Phonetic and Phonological Aspects of English Affricate Production in Children with Speech Disorders
-
William J. Hardcastle
Abstract
In this paper we consider phonetic and phonological aspects of the English voiceless affricate /t∫/ as it is realised by children with developmental speech disorders. The speakers described in the study have normal /t/ but disordered /∫/ and /t∫/. Using electropalatography (Reading EPG), we compare the stop and fricative phases of /t∫/ to independent /t/ and /∫/. This comparison shows that the place of articulation of /t∫/ can be predicted from that of independent /t/. There is a strict requirement for the affricate’s stop release to be homorganic with its fricative phase, irrespective of the place of articulation of independent /t/. Sometimes, there is also an observable coronal gesture during the stop phase of a dorsal affricate indicating the influence of independent /t/. This is predicted by phonological theories in which the affricate is related to both /t/ and /∫/ but not by theories in which the affricate is merely the stop counterpart to /∫/.
