Google Phone app detects AI scams mimicking your contacts

Scammers have found a new way to exploit trust—and it’s costing Americans millions every year. Using AI voice cloning, fraudsters now impersonate friends, family, or even authority figures to trick victims into handing over money or sensitive data. Beginning this week, Google’s Phone app is rolling out a feature to combat these schemes by detecting when a call appears to come from a contact but may actually be a scam.

The update arrives as impersonation scams surge across the U.S. In 2025 alone, the FBI reported that Americans lost over $893 million to scams that employed AI-generated voices, according to the agency’s annual Internet Crime Report. The tactic is simple yet devastating: scammers spoof a phone number belonging to someone you know, then use AI to replicate their voice, making the call seem legitimate. Google’s new feature aims to disrupt this process by flagging suspicious calls directly in the Phone app before users answer.

How the AI call detection feature works

When activated, the feature analyzes incoming calls for signs of spoofing or AI manipulation. If the app detects that a call appears to originate from a contact but exhibits unusual patterns—such as an unfamiliar voice or inconsistent background noise—it will display a warning label on the screen. This label reads “Suspected scam” or “Possible impersonation,” giving users the information they need to pause before engaging. Google notes that the detection relies on a combination of machine learning models trained on vast datasets of legitimate and fraudulent calls.

What you should do if you receive a flagged call

• Do not answer immediately. Pause and verify the caller’s identity through a separate channel, such as a text message or a callback to the known number.
• Check for red flags. Be wary of urgent requests for money, personal information, or unusual questions that the alleged caller wouldn’t normally ask.
• Report suspicious calls. Use the app’s built-in reporting tools to help Google improve its detection models and warn other users.
• Enable the feature. The update applies to all users with the latest version of Google’s Phone app on supported Android devices. Ensure automatic updates are enabled in your device settings.

Google emphasizes that while the feature adds a critical layer of protection, it isn’t foolproof. Scammers continue to refine their tactics, and no detection system is 100% accurate. Users should remain vigilant and combine the app’s alerts with common sense and skepticism.

The rise of AI-powered scams marks a troubling evolution in digital fraud, but tools like Google’s updated Phone app provide a meaningful response. As voice cloning technology becomes more accessible, proactive defenses will be essential to safeguarding personal and financial security. Staying informed and leveraging built-in protections can help users stay one step ahead of scammers.
