support systems like Genesys, Avaya, Cisco, Twilio, Salesforce, and more. You don’t need to replace your current setup. It just fits into what you already use.

What happens if a voiceprint is stolen or leaked?

Even if that happens, it is not very useful to an attacker. We do not store voiceprints as raw audio. They are stored as encrypted data and cannot be turned back into a voice recording.
On top of that, we verify real human presence during every authentication. This means replayed or synthetic attempts are detected and blocked in real time.

How much does it cost to build custom voice biometric authentication software?

The cost depends on how complex your setup is. The good part is that there are no ongoing per-use charges. You own everything. So as you grow, your costs don’t keep increasing like vendor platforms. Contact us today to get a clear estimate based on your requirements.
