The study investigated the effect of immediate feedback in training listeners to perceive subtle differences in voice quality, a perceptual skill that is important for speech-language pathologists. Sixty naive listeners were randomly assigned to a feedback group (Group F), a no feedback group (Group NF), and a no training group acting as a control group (Group C). The task was to evaluate the severity of a perceptual voice quality (breathiness) by using a reference-matching paradigm. All participants took part in three rating sessions (pre-training, 2 days after training and 1 week after training). Group F and Group NF participated in a training session immediately after the first rating session, where Group F practiced with immediate feedback given and Group NF practice with no immediate feedback given. The results showed that Group F and Group NF had significant improvement after training, but Group F did not retain the improvement in the third rating session. The use of a reference-matching training paradigm without giving frequent immediate feedback is suggested for auditory-perceptual voice evaluation training. The most effective frequency of immediate feedback is yet to be determined.
该研究调查了即时反馈在训练听众感知嗓音质量细微差异方面的效果，这是一种对言语语言病理学家很重要的感知技能。60名未经训练的听众被随机分为反馈组（F组）、无反馈组（NF组）和作为对照组的无训练组（C组）。任务是使用参考匹配范式评估感知嗓音质量（呼吸声）的严重程度。所有参与者都参加了三次评分环节（训练前、训练后2天和训练后1周）。F组和NF组在第一次评分环节后立即参加了一次训练环节，其中F组在有即时反馈的情况下进行练习，NF组在没有即时反馈的情况下进行练习。结果显示，F组和NF组在训练后有显著改善，但F组在第三次评分环节中没有保持这种改善。建议在听觉感知嗓音评估训练中使用不频繁给予即时反馈的参考匹配训练范式。即时反馈的最有效频率还有待确定。
