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 Definition at line 60 of file m_chkparam.c. Referenced by check_specs().

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. Definition at line 87 of file m_chkparam.c. Referenced by main().

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. Definition at line 218 of file m_chkparam.c. Referenced by set_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. Definition at line 283 of file m_chkparam.c. Referenced by final_fusion().

void set_lm_weight (   )

Set default values of LM weight and word insertion penalty on the 1st pass depending on the acoustic model type. Definition at line 318 of file m_chkparam.c. Referenced by configure_param().

void set_lm_weight2 (   )

Set default values of LM weight and word insertion penalty on the 2nd pass depending on the acoustic model type. Definition at line 342 of file m_chkparam.c. Referenced by configure_param().
