Alexa doesn’t just know who you are—she now knows how you’re feeling.

In 2018, Amazon filed a patent for a new system that detects the physical and emotional wellbeing of users based on their previous and current interactions.

In 2019, it announced that its Rekognition suite (used by outside businesses and organizations) is capable of seeing fear in our faces, while Alexa can sense and understand frustration.

It’s also working on a voice-activated wearable that can help decode how others are feeling.

A real-world use case for the technology: Paired with smart earbuds, Alexa could advise the wearer in real time how to interact more effectively with others.
