Function Documentation

void checkpath

(

char *

filename

)

Check if a file actually exist and is readable.

Parameters:

filename

[in] file path name

Definition at line 39 of file m_chkparam.c.

Referenced by check_specs().

static void checkdir

(

char *

dirname

)

[static]

Check if a directory exists and is writable.

Parameters:

dirname

[in] directory path name

void check_specs

(

)

Check the user-specified parameters.

This functions checks whether the specified files actually exist, and also the mutual coherence of the parameters and their correspondence with used model is also checked. If a serious error is found, it produces error and exits.

static int default_width

(

)

[static]

Returns the pre-defined default beam width on 1st pass of beam search.

The default beam width will be selected from the pre-defined values according to the compilation-time engine setting and the type of acoustic model. The pre-defined values were determined from the development experiments on IPA evaluation testset of Japanese 20k-word dictation task.

Returns:

the selected default beam width.

int set_beam_width	(	WCHMM_INFO *	wchmm,
		int	specified
	)

Determine beam width on the 1st pass.

Parameters:

	wchmm	[in] tree lexicon data
	specified	[in] user-specified beam width (0: full search, -1: not specified)

Returns:

the final beam width to be used.

void set_lm_weight

(

)

Set default values of LM weight and word insertion penalty on the 1st pass depending on the acoustic model type.

void set_lm_weight2

(

)

Set default values of LM weight and word insertion penalty on the 2nd pass depending on the acoustic model type.
