How to Protect Your Family from AI Voice Clone Scams

The phone rings. It is your son, or your daughter, or your gran. They sound scared. They say they are in trouble and need money sent straight away, and please don't tell anyone. Every instinct tells you to help. That is exactly what the criminals are counting on.

Voice cloning scams use software to copy a real person's voice, often from a few seconds of audio taken from a social media video. I run Kells Security Solutions to explain scams like this in plain English, and this one worries me more than most, because it goes after love, not greed. The good news is that there is a simple, free defence, and it takes about five minutes to set up.

How Voice Clone Scams Work

The scammer finds a voice online, usually a clip from Facebook, Instagram or TikTok. They feed it into software that can copy the sound and speech patterns. Then they ring a relative, often an older one, pretending to be the person in the clip.

The story is nearly always the same. An accident, an arrest, a lost phone, a stranded trip abroad. There is always a deadline, always secrecy, and always a request for a fast payment by bank transfer, gift cards or crypto. Not every call uses a cloned voice. Some are just a crying stranger saying "it's me". But the technology has made the fake far more convincing, so I no longer tell people to trust their ears.

If you want the wider picture of how scammers use what you post, I have covered it in the social media habits that quietly put people at risk.

The Family Safe Word

This is the single best defence I know. Agree one word or short phrase with your close family that only you know. If anyone rings in an emergency asking for money or help, you ask for the safe word. No word, no help, whoever it sounds like.

A few rules make it work. Pick something that cannot be guessed from social media, so not a pet's name or a street. Make it unusual and easy to say, like "purple lighthouse". Never post it, text it or put it in a group chat. Tell everyone who might be targeted, especially grandparents, and practise it once so it feels normal rather than awkward.

What To Do When the Call Comes

Even without a safe word, you can beat this scam if you slow it down. Scammers rely on panic, so your job is to break the spell.

Hang up. Then ring the person back on the number you already have for them, not one the caller gives you. If they don't answer, try someone else who would know where they are, such as a partner, a friend or their workplace. Ask a question only the real person could answer, like the name of a childhood pet or what you had for dinner on Sunday. Be very suspicious of anyone who begs you not to tell other family members.

Never send money, buy gift cards or move cash in response to an urgent call, however real it sounds. A genuine family member in trouble will still be there in ten minutes when you ring back.

Making Yourself and Your Family Harder to Copy

You can't stop a voice being copied altogether, but you can make it harder. Set social media accounts to private where you can, and think before posting videos of yourself or your children talking. Check what your older relatives have posted too, because it is often their own grandchildren's clips that get taken.

Turn on two-step verification for your email and banking apps, so a scammer who does get information from a call can't walk straight into your accounts. I explain how in helping an older parent stay safe online, which is also worth reading if you are the family's unofficial IT support.

Veterans and serving personnel are targeted too, because our families are often posted about online. I write about this for CIVVY Magazine, the independent magazine written by veterans for veterans.

If You Think You Have Been Caught Out

Ring your bank straight away. You can reach most UK banks by dialling 159, the number set up by the banking industry for exactly this. The sooner they know, the better your chance of stopping the payment or getting the money back.

Then report it to Report Fraud, the service that replaced Action Fraud, or ring Police Scotland on 101 if you are in Scotland. The National Cyber Security Centre also has good advice on spotting and reporting scam calls. My Safety Toolkit pulls the main reporting links into one place, and I have set out the other options in where I actually report a scam.

Please don't feel embarrassed. These calls are designed by professionals to get past even careful people. Tell your family what happened so they are ready if the same number rings them.

Five Minutes Tonight

Pick your safe word. Tell your close family. Write it down somewhere private, not on your phone. That is the whole job, and it could save someone you love a great deal of money and heartache.

If you want the bigger picture on the cons most likely to catch people out, my book Spot the Scam explains ten of them in plain English. You can read more about me and why I do this, or get in touch if you have had a call you are not sure about and I will take a look.
