Amazon has patented a voice-controlled drone that fits in your pocket

Tiny voice-controlled drones could film police videos and or help find where you parked your car.

Amazon won a patent today for a voice-controlled drone small enough to fit in your pocket. Imagine an Echo flying off your kitchen counter to act as an Alexa-powered aerial assistant.

The technology, Amazon says in its filing, may be better suited for police videos than dashboard-mounted cameras. It can help find lost cars in parking lots, say, or lost children in a grocery store; it can rubberneck for someone waiting in line to buy tickets to see how many others are waiting ahead.

The drones would respond to voice commands or instructions from an app and return to wherever the drone operator currently is.
