title: how to get frequency of audio at specific time in python?
body: <p>I am working on mp3 file to get the speech in the form of text with speech_recognization python. Here I need to get the text from mp3 file for every 10sec. I am not able accurate results. so my idea is to get the frequency of the audio for every 10sec, if the frequency is too low then I want to convert audio to text to that point.(I don't want to use numpy, scipy, matplotlib).</p>
  
  <p>Please give your valuable suggestions.</p>
