Function Documentation

void init_dfa	(	DFA_INFO *	dinfo,
		char *	filename
	)

Read in a grammar file and set to DFA grammar structure

Parameters:

	dinfo	[i/o] a blank DFA data
	filename	[in] DFA grammar file name

Definition at line 45 of file init_dfa.c.

void make_dfa_voca_ref	(	DFA_INFO *	dinfo,
		WORD_INFO *	winfo
	)

Make correspondence between all words in dictionary and categories in grammar, both from a word to a category and from a category to words.

Parameters:

	dinfo	[i/o] DFA grammar, category information will be built here.
	winfo	[i/o] Word dictionary, word-to-category information will be build here.

void dfa_find_pause_word	(	DFA_INFO *	dfa,
		WORD_INFO *	winfo,
		HTK_HMM_INFO *	hmminfo
	)

Find pause word and pause category information, and set to the grammar data.

Parameters:

	dfa	[i/o] DFA grammar, sp_id and is_sp will be built here.
	winfo	[in] Word dictionary
	hmminfo	[in] HTK HMM to provide which is short pause HMM

void dfa_pause_word_append	(	DFA_INFO *	dst,
		DFA_INFO *	src,
		int	coffset
	)

Append the pause word/category information at the last.

Parameters:

	dst	[i/o] DFA grammar
	src	[in] DFA grammar to be appended to dst
	coffset	appending category point in dst
