title: Is it possible to see remaining valid choices during speech recognition?
body: <p>I am working with System.Speech.Recognition.Choices class, and I would like to have a way to present to the user the possible choices remaining for the given speech session (I'm not sure of the correct term here). </p>
  
  <p>For example, if the choices are "thermal", "thermite", and "off", then I would like to show a list with all three. If the user starts the "th" sound, I would like to show only the first two, and as the user continues have the other choices fall off. Basically, I want to display the remaining possible choices.</p>
  
  <p>Is this possible?</p>
  
  <p>Thanks!
