Voice Fraud Is the Fastest-Growing Attack Vector


AI voice cloning tools are cheap, fast, and widely available. Attackers need just 3 seconds of audio to
generate a convincing synthetic voice.

Protecting Every Sector That Relies on Voice

Banking & Finance

AI vishing attacks impersonating bank reps, wire transfer fraud, and IVR authentication bypass.

Healthcare

Patient impersonation, prescription authorization fraud, and insurance verification attacks.

Retail & E-Commerce

Refund and return fraud, gift card scams, and account takeover via voice channels.

Insurance

Synthetic voice claims fraud, fraudulent policy changes, and impersonation of policyholders.

Higher Education

Financial aid fraud, student record impersonation, and registrar call fraud.

Enterprise Contact Centers

AI-assisted social engineering, executive impersonation (vishing), and high-volume inbound fraud.

Frequently Asked Questions

Most customers are live within 2–4 weeks. Velma integrates via REST API with any telephony platform — no custom hardware or model training required.

How quickly can Velma be deployed?
Does Velma store or retain audio data?

No. By default, Velma processes audio ephemerally — it is analyzed and discarded. Private cloud and on-prem options are available for regulated industries.

What’s Velma’s false positive rate?

Velma-2 achieves an F1 score of 0.96 on independent benchmarks, meaning extremely low false positives. Thresholds are configurable to match your risk tolerance.

Does Velma work on recorded calls as well as live calls?

Yes. Velma supports both real-time streaming and batch analysis of recorded audio files, giving you full coverage across your call library.

What is AI voice deepfake fraud — and how is it different from vishing?

Vishing is social engineering over the phone — tricking someone into revealing information or authorizing a transfer. AI voice deepfakes add a synthetic voice layer on top: attackers clone a trusted person’s voice to make the scam convincing. Velma detects both the synthetic voice signature and the behavioral fraud patterns that accompany it.

Can Velma distinguish legitimate synthetic voice users (e.g., assistive technology)?

Yes. Velma’s conversational analysis layer looks beyond voice type to intent, urgency cues, scripted phrasing, and turn-taking anomalies — distinguishing fraudulent callers from users who rely on assistive voice technology. This prevents false positives that would harm accessibility-dependent customers.

Does Velma detect video deepfakes?

Velma analyzes audio only — by design. The overwhelming majority of voice fraud happens over phone and contact center channels, not video. Purpose-built audio analysis delivers higher accuracy and lower cost at scale than generalist multimodal tools that try to do everything.
