'Echo Is Not Spying On You,' Amazon Lawyer Declares
"We designed the Echo devices very intentionally to only listen when spoken to … and also be incredibly conspicuous when it is listening,” [Ryan] McCrate said, referring to the ring of LED lights that flash when Alexa perks up.
McCrate’s brief remarks on the panel sounded at times like a promotional pitch touting the lengths the company took to protect consumer privacy.

But the company, he added, also realized there would be “well-founded” concerns about a product like the Echo."
