title: Convert Audio File to text using System.Speech
body: <p>I am looking to convert a .wav file recorded through an android phone at 16000 to text using C#; namely the System.Speech namespace. My code is mentioned below;</p>
  
  <pre><code>recognizer.SetInputToWaveFile(Server.MapPath("~/spoken.wav"));
  recognizer.LoadGrammar(new DictationGrammar());
  RecognitionResult result = recognizer.Recognize();
  label1.Text = result.Text;
  </code></pre>
  
  <p>The is working perfectly with sample .wav "Hello world" file. However when i record something on teh phone and try to convert to on the pc, the converted text is no where close to what i had recoreded. Is there some way to make sure the audio file is transcribed accurately? </p>
