Variables | |
| static int | bncnt |
| Count of basephone that can appear at the beginning of sentence. | |
| static int | edcnt |
| Count of basephone that can appear at the end of sentence. | |
| static HTK_HMM_INFO * | local_hmminfo |
| Local work area to hold HTK HMM data. | |
| static WORD_INFO * | local_winfo |
| Local work area to hold word dictionary. | |
| static APATNODE * | local_root |
| Local work area to hold basephone index root. | |
| static WORD_ID | current_w |
| Local work area to hold current word ID. | |
| static char | gbuf [MAX_HMMNAME_LEN] |
| Local work area for phone name handling. | |

These functions check whether all the possible triphones that may appear while recognition process is fully defined or mapped in HMM definition file and HMMList file.
Word dictionary is considered for the test. Only triphones that can appear as word-internal triphones and cross-word triphones on the given dictionary will be considered.
