Abstract

|
|
Motor aphasia is an affection frequently caused by insult of the left middle cerebral artery and usually accompanied by a large lesion involving the Broca´s area and the adjacent motor and premotor areas. Therefore, a patient with motor aphasia commonly shows articulatory disturbances due to failure of the motor programing of speech sound. Objective assessment and treatment of phonologic programing is one of the important aspects of speech therapy in aphasic patients. We analyzed the speech disorders accompanied with motor aphasia in a 45-years-old man using a computerized sound spectrograph, Visi-Pitch^®, and Multi-Dimensional Voice Program^®. We concluded that a computerized speech analysis system is a useful took to visualize and quantitatively analyse the severity and progression of dysarthria, and the effect of speech therapy.
