The video below by Leon Nicholls shows what is possible with Amit Jotwani’s Alexa Voice Service project powered by a Raspberry Pi. The trick was to see if any one service’s voice-activated command could prompt another service, thus getting them to talk to each other.

You will be using the Node.js server to get a Login with Amazon authorization code by visiting a website using your computer’s (Raspberry Pi in this case) web browser.
