Detailed Description

Implementation of dict2pid.

A general remark, notice "comsseq" sometimes means compressed sequence. It should be understood as differnet thing as composite in the source code.

Function Documentation

compress_table()

void compress_table	(	s3ssid_t *	uncomp_tab,
		s3ssid_t *	com_tab,
		s3cipid_t *	ci_map,
		int32	n_ci
	)

Compress this map

References BAD_S3CIPID, and BAD_S3SSID.

dict2pid_build()

dict2pid_t* dict2pid_build	(	mdef_t *	mdef,
		dict_t *	dict,
		int32	is_composite,
		logmath_t *	logmath
	)

Build the dict2pid structure for the given model/dictionary

This segments of code take care of the initialization of internal[0] and ldiph[b][r][l]

This part will take care of the initialization of internal[pronlen-1] and rdiph[b][l][r]. Notice that this is symmetric to the first part of the code.

Parameters

mdef	A model definition
dict	An initialized dictionary
is_composite	Whether composite triphones will be built

dict2pid_comsenscr()

void dict2pid_comsenscr	(	dict2pid_t *	d2p,
		int32 *	senscr,
		int32 *	comsenscr
	)

Populate composite senone score array.

The composite senone score is the maximum of its component senones' scores, scaled down by the number of component senones.

Parameters

d2p	In: a dict2pid_t structure
senscr	In: Ordinary senone scores
comsenscr	Out: Composite senone scores

dict2pid_comsseq2sen_active()

void dict2pid_comsseq2sen_active	(	dict2pid_t *	d2p,
		mdef_t *	mdef,
		uint8 *	comssid,
		uint8 *	sen
	)

Mark senones active based on a set of active composite senones.

Parameters

d2p	In: a dict2pid_t structure
mdef	In: a mdef_t structure
comssid	In: Active flag for each comssid
sen	In/Out: Active flags set for senones indicated by the active comssid

dict2pid_dump()

void dict2pid_dump	(	FILE *	fp,
		dict2pid_t *	d2p,
		mdef_t *	mdef,
		dict_t *	dict
	)

For debugging

Parameters

fp	In: a file pointer
d2p	In: a dict2pid_t structure
mdef	In: a mdef_t structure
dict	In: a dictionary structure

dict2pid_free()

void dict2pid_free

(

dict2pid_t *

d2p

)

Free the memory dict2pid structure

Parameters

d2p	In: the d2p

dict2pid_get_rcmap()

s3cipid_t* dict2pid_get_rcmap	(	dict2pid_t *	d2p,
		s3wid_t	w,
		dict_t *	dict
	)

Get RC map

Parameters

d2p	In: a dict2pid
w	In: a wid
dict	In: a dictionary

dict2pid_report()

void dict2pid_report

(

dict2pid_t *

d2p

)

Report a dict2pid data structure

Parameters

d2p	In: a dict2pid_t structure

get_rc_nssid()

int32 get_rc_nssid	(	dict2pid_t *	d2p,
		s3wid_t	w,
		dict_t *	dict
	)

ARCHAN, A duplicate of get_rc_npid in ctxt_table.h. I doubt whether it is correct because the compressed map has not been checked.

Parameters

d2p	In: a dict2pid
w	In: a wid
dict	In: a dictionary
