title: How to use mozilla deepspeech to convert speech to text using it's pre-trained model?
body: <p>I want to convert speech to text using mozilla deepspeech. But the output is really bad.</p>
  
  <p>I have downloaded mozilla's pre trained model and then what i have done is this:</p>
  
  <pre><code>
  
  BEAM_WIDTH = 500
  
  LM_WEIGHT = 1.50
  
  VALID_WORD_COUNT_WEIGHT = 2.10
  
  N_FEATURES = 26
  
  N_CONTEXT = 9
  
  
  ds = Model(model, N_FEATURES, N_CONTEXT, alphabet, BEAM_WIDTH)
  
  
  fs,audio = wav.read(path)
  
  
  data = audio[:,0] ## changing to mono channel (using only one channel)
  
  prediction = ds.stt(data,fs)
  
  print(test)
  
  print(prediction)
  </code></pre>
  
  <p>Now the output is nowhere near to my audio sample. What do i have to do to increase it's accuracy?</p>
