Detailed Description

A note by ARCHAN at 20050703

In general, what made a LVCSR search to be unique has three major factors. They are 1) how high level knowledge source (LM, FSG) is applied, 2) how the lexicon is organized, 3, how cross word triphones is realized and implemented. It is important to realize the interplay between these 3 components to realize how a search actually really works.

Member Data Documentation

hash_table_t* srch_WST_graph_t::active_word

Hash table that map word end to the index of the expandtree.

lextree_t* srch_WST_graph_t::curfillertree

The first filler tree

lextree_t* srch_WST_graph_t::curroottree
         The first unigram tree that used

in the search for this utterance.

glist_t srch_WST_graph_t::empty_tree_idx_stack
        Store a pool of indices which

indicate a tree is empty. It acts like a stack

lextree_t** srch_WST_graph_t::expandfillertree

The expanded fillertrees

lextree_t** srch_WST_graph_t::expandtree

The expanded trees

histprune_t* srch_WST_graph_t::histprune

Structure that wraps up parameters related to

int32 srch_WST_graph_t::isLMLA

Is LM lookahead used?

lmset_t* srch_WST_graph_t::lmset

The LM set

int32 srch_WST_graph_t::n_static_lextree

Number of static lexical tree for word switching

int32 srch_WST_graph_t::no_active_word

No of active word

lextree_t** srch_WST_graph_t::roottree
           The pool of trees that stores all

word trees. An array with dimension. #lm
