<b>Introduction:</b>

<br>

<ul>
	The demonstrations in this directory are intended to show the
	functionality of the various classes created to deal
	with human speech. Currently, all of the programs are
	based on the <a href="http://communicator.sourceforge.net">Galaxy
	Communicator</a> architecture, requiring that the
	<a href="http://communicator.sourceforge.net">Galaxy Communicator</a>
	package be installed in order to compile and run any of the
	demonstrations.
</ul>

<br>

<b>Program Descriptions:</b>

<ul>

  Demo Selector:
	<br><br>
	<ul>
	  This program is the starting point for any of the CAVS demonstrations.
		It allows the user to graphically select which demonstration he would
		like to run.  Upon termination of the selected demonstration, the Demo
		Selector screen returns to allow the user to select another demonstration
		or exit the program.
	</ul>
	
	<br><br>
  
  In-Vehicle Dialog:
  <br><br>
  <ul>
    This demonstration represents the culmination of all the ISIP speech
		technologies. The program accepts requests from the user that pertain
		to directions or locations.  The utterance's energy, waveform, and
		spectrogram are displayed by the program in real time.  The program
		then interprets the meaning of the request and displays output based
		on the interpretation.
		<br><br>
		Example Requests:
		<br><br>
		<ul>
		  "Give me directions to Bulldog Lanes."<br>
			"How do I get from the University Book Mart to Old Venice?"<br>
			"Where is the nearest Radio Shack?"<br>
			"I am at Kroger. How can I drive to KFC?"<br>
		</ul>
		<br>
		The previous examples are by no means exhaustive. The system is capable
		of recogizing many commands.  For more information, visit the
		<a href="http://www.isip.msstate.edu/projects/ies/projects/dialog/">
		Dialog System Homepage</a>.
  </ul>
	
  <br><br>
	
  Speech Analysis:
  <br><br>
  <ul>
    This demonstration allows the user to record and playback utterances.
		The utterances are saved on the server side as a <code>RAW</code> file
		and saved on the client side as both a <code>RAW</code> and a 
		<code>WAV</code> file. The program also displays the energy, waveform,
		and spectrogram representations of the utterance. All three plots
		are calculated and graphed in real time.
  </ul>
  
  <br><br>

  Speech Recognition:
  <br><br>
  <ul>
	  This demonstration accepts an utterance from the user and displays
		the text of the utterance.  The energy, waveform, and spectrogram of
		the utterance are also displayed in real time.
	</ul>
	
	<br><br>
	
	Speaker Verification:
	<br><br>
	<ul>
	  This program demonstrates the ability to verify the identity of a
		speaker based on a short utterance. The user first gives the system
		a base sample for comparison. The system is then able to determine
		if other utterances are from the same speaker.  Also, the energy,
		waveform, and spectrogram of the utterance are displayed in real time.
	</ul>
</ul>
