Detailed Description

Lexical tree node data type.

Not the first HMM for words, which multiplex HMMs based on different left contexts. This structure is used both in the dynamic HMM tree structure and in the per-word last-phone right context fanout.

Field Documentation

hmm_t chan_s::hmm

Basic HMM structure.

This must be first in the structure because chan_t and root_chan_t are sometimes used interchangeably

Definition at line 65 of file ngram_search.h.

Referenced by ngram_search_alloc_all_rc(), and ngram_search_free_all_rc().

int32 chan_s::penult_phn_wid

list of words whose last phone follows this one; this field indicates the first of the list; the rest must be built up in a separate array.

Used only within HMM tree. -1 if none
