Function Documentation

void param_init_content

(

HTK_Param *

p

)

Initialize the content of the parameter data.

Parameters:

p

[out] parameter data

Definition at line 35 of file param_malloc.c.

Referenced by new_param(), param_free_content(), and wav2mfcc().

boolean param_alloc	(	HTK_Param *	p,
		unsigned int	samplenum,
		short	veclen
	)

Allocate vector area for required length and frames.

Allocate memory if not yet, or expand it if already allocated but not sufficient. If sufficient amount is already allocated, do nothing. The allocation are updated by HTK_PARAM_INCREMENT_STEP_FRAME step to avoid numerous re-allocation

Parameters:

	p	[i/o] parameter data
	samplenum	[in] required number of frames
	veclen	[in] required length of vector

Returns:

TRUE on success, FALSE on failure.

void param_free_content

(

HTK_Param *

p

)

Free and clear the content of the parameter data.

Parameters:

p

[out] parameter data

Definition at line 106 of file param_malloc.c.

HTK_Param* new_param

(

)

Allocate a new parameter.

Returns:

pointer to the newly allocated area.

void free_param

(

HTK_Param *

pinfo

)

Free the HTK parameter structure.

Parameters:

pinfo

[in] parameter data to be destroyed.
