DetectifAI fights deepfake voice scams with on-device AI
After her grandfather was scammed by a deepfake voice, Tarini Padmanabhuni founded DetectifAI, a San Francisco-based startup that develops compact AI models for real-time deepfake voice detection directly on smartphones. The company licenses its SDK to phone manufacturers, aiming to embed detection as a built-in OS feature. DetectifAI currently handles over 100,000 calls per month for financial institutions in India, providing deepfake detection and speaker verification. The startup has raised a small seed round from investors including Josh Constine and Manohar Kamath. It is also set to compete in TechCrunch's Startup Battlefield at Disrupt 2026. The FBI reports Americans lost nearly $900 million to AI-driven scams last year, highlighting the growing need for such technology.

10-Day AI Voice Agent Stops Scam Calls
A developer built 'Suraksha Saathi', an AI voice agent prototype to help families detect and respond to scam calls in 10 days. The agent uses Deepgram for speech recognition, a Google Gemini model for reasoning, Murf AI's Falcon TTS for fast speech output, and LiveKit for real-time connectivity. Features include Hindi support via Devanagari-only output, a consent-based memory to remember callers, a panic button that alerts a human fraud team via Discord, real-time scam tracking dashboard, and mid-call voice-engine handoffs to escalate to an investigator persona. The author published the post on DEV and shared source code on GitHub.
Google launches fake-call detection to block AI deepfakes
Google announced a new fake call detection feature for Android that aims to protect users from AI voice deepfake impersonation scams. Rolling out globally this month in the Phone by Google app for Android 12+ devices (starting with Pixel phones), the feature is enabled by default and runs automatically. It uses a silent confirmation signal — described as a “digital handshake” built on Rich Communication Services (RCS) — between devices when both caller and recipient use Phone by Google; missing confirmation triggers a verification ping to the caller’s device and, if the real device confirms no call is in progress, the recipient sees a warning to hang up. The announcement was published June 2, 2026, alongside other Android updates such as Google Photos’ wardrobe feature and Play Books’ recap tools.
Study: Deepfake Voice Scams Could Cost Americans $40B
An Insuranceopedia analysis estimates deepfake voice scams could cost Americans about $39.7 billion per year in a base-case scenario, using FTC median loss figures and surveys showing widespread exposure. The study cites research from Hiya, McAfee, the FTC, and U.S. Census data, and reports that roughly 25% of Americans received a deepfake voice call in the past year and that 77% of those victims reported losing money. Regulators and platforms are responding: the FCC adopted strengthened Know-Your-Customer rules for voice providers and proposed additional rules to hold providers accountable, while platforms have expanded likeness-detection tools. The article provides consumer tips to verify callers and avoid rapid-payment scams.
