Function Documentation

static int totalstatelen (  HMM_Logical **  hdseq, int  hdseqlen )  [static]

Calculate total number of states in a phoneme sequence. Parameters: hdseq  [in] phoneme sequence as given by pointer list of logical HMM hdseqlen  [in] length of above Returns: the total number of states in the sequence. Definition at line 41 of file mkwhmm.c. Referenced by new_make_word_hmm_with_lm().

static void add_arc (  HMM_STATE *  state, int  arc, LOGPROB  a )  [static]

Add a transition arc on the HMM state. Parameters: state  [out] HMM state to add the arc arc  [in] state id of destination a  [in] transition log probability Definition at line 74 of file mkwhmm.c. Referenced by new_make_word_hmm_with_lm().

HMM* new_make_word_hmm_with_lm (  HTK_HMM_INFO *  hmminfo, HMM_Logical **  hdseq, int  hdseqlen, LOGPROB *  lscore )

Make a HMM instance for recognition from phoneme sequence, with connection probabiliry given for each phoneme. Parameters: hmminfo  [in] HTK HMM definitions data hdseq  [in] phoneme sequence as given by pointer list of logical HMM hdseqlen  [in] length of above lscore  [in] list of log probability to be added at the emitting transition of each phoneme, or NULL if not needed. Returns: newly allocated HMM instance generated from the given data. Definition at line 102 of file mkwhmm.c. Referenced by new_make_word_hmm().

HMM* new_make_word_hmm (  HTK_HMM_INFO *  hmminfo, HMM_Logical **  hdseq, int  hdseqlen )

Make a HMM instance for recognition from phoneme sequence. Parameters: hmminfo  [in] HTK HMM definitions data hdseq  [in] phoneme sequence as given by pointer list of logical HMM hdseqlen  [in] length of above Returns: newly allocated HMM instance generated from the given data. Definition at line 362 of file mkwhmm.c. Referenced by do_align(), and scan_word().

void free_hmm (  HMM *  d  )

Free an HMM instance. Parameters: d  [in] HMM instance to free Definition at line 381 of file mkwhmm.c. Referenced by do_align().
