How to spot AI scam calls and voice clones, and set up a family safe word

Updated October 17, 2026 · About 6 minutes to read · Free guide

Imagine your phone rings. It's your grandson, and he sounds frightened. He's been in a car accident, or he's been arrested, and he needs money right away. "Please don't tell Mom," he says.

It sounds exactly like him. But it might not be him at all.

Scammers can now use AI to copy a person's voice from a short recording, sometimes just a few seconds taken from a video posted online. This guide explains how these calls work, the warning signs to listen for, and one simple family habit that stops them cold.

How voice-clone scams work

The trick is old. The technology is new.

For years, criminals have run the "grandparent scam": they call an older person, pretend to be a grandchild in trouble, and ask for money. In the past, the voice was a guess. Now, AI tools can make a fake voice that sounds very much like a real person.

Here's the usual pattern:

The scammer finds a clip of someone's voice, often from social media.
They use an AI tool to make that voice say whatever they type.
They call a relative, usually a parent or grandparent, with an emergency story.
Often a second person comes on the line, pretending to be a lawyer, police officer or doctor, to make it feel official.
They ask for money fast, in a way that's hard to get back: a wire transfer, gift cards, cryptocurrency, a payment app, or cash handed to a "courier" who comes to your door.

The same trick is used with fake calls from "your bank," "Medicare," "the IRS," or a "tech support" company. The caller ID can be faked too, so the screen might show a real bank's name.

Warning signs to listen for

A call is very likely a scam if it has several of these:

Urgency. "You have to act right now." Scammers don't want you to have time to think.
Secrecy. "Don't tell anyone." "Don't call Mom." Real emergencies don't need secrets.
Unusual payment. Gift cards, wire transfers, cryptocurrency, Bitcoin ATMs, or a courier picking up cash. No real court, police department or government office asks for these.
Strong emotion. Crying, panic, fear. Strong feelings make all of us think less clearly. That's the point.
A bad line. "The connection is bad, I can't talk long." This hides the small oddities of a fake voice.
Small things feel off. The person won't answer a simple personal question, or the call came from an unknown number.

Remember: you can sound exactly like yourself and still be fooled. These scams catch smart, careful people every day. There is no shame in it.

The family safe word: your best defense

A family safe word (also called a code word) is a word or short phrase that only your close family knows. If someone calls claiming to be a family member in trouble, you ask for the word. A scammer won't know it, no matter how real the voice sounds.

How to set one up

Pick something memorable but not guessable. Avoid pet names, street names, birthdays or anything posted online. Something silly works well: "purple pancakes" or "Uncle Frank's canoe."
Share it in person or on a phone call you started. Don't post it, text it to a group, or write it on social media.
Tell everyone who might call in an emergency: children, grandchildren, and anyone who helps care for you.
Practice once. Agree on the rule: "If you're ever in trouble and call me for money, I'll ask for the word."
Write it down somewhere private at home, not in your phone's notes or your wallet.

If the caller can't give the word, or gets upset when you ask, hang up.

What to do if you get a suspicious call

Stay calm and slow down. It is always OK to say, "I'll call you right back."
Ask for the safe word, or ask a question only the real person would know.
Hang up and call back on a number you already have saved, not a number the caller gives you.
Check with another family member. Call your grandson's parent, or text him directly.
Never pay with gift cards, wire transfers, cryptocurrency or cash handed to a stranger.
Don't give out information. Don't confirm your address, bank or account numbers.

Using AI to check a message

AI can also help you here. If you get a suspicious text or email, copy the words (with your name and any numbers removed) and paste them into ChatGPT or Gemini with this prompt:

I received this message. Does it show signs of a scam? Please list the warning signs in plain English, and tell me what a safe next step would be. Here is the message: [paste message]

It's a helpful second opinion, but your own judgment comes first. When in doubt, call the company using the number on your card or statement.

Protecting your own voice

You don't need to stop sharing family videos, but a few habits help:

Set your social media accounts to private, so only friends and family see your posts and videos.
Be cautious with calls from unknown numbers. Let them go to voicemail. A real caller will leave a message.
Ask your bank whether it offers extra protection, such as a verbal password on your account.

If you've already sent money

Act quickly. Speed matters.

Call your bank or card company first, using the number on the back of your card. Ask them to stop or reverse the payment.
If you paid with a gift card, call the gift card company using the number on the back of the card, and keep the card and receipt.
Report it to the Federal Trade Commission at ReportFraud.ftc.gov, and to the FBI at ic3.gov.
Call the National Elder Fraud Hotline at 1-833-FRAUD-11 (1-833-372-8311). It's free and run by the U.S. Department of Justice, Monday to Friday, 10 a.m. to 6 p.m. Eastern Time.
AARP's Fraud Watch Network Helpline, 877-908-3360, is also free and open to everyone, not just AARP members. Trained volunteers can help you work out next steps, without judgment.

Watch out for a second scam: people who call afterward promising to "recover" your lost money for a fee. That is almost always another scam.
