New developments in EPG3 software are described including: a three-dim
ensional display of the electrodes on the palate in the form of a wire
frame representation; a facility for annotating EPG3 files; and a new
data management system. Recent methods of EPG data reduction are also
described, including numerical indices for representing tongue-palate
contact profiles. A new clinical version of the Reading EPG system, E
PG4, is introduced.
