How to Spot a Deepfake Voice Call

By Zakria Ahmad · 2 November 2026 · Last updated: 2 November 2026

What is a deepfake voice call?

A deepfake voice call is a phone call where a computer copies a real person's voice. The caller may sound like a bank manager, a relative, or a company worker, but the voice is made by AI. The aim is usually to make you trust the call and share a password, a PIN, an OTP, or money.

How does it work?

First, the scammer gets a short voice sample, for example from a video or a voicemail. Then AI software copies that voice. Then the scammer calls you, pretends to be someone you trust, and creates urgency, for example: "Your account will be blocked today, act now." The call feels real because the voice sounds real.

Red flags to check

  • The caller asks for a password, PIN, or OTP. A real bank never asks for these on a call.
  • The caller creates panic: "Act now, or your money is gone."
  • The caller asks you to install an app, give remote access, or buy a gift card.
  • The caller refuses to let you hang up and call back on the official number.
  • The voice sounds right, but the story does not match what you know.

Guard tip: Use a family secret word. If a relative or a bank manager calls, ask for the secret word. If they cannot say it, hang up and call back on the official number yourself.

What to do

  1. Stay calm. Do not share any code, password, or PIN.
  2. Hang up. Do not argue with the caller.
  3. Call the bank or the person back yourself, using the official number or app, never the number the caller gave you.
  4. Check your account only in the official app, never through a link in a message or call.

What not to do

  • Do not buy a gift card to pay anyone. A request for gift-card payment is a scam sign.
  • Do not give remote access to your phone or computer.
  • Do not send money because a voice sounded familiar. A familiar voice can now be copied by AI.

If you were already scammed

  1. Call your bank at once and ask them to freeze the account if needed.
  2. Change your passwords, starting with your email and bank accounts.
  3. Report the call to your bank and to the official cybercrime reporting service in your country, for example FIA Cybercrime in Pakistan, Action Fraud in the UK, or the FTC in the USA.
  4. Be careful of a second scam: anyone who asks for money to "recover" your money is also a scammer.
