Simple networks constructed from the sequence of acoustic units A, B and C. The undirected binary network (left) simply indicates that A, B, and C are associated with one another without any information about transition direction. The directed binary network (centre) adds ordering information, for example that C cannot follow A. The weighted directed network (right) show the probabilities of the transitions between units based on a bigram model.
