Function Documentation

static int totalstatelen	(	HMM_Logical **	hdseq,
		int	hdseqlen,
		boolean *	has_sp,
		HTK_HMM_INFO *	hmminfo
	)			[static]

Calculate total number of states in a phoneme sequence.

Parameters:

	hdseq	[in] phoneme sequence as given by pointer list of logical HMM
	hdseqlen	[in] length of above
	has_sp	[in] indicates where short-pause insertion is possible
	hmminfo	[in] HMM definition

Returns:

the total number of states in the sequence.

static void add_arc	(	HMM_STATE *	state,
		int	arc,
		LOGPROB	a
	)			[static]

Add a transition arc on the HMM state.

Parameters:

	state	[out] HMM state to add the arc
	arc	[in] state id of destination
	a	[in] transition log probability

		HMM_Logical **	hdseq,
		int	hdseqlen,
		boolean *	has_sp,
		LOGPROB *	lscore
	)

Make a HMM instance for recognition from phoneme sequence, with connection probabiliry given for each phoneme.

Parameters:

	hmminfo	[in] HTK HMM definitions data
	hdseq	[in] phoneme sequence as given by pointer list of logical HMM
	hdseqlen	[in] length of above
	has_sp	[in] indicates where short-pause insertion is possible
	lscore	[in] list of log probability to be added at the emitting transition of each phoneme, or NULL if not needed.

Returns:

newly allocated HMM instance generated from the given data.
