A popular heuristic technique for pronunciation modelling extends the lexicon with pronunciations for selected word phrases or multiword units in order to capture limited cross-word pronunciation effects without significantly increasing acoustic confusability or computational requirements. This paper describes methods for selecting a set of multiwords and for learning alternative pronunciations which are more representative of those found in fluent speech. The methods are evaluated on the Switchboard spontaneous speech task.
