Could a scammer really sound exactly like your son or daughter on the phone?

What is a voice cloning scam?

AI voice cloning is technology that can copy the way a person speaks — capturing their tone, accent, rhythm, and speech patterns — and then generate a fake recording that says anything the scammer wants. Until recently, creating a convincing fake voice required hours of recordings and technical expertise. Now, cheap or free apps can produce a convincing clone from as little as three seconds of audio.

Fraudsters use this technology to call you and pretend to be someone you love. A typical scenario: you receive a call that sounds exactly like your daughter saying she has been in an accident, lost her wallet, and urgently needs you to transfer money or buy gift cards. The voice is hers. The accent, the way she says “Mum” or “Dad” — it all sounds right. But it is not her.

How do scammers get hold of your family’s voice?

Three seconds of audio is all that is needed. Scammers harvest voice clips from places you might not think twice about:

• Social media videos on Facebook, TikTok, Instagram, or YouTube
• Voicemail greetings (“Hi, I can’t take your call right now…”)
• Voice messages sent in WhatsApp group chats
• Interview clips, podcast appearances, or videos posted by employers

If anyone in your family has ever posted a video online, their voice is potentially available to a scammer. This is not a reason to panic — it is a reason to prepare. One simple precaution is all you need.

What does a voice cloning scam call actually sound like?

Convincing — that is the honest answer. The cloned voice will have your family member’s accent and speech patterns. The call may also appear to come from a number that looks like your contact’s, because scammers can spoof caller ID to show any number they choose. Two fake signals combining — the right-sounding voice and the right-looking number — can make even a sceptical person hesitate.

Common urgency scripts used in voice cloning calls include:

• “I’ve been in an accident and I need money straight away”
• “I’ve been arrested abroad — please don’t tell anyone, just send the bail money”
• “My phone is broken, this is a friend’s number — please transfer the money now”
• “The hospital needs a payment before they will treat me”

It is worth remembering: the NHS never charges for emergency treatment, and no genuine emergency — legal, medical, or otherwise — will ever ask you to pay by gift card. These are universal warning signs of a scam, regardless of how convincing the voice sounds.

How does a family safe word protect you — and how do you set one up?

The most effective defence against voice cloning scams is also the simplest: agree a secret code word with your closest family members. Choose something personal and easy to remember — a favourite film, a childhood pet’s name, a made-up word — but nothing that a stranger could guess from your social media.

If you receive a call that sounds like a family member in distress, stay calm and ask for the safe word before you do anything else. A cloned voice cannot answer a question it was never trained on. If the caller cannot give the correct word, hang up immediately and call your family member back on the number you have stored in your own contacts.

Security experts and police forces across the UK — including the Royal Borough of Greenwich and Northumberland County Council, both of which have issued public warnings about these calls — recommend the safe word as the single most practical step you can take. It costs nothing and takes five minutes to set up. Do it this week.

What other steps can you take to stay safe?

• Register with the Telephone Preference Service (TPS): Free to join at tpsonline.org.uk — reduces cold calls, though it does not block all scam numbers.
• Never pay by gift card: No real emergency, court, HMRC debt, or family crisis will ever ask you to pay with iTunes, Amazon, or Google Play gift cards. Always a scam.
• Hang up and call back independently: If a call makes you anxious, hang up. Wait a few minutes, then call the person or organisation directly using a number you find yourself — not one given to you on the call.
• Talk to family about social media privacy: Ask your children or grandchildren to set their accounts to private and be cautious about public voice or video content.
• Trust your instincts: Scammers rely on urgency and panic to override your better judgement. If something feels wrong, it probably is. Pausing to check is always the right move.

What should you do if you think you have received a voice cloning scam call?

Whether or not you sent any money, it is worth reporting what happened. Doing so helps protect other people and is nothing to be ashamed of — these scams are highly sophisticated and catch people of every age and background.

• Report Fraud: Call 0300 123 2040 or visit reportfraud.police.uk
• Action Fraud: The UK’s national fraud reporting centre — actionfraud.police.uk
• Contact your bank immediately if you transferred money. Under APP fraud reimbursement rules introduced in 2024, UK banks are required to refund most victims of authorised push payment scams — so act quickly and there is a good chance you can recover your money.
