Pointer to corresponding output state definition
When a triphone model is used, if this state is located as a part of phoneme HMM on word-edge, the corresponding pseudo-triphone, i.e. "*-e+g", "k-a+*", should be assigned. Otherwise, i.e. if this state is located at internal position of a word, pointer to the corresponding physical (actually defined) HMM will be assigned. When a triphone model is used, phoneme HMMs on word-edge should be pseudo-triphone, i.e. "*-e+g", "k-a+*". In this case, the belonging state should hold the output probability function in CD_State_Set. Otherwise, i.e. if this state is located at internal position of a word, pointer to the corresponding physical (actually defined) HMM will be assigned.
