Millions of people already have an AI-powered voice assistant in their homes. Privacy issues regarding voice listening capabilities of such devices are raising concerns. They do listen to you all the time, but will send what you say to the cloud for processing only after they hear predefined activation words.

Some devices have sometimes misinterpreted requests as shopping orders, so you may end up with an expensive toy that you actually didn’t order.”]
