Abstract
The recovery process of spoken language was investigated in twenty-three aphasics who had been under speech therapy for the period of eleven to fifty-eight months. SLTA was applied to all the subjects at three months post-onset and three more times at a three months interval. At the same time their severity of auditory comprehension and oral speech was evaluated with the Seven Graded Aphasia Scale (S. G. A. S.). The results were as follows. (l) While the severely impaired and the moderately impaired aphasics showed improvement, the mildly impaired aphasics did not change significantly. (2) According to the S. G. A. S., expressive ability showed more improvement in long term and significance than comprehensive ability. (3) Those who showed significant improvement in oral speech were all in their thirties or forties except one case.
