Voice-clone and 'family emergency' scams: how they work, and the safe word that beats them

The phone rings and the voice is your grandson’s. He has crashed the car, he is in a police station, and he needs bail money within the hour. Then a second voice comes on the line, calm and official, to explain where to send it. “Please don’t tell Mum.”

This is the family emergency scam, sometimes called the grandparent scam. It is old. What has changed is the voice.

How the call works

The US Federal Trade Commission (FTC) describes the pattern. The caller poses as a family member or close friend who needs money urgently, or as an “authority figure” working with them: a fake lawyer, police officer or doctor. You are told it is urgent, and often that you must keep it secret. AARP describes one man who was told he had two hours to wire $9,000 for bail, and adds that the scammer may even send someone to pick up cash from you.

The new ingredient is voice cloning: software that copies how a person sounds. The FTC says all a scammer needs is “a short audio clip” of your relative’s voice, which could come from content posted online, and a voice-cloning program. It gives no figure for how short. Starling Bank, in the UK, said in 2024 that as little as three seconds can be enough.

The FBI’s Internet Crime Complaint Center (IC3) put this in a public warning in December 2024: criminals generate short audio clips of a loved one’s voice “to impersonate a close relative in a crisis situation”.

So “I would know his voice anywhere” no longer holds. The defences, happily, never depended on your ear.

Defence one: hang up and ring them back

This is the one that matters most. The FTC: hang up, or say you will call right back, then use “a phone number you know is right” to reach the family member. The US Federal Communications Commission (FCC) says to reach the person directly before sending any money. Take Five to Stop Fraud, a UK campaign, says to speak to them directly first.

Ring the number already saved in your phone, not one the caller gives you. If they do not answer, ring their parent, partner or flatmate. The FTC is explicit that you should do this “even if the caller said to keep it a secret”.

A real emergency survives a three-minute delay. A scam does not.

Defence two: a family safe word

The FBI’s first tip is to “create a secret word or phrase with your family to verify their identity”. AARP’s guide gives the same advice, and Starling’s Safe Phrases campaign, launched in support of the UK government’s Stop! Think Fraud campaign, is built on it. AARP also suggests an alternative: a family story only your relatives would know.

Some practical points of our own on choosing one:

• Make it unguessable from your online life. Not a pet’s name, a street, a football team or anything that has appeared on Facebook.
• Make it easy to say under stress. Two unrelated words work well.
• Agree it in person or on a call you made yourself. Starling’s advice is never to share it digitally, so no texts, emails or family group chats.

If a caller cannot produce the word, you have your answer. If they can, still ring back.

Defences three and four: how they want paying, and the secret

The FTC lists the payment routes these callers insist on: wire transfers, cryptocurrency, payment apps and gift cards. AARP adds one more: someone sent to pick up cash from you.

And nobody genuine needs you to keep it from the rest of the family. The request for secrecy is the scam protecting itself.

Being a harder target, without retreating

There is no need to stop posting holiday videos or to dread the phone. A few adjustments are enough.

The FBI suggests, “if possible”, limiting online content of your image or voice, making social media accounts private, and limiting followers to people you know. In practice that means checking who can see videos in which you or your family speak.

The FCC’s advice on unknown numbers is blunt: “Don’t answer calls from unknown numbers.” Our own addition: let them go to voicemail, and ring back the ones that leave a message you recognise.

One newer route to your voice is the fake survey. In February 2026 National Trading Standards, the UK body that tackles scams, warned that criminals are ringing people with bogus “lifestyle surveys” to draw out personal, health and financial details, then using AI to clone the voice they have recorded and set up direct debits (automatic bank payments) with it. Victims often do not notice the money leaving. Nobody is obliged to answer a survey from a caller they were not expecting: decline and hang up. “Genuine callers won’t mind,” Lisa Webb of Which?, the UK consumer group, told the Press Association. Then read your bank statement each month and query any direct debit you do not recognise, using the number on your card.

If it has already happened

It happens to careful, clever people. Act quickly and without embarrassment.

Ring your bank at once. In the UK, dial 159, which Stop Scams UK says connects customers of more than 99% of UK current accounts directly to their bank. In the US, the FTC says to tell your bank or card issuer straight away, using the number on the back of your card, and ask them to reverse the payment or refund your money.

Then report it.

• UK: Report Fraud, the City of London Police service that replaced Action Fraud in December 2025, at reportfraud.police.uk or on 0300 123 2040 (England, Wales and Northern Ireland). In Scotland, call Police Scotland on 101.
• US: the FTC at ReportFraud.ftc.gov, the FBI at ic3.gov, and for a calm voice the free AARP Fraud Watch Network Helpline on 877-908-3360, Monday to Friday, 8am to 8pm Eastern.

This week: the two-minute conversation

Next time you see or ring your family, try something like this:

“There are scam calls now that can copy a voice. If any of us ever rings another asking for money in a hurry, we ask for the family word. Ours is ____. We never text it or write it online. And if you ring me in real trouble and I hang up and call you straight back, that isn’t doubt. That’s the plan.”

Then save their current numbers, and carry on answering the phone to the people you love.
