Member Data Documentation

◆ ctr_latentry

pctr_t* srch_FLAT_FWD_graph_s::ctr_latentry

◆ ctr_mpx_whmm

pctr_t* srch_FLAT_FWD_graph_s::ctr_mpx_whmm

◆ ctr_nonmpx_whmm

pctr_t* srch_FLAT_FWD_graph_s::ctr_nonmpx_whmm

◆ ctxt

ctxt_table_t* srch_FLAT_FWD_graph_s::ctxt

A context table. This parameter, as well as the one in word_fsg.c should all go up to srch.c. They are more generic then the others.

◆ filler_backoff

backoff_t* srch_FLAT_FWD_graph_s::filler_backoff

Filler probability

◆ final_state

int32 srch_FLAT_FWD_graph_s::final_state

Final state is supposed to be the last state, so it is usually equal to n_state-1

◆ fwdDBG

fwd_dbg_t* srch_FLAT_FWD_graph_s::fwdDBG

Debug object of srch_flat_fwd.c

◆ hmmctx

hmm_context_t* srch_FLAT_FWD_graph_s::hmmctx

Structures for flat lexicon decoding search The HMM context.

◆ kbcore

kbcore_t* srch_FLAT_FWD_graph_s::kbcore

A pointer for convenience

◆ latfile_ext

char const* srch_FLAT_FWD_graph_s::latfile_ext

Complete word candidate filename for an utterance formed by word_cand_dir/<uttid>.latfile_ext

◆ lathist

latticehist_t* srch_FLAT_FWD_graph_s::lathist

Viterbi history (backpointer) table

◆ multiplex

int32 srch_FLAT_FWD_graph_s::multiplex

Whether we will use multiplexed triphones

◆ multiplex_singleph

int32 srch_FLAT_FWD_graph_s::multiplex_singleph

Whether we will use multiplexed triphones

◆ n_frm

int32 srch_FLAT_FWD_graph_s::n_frm

Number of frame of this utternance

◆ n_word_cand

int32 srch_FLAT_FWD_graph_s::n_word_cand

#candidate entries in word_cand for current utterance. If <= 0; full search performed for current utterance

◆ rcscore

int32* srch_FLAT_FWD_graph_s::rcscore

rc scores uncompacted; one entry/rc-ciphone

◆ renormalized

int32 srch_FLAT_FWD_graph_s::renormalized

Whether scores had to be renormalized in current utt

◆ tg_trans_done

uint8* srch_FLAT_FWD_graph_s::tg_trans_done

If tg_trans_done[w] TRUE, trigram transition to w occurred for a given history, and backoff bigram transition from same history should be avoided

◆ tm_hmmeval

ptmr_t srch_FLAT_FWD_graph_s::tm_hmmeval

◆ tm_hmmtrans

ptmr_t srch_FLAT_FWD_graph_s::tm_hmmtrans

◆ tm_wdtrans

ptmr_t srch_FLAT_FWD_graph_s::tm_wdtrans

◆ ug_backoff

backoff_t* srch_FLAT_FWD_graph_s::ug_backoff

Unigram backoff probability

◆ whmm

whmm_t** srch_FLAT_FWD_graph_s::whmm

The word hmms list. For actual search traverse

◆ word_cand

word_cand_t** srch_FLAT_FWD_graph_s::word_cand

Word candidates for each frame. (NOTE!! Another array with a hard limit on its size.)

◆ word_cand_cf

s3wid_t* srch_FLAT_FWD_graph_s::word_cand_cf

BAD_S3WID terminated array of candidate words for word transition in current frame (if using input word lattices to restrict search).

◆ word_cand_dir

char const* srch_FLAT_FWD_graph_s::word_cand_dir

Structures for decoding utterances subject to given input word lattices; ie, restricting the decoding to words found in the lattice. (For speeding up the decoding process.) NOTE: This mode is optional. If no input lattice is given, the entire vocabulary is eligible during recognition. Also, SILENCEWORD, FINISHWORD, and noisewords are always eligible candidates.

Input lattice specifies candidate words that may start at a given frame. In addition, this forward pass can also consider words starting at a number of neighbouring frames within a given window.

Input lattice file format: Each line contains a single <word> <startframe> info. The line may contain other info following these two fields; these are ignored. Empty lines and lines beginning with a # char in the first column (ie, comment lines) are ignored. Directory containing candidate words files. If NULL, full search performed for entire run

◆ word_cand_win

int32 srch_FLAT_FWD_graph_s::word_cand_win

In frame f, candidate words in input lattice from frames [(f - word_cand_win) .. (f + word_cand_win)] will be the actual candidates to be started(entered)

◆ word_ugprob

word_ugprob_t** srch_FLAT_FWD_graph_s::word_ugprob

word unigram probability
