The research presented here focuses on implementation and efficiency issues associated with the use of word graphs for interfacing acoustic speech recognition systems with natural language processing systems. The effectiveness of various pruning methods for graph construction is examined, as well as techniques for word graph compression. In addition, the word graph representation is compared to another predominant interface method, the N-best sentence list.
