# Brief description:
#
#  This shell script is an example of a script that displays a useful
#  set of speech data displays given a BASENAME common to all of the 
#  speech data files.  It also describes the commands used in the script.  
#  The script sends commands to xwaves using the send_xwaves command.  
#
#  This shell script creates and displays xwaves display ensembles
#  with a speech waveform, an f0 display, and a spectrogram.  Two 
#  label files (using xlabel) are associated to the speech waveform.
#
#  A full display ensemble $BASENAME consists of these files:
#      $BASENAME.sd	   ($SPEECH -- the speech waveform)
#      $BASENAME.f0	   ($F0 -- fundamental frequency)
#      $BASENAME.phones	   (an xlabel label file for labelling phonemes)
#      $BASENAME.words	   (an xlabel label file for labelling words)
#      $BASENAME.sd.fspec  ($SPECT -- a (wideband) spectrogram)
#
#  Additional referenced files: $ESPS_BASE/lib/waves/menus/actionsonlymenu
#			        $ESPS_BASE/lib/waves/menus/labelmenu.timit
#
#  Keep the terminal window accessible so that you can see the prompt
#  messages. 
#
#  This script has been tested with ESPS/waves+ version 5.1.


#-------------------------------------------------------------------------
#  Preliminary startup checks to see if it is ok to start xwaves and
#  start displaying ensembles.
#-------------------------------------------------------------------------

#  CHECK #1:  Make sure there are $BASENAME arguments specified.
#  Invoke the script with "showEnsemble BASENAME1 BASENAME2 ..."

case "$#" in
        0) echo "Usage: $0 BASENAME1 BASENAME2 ... "; exit 1;;
esac

#  CHECK #2:  Make sure that $ESPS_BASE is defined.

if test -z "$ESPS_BASE"
then
     echo "Please define the UNIX variable ESPS_BASE and try again."
     exit 1
fi

#  CHECK #3:  Make sure that $ESPS_BASE/bin is in the user's path so
#  that the send_xwaves and xwaves commands don't fail.

if test -z "`echo $PATH | grep $ESPS_BASE/bin`"
then
     echo "Please add $ESPS_BASE/bin to your path and try again."
     exit 1
fi
  
#  CHECK #4:  Make sure that the user doesn't lose the work of a 
#  current xwaves session.  
#
#  If xwaves is already running, check to see if there are any current
#  display objects.  If there aren't, go ahead and try to display the
#  ensembles.  If there are current display objects, warn the user.
#  If xwaves is not already running, try to start it.
#  
#  Checking for a current xwaves session is done by testing the
#  success of a command sent to xwaves ("set barr foo").
#  With option -D1, send_xwaves waits only 1 second to try to make a 
#  connection to xwaves.  If xwaves is running, it will be able to 
#  make a connection within 1 second.  If it isn't, it will not.
#  Suppress warning messages with "1>/dev/null 2>&1".  E.g.,
#	Cannot open a connection to xwaves
#  if xwaves is not already running.
#  
#  If there are no current display objects in xwaves, then 
#  "send_xwaves get aname objects" returns the string "" (i.e., \"\")
