Detailed Description

Read HTK HMM definition file: the main.

This file includes the main routine to read the HMM definition file in HTK format.

This file also contains functions and global variables for per-token reading tailored for reading HTK HMM definition file. The read_token() will read the file per token, and the read token is stored in a global variable rdhmmdef_token. The other reading function will refer to this variable to read the current token.

void rderr (  char *  str  )

Output error message, with current reading status. Parameters: str  [in] error string Definition at line 60 of file rdhmmdef.c.

char* read_token (  FILE *  fp  )

Read next token and ste it to rdhmmdef_token. Parameters: fp  [in] file pointer Returns: the pointer to the read token, or NULL on end of file or error. Definition at line 77 of file rdhmmdef.c. Referenced by dens_read(), get_dens_data(), get_state_data(), get_trans_data(), get_var_data(), htk_hmmdata_read(), rdhmmdef(), read_global_opt(), regtree_read(), state_read(), tmix_read(), trans_read(), and var_read().

static void conv_log_arc (  HTK_HMM_INFO *  hmm  )  [static]

Convert all the transition probabilities to log10 scale. Parameters: hmm  [i/o] HMM definition data to modify. Definition at line 106 of file rdhmmdef.c. Referenced by rdhmmdef().

void init_hmm (  HTK_HMM_INFO *  hmm  )

Initialize the HMM definition data by setting default values. Parameters: hmm  [i/o] HMM definition data to initialize. Definition at line 129 of file rdhmmdef.c. Referenced by rdhmmdef().

boolean rdhmmdef (  FILE *  fp, HTK_HMM_INFO *  hmm )

Main top routine to read in HTK HMM definition file. A HTK HMM definition file will be read from fp. After reading, the parameter type is checked and calculate some statistics. Parameters: fp  [in] file pointer hmm  [out] pointer to a HMM definition structure to store data. Returns: TRUE on success, FALSE on failure. Definition at line 174 of file rdhmmdef.c. Referenced by init_hmminfo().
