関数

static GCODEBOOK* codebook_lookup	(	HTK_HMM_INFO *	hmm,
		char *	keyname
	)		[static]

Look up a data macro by the name.

引数:

hmm	[in] HMM definition data
keyname	[in] macro name to find

戻り値:

pointer to the found data, or NULL if not found.

void codebook_add	(	HTK_HMM_INFO *	hmm,
		GCODEBOOK *	new
	)

Add a new data to the global structure.

引数:

hmm	[i/o] HMM definition data to store it
new	[in] new data to be added

static void tmix_create_codebook_index	(	HTK_HMM_INFO *	hmminfo,
		GCODEBOOK *	book
	)		[static]

Convert codebook ID to the defined HMM density.

This function assigns a list of HMM density definition to the given codebook. The densities are searched by the name of codebook name followed by the mixture component ID starting from 1. For example, if you have a codebook whose name is "ny4s2m", The densities of names like "ny4s2m1", "ny4s2m2", ... will be searched through the HMM definition data. The resulting list will be stored in the codebook.

If some density definitions are not found, they are just skipped. In this case, a warning message will be output to standard error.

引数:

hmminfo	[in] HMM definition data that has densities
book	[i/o] codebook, name given and density list will be stored.

void tmix_read	(	FILE *	fp,
		HTK_HMM_PDF *	mpdf,
		HTK_HMM_INFO *	hmm
	)

Read a codebook name and weights, build the codebook structure on demand, and assigns them to the current mixture PDF.

The required codebook on the current token will be assigned to this mpdf. If the corresponding codebook structure is not built yet, it will be constructed here on demand by gathering corresponding mixture density definitions. Then this mpdf will store the pointer to the codebook, together with its own mixture weights in the following tokens.

引数:

fp	[in] file pointer
mpdf	[i/o] current HMM mixture PDF to hold pointer to the codebook and their weights
hmm	[i/o] HMM definition data, codebook statistics and tied-mixture marker will be modified.
