SPEECH MOTOR SKILLS IN CHILDREN WHO STUTTER

Summary/Abstract: Speech performance could be the result of either the capacity of the system itself and/or the speech skills which have been learned over a period of time. Skills concept is considered as a fundamental characteristic of motor production whose development can be seen as a continuum covering stages from cognitive stages to an automatic performance. Results of different studies have revealed that individuals who stutter differ from persons with normal speech production regarding the kinematic, orofacial nonspeech and speech tasks. Such results lead us to have doubts that individuals who stutter are more toward the weak margin of the speech motor skill continuum and that there is dysfunction within the cortical and subcortical areas of the motor control system that does not relate to speech motor behavior alone. The purpose of this investigation was to explore speech motor skills in children who stutter and to find out if there is a correlation between motor speech tasks and duration of stuttering on one hand and the subtests of Riley Instrument for stuttering severity on the other. Results showed that children who stutter achieved poorer results regarding speech-motor control (diadochokinesis) than control group. There were not statistically significant difference between groups on F2 transition and voice tremor variables.
