 grammarGen4ks: Generate grammar and net files for keyword spotting with FSD as the filler model
    sylFile: the file containing syllables of keywords
    dicFile: pronunciation dictionary
    grammarFile: output grammar file (You can use this grammar file to generate net file using hparse.exe in HTK.)

    For example:
        sylFile='tangPoem.hanyu.syl';
        dicFile='hanyu.dic';        % FSD (free syllable decoding) for filler
        grammarFile='tangPoem.hanyu.grammar';
        grammarGen4ks(sylFile, dicFile, grammarFile);
