目的:本研究调查了听众的共识训练对感知语音分析的内部和中间可靠性和一致性的影响。使用这种培训,包括参考语音样本,可以假设使内存中的内部标准通用且更强大,这对于减少听觉感知等级的可变性非常重要。
方法:在培训前后进行测试的前瞻性设计。
方法:13名听力科学生担任听力科目。使用具有四点相等出现间隔量表的多维协议进行评级。刺激包括真实的呼吸困难患者的文本阅读。每个感知语音参数的一致性训练包括(1)定义,(2)基础生理学,(3)在三个不同年级中精心挑选的代表参数的声音例子,然后对感知特征进行小组讨论,和(4)实践练习,包括模仿,以利用听众的本体感受。
结果:Intrarater的可靠性和一致性显示间歇性失音的显着改善,而声带的改善则没有。在训练前,大多数参数的评分者间可靠性很高,训练后略有增加。评分者之间的协议显示,由于训练,大多数语音质量参数显着增加。
结论:结果支持特定共识培训的建议,包括使用参考语音样本材料,校准,均衡,并稳定听众记忆中的内部标准。
OBJECTIVE: This study investigates the effect of
consensus training of listeners on intrarater and interrater reliability and agreement of perceptual voice analysis. The use of such training, including a reference voice sample, could be assumed to make the internal standards held in memory common and more robust, which is of great importance to reduce the variability of auditory perceptual ratings.
METHODS: A prospective design with testing before and after training.
METHODS: Thirteen students of audiologopedics served as listening subjects. The ratings were made using a multidimensional protocol with four-point equal-appearing interval scales. The stimuli consisted of text reading by authentic dysphonic patients. The
consensus training for each perceptual voice parameter included (1) definition, (2) underlying physiology, (3) presentation of carefully selected sound examples representing the parameter in three different grades followed by group discussions of perceived characteristics, and (4) practical exercises including imitation to make use of the listeners\' proprioception.
RESULTS: Intrarater reliability and agreement showed a marked improvement for intermittent aphonia but not for vocal fry. Interrater reliability was high for most parameters before training with a slight increase after training. Interrater agreement showed marked increases for most voice quality parameters as a result of the training.
CONCLUSIONS: The results support the recommendation of specific
consensus training, including use of a reference voice sample material, to calibrate, equalize, and stabilize the internal standards held in memory by the listeners.
