In this paper, the incorporation of path merging within BT's dynamic speech recognition architecture is discussed. One of the disadvantages of dynamic network generation is the size of the network generated. This is to a large extent due to the creation of many duplicate network portions. The use of a path merging strategy can redress this problem to some extent. This paper discusses the theory behind path merging, demonstrating a 22% speed improvement on a typical recognition task for no loss in top-N accuracy.
