説明

HTKのHMMを格納するためのデータ構造定義

データ構造はモデル・状態からガウス分布の平均・分散まで各レベルごとに 定義されています．各レベルはおおよそ HTK のマクロ定義に対応しています． 各データは, 下位のデータ構造へのポインタ および同レベルの構造体同士のリンクリストを保持しています．

マクロ定義

#define MAX_STATE_NUM   2147483647

Possible maximum value of state ID (in unsigned short)

htk_hmm.h の 71 行で定義されています。

参照元 rdhmmdef().

#define HMM_RC_DLIM   "+"

Delimiter strings/characters to generate logical triphone names.

Right context delimiter in string

列挙型

enum iwcd_type

Specify method of calculating approximated acoustic score at inter-word context pseudo phones on word edge.

列挙型の値:

IWCD_UNDEF	not specified explicitly
IWCD_MAX	Use maximum score among context variants.
IWCD_AVG	Use average score among context variants.
IWCD_NBEST	Use average of N-best scores among context variants.

htk_hmm.h の 86 行で定義されています。
