Explanation
AI voice cloning technology allows a convincing synthetic voice to be generated from a short audio sample. Scammers have used this to impersonate bank staff, financial advisers, family members, and executives during phone calls. The caller sounds natural, can hold a basic conversation, and may match the accent and tone of the person they mimic. Combined with caller ID spoofing, the call appears to come from a legitimate number. At the banking level, the AI voice may instruct you to confirm a transaction, provide a one-time code, or authorise a large payment. Your bank will never call you to ask for an OTP or PIN. If a call feels even slightly unusual, hang up and call your bank on the number on the back of your card.
Common red flags
- Caller asks for an OTP, PIN, or password over the phone
- Instruction to authorise or confirm a payment you did not initiate
- Caller sounds slightly robotic or pauses unnaturally
- Caller becomes evasive when asked unexpected questions
- Caller ID matches your bank but the request is unusual
What to do now
- Hang up and call back on a number you find independently
- Never share an OTP or PIN on an inbound call
- Ask your bank to add a verbal security passphrase to your account
- Report the call to your bank's fraud team and national fraud service
Frequently asked questions
How can I tell if I am speaking to an AI voice?
AI voices may pause unnaturally, struggle with unexpected slang, or repeat phrases. Asking an unexpected personal question about the supposed caller can reveal inconsistencies.
