| 7.1 Use a 
              Natural Text-to-Speech Engine
              This tutorial uses many Text-to-Speech prompt items, some of them 
              are fixed text and others are dynamically generated text. If you 
              are using the shareware edition of Voicent Gateway, the TTS engine 
              included is a free one from Microsoft. One big problem for the 
              Microsoft TTS engine is that its computer generated voice is hard 
              to understand. 
              Voicent offers a much better Natural Text-to-Speech engine, with 
              both male and female voices. These voices have much better 'human' 
              quality and are easier to understand. The natural TTS engine is 
              fully integrated with Voicent Gateway. 
              For more information, please refer to

              Text-to-Speech Engine. 
              You can hear the voice samples by listening to any of our online 
              video demo.
