title: realistic free TTS program
body: <p>I have tried Festival, espeak, and MBROLA, but the voices are mediocre at best, and no where near as realistic as current commercial systems. eg this demo: <a href="http://www.acapela-group.com/text-to-speech-interactive-demo.html" rel="nofollow noreferrer">http://www.acapela-group.com/text-to-speech-interactive-demo.html</a></p>
  
  <p>What is the most realistic free TTS voice you have tried?</p>
