Functions
static bool	IsPlausibleWord (const WordAlignLatticeLexiconInfo &lexicon_info, const TransitionModel &tmodel, int32 word_id, const std::vector< int32 > &transition_ids)
static void	MapSymbols (const WordAlignLatticeLexiconInfo &lexicon_info, CompactLattice *lat)
	Testing code; map word symbols in the lattice "lat" using the equivalence-classes obtained from the lexicon, using the function EquivalenceClassOf in the lexicon_info object. More...
static bool	TestWordAlignedLattice (const WordAlignLatticeLexiconInfo &lexicon_info, const TransitionModel &tmodel, CompactLattice clat, CompactLattice aligned_clat, bool allow_duplicate_paths)
bool	WordAlignLatticeLexicon (const CompactLattice &lat, const TransitionModel &tmodel, const WordAlignLatticeLexiconInfo &lexicon_info, const WordAlignLatticeLexiconOpts &opts, CompactLattice *lat_out)
	Align lattice so that each arc has the transition-ids on it that correspond to the word that is on that arc. More...
bool	ReadLexiconForWordAlign (std::istream &is, std::vector< std::vector< int32 > > *lexicon)
	Read the lexicon in the special format required for word alignment. More...

Variables
