JavaSpeech dictation grammars

[Jane Dunne]

Hi, I'm using the JavaSpeech API and I want to dictate information into my application. I've already inputted speech using a rule grammar as follows:

FileReader grammar1 = new FileReader("gram.txt");
RuleGrammar rg = recognizer.loadJSGF(grammar1);
rg.setEnabled(true);

I'm not sure how to go about loading a dictation grammar though, as you don't specify a particular set of rules in a text file. This is probably a very simple question but I can't seem to find the answer anywhere! Any help would be greatly appreciated.
