AI Voice and Video Scams: They Sound Exactly Like Someone You Trust

I had a customer come in last month, visibly shaken. She'd had a phone call from her son asking her to transfer money because he'd been in a car accident. She said it sounded exactly like him. The panic in his voice, the way he said "Mum." She was seconds away from sending the money when her actual son walked through the front door.

It wasn't him on the phone. It was an AI clone of his voice.

This is not some futuristic threat. It is happening right now, in the UK, to ordinary people. Voice cloning scam attempts went up over 400% in 2025, and UK fraud losses from AI-powered scams hit around £800 million the same year. The numbers for 2026 are expected to be worse.

I'm writing this because it genuinely worries me. Most of my customers are not tech people. They're parents, grandparents, small business owners. They're exactly the people these scams target.

How voice cloning actually works

The short version: someone needs about three seconds of your voice. That's it. Three seconds, and a free AI tool can build a voice model that sounds like you.

Where do they get those three seconds? Anywhere. A Facebook video, an Instagram reel, a voicemail greeting, a TikTok clip, a work conference recording on YouTube. If your voice is anywhere on the internet, it can be cloned.

The tools to do this are freely available. Some have safeguards built in. Most don't. Consumer Reports tested six popular voice cloning tools in 2025 and found that four of them had no meaningful protections against misuse at all.

The cloned voice can then be used in real time. The scammer talks into a microphone, and what comes out the other end is your daughter's voice, or your boss's, or your bank's fraud team.

What these scams look like

The most common version in the UK right now is the family emergency call. Late at night or early morning, when you're groggy and not thinking straight. The caller sounds like your child, your partner, your sibling. They say they've been arrested, or in an accident, or mugged abroad. They need money wired immediately. Don't tell anyone else.

Pressure and urgency. That's always the formula.

But it goes further than phone calls. In early 2024, an employee at the engineering firm Arup joined what he thought was a routine video call with his company's CFO and several colleagues. Every person on that call was a deepfake, generated in real time. He transferred $25.6 million across 15 transactions in a single day before anyone realised.

Celebrity investment scams are another big one. Deepfake videos of Martin Lewis, Holly Willoughby, and Jeremy Clarkson have been used to push fake investment platforms. One campaign using doctored footage of public figures conned 6,179 victims in the UK and Canada out of £27 million.

Banks are seeing it too. Scammers clone a customer's voice to pass phone verification. They clone a manager's voice to authorise transfers. Financial institutions reported $1.8 billion in losses from AI voice fraud globally in 2025.

Why it works so well

Because we trust voices.

If you get a text from an unknown number saying "Mum, I've lost my phone," most people are suspicious now. We've been trained to spot that one. But a phone call where the voice is right? Where they sound upset, afraid, in pain? That bypasses every rational defence you have.

Late last year, researchers confirmed that cloned voices have crossed what they call the "indistinguishable threshold." Human listeners cannot reliably tell the difference between a cloned voice and the real person. You cannot listen your way out of this. Your ears are not good enough, and neither are mine.

The scammers also know that shame keeps people quiet. Only about 15% of victims report these crimes. People feel stupid for falling for it, especially when they find out the voice wasn't real. So the actual losses are far higher than the official numbers.

What to actually do about it

You cannot detect a cloned voice by listening carefully. Forget that. Instead, you need systems in place before the call happens.

Set up a family safe word

Agree on a word or phrase with your family that nobody else would know. Something that wouldn't come up in normal conversation: a childhood nickname, an inside joke, a made-up word. If someone rings claiming to be your daughter and asking for money, ask for the safe word. If they can't give it, hang up.

This is the single most effective thing you can do. It costs nothing, it takes two minutes to set up, and it works against every type of voice impersonation.

Tell your parents about this. Tell your grandparents. Do it this week.

Always call back

If someone phones you with an urgent request for money or personal information, hang up and call them back on the number you have saved for them. Not the number they called from. Not a number they give you during the call. The number already in your phone.

A real emergency will still be an emergency in two minutes. A scam falls apart the moment you hang up and dial the real person.

Know about 159

If you get a call claiming to be from your bank, hang up and dial 159. This is the UK's official banking safety number, run by Stop Scams UK. It works like 111 for the NHS or 101 for the police. You select your bank from a menu and it connects you directly to their fraud team. Over a million calls have been made to 159 since it launched in 2021.

159 covers more than 99% of UK retail bank accounts. It cannot be spoofed, and it will never call you.

Lock down your social media

If your Facebook profile is public and you've posted videos of yourself talking, you've given scammers everything they need to clone your voice. Set your profile to Friends Only. Remove public videos if you can, or at least restrict who can see them.

The same goes for voicemail greetings. A standard "Hi, you've reached Sarah, leave a message" is enough audio to build a voice model. Consider using a generic automated greeting instead of recording your own voice.

Be sceptical of video calls too

Real-time face-swapping now runs on consumer hardware. It doesn't look perfect on a big screen, but on a small Teams or Zoom tile at typical resolution, it passes casual inspection. If you get an unexpected video call from a colleague asking you to do something unusual (transfer funds, share credentials, approve access), verify it through a separate channel first.

If you think you've been targeted

If you sent money, contact your bank immediately. Under the UK's Authorised Push Payment (APP) fraud rules, you may be eligible for reimbursement, but time matters. The sooner you report it, the better the chance of recovering funds.

Report it to Action Fraud on 0300 123 2040, or online at actionfraud.police.uk. Even if you didn't lose money, reporting it helps police track the patterns.

And do not feel embarrassed. These are not obvious scams. A cloned voice that sounds exactly like your child calling in distress is not something you should feel stupid for believing. The technology is designed to fool you, and it is very good at it.

Where this is heading

It is going to get worse before it gets better. The tools are getting cheaper and easier to use. Cross-channel AI fraud (combining fake voice, video, and text messages in a single attack) is expected to make up more than 60% of fraud attempts by 2027.

The UK government's Fraud Strategy 2026-2029 flags AI as an emerging challenge, but regulation moves slowly and the technology moves fast. Right now, your best defence is not a piece of software. It is a habit. The habit of verifying before acting, every time, even when the voice on the other end of the phone sounds exactly like someone you love.
