The purpose of this study was to develop and test a training protocol for the perceptual evaluation of dysphonia. A group of 38 inexperienced listeners participated in a three-phase experiment: a pretest to evaluate their initial performance on categorization of dysphonic voices, a training phase, and a posttest to detect training-related changes in performance. In parallel, a different group of 14 listeners who were experts in voice assessment took a test that was identical to the posttest taken by the inexperienced subjects. The corpus used for the tests was made up of recordings of 142 voices of women reading aloud, with a sampling of voice qualities ranging from normal to severely degraded. The learners' performance on judgments of moderate and severe dysphonia improved between the pretest and the posttest. No improvement was observed for normal voices, whose initial detection was already good, nor for slight dysphonias, which appear to be the most difficult to learn. The improvements were still present on a delayed posttest taken a week later. Unexpectedly, the inexperienced listeners' initial performance was similar to that of the experts. After the training phase, their scores for severely deteriorated voices were even better than the experts'. In conclusion, our training protocol seems to be effective and could therefore be proposed to voice therapists. However, judging intermediate degrees of dysphonia remains fragile and therefore needs to be reinforced by repeated training.
本研究的目的是开发并测试一种用于嗓音障碍感知评估的训练方案。一组38名缺乏经验的听众参与了一项三阶段实验：一项预测试，以评估他们对嗓音障碍语音分类的初始表现；一个训练阶段；以及一项后测试，以检测与训练相关的表现变化。同时，另一组由14名嗓音评估专家组成的听众参加了一项测试，该测试与缺乏经验的受试者所进行的后测试相同。用于测试的语料库由142名女性大声朗读的语音录音组成，语音质量样本范围从正常到严重退化。学习者在中度和重度嗓音障碍判断上的表现，在预测试和后测试之间有所提高。对于初始检测就已经良好的正常嗓音，以及似乎最难识别的轻度嗓音障碍，均未观察到改善。在一周后进行的延迟后测试中，这些改善仍然存在。出乎意料的是，缺乏经验的听众的初始表现与专家的相似。在训练阶段之后，他们对严重恶化嗓音的评分甚至优于专家。总之，我们的训练方案似乎是有效的，因此可以推荐给嗓音治疗师。然而，判断嗓音障碍的中间程度仍然很薄弱，因此需要通过反复训练来加强。
