Live Synthetic Audio Detection — Incoming Call
A UAE bank lost $35 million in a single CEO voice fraud call. A UK energy firm lost $243,000. These are documented, confirmed cases — not projections.
Capital calls, closing wires, and vendor payments are routinely authorized by voice. AI voice cloning turns every phone-authorized wire into a potential fraud vector — with no existing tool to verify the voice.
AI voice cloning attacks grew 2,400% year-over-year. No other fraud vector is growing at this rate. Every executive with public audio — earnings calls, podcasts, conferences — is a cloning target.
Organizations have extensive controls for verifying identity by email. They have almost none for phone calls. When you hear a voice you recognize, you trust it — and AI voice cloning replicates exactly that.
Vicall is a second secure VOIP line with built-in synthetic audio detection. On-device AI flags AI-generated voice audio in real time — before any wire instruction is confirmed. MSPs deploy it to their clients.
Finance teams, PE/VC operations staff, law firm bookkeepers, AP departments — anyone who receives voice-authorized instructions to move money. AI voice clones fool these employees 90–95% of the time.
AI voice cloning generates a convincing replica of any person from 3 seconds of audio — in real time, on a live call. It fools trained employees 90–95% of the time. No existing business phone system can detect it. Your clients are exposed on every call.
Vicall is a second secure VOIP line with built-in synthetic audio detection. You deploy it to your clients. Their sensitive calls route through Vicall's on-device AI — which flags synthetic voice audio in real time, before a wire instruction is confirmed. Nothing ever leaves the phone.
See Vicall detect a real-time AI voice clone scam mid-call — on-device, zero latency, no cloud. This is what deepfake call protection actually looks like.
How CEO voice fraud, wire transfer scams, and closing wire theft work — and the only technology that stops them. Written by the Vicall team.
AI voice fraud is a fast-moving space. Here are the precise definitions of the terms you need to know.
The use of machine learning to synthesize a convincing replica of a specific person's voice from a short audio sample — as little as 3 seconds. The cloned voice can speak any text in real time and is acoustically indistinguishable from the original. Used in phone scams to impersonate trusted contacts.
A phone call in which the caller's voice has been synthesized or replaced by AI to impersonate a real person. Deepfake phone calls are the primary delivery method for AI voice cloning scams, targeting victims who trust the person being impersonated.
Any technique used to make a caller sound like a different person. Includes AI voice cloning, voice conversion models, text-to-speech impersonation, and replay attacks. Distinct from caller ID spoofing, which fakes the phone number rather than the voice.
The falsification of the phone number displayed to the call recipient, making the call appear to originate from a trusted number such as a bank, government agency, or family member. Caller ID spoofing attacks have risen 340% and render the displayed number meaningless as a trust signal.
The process of identifying AI-generated speech artifacts in live call audio. Instead of asking who the speaker is, synthetic-audio detection answers whether the voice itself was machine-generated.
A live probability value representing how likely incoming audio is synthetic. Lower scores indicate human speech patterns, while higher scores indicate likely AI-generated speech and trigger alert states.
Machine learning inference performed locally on a user's device rather than transmitted to remote servers. On-device AI enables real-time processing with complete privacy — no data leaves the device. Vicall uses Apple's Neural Engine and CoreML to run voice clone detection entirely on-device.
The use of voice-based impersonation to psychologically manipulate a victim into taking an action — wiring money, sharing credentials, or disclosing private information. AI voice cloning has made voice social engineering dramatically more convincing and scalable. Attacks are up 890% year-over-year.
How Vicall works, how MSPs deploy it, and what it means for the businesses you protect.
Vicall is a second secure VOIP line with built-in synthetic audio detection. It's deployed by MSPs to their business clients. Sensitive calls — wire authorizations, deal confirmations, financial instructions — route through Vicall's secure line, where on-device AI detects AI-generated voice audio in real time. Nothing ever leaves the phone.
Vicall's on-device AI model analyzes incoming call audio for synthetic markers — artifacts and patterns that distinguish AI-generated speech from a real human voice. The detection runs continuously for the full duration of the call and surfaces a live indicator: REAL VOICE or SYNTHETIC DETECTED. It catches 90–95% of AI voice clones that would fool a trained employee. No enrollment, no setup — works from the first call.
Vicall deploys as a managed service — a second secure VOIP line added alongside the client's existing phone system. It fits naturally into your existing stack. You provision the line, the client uses it for sensitive calls, and the on-device AI handles detection automatically. No complex integration, no voiceprint enrollment, no training period. It works from day one.
Any business where phone-authorized transactions carry financial risk. The highest-value deployments include law firms (trust account disbursements, closing wires), PE/VC firms (capital calls, deal wires), corporate finance and AP teams (wire transfers, vendor payments), and real estate (closing disbursements). These are the businesses where a single fraudulent call can mean millions in losses.
AI voice cloning uses machine learning to synthesize a convincing replica of a person's voice from as little as 3 seconds of audio. The cloned voice can be used in real-time phone calls to impersonate anyone — an executive, a client, a partner. In 2024, over 3.1 billion deepfake voice calls were placed worldwide, costing businesses $25 billion annually. These clones fool trained employees 90–95% of the time.
Never. Vicall is built on a zero-cloud architecture. All synthetic audio detection and AI inference runs entirely on the device's Neural Engine. No audio, no call metadata, no analysis results are ever transmitted to any server — not ours, not yours. This is a hard technical guarantee, not a privacy policy promise. Your clients' calls stay on their phones.
No. Vicall detects synthetic audio — not specific speakers. There are no voiceprints to build, no contacts to enroll, no training period. The detection model works from the very first call. If the incoming audio is AI-generated, Vicall flags it regardless of who the caller claims to be.
AI voice fraud is the fastest-growing attack surface your clients face — 2,400% year-over-year growth — and no existing phone system detects it. Vicall gives you a new managed service to offer: a secure VOIP line with built-in AI protection. It's another layer of security, another revenue stream, and another reason clients stay with you. Deploys cleanly alongside existing infrastructure.
Callback verification fails when the attacker has spoofed the caller's number — your callback reaches the attacker. Dual authorization can be socially engineered. Both happen after the employee has already been convinced by the voice. Vicall operates during the live call — detecting synthetic audio before the employee acts on any instruction. It's a fundamentally different layer that works where process-based controls break down.
