That familiar voice on the phone might not be who you think.

The familiar part can be the trap

An unexpected caller sounds like someone you know. They say something has gone wrong and need help immediately. The emotional pressure can make checking feel like wasting time.

The US Federal Trade Commission has warned that scammers can use AI to imitate a relative’s voice for a fake family emergency. Its practical advice is to call the person using a number you already know, rather than trusting the incoming voice alone.

You do not need to become an audio detective. A reliable way to confirm the request is more useful than trying to hear a tiny flaw in the recording.

Agree on a routine before anyone is rushed

Have a short family conversation about unusual requests. The point is to make a callback feel normal, even if a caller sounds upset or insists there is no time.

For example, you might agree that an unexpected request involving money will always be checked through an existing contact number. If the person cannot be reached, another trusted family member can help establish what is happening.

Explain the routine without embarrassment or blame. People are more likely to ask for help when they know the response will be calm.

• Pause before sending money or revealing private information.
• End the call and use a number already saved in your contacts.
• Keep sign-in codes and account passwords out of the conversation.
• For an organisation, find its contact details in its official app or website.

Phone warnings can help, but they are only one layer

In June 2026, Google announced fake-call detection for supported Phone by Google situations, designed to flag certain impersonation attempts during calls. Availability depends on the supported setup and rollout.

A warning can be a useful reason to stop. The absence of one should not replace your own verification routine. Different phones and apps offer different protections, and a caller’s story still needs to make sense.

If you want to use a protection feature, look for it in the official phone app’s settings and documentation rather than following a link sent by an unexpected caller.

Make checking a sign of care

A genuine relative may find an extra callback mildly inconvenient. That is easier to manage than a rushed decision based on an unverified story.

The most practical response to more convincing imitation is a habit that does not depend on recognising imitation at all. Slow the conversation down, choose your own trusted route back, and confirm what is being asked.
