Five speech-language clinicians and 5 naive listeners rated the similarity of pairs of normal and dysphonic voices. Multidimensional scaling was used to determine the voice characteristics that were perceptually important for each voice set and listener group. Solution spaces were compared to determine if clinical experience affects perceptual strategies. Naive and expert listeners attended to different aspects of voice quality when judging the similarity of voices, for both normal and pathological voices. All naive listeners used similar perceptual strategies; however, individual clinicians differed substantially in the parameters they considered important when judging similarity. These differences were large enough to suggest that care must be taken when using data averaged across clinicians, because averaging obscures important aspects of an individual's perceptual behavior.
五名言语语言临床医生和五名普通听众对正常嗓音和发声障碍嗓音的成对相似度进行了评分。采用多维标度法来确定对于每组嗓音和听众群体而言在感知上重要的嗓音特征。对解决方案空间进行比较，以确定临床经验是否会影响感知策略。无论是正常嗓音还是病理性嗓音，普通听众和专业听众在判断嗓音相似度时关注的是嗓音质量的不同方面。所有普通听众都采用相似的感知策略；然而，个体临床医生在判断相似度时认为重要的参数却有很大差异。这些差异大到足以表明，在使用临床医生的数据平均值时必须谨慎，因为平均会掩盖个体感知行为的重要方面。
