title: voice recognition constantly in background android
body: <p>FfhggtffgtfgtgftI want develop application that whenever it recognizes a keyword it does something. it needs to be in listening mode all the time, in backgeound too.
  I was exposed to <a href="https://alphacephei.com/vosk/android" rel="nofollow noreferrer">this</a> and <a href="https://cmusphinx.github.io/wiki/tutorialandroid/" rel="nofollow noreferrer">this</a>. I treid run it but it is not work when I am speaking.
  actually I read it still doesn't support my native language. is that the reason?
  I want to know how it works? does it is doing speach to text and saved it in assets files? does it is run in background? does it is used AI models? how it behaves when two apps need mic resource in parallel? noises? does it is work with Neural Networks API? how can I start developing such a thing?</p>
  <p>thanks!</p>
