Shhh, Your Washing Machine Might Overhear You
Alexa, are you spying on me? It’s a fair question in light of attempts by authorities investigating the slaying of an Arkansas man to obtain voice recordings collected by an Amazon Echo speaker and its Alexa digital assistant.
Yet the popularity and capabilities of voice-enabled products such as the Echo continue to grow.

Some experts worry that allowing such a search would erode people’s privacy.
