How to protect your family from AI voice-clone scam calls

AIooze Editorial

In one minute

  • You will be able to: spot a voice-clone “family emergency” call and stop it before any money moves.
  • You need: 10 minutes with the people you would most want to protect, and a phone.
  • How long it takes: one short family conversation, then a habit.

Why this is worth doing

A scammer no longer needs to sound “a bit off”. The FBI warns that criminals “generate short audio clips containing a loved one’s voice to impersonate a close relative” and then ask for urgent money or a ransom (FBI IC3 public service announcement). In October, INTERPOL launched a campaign on the same problem, warning that “AI is erasing the tell-tale signs of a scam” (AIooze brief).

So the old advice, “listen for something odd”, is no longer enough. The good news is that the defence does not depend on technology at all. It depends on a few habits that work whatever the voice sounds like.

The steps

  1. Agree a family safe word. Pick a word or short phrase that is easy to remember, not posted anywhere online, and not guessable from social media (so not a pet’s name). The FBI’s advice is to “create a secret word or phrase with your family to verify their identity” (FBI IC3). INTERPOL gives the same advice (INTERPOL).
  2. Agree the rule that goes with it. Anyone who calls asking for money in a hurry gets asked for the safe word. No word, no money, no exceptions, even if the voice is perfect.
  3. Make “hang up and call back” automatic. If a call is urgent and about money, end it and ring the person on the number you already have saved, not a number the caller gives you. The FBI advises verifying “the identity of the person calling you by hanging up the phone” and calling back. A familiar number on screen is not proof: the US regulator explains that spoofing is “when a caller deliberately falsifies the information transmitted to your caller ID display” (FCC).
  4. Slow down on purpose. Pressure and secrecy are the scam. INTERPOL’s slogan is “Wait. Validate. Don’t take the bait.” Tell family members it is always fine to say “I’ll call you straight back” and to talk it over with someone nearby first.
  5. Treat certain payment requests as a red flag. The US Federal Trade Commission says a real relative will “never pressure” you to “wire you money or buy you gift cards”, but a scammer might (FTC). The FBI adds cryptocurrency to that list.
  6. Shrink the voice sample scammers can find. The FBI suggests you “limit online content of your image or voice, make social media accounts private” where you can. You do not need to vanish from the internet; just check who can see videos where you or your children talk.
  7. Turn on two-step sign-in for email and bank accounts. INTERPOL recommends two-factor authentication on all online accounts, so a scammer who tricks someone into sharing details still cannot get in.

A worked example (illustrative)

Meera’s phone rings at 11pm. It is her son’s voice, crying: he has been in a car accident abroad, his phone is broken, and a “lawyer” needs money for bail tonight. Please do not tell Dad.

Because the family agreed a safe word last month, Meera asks for it. The voice says it is too upset to think. Meera says she will call him back, hangs up, and rings her son’s saved number. He answers from his flat, half asleep. The whole check took two minutes and cost nothing.

Notice what did the work: not spotting a fake voice, but a rule agreed in advance and a call-back to a number she already trusted.

Watch out for

  • Do not post the safe word in a family group chat that could be hacked; say it in person or on a call.
  • Older relatives are frequent targets. Practise the call-back once with them so it feels normal rather than rude.
  • Video can be faked too. The same check applies to an unexpected video call asking for money.
  • If money has already gone, contact your bank straight away (INTERPOL’s advice), then report it. In the US, report to the FBI at ic3.gov or the FTC at reportfraud.ftc.gov. In England, Wales and Northern Ireland, report to Report Fraud at reportfraud.police.uk or on 0300 123 2040; it replaced Action Fraud in December 2025 (City of London Police). In Scotland, call Police Scotland on 101. Elsewhere, contact your local police or your national fraud reporting service.
