Abstract
|
|
|
|
The purpose of this study was to identify the acoustic properties of 9 word initial Korean plosives in the speech of adults with cerebral palsy. Normal adults and two groups of adults with cerebral palsy (athetoid group and spastic group) participated in this study. Speech material included monosyllabic CVC real word pairs. Among the various acoustic properties of plosives, the aspiration duration was measured. Adults with cerebral palsy exhibited different patterns of aspiration duration for triplets of Korean plosives compared to normal adults. In addition, the plosive production of spastick group was distinguished from that of athetoid group. Such acoustic characteristics of plosives of adults with cerebral palsy may negatively affect the intelligibility of their speech.
