Remotely control Mopidy media service using Amazon Alexa

Motivation

• Want to control my home media center via Amazon Alexa voice control
  • Control playback
  • Change tracks
  • Change volume
• Want to try Alexa dev stack (this is my first attempt)

General structure

1. Alexa part
   • You should create and define custom Alexa skill
   • Skill should contain identity (how you will call it then, for example "Alexa, ask Mopidy to play")
   • Skill should contain list in intents, meaning distinctive actions that it shold be capable of (like play, stop etc). Intent may have slots - place where some variable should be, like "Alexa, ask Mopidy to set volume {FIVE}"
   • Skill should contain list of phrases mapped to each intent
   • Service hook that will implement custom logic behind intents
   • After skill definition is done you can enable it for your account
2. Service part
   • Should receive json requests from Alexa, already recognized and parsed, simlified just something like

   {
       "intent": "SetVolume",
       "slot": {
           "value": 10
       }
   }  
   

   • Should do something with it and reply to Alexa with specific text that she should reply to user
   • In my case put requst into IoT hub, where it can be captured by next layer of app
   • Receive speach reply from service or notify user if device didn't reply within timeout
3. Mopidy service part
   • Should subscribe to IoT hub and wait for messages
   • Upon receiving call appropriate JSON RPC service (or do chain of calls)
   • Reply back to sender positive or negative response
