Endpointing (ep) Parameters:
  
  nuance.core.ep.EndSeconds
  Type: float  
  Default: 0.75  
  Minimum: 0.20  
  Maximum: 10.00
  
  Specifies the minimum amount of silence required to indicate 
  that the end of speech has occurred. A longer value is less 
  likely to cut the talker off, but also makes the interaction 
  slower. This parameter is often set from within applications, 
  based on the type of response expected from the user. For 
  example, 0.5 seconds might be appropriate for a simple yes/no 
  question, whereas 1.5 seconds might be more appropriate when 
  a talker is likely to pause mid-sentence.

  nuance.core.ep.PrepareForBargeIn
  Type: bool  
  Default: false
  
  Set to TRUE if your system includes barge-in to allow the 
  endpointer to provide better performance. This enables the 
  endpointer to better detect start of speech that occurs 
  during prompt playback. 

  nuance.core.ep.ThresholdSnr  
  Type: int  
  Default: 10  
  Minimum: 5  
  Maximum: 30
  
  Controls the threshold of noise the endpointer needs to detect 
  start-of-speech and end-of-speech. To reduce the likelihood of 
  false detection in noisy environments, you can increase the 
  value of this parameter. However, this requires the user to 
  speak more loudly to be heard. Typically you never need to 
  modify this parameter. Increasing the value of this parameter 
  makes the application less sensitive to barge-in. 
  
*TTS = text to speech
