AI Voice Clone Scams: How to Spot Them

Your phone rings. It is your grandchild's voice — distressed, in trouble, needing money right now. It sounds exactly like them. It is not them. AI voice cloning has made the grandparent scam near-perfect, and this guide explains how it works and how to stop it.

The scam, step by step

The scammer starts by finding a few seconds of the victim's voice: a voicemail greeting, a social media video, a clip from a call. AI voice software then learns the sound of that voice and can make it say anything — a car crash, an arrest, a hospital bill, a desperate need for money. The scammer calls an older relative, usually a grandparent, and plays the part: crying, panicked, begging for help, and — critically — begging for secrecy. "Don't tell Mum and Dad, they'll be angry." The money is requested by wire transfer, gift cards or cryptocurrency, because those cannot easily be reversed. The whole call takes minutes. By the time the family checks, the money is gone.

There is some evidence that such scams are growing in volume, and this is the highest-harm emerging scam variant in our research — because it defeats the one defence older people have always relied on: recognising a loved one's voice. This page is general education; exact figures on how common these scams are vary by country and by reporting, and we do not publish a number we could not verify. Last checked: 14 November 2026.

Why you cannot just "listen harder"

The honest truth is that a good voice clone is hard to tell from the real thing by ear — especially on a phone call, where the audio is compressed, the caller is panicking, and you are frightened. There are sometimes clues: odd pauses, flat emotion in the wrong places, a voice that cannot answer a question it should know easily, a caller who refuses to be put on speakerphone or switch to video. But none of those is reliable, and a skilled scammer steers around them. If your defence is "I would know my grandchild's voice," this scam is designed to beat it.

The defence that actually works

The defence is not better listening. It is verifying through a route the scammer does not control.

  1. Agree a family code word now. Pick a secret word or phrase your whole family knows — something a stranger could not guess. If someone calls claiming to be family and in trouble, ask for the code word first. If they do not know it, hang up. Write it down somewhere safe, and change it yearly.
  2. Hang up and call back on a number you already know. Never use a number the caller gives you. Call the person's own phone, or another family member, and ask if they are safe. The three minutes this takes are the whole defence.
  3. Never pay because of one call. No emergency needs money in the next ten minutes by gift card or wire transfer. If it is a real emergency, the hospital or the police will not ask you to pay by gift card.
  4. Refuse secrecy. A real family member in trouble does not need you to keep it from the rest of the family. "Don't tell anyone" is a scam sentence.
  5. Ask a question only the real person would know — not their birthday, which is public, but something private and specific, like the name of a childhood pet or a family joke.

Reducing the raw material

A voice clone needs a voice sample. You cannot remove your voice from the world, but you can shrink the supply:

  • Keep voicemail greetings short, and do not record your full name in them.
  • Limit public videos of family members, especially children — videos are the richest source of voice samples. See our sharenting guide for the full picture.
  • Check who can see family videos on social media, and tighten the audience.

If it happened to your family

  1. Contact the bank immediately if money was sent — it may be able to stop or reverse the payment.
  2. Report it to your national fraud reporting service — in the US, the FTC at ReportFraud.ftc.gov — and your local police.
  3. Tell the rest of the family, so the code word can be changed and everyone is alert.
  4. Be kind. The person who was tricked is a victim of a professional crime, not a fool — the same scam has caught careful people everywhere, and our seniors' safety guide explains why.

Fake video calls are next

Voice cloning is already here; face cloning is close behind. A video call that appears to show your grandchild's face, speaking in their voice, is becoming possible — and the same defences apply, because the defence is not about spotting the fake, it is about verifying through another route. If a video call arrives from an unknown number, or from a familiar person in an emergency asking for money, hang up and call back on a number you already know. Ask for the family code word. Ask a question only the real person would know. A live video call that cannot answer a simple personal question, or that refuses to switch to a different channel, is a warning sign. The rule is unchanged since the days of the letter scam: verify through a route you chose, never through the message — whatever the technology.

Set the code word this week. It takes two minutes, costs nothing, and it is the one defence a voice clone cannot beat — because the scammer cannot know a word the family never said aloud in public. Put it in your family internet safety plan .

Frequently asked questions

What is an AI voice clone scam?

A scam where a criminal uses AI software to copy someone’s voice — often a grandchild — from a few seconds of audio found online, then calls an older relative pretending to be that person in trouble, asking for money urgently. The voice can sound exactly right.

How does voice cloning work?

AI voice tools learn the sound of a voice from a short recording — a voicemail greeting, a social media video, even a few seconds from a call — and can then make that voice say anything. The technology is cheap, widely available, and improving fast.

How can I tell a cloned voice from a real one?

Usually you cannot reliably tell by ear alone — that is what makes this scam dangerous. The defence is not listening harder; it is verifying through another route: hang up, call the person on a number you already know, and use a family code word agreed in advance.

What is a family code word?

A secret word or phrase your family agrees in advance, which a real family member would know and a scammer would not. If someone calls claiming to be family and in trouble, ask for the code word. If they do not know it, hang up.

Should I remove my voicemail greeting?

You do not need to remove it, but do not record a long personal greeting with your full name and details. Short greetings give scammers less material. More important: limit public videos of family members, and never post a child’s voice or face publicly without thinking.
