Gadgets You Can Speak With?

Today there is a wide array of gadgets that human beings can speak with. The question we ask is why? Essentially, because it's easier to use speech communication to interact with all a gadgets features than to fill it with millions of buttons - which is difficult as humans want their tech devices to be ever-smaller. So besides voice recognition for simple tasks, there are larger points on the horizon.
For example, you can speak to your cell phone or computer and ask it to order you a pepperoni pizza! Since the system that allows this communication is so complex it would be impossible to install it on millions of cell phones, thanks to the fact that most cell phones are now connected to the Internet it's finally possible. The technology itself works quite simply through voice recognition software: the software analyzes the person's speech and translates it into digital commands that are sent back to the device.
