How do AI voice scams work, and how do you protect yourself?

In an AI voice scam, criminals clone someone's voice from a short clip, often taken from videos posted online, then call or send voice messages pretending to be a relative in trouble who needs money fast. Don't trust the voice: hang up, call the person back on a number you know, and agree a family code word in advance.

β–Ά Try it

Why it matters

AI can copy a voice from a short recording, so a call can sound exactly like someone you love. You'll learn the pattern of these scams and two simple defences: call back and a code word.

In 6 minutes you'll be able to

  • Agree a family code word that you never post online.
  • Hang up and call back on a number you already know.
  • Urgency, secrecy, a new number and gift cards are the warning signs.

What you'll practise

  1. Voice message check

    These are transcripts of voice messages that sound just like Leo. For each one: okay or warning sign?

    Unknown number Β· Voice messages

    1. Tonight, 23:12
    2. πŸŽ™οΈ "Hey, it's me, Leo" (Okay)
      On its own, a hello is normal. But you can't judge a voice by how it sounds any more. Watch what comes next.
    3. πŸŽ™οΈ "I lost my phone, this is a friend's number" (Warning sign: New number)
      A new number stops you checking with the old one. It's the classic opening of impersonation scams.
    4. πŸŽ™οΈ "I'm in real trouble, I had a car accident" (Warning sign: Urgency)
      A sudden emergency creates panic, and panic stops you thinking. That's the point.
    5. πŸŽ™οΈ "Can't talk, the police are here, just listen" (Warning sign: Avoids a call)
      Scammers avoid live conversation, because questions would expose the fake voice.
    6. πŸŽ™οΈ "Please don't tell Mum, she'll freak out" (Warning sign: Secrecy)
      Secrecy stops you checking with anyone else. A real emergency doesn't need hiding from family.
    7. πŸŽ™οΈ "Send $800 in gift cards and text me the codes" (Warning sign: Odd payment)
      Gift cards, crypto and wire transfers are hard to reverse. That's why scammers ask for them.
    8. πŸŽ™οΈ "Love you, sorry about this" (Okay)
      Affection is normal, and that's exactly why this scam works. It doesn't make the caller real.

  2. Three calls

    Short scenes. What's the safe move?

    1. Your "mum" calls from an unknown number, crying, and asks for money right now.

      • Hang up and call Mum on the number you saved (Answer)
      • Send the money, it's definitely her voice

    2. Your family agreed a code word. The caller who sounds like your sister can't say it.

      • End the call and check with her directly (Answer)
      • Accept it, she must have forgotten under stress

    3. Your "boss" sends a voice note asking you to pay a new supplier today, quietly.

      • Confirm through a known channel before paying (Answer)
      • Pay it, the voice note sounds just like them

  3. Got a panicked call? Do this

    Put the safe steps in order.

    1. Stay calm and don't send money or codes
    2. Ask for your family code word
    3. Hang up and call the person on a number you know
    4. Check with another family member if you can't reach them
    5. Report the scam, even if you didn't pay

  4. Where to get help

    If a cloned voice already tricked you or someone you know, act fast. It's not your fault: these scams fool careful people.

    🏦 Call your bank now
    If you sent money or card details, call the number on the back of your card. The faster they know, the better the chance to stop the payment.
    πŸ“ž Warn the real person
    Call the person whose voice was copied on a number you already know, and warn your family about the scam.
    πŸ“ Report it
    Report the scam to the fraud reporting service below. Keep the number, the time and any messages as evidence.

Remember

A familiar voice isn't proof. Hang up, call back on a known number, and use a code word.

A familiar voice isn't proof. Hang up and call back.

Questions people ask

How much audio do scammers need to clone a voice?

Only a short clip, according to the FTC, for example from a video posted on social media. That's why a familiar voice on its own is no longer proof of who is calling.

What is a family safe word?

A word or phrase your family agrees in advance and never posts online. If a caller claiming to be family can't say it, hang up and check with that person directly.

How can I tell if a voice is AI-generated?

Often you can't by listening alone. Instead, check the situation: urgency, secrecy, a new number and unusual payment requests are the signs. Then call back on a number you know.

Where do I report a voice cloning scam?

In the US, report it to the FTC at ReportFraud.ftc.gov and the FBI's IC3. In the UK, report it to Report Fraud (reportfraud.police.uk), or to Police Scotland on 101 in Scotland. If you paid, contact your bank immediately.
