What is a voice cloning scam?
A voice cloning scam is a phone call or voice message where a fraudster uses AI to imitate the voice of someone you know. In March 2023, the US Federal Trade Commission warned that scammers were using AI to enhance family emergency schemes, noting that a short audio clip, such as one posted online, can be enough to clone a voice.
The voice is only the hook. The scam itself follows an old script: an emergency, pressure to act now, a request to keep it secret, and a payment method that is hard to reverse.
Common AI voice scam situations
Most AI voice scams fall into a few patterns. Knowing them makes the call easier to recognize while it is happening.
- Family emergency scam: a child or grandchild says they were arrested, had an accident or are stranded abroad and need money now. The grandparent scam with an AI voice is the best-known version.
- CEO fraud by voice: a voice message from “the boss” asks finance to pay an urgent invoice or change a supplier’s bank details, and not to tell anyone yet.
- Bank impersonation: a “fraud team” caller asks you to move money to a “safe account” or read out a one-time code.
- Kidnapping hoax: a crying voice, then a stranger demanding a ransom with no time to check.
How to protect yourself from an AI voice scam
Three habits stop most voice scams, and none of them needs technology. Agree on them with your family and your finance team now, while nothing is happening.
The call-back rule
Hang up and call the person back on a number you already have, not the one that called you. Caller ID can be spoofed. If you cannot reach them, call another family member or a colleague who can confirm. A real emergency survives a two-minute check.
A family code word
Pick a word or question only your family knows, never posted online. Anyone calling with an emergency has to give it. Businesses can do the same with a verification step for any payment change requested by phone.
What banks never ask
Check your own bank’s fraud page for its exact list. Banks commonly state that they will never ask you to:
- move money to a “safe account” to protect it;
- read out a one-time passcode sent to your phone;
- share your PIN or full online banking password;
- pay with gift cards or cryptocurrency;
- keep the call secret from family or branch staff.
Talking to older relatives about the grandparent scam
Older relatives are often targeted because callers bet on their love and their trust in a familiar voice. Make the conversation practical, not frightening: agree on the code word together, write your current numbers on a card by the phone, and tell them plainly that you will never be upset if they hang up and call you back to check.
How to stop CEO fraud by voice in your company
CEO fraud by voice is stopped by payment controls, not by spotting the fake. A cloned executive voice only works if one person can move money on a phone call or voice note.
- No exceptions for seniority: urgent payment requests from executives follow the same checks as everyone else.
- Any change of supplier bank details is confirmed by calling the supplier on a number already on file, never one given in the request.
- Payments above a set amount need a second approver.
- Requests for secrecy, such as “do not tell anyone yet, it is a confidential deal”, trigger a check by default.
- Finance staff know they will be thanked, not blamed, for delaying a payment to verify it.
Fraud teams that review suspicious calls and recordings will find a fuller workflow on the page for fraud and KYC teams.
How to know if a voice message is AI
You often cannot tell by ear. Modern clones sound natural, and phone compression hides the artifacts. Listen for flat emotion, odd breathing or pacing, and a voice that does not react to your questions, but trust the context more than the sound. The guide on how to tell if a voice is AI goes deeper.
- 01Do not act on the message. Do not pay, share codes or call a number given in the message.
- 02Save the recording. Most messaging apps let you export or forward voice notes.
- 03Use the call-back rule to reach the person directly.
- 04Run the recording through AI voice detection if you want a second opinion or need evidence for your bank or employer.
- 05If you already paid, call your bank immediately on the number on your card, and report the scam to the police or your national fraud reporting service.

Which AnyFact detectors help, and what do they return?
Two detectors fit voice scams. Both return a verdict (probably human, uncertain or probably AI), the signals behind it, a plain-language explanation, the limits of the method and a PDF report you can share with your bank or security team.
| Detector | Input | What it returns |
|---|---|---|
| Voice | MP3, WAV, M4A, OGG, WebM or OPUS, up to 25 MB and 5 minutes | A score per segment from an anti-spoofing model, a transcript, and flags for urgency, secrecy, money requests and changed bank details |
| Video | MP4, MOV or WebM up to 3 minutes, or a public video link | Suspicious moments on a timeline, a face-swap check when a frontal face is clear, and the soundtrack checked as voice |
Video matters because some scams now use video calls or video messages of an executive. The deepfake video detection tool checks both the image and the voice. The deepfake detector page explains how the photo, video and voice checks fit together.
AI Video & Deepfake Detector · Free plan
Check a recorded video message for face-swap signs and a cloned voice on the same timeline.
Limits of voice detection
AnyFact analyzes recordings, not live calls, so it cannot warn you during a conversation. Short clips, background noise and heavy phone compression make results less certain, and a genuine voice can be flagged. That is why the call-back rule and the code word come first: they work even when no tool can.
Frequently asked questions
How much audio does a scammer need to clone a voice?
Not much. The FTC notes that a short clip, such as one posted online, can be enough. Limiting public videos with your voice helps a little, but the call-back rule and a family code word protect you far more.
Can AnyFact check a live phone call?
No. AnyFact analyzes recorded audio and video files. Save the voice message or recording first, then upload it. During a live call, hang up and call back on a number you know.
What is CEO fraud by voice?
It is a scam where a cloned voice of an executive asks an employee to make an urgent payment or change a supplier’s bank details. A rule that every payment change is confirmed through a second, known channel stops it.
What should I do if I already sent money?
Call your bank immediately using the number on your card or its official website, explain it was a scam and ask them to try to stop or recall the payment. Then report it to the police or your national fraud reporting service. In the US, the FTC takes reports at ReportFraud.ftc.gov.
Is a voice check free?
AnyFact has a free plan. a free account gets 10 credits a month with no credit card, and a voice check costs 2 credits.
