説明

HMMと入力特徴パラメータの型をチェックします．タイプが一致しない場合，特徴パラメータの一部を削除することで一致するよう調整できるかどうかを試みます．（例：特徴量ファイルが MFCC_E_D_Z (26次元) で与えられたとき，音響モデルが MFCC_E_D_N_Z (25次元) である場合，絶対値パワー項を差し引くことで調整できます．）

	)			`[static]`

Put exlusion marks for vector for len elements from loc -th dimension.

引数:

	loc	[in] beginning dimension to mark
	len	[in] number of dimension to mark from loc
	vmark	[in] mark buffer
	vlen	[in] length of vmark

static void exec_exclude_vectors	(	HTK_Param *	p,
		int *	vmark
	)			`[static]`

Execute exclusion for a parameter data according to the exclusion marks.

Execute vector element exclusion will be done inline.

引数:

	p	[i/o] parameter
	vmark	[in] mark buffer

int guess_basenum	(	HTK_Param *	p,
		short	qualtype
	)

Guess the length of the base coefficient according to the total vector length and parameter type.

引数:

	p	[in] parameter data
	qualtype	[in] parameter type

戻り値:: the guessed size of the base coefficient.

		short	dst_type_arg,
		int *	vmark,
		int	vlen,
		short *	new_type
	)			`[static]`

Compare source parameter type and required type in HTK HMM, and set mark.

引数:

	src	[in] input parameter
	dst_type_arg	[in] required parameter type
	vmark	[in] mark buffer
	vlen	[in] length of vmark
	new_type	[out] return the new type

戻り値:: TRUE on success, FALSE on failure.

参照元 select_param_kind().

static boolean select_param_kind	(	HTK_Param *	p,
		short	dst_type_arg
	)			`[static]`

Extracts needed parameter vector specified in dst_type_arg from src, and returns newly allocated parameter structure.

引数:

	src	[in] input parameter
	dst_type_arg	[in] required parameter type

戻り値:: newly allocated adjusted parameter, NULL on failure.

参照元 param_check_and_adjust().

int param_check_and_adjust	(	HTK_HMM_INFO *	hmminfo,
		HTK_Param *	param,
		boolean	vflag
	)

Top function to adjust parameter.

It compares the types for the given parameter param and HMM definition hmminfo. If type is not the same, adjustment will be tried.

引数:

	hmminfo	[in] HTK HMM definition
	param	[i/o] input parameter, will be freed if adjustment was performed in this function
	vflag	[in] if TRUE, output verbose messages

戻り値:: 1 on success, 0 if no adjustment needed, or -1 on failure (in case parameter type does not match even by the adjustment).
