+<a href="http://htk.eng.cam.ac.uk/develop/atk.shtml">ATK</a> recognizer and

+network which accepts strings in the currently active grammar.
+In order to use the <tt>si</tt> command,

+and <tt>GF_ATK_CFG</tt> should contain the path to your GF ATK configuration
+file. A default version of this file can be found in
+ <tt>GF/src/gf_atk.cfg</tt>.
