Chapter 14, Voice Communication with a Robot Using Mycroft

• Why would the user define multiple variations for each vocabulary part?
  • When you talk, you naturally use synonyms: different ways to say the same thing. Without expressing those in the vocabulary file, Mycroft is not able to pick them up.
• Similarly, why would they do this for the dialogs?
  • To make Mycroft's responses seem more natural, as it will randomly pick synonymous phrases from the dialog
• Why did we wrap our intent with a try/catch?
  • So we can ensure that Mycroft speaks to us if it fails to contact the robot, and logs the problem somewhere
• What is the significance of the en-us string in the vocab/dialog file structures?
  • This is a language code. Mycroft will be allowing other language codes so it can be customized to many languages.
• How did we make the Pi start the pulseaudio system when it boots?...
