Abstract

A path link passing speech recognition system and method for recognising input connected speech, the recognition system having a plurality of vocabulary nodes (24) associated with word representation models, at least one of the vocabulary nodes (24) of the network being able to process mono than one path link simultaneously, so allowing for more than one recognition result.
