Amazon announced its surprising new echo device last week, but what exactly is echo? The amazon echo is a speaking, talking, interactive piece of furniture that can be used hands free for multiple things. Echo uses Far-field voice recognition, Bluetooth, and mics to create a hands free personal assistant. Students can sit the device in a room and ask echo to play music, add things to your shopping list, set alarms or reminders for homework, and weather. The device will start out at 199, but amazon prime members can scoop one up for 99 dollars.
