Programming a voice agent with Mycroft on the Raspberry Pi

The robot backend provided by the Flask control system is good enough to create our Mycroft skill with.

In Figure 15.4, you saw that after you say something with the wake word, upon waking, Mycroft will transmit the sound you made to the Google STT system. Google STT will then return the text.

Mycroft will then match this against vocabulary files for the region you are in and match that with intents set up in the skills. Once matched, Mycroft will invoke an intent in a skill. Our robot skill has intents that will make network (HTTP) requests to the Flask control server we created for our robot. When the Flask server responds to say that it has processed the request (perhaps the behavior is started), the robot skill will choose a dialog to speak back to the user to confirm that it has successfully carried out the request or found a problem.

We'll start with a simple skill, with a basic intent, and then you can...
