청지각적 평가 방식에 따른 음성장애 심한 정도 판단과 자가 신뢰도에 대한 차이

The purpose of this study was to investigate the effect of two different auditory-perceptual evaluations on listeners’ judgement and confidence rating on dysphonic speakers. 7-point interval scale(EAI) and VAS(visual analogue scale) were used to evaluate voice severity, And 7-point rating scale was used for the confidence rating of listeners’ self-scores on perceptual judgement. These methods were performed within the anchored (condition 1)and non-anchored scales (conditions 2) in vowel prolongation and reading tasks by 20 dysphonic speakers. 30 undergraduate students studying communication disorder were enrolled to the perceptual evaluation. The results showed that the scores of VAS was significantly higher than EAI in both conditions. In confidence ratings, EAI was higher than VAS in phonation task(condition 1), and in reading task(condition 2), but these results were not significantly different.
