Abstract
In this study, we examine how fast decoding of conversational speech with large vocabularies pro ts from ecient use of linguistic information, i.e. language models and grammars. Based on a re-entrant single pronunciation pre x tree, we use the concept of linguistic context polymorphism to allow an early incorporation of language model information. This approach allows us to use all available language model information in a one-pass decoder, using the same engine to decode with statistical n-gram language models as well as context free grammars or re-scoring of lattices in an ecient way.
