In file SListener.java you have to find this:
String patternn = "([^\\.])\\1{2,}";

Change it with:
String patternn = "([\\D])\\1{3,}";

Now it gets everything except numbers.

Also, you can remove this lines:
String dot = "(\\.)\\1{3,}";
and
String msg = msg1.replaceAll(dot, "...");

and last, change:
String msg1 = rawmsg.replaceAll(patternn, r);
to
String msg = rawmsg.replaceAll(patternn, r);


That's it. :))
