This structure will be used to handle cross-word triphone on the 1st pass. At a triphone HMM at the edge of a word in the tree lexicon, the state nodes should have a set of HMM states with the same base phone of all triphones at the same location instead of a single state information. This context-dependent HMM set for cross-word triphone is also called as "pseudo" phone in Julius.
When computing the 1st pass, the maximum (or average or N-best average) value from the likelihoods of state set will be taken as the output probability of the states instead of the actual cross-word triphone.
This approximated value will be fixed by re-computation on the 2nd pass.
