Stupid question :) Smart Device work with Vera plus

i want a smart device or speaker to go on when my Vera Plus sees movement. So Vera Plus and motion sensor and then a smart device goes on. So what smart device i need? Google or a Amazon Echo? And how to make it work with Vera Plus?

ther are many tts options but i think alexa is the simpleist, take a look here

Or use Sonos speakers with Sonos plugin, updated by Rigpapa.
