@Sean i mean i want to set default question and answers with voice response (using google TTS. I dont know how to command to create . :(

How can google TTS respond to the answers I have prepared? eg :

• “smart mirror, I want to drink something.” - Me
• “This is your drink.” - Smart mirror answers.
  So how to do that?
  I have successfully installed the api and modules, but i dont know how…
