📡 AI radar that listens in

Penn State researchers unveiled Wireless-Tap — a system that uses millimeter-wave radar and AI to transcribe phone calls from up to 3 meters away. It picks up microscopic vibrations on your phone’s body during a call and converts them into text with a tuned version of OpenAI’s Whisper.

Accuracy hits 60%, vocabulary up to 10 000 words. The sensors? Off-the-shelf, from self-driving cars and 5G tech. The team claims it’s just a security demo, but the takeaway is clear — call privacy isn’t what it used to be.

💡 Moral: if you think you’re speaking “just to yourself,” tech already begs to differ.#AI
