Use a set of decision trees to create a new set of models specified by the hmmList. The decision trees may be made as a result of either the TB or LT command.
Each model in hmmList is constructed in the following manner. If a model with the same logical name already exists in the current HMM set this is used unchanged, otherwise the model is synthesised from the decision trees. If the trees cluster at the model level the synthesis results in a logical model sharing the physical model from the tree that matches the new context. If the clustering was performed at the state level a prototype model (an example of the same phone model occurring in a different context) is found and a new HMM is constructed that shares the transition matrix with the prototype model but consists of tied states selected using the decision tree.
