title: I can't find System.speech
body: <p>I am trying to do a project that uses the windows speech recognition libraries and I am trying to add a reference to System.speech since I am using:</p>
  
  <pre><code>SpeechSynthesizer synth = new SpeechSynthesizer();
  </code></pre>
  
  <p>However, I can't find System.speech in the .NET tab when I try to add a reference. I updated my .NET Framework and still can't find it. Is there a way to simply add it?</p>
