Electric familiar
If you're going to have a personal drone fleet, you need an easy way to command it. The Wicked Witch of the West didn't use an RC transmitter: She said "Fly, fly, fly!"
Years ago I worked on a project for the Air Force Research Lab involving natural language interfaces. We tried to sell some of the technology to Boeing to help reduce drone operator workload, but this was before the Drone Era had really gotten started, and they weren't interested. This is a crude demo of using some of that same technology to control an AR.Drone with my voice.
In the video I'm speaking into my laptop, which is controlling the drone. At the end of the video you get to witness a stubbornly unresponsive drone—The result of a software crash.
There is interest in using speech interfaces to help ease the integration of drones into the National Airspace System. For example, one issue that the FAA (and the military) worry about is what happens if the communications link between a drone and its operator is broken. The safest thing would be if the drone could still respond to commands from Air Traffic Control, autonomously. This is why level 2 of NASA's UAS Airspace Operations Challenge requires "that the vehicle be able to communicate verbally with the Air Traffic Control system under lost link conditions."
