ISIP decoder v3.3 integrates the functions of lattice rescoring,
force alignment, N-Gram decoding and N-Gram lattice generation.
The mode can be selected from the command line by choosing
-lattice, -ngram or -forcealign.
Another two new options being added to command line are:
-h : number of histories at each word (default 1)
-n : n-best hypotheses to be output (default 1)
In N-Gram decoding and lattice generation, bigram and trigram
language model are used.
