01 · Banking and payments

Pay, transfer, change the payee. By voice.

Voice payments and account changes are where a cloned voice or a replayed recording pays off fastest. Verbrisk ties each instruction to the enrolled customer, live, in the same session that said the wake word.

Main risks: Voice clones, replayed approvals, a second person issuing the instruction.
Checks that carry the weight: Speaker match, liveness, same speaker; signal integrity in the app at full rate.
Typical policy: Transfers and payee changes: block on any hostile check, confirm out of band when unverified.

02 · Contact centres and telco

Voice agents on the phone line.

Phone audio arrives at 8 to 16 kHz, so no ultrasonic carrier survives to be detected. Verbrisk says so in every decision and relies on who is speaking and what they are asking for.

Main risks: Synthetic callers, social engineering scripts, spoken prompt injection aimed at the agent.
Checks that carry the weight: Speaker match against the account holder, liveness, content safety, transcript consistency.
Typical policy: Signal check "could not run" is treated as unverified: sensitive actions are confirmed, never silently allowed.

03 · Healthcare

Records and prescriptions behind a request.

A voice agent that books, refills or reads out results is handling protected information. Verbrisk makes sure the person asking is the patient or an enrolled carer, and keeps the evidence.

Main risks: Someone else in the room, replayed voices, requests designed to extract records.
Checks that carry the weight: Same speaker, speaker match, content safety for exfiltration patterns.
Typical policy: Reading results aloud requires a trusted speaker; refills are confirmed on the patient's own device.

04 · Automotive

Hands-free, not hands-off.

In-car assistants navigate, call and pay while the driver keeps their eyes on the road. A passenger, the radio or a device near the car should not be able to give the same orders.

Main risks: Passengers and media audio, inaudible injection from outside the cabin.
Checks that carry the weight: Signal integrity at the head unit's full sample rate, speaker match for the driver profile.
Typical policy: Navigation changes confirmed on screen; payments require the driver's voice.

05 · Smart home and devices

Locks, alarms and purchases.

Hubs, earbuds and glasses keep the full-rate audio that ultrasonic detection needs, which makes the device the best place to run the signal check. Verbrisk is small enough to run there.

Main risks: Ultrasonic injection, television and media, visitors.
Checks that carry the weight: Signal integrity on device, the room-consistency check, speaker match for the household.
Typical policy: Unlock and disarm: block on any hostile signal; purchases confirmed in the app.
