I would like to add to this list of questions 

   * How reliable is voice recognition in noisy environments with
     respect to vocabulary size?  For example if the system only
     needs to recognize 50 or so words, is that more robust than 
     a 5000 word system? How much more reliable? Don't know answers
     would be preferable to wrong answers.
