Function Documentation

static void add_to_error	(	WORD_INFO *	winfo,
		char *	name
	)			[static]

Add a triphone name to the missing error list in WORD_INFO.

Parameters:

	winfo	[i/o] word dictionary to add the error phone to error list
	name	[in] phone name to be added

Definition at line 56 of file voca_load_wordlist.c.

static void callback_list_error

(

void *

x

)

[static]

Traverse callback function to output a error phone.

Parameters:

x

[in] error phone string of the node

Definition at line 79 of file voca_load_wordlist.c.

static void list_error

(

WORD_INFO *

winfo

)

[static]

Output all error phones appeared while readin a word dictionary.

Parameters:

winfo

[in] word dictionary data

Definition at line 91 of file voca_load_wordlist.c.

boolean voca_load_word_line	(	char *	buf,
		WORD_INFO *	winfo,
		HTK_HMM_INFO *	hmminfo,
		char *	headphone,
		char *	tailphone,
		char *	contextphone
	)

Load a line from buffer and set parameters to the dictionary.

Parameters:

	buf	[in] input buffer containing a word entry
	winfo	[i/o] word dictionary to append the entry
	hmminfo	[in] phoneme HMM definition
	headphone	[in] word head silence model name
	tailphone	[in] word tail silence model name
	contextphone	[in] silence context name to be used at head and tail

Returns:

TRUE when successfully read, or FALSE on encountered end of dictionary. When an error occurs, this function will set winfo->ok_flag to FALSE.

Top function to read word list via text.

Parameters:

	fp	[in] file pointer
	winfo	[out] pointer to word dictionary to store the read data.

		boolean *	ok_flag,
		char *	headphone,
		char *	tailphone,
		char *	contextphone
	)

Sub function to Add a dictionary entry line to the word dictionary.

Parameters:

	buf	[i/o] buffer to hold the input string, will be modified in this function
	vnum_p	[in] current number of words in winfo
	linenum	[in] current line number of the input
	winfo	[out] pointer to word dictionary to append the data.
	hmminfo	[in] HTK HMM definition data. if NULL, phonemes are ignored.
	do_conv	[in] TRUE if performing triphone conversion
	ok_flag	[out] will be set to FALSE if an error occured for this input.
	headphone	[in] word head silence model name
	tailphone	[in] word tail silence model name
	contextphone	[in] silence context name to be used at head and tail

Returns:

FALSE if buf == "DICEND", else TRUE will be returned.
