These function is for searching HMM definition from phone name like "g-u+i".
The result is pointer to the corresponding logical HMM (HMM_Logical). The logical HMM holds either pointer to an actual HMM data defined in HTK HMM definition, or pointer to a pseudo HMM set when the query name is biphone or monophone and they are not defined in either HTK HMM definition or HMMList mapping file.
Adding physical HMM defined in HTK HMM definitions and pseudo phones to the logical HMM mapping function is also done here.

| static void hmm_count_logical_num | ( | HTK_HMM_INFO * | hmminfo | ) | [static] |

| void hmm_add_physical_to_logical | ( | HTK_HMM_INFO * | hmminfo | ) |
Add all physical HMM to logical HMM.
This function should be called only if HMMList is not specified. Julius assumes all the triphones should be explicitly mapped using HMMList file.

| static boolean hmm_add_pseudo_phones_sub | ( | HTK_HMM_INFO * | hmminfo, | |
| char * | name | |||
| ) | [static] |
Add a pseudo monophone and pseudo biphone to logical HMM.
Logical HMM specified in HMMlist precedes pseudo HMM: if some monophones or biphones are already defined in HMMList, pseudo HMM will not be added.
