The risk

Where voice cloning shows up

Cloned executives by phone

A few seconds of public audio is enough to clone a voice convincing enough to move a wire or force an exception.

Spoofed vendor and candidate calls

A cloned vendor confirming new banking details, or an altered candidate voice on a screening call.

Synthetic drift under pressure

Synthetic audio that holds up for a moment but drifts as the script pushes toward the ask.

The attack playbook

How a voice-cloning attack unfolds

These attacks move through a recognizable sequence. Diopter scores that sequence while the call is still in progress.

01
Authority

A familiar voice calls

An executive, a vendor contact, or a candidate, recognizable enough that the request feels routine.

02
Urgency

Urgency arrives early

A closing window, an overdue invoice, or a competing offer compresses the time to verify.

03
Isolation

The call moves off-channel

The conversation shifts to a private line or a follow-up that keeps others out of it.

04
Escalation

The asks escalate

A small confirmation becomes a larger request as the call builds on each prior yes.

05
The ask

The action is taken

A wire, a banking change, or an offer is acted on while the voice is still trusted.

How Diopter helps

What Diopter looks for

01

Synthetic audio scoring

Continuous scoring of voice for cloning and text-to-speech artifacts throughout the call.

02

Acoustic consistency scoring

Diopter tracks spectral patterns and prosodic signatures across the call, flagging drift and inconsistencies that indicate cloned or synthetic audio.

03

Mid-call drift detection

Diopter tracks acoustic patterns for synthetic indicators that emerge and accumulate as the call progresses.

Where it shows up

One capability across every call where trust moves.

The same detection applies wherever an attacker uses a call to push money, access, or a hire through.

Hiring & staffing

Flag altered or cloned voices on phone and video screening calls.

Financial wire fraud

Catch a cloned executive voice authorizing a treasury or closing wire.

Vendor payments

Expose a spoofed vendor voice confirming a new banking detail.

Executive impersonation

Surface a cloned executive voicemail or call pushing an exception.

Verdict
Hold for verification

A synthetic-voice verdict reaches your team while the call is live, with a recommended next step.

Why Diopter

Most tools check one clip. Diopter reads the whole call.

Point-in-time detectors answer a single question: is this video or voice fake? A good clone passes that test. Diopter scores the whole conversation, the authority claims, the manufactured urgency, the push to go off-channel, and the escalating ask, then raises a verdict on the pattern a single frame cannot show.

A cloned voice passes a single listen. The script it runs, urgency, isolation, and the ask, gives it away across the call.

Deployment & trust

Light to deploy, clear about what runs where.

Pilot in days, roll wider through MDM, and keep sensitive call media inside your perimeter.

Deployment & trust
  • On-prem and hybrid deployments supported
  • No caller-side install
  • Bot or bot-free capture
  • Configurable retention, including ZDR
  • MDM rollout (Intune, Jamf)
  • SOC 2 Type II in progress
