Here are a few hints for evaluating your ASR system with live input.

• On the solaris desktop, to access the necessary binaries, set the path as follows:
  export PATH=$PATH:/home/arnab/bin/htk/bin.sun4_solaris
  
• Using the left button of the mouse, access the audio control in the application menu and make sure the monitor volume in record mode is set to zero. Wear the head-mounted microphone and position the mic below your chin, out of the way of your exhalation.
• Record your input using the following command. Remember, the recognizer only knows about digits. It has been trained with natural sounding digit strings. To make your recording sound natural, it might help to write the numbers beforehand or use familiar number strings.
  audiorecord -p mic -c 1 -s 8000 -e linear test.wav
  
• Play back the audio to check the recording.
  audioplay test.wav
  
• Set the parameters of evaluation system. e.g.
  immf=/export/arnab/work/summer-school06/live/MMF
  dict=/export/arnab/work/summer-school06/live/dict
  mlist=/export/arnab/work/summer-school06/live/wrdlist
  wdnet=/export/arnab/work/summer-school06/live/wdnet
  cfg=/export/arnab/work/summer-school06/live/CF.file
  
• Now, decode the utterance.
  HVite -T 1 -C $cfg -H $immf -w $wdnet $dict $mlist test.wav
