Hands Free Interactions

Voice is a more natural way for humans to interact with machines. Such interfaces become even more essential in certain situations where hands and eyes are already busy. A common example is in the car, while someone is driving. This is an environment where voice interfaces became common more than a decade ago. While the constraints in a car are more stringent, in home environments the added convenience of a voice interface is leading to its wider use. For instance, looking up recipes or making a grocery list is way more convenient if you can just speak to a device, rather than having to pick up a phone, open an app, and enter the information. Systems such as the Amazon Echo provide interfaces to home automation so that one can control machines and appliances in the home remotely using voice commands.
