title: unintentional pitch change using MS SAPI TTS
body: <p>Has anyone else experienced (and possibly solved) unintentional pitch changes using MS SAPI TTS voices? </p>
  
  <p>I'm using the SpVoice automation interface with SAPI 5.1.</p>
  
  <p>Right now, my application (VB6 app) can get into a state where the TTS (Microsoft Anna) starts to sound like a chipmunk (proper rate, but high pitch) and even a reboot of Vista does not correct the issue. </p>
  
  <p>I'm passing in XML to the Voice.Speak() function. I've tried sending &lt; pitch absmiddle="0" /> before all other XML and it still does not correct the pitch issue. When I try the TTS voice preview in the Speech control panel, the voice has a normal pitch.</p>
  
  <p>The issue has occurred for me in XP in the past, however a reboot seemed to correct it.</p>
