AI Voice Clone Scams Targeting Families: A Defense Checklist

A familiar voice is no longer proof it is really them

You answer the phone and hear your daughter, your father, or your grandson — panicked, talking fast, asking you to send money this minute. Everything in you wants to help. That reflex is the whole target.

The FBI warns that criminals use generative artificial intelligence to commit fraud on a larger scale and to make their schemes more believable, and that they can use AI-generated audio to impersonate personal relations in order to elicit payments. The same warning notes that generative AI reduces the time and effort needed to deceive a target, and can even correct the small human slips that might otherwise give a scam away. The practical takeaway is blunt: a caller who sounds exactly like your relative is no longer proof that it is your relative.

Because AI-generated content can be hard to identify, you cannot count on catching the fake by listening harder during the call. So this checklist does not ask you to judge the voice. It asks you to move the decision off the call and onto a channel you control.

The checklist for an urgent call asking for money or silence

Run these steps in order. None of them depend on whether the voice sounds real.

1. Slow it down. Do not let a deadline prevent verification. If the caller insists you act within a minute or stay on the line, stop before making any payment.

2. Hang up and call back on a number you already have. Do not dial a number the caller gives you, and do not trust the number shown on your screen. Open your own contacts, call the person directly, and confirm. If they do not pick up, reach them another way or check with another relative before you do anything.

3. Switch to a second channel. The phone call is one channel. Send a text, start a video call, or ask in the family group chat. Ask about a shared detail that is not posted anywhere online.

4. Set a family code word before you ever need it. Choose a private phrase your household keeps off social media. When a call feels urgent and off, ask for it, then still call back on a number you trust. A correct answer does not replace independent verification.

5. Do not send money, gift cards, or cryptocurrency because of a phone call. Treat any demand to move assets fast, to someone you have reached only by phone, as a reason to stop rather than to hurry.

6. Keep the evidence and report it. Save the voicemail, write down the number and the time, and hold on to any payment details. The FBI directs victims of financial fraud to report through IC3.

What a deepfake detector can and cannot do here

If the suspicious audio was recorded — a saved voicemail, a forwarded clip, an attached video — you can check it. DeepFakeCheck analyzes audio, image, video, and text and returns a probabilistic risk signal. Initial use does not require an account, and there is a limited free-use allowance.

Read that result carefully. A detector gives a probability, not a ruling. Automated detectors produce false positives, where genuine media gets flagged as fake, and false negatives, where a synthetic clip slips through. A score cannot on its own prove that a call was real or that it was a scam. Use it as one more input alongside the steps above, never as a substitute for calling the person back on a number you trust.

For this check, save a voicemail or clip and upload that file separately. Hang up and verify through a channel you control before waiting for any detector result; the checklist leans on process instead of on catching the fake by ear.

If you have already sent money

Move fast, in this order.

• Stop. Send nothing more, even if you are told the first payment failed.
• Call the fraud line of your bank or payment provider right away and tell them a payment may be fraudulent.
• Report it. File with the FBI Internet Crime Complaint Center at www.ic3.gov, and include who contacted you, what they asked for, and the payment details you have.
• Tell your family what happened. Share which number and payment request were involved so everyone can verify any related contact independently.

The FBI warns that generative AI can make fraud schemes more believable. The reliable defense is not a sharper ear. It is a fixed habit: slow down, hang up, verify on your own channel, and never let a phone call be the final word on where your money goes.
