According to Amazon, the Echo’s Alexa voice assistant misheard a word as “Alexa” — a trigger to activate the device — and interpreted subsequent conversation as a “send message” request. That […]

The problem is as old as data-processing itself: garbage in, garbage out. Assembling the large, well-labeled datasets needed to […]
