title: Filter out speech containing audio files from rest of the audio files in my android app
body: <p>I am building an android app that would record audio and store it in the phone storage as 30 seconds long audio files each. What I want to achieve here is to discard those audio files which contain any kind of speech. I only want non-speech audio files for further processing.</p>
  <p>I have gone through speech recognizer class for android, but it only works for live audio. I want to detect speech on saved audio files and discard those files if any form of speech is detected. How can I achieve this?</p>
