Detailed Description

Structure Definition of tree lexicon.

This file defines structure for word-conjunction HMM, aka tree lexicon for recognition of 1st pass. Words in the dictionary are gathered to build a tree lexicon. The lexicon is built per HMM state basis, with their HMM output probabilities, transition arcs, and other informations for search such as successor word lists and maximum uni-gram scores for LM factoring, word head/tail marker, phoneme start marker, and so on.
