It is cheaper to put microphone and ask for food, similar to regular shop: "Hey, Amazon", "Order, please", "Bottle of milk and bread", "Bottle of milk «Foo» $2,50. Bread «Bar» $1,75. Total: $4,25. Confirm?", "Yes", "Order accepted, wait for delivery.". Something like Siri, but activated by push of hardware button on the fridge.

Amazon released the Alexa Voice Service recently: https://developer.amazon.com/public/solutions/alexa/alexa-vo.... It takes advantage of the cloud functionality that powers Alexa but can be used on any device.
