Contribution of Articulatory/Resonatory Dysfunction to Speech Disorders
Speech disorders related to articulatory/resonatory dysfunction include disorders that result from impairment in any component of the articulatory/resonatory system, and as such are quite comprehensive.
They include all motor speech disorders, including dysarthria and apraxia (Table 4.4), as well as disorders resulting from congenital conditions such as cleft palate.Although the three components of speech described previously are considered separately as individual components, they function as a single coordinated and interactive unit for production of speech, and as such, are subsystems of a complex motor act requiring precise coordination of muscle groups. It is easy to understand how impairments in any of these components can have an impact on communication, as the extent and complexity of the speech system make it susceptible to the influence of a myriad of factors.
