TTSApp is an example of a text-to-speech (TTS) enabled application. This sample application is intended to demonstrate many of the features for SAPI 5 in a single coherent application. It is not a full featured TTS-enabled application although the foundations of many of the options are present.

TTSApp allows you to hear the resulting audio output from the TTS process for text entered in the main window. Alternatively, you can open a file and TTSApp will speak the contents of that file.

Each word is highlighted in the text window to indicate the current TTS processing position. Features include:

• 
  SAPI5 TTSApp main window.
  Use the main TTSApp window to select the configuration settings that affect the TTS process. The elements of TTSApp are listed above. Click the text in the left column for additional information.

• 
  Process XML
  Select Process XML to include the XML tags and their contents in the audio output stream from TTSApp. When this option is selected, the application will parse and interpret the XML tags literally.

  For example, if the Process XML option is selected, the application could be paused for the specified number of milliseconds in the SILENCE tag.

  Process XML	XML tag	Result
  	<SILENCE MSEC = "3000"/>	The application would speak 3000 milliseconds of silence.
  	<SILENCE MSEC = "3000"/>	The application will speak the phrase, "less than silence msec equals quote three thousand quote slash greater than."

• 
  Mouth Position
  The mouth position displays the various mouth shapes and positions as TTSApp processes the input text stream.
