Every smart speaker has its advantages. With Amazon Echo , you get access to tens of thousands of "skills," the mini-apps that start a game of Jeopardy or help you mix a cocktail. With Google Home , you have the full power of Google search at your beck and call. And when Apple's HomePod comes out later this year, it'll be by far the best-sounding voice-enabled speaker of the bunch. Sony doesn't have a voice assistant, but knows its way around a speaker.
