I was thinking about making my own as well! I haven't done any research but you'd need a smartphone dock, a good microphone/speaker (wireless microphones/speakers around the house?!?). Better yet, mount a tablet on the wall somewhere convenient/attractive (living room, next to thermostat, etc.) and wire everything behind it.
Change Android settings to always listen when screen is on, then keep screen always on (dims when not active). Voice-controlled App support galore! Google Now! Develop whatever you need/want!
The Echo is a neat idea put into action, but it can be hacked together in a much better way, very easily.
