How to Spot a Fake Voice Call

It is now possible for scammers to create a realistic copy of someone's voice using just a few seconds of audio. They often get this from videos posted on social media.

They use this fake voice to call relatives with a made-up emergency, hoping to trick you into sending money. It's a new version of an old trick, but the technology makes it feel more real. The same AI is also used to create fake photos and videos. our guide to spotting deepfakes explains what to look out for there.

How the scam usually works

The most common version is the 'grandparent scam'. You get a call that sounds like a grandchild or other relative. They'll sound distressed and say they need money right away for a crisis, like a car crash or a lost wallet. They will often ask you to keep it a secret.

This is all designed to create panic and stop you from thinking clearly. The secrecy is to stop you from checking with anyone else.

Signs of a scam call

Even a good fake voice isn't perfect. Here are some things to look out for.

• A strong sense of urgency. Scammers will pressure you to act immediately.
• A request for secrecy. They might say "please don't tell Mum and Dad."
• An unusual payment method. They may ask for gift cards or a bank transfer to an account you don't recognise. These are almost always scams.
• They can't answer simple questions. Ask something a stranger couldn't guess from social media, like "What did you give me for my last birthday?".

What to do about it

There are a few simple steps that will stop most of these scams in their tracks.

1. Hang up. It might feel rude, but it's the safest response. If the emergency is real, they will understand.
2. Call them back on a known number. Use the number you already have saved in your phone for that person. This is the best way to confirm if they are really in trouble.
3. Talk to someone else. Before you do anything, tell a friend or another family member what has happened. A second opinion can help.
4. Report the call. You can report scam attempts to Action Fraud on 0300 123 2040 or through their website. This helps the police track the criminals.

Set up a family code word

One very good defence is to agree on a secret code word with your close family. It can be anything random, like "cabbage" or "biscuit".

If you get a suspicious call from someone claiming to be a relative, just ask them for the code word. A real family member will know it instantly.

Don't feel bad if you're targeted

These scams are run by professional criminals and are designed to be very convincing. There is no reason to feel embarrassed if you are taken in. The important thing is to report it and talk to your bank right away if you have lost any money.
