title: Effect on phoneme duration control of three utterance-length conditions in an apractic patient.
abstract: Phoneme duration control in utterances of various lengths was investigated in one apractic subject. Results indicate a loss of segment duration control and a speeding of intrasyllabic articulatory rates in apraxia. Findings are related to a theory of apractic speech dysfunction.
