Make a set of triphones by merging the currently loaded set of biphones. This is a very specialised command. All currently loaded HMMs must have 3 emitting states and be either left or right context-dependent biphones. The list of HMMs stored in triList should contain one or more triphones. For each triphone in triList of the form X-Y+Z, there must be currently loaded biphones X-Y and Y+Z. A new triphone X-Y+Z is then synthesised by first cloning Y+Z and then replacing the state information for the initial emitting state by the state information for the initial emitting state of X-Y. Note that the underlying physical names of the biphones used to create the triphones are recorded so that where possible, triphones generated from tied biphones are also tied. On completion, the new list of triphones including aliasses is written to the file newTriList.
