​Google has introduced a new fake call detection feature for Android devices to help users identify AI-driven phone scams. This tool targets calls where scammers use AI-generated voices and spoofed phone numbers to impersonate trusted contacts, including family members and colleagues.

Key Highlights

• Google introduces fake call detection to combat AI voice scams on Android devices.
• Feature verifies both caller's device and phone number to detect impersonation attempts.
• Technology uses digital handshake and RCS for broader compatibility and future adoption.
• Rollout begins globally for Android 12 and newer devices using Phone by Google.

Rising Threat of AI Voice Scams

Cybercriminals are increasingly using advanced technology to make their scams more convincing. Traditionally, fraudsters relied on spam calls, phishing, and fake customer support schemes. As people became more cautious and avoided unknown numbers, scammers adopted new strategies.

One major tactic involves spoofing phone numbers to make calls appear as if they come from familiar contacts. Scammers then use AI to mimic the voices of family members, employers, or authority figures. Experts note that AI-generated voices have become so realistic that many people cannot distinguish them from real voices. This creates a situation where victims may trust both the caller ID and the voice they hear.

How Google's Detection Feature Works

Google’s new system aims to verify not just the voice, but the device making the call. The technology operates as a digital handshake between phones. When a trusted contact calls and both devices use Phone by Google, the caller’s phone silently sends a verification signal. This confirms the call is genuinely coming from that device.

If a scammer tries to impersonate a contact by spoofing their number, the verification signal will be missing. Your phone will then check with the actual device of the contact. If the real device confirms no call is being made, Android will display a warning that the caller may be an impersonator and recommend hanging up.

This approach means that even if scammers can clone someone’s voice, they may not be able to fake the device behind the call. The feature is rolling out globally this month through Phone by Google on Android 12 and newer devices.

Broader Implications and Future Adoption

Google built this technology on top of Rich Communication Services (RCS). This foundation allows other apps and companies to potentially adopt similar protections in the future. As AI tools make scams more sophisticated, traditional advice to trust familiar voices is becoming less reliable.

Google’s latest feature focuses on verifying the source of the call, not just the sound of the voice. This approach may help users distinguish between genuine contacts and scammers, even as voice cloning technology advances.
