説明

The communicable abilities of patients with dysarthria following cerebral apoplexy were mostly represented by their speech intelligibility measured by articulation tests. The relationships between the speech intelligibility and the movement of paralytic articulatory organs were studied.The tendencies of misspeaking of apoplexic patients were analyzed by auditory and physical methods. Consequently, the incomplete postnasal obstruction method was taken up improve the speech intelligibility of the patients with paralytic dysarthria. The results obtained were as follows:<br>1. There were close relationships between the speech intelligibility and the paralytic movements of the articulatory organs of apoplexic patients.<br>2. The patients with mild paralytic articulation disorders had minor disorders of soft palatal sounds, but speech disorders in vocal frictional and explosive sounds were remarkable.<br>3. Regardless of the degree of articulation disorders, they had high speech intelligibility of vowels and glottal sounds.<br>4. The patients with serious paralytic articulation disorders misspoke characteristically. They had less misspeaking in the vowels which were the part of some syllables, but they had strong tendencies of misspeaking the consonants just like glottal sound and nasal sound. For example, in the sound of "ka", they could correctly pronounce "a" part, but "k" sound was pronounced like "h" sound.<br>5. The analysis of misspeaking sounds by the sonagram showed the disappearance of spike fill of explossive consonants, but the remarkable increase in extraresonance and interfilling due to nasalization of vowels was seen.<br>6. The speech of the patients with paralytic dysarthria who had not been treated successfully was improved by the incomplete postnasal obstruction method
