ABSTRACT

The purpose of this study was to examine the effects of the computerized perceptual training program for improvement of the ability to evaluate voice quality. For such purpose, the experiment was performed for evaluating the reliability and accuracy for R, B, S rating of pathological voice samples. 40 college students participated in the experiment. A half of them were allocated in the experimental group with the perceptual training program including three steps according to the difficulty, other half of them allocated in the control group without the perceptual training program. The pre-test and post-test to rate R, B, S scale were taken before and after the perceptual training program. The findings of this study showed that the reliability and accuracy of R, B, S scales rating of experimental group after the perceptual training program were significantly improved than before that program. However the reliability and accuracy of the control group were not improved. The results suggested that the perceptual training program is effective for improvement of the ability to evaluate voice quality. In final section, the guidelines for the effective perceptual training system design and the follow-up researches were discussed.
