関数

void add_right_context	(	char	name[],
		char *	rc
	)

Generate context-dependent phone name from base phone name and its right context phone name.

The center phone name of the right context name will be appended to the base phone name. If the phone name already has right context, it will be renamed to the new one.

• Example 1: "a" | "r" -> "a+r"
• Example 2: "a" | "e-k+i" -> "a+k"
• Example 3: "k-a" | "e" -> "k-a+e"
• Example 4: "k-a+e" | "b" -> "k-a+b"
• Example 5: "k-a+e" | "r-u+k" -> "k-a+u"

引数:

	name	[i/o] string of phone name to be the base name (will be modified)
	rc	[in] right context phone name

void add_left_context	(	char	name[],
		char *	lc
	)

Generate context-dependent phone name from base phone name and its left context phone name.

The center phone name of the left context name will be appended to the base phone name. If the phone name already has left context, it will be renamed to the new one.

引数:

	name	[i/o] string of phone name to be the base name (will be modified)
	lc	[in] left context phone name

HMM_Logical* get_right_context_HMM	(	HMM_Logical *	base,
		char *	rc_name,
		HTK_HMM_INFO *	hmminfo
	)

Search for right context HMM in logical HMM

The name of a new right context HMM, given base phone HMM and a right context phone string, will be generated, and search it in the list of logical HMM. If found, return the pointer to the logical HMM.

引数:

	base	[in] base phone HMM
	rc_name	[in] right context phone name (allow context-dependent name)
	hmminfo	[in] HTK HMM definition data

戻り値:

the pointer to the logical HMM, or NULL if not found.

HMM_Logical* get_left_context_HMM	(	HMM_Logical *	base,
		char *	lc_name,
		HTK_HMM_INFO *	hmminfo
	)

Search for left context HMM in logical HMM

The name of a new left context HMM, given base phone HMM and a left context phone string, will be generated, and search it in the list of logical HMM. If found, return the pointer to the logical HMM.

引数:

	base	[in] base phone HMM
	lc_name	[in] left context phone name (allow context-dependent name)
	hmminfo	[in] HTK HMM definition data

戻り値:

the pointer to the logical HMM, or NULL if not found.

char* center_name	(	char *	hmmname,
		char *	buf
	)

Extract the center phone name and copy to the specified buffer.

引数:

	hmmname	[in] string from which the center phone name will be extracted
	buf	[out] the extracted phone name will be written here

戻り値:

the argument buf.

char* leftcenter_name	(	char *	hmmname,
		char *	buf
	)

Return "left - center" phone name, modifying buf.

引数:

	hmmname	[in] context-dependent phone name string
	buf	[out] resulting phone name

戻り値:

the argument buf.

	)

Return "center + right" phone name, modifying buf.

引数:
