Th.s paper explores the extent to which phoneme sequence constralnt'~ can be used to identify word boundaries in coutinnous speech recog~fition. The input consists of phonemic transcriptions (without word boundaries indicated) of 145 utterances produced by 1 ~e speaker. The constraints are derived by matching the complete set of 3 phonente sequences that can occur' across word boundaries to entries in large lexicons containing both citation and reduced h)rm pronunciations. Phonemic assimilatoxy adjushnents across word boundaries are alse taken into account. The results show that around 37% of all word boundaries can be correctly identified t rom a knowledge of.~uch phoneme sequence contraints alone, and ~hat this figure rises to 45% when a knowledge of one- and two-phoneme words and all le...
