Meta Files Patent for AI That Can Listen All Day and Track How You're Feeling

### Executive summary Meta filed a patent for an AI system that continuously or periodically records speech (via phones, glasses, headphones, smart speakers), transcribes and analyzes tone alongside biometric signals (pupil size, blink rate) and device-use data to log timestamped emotional readings and optionally deliver a mood-aware workout coach; the filing raises privacy and regulatory concerns but does not indicate an existing product or any cybersecurity incident.
