EPG and Acoustic Study of Some Connected Speech Processes

William J. Hardcastle

Queen Margaret College, Edinburgh, UK

Simultaneous EPG, acoustic, aerodynamic and electroglottographic data were obtained for 5 repetitions of a test sentence 'Fred can go, Susan can't go and Linda is uncertain' spoken by 7 native English speakers at normal conversational rate. Seven different types of EPG patterns were found to characterise the alveolarvelar consonant sequences in the sentences ranging from fully assimilated (no evidence of alveolar contact) to fully unassimilated (with audible alveolar release). There was considerable inter- and intra-subject variability in the production of the consonant sequences. The alveolar nasals seem more susceptible to assimilation than the plosive. A number of connected speech processes were also identified including vowel elision, glottalisation and nasalisation on vowels.
