This investigation attempted to identify listener strategies or perceptual modes that might be adopted by hearing-impaired listeners when making similarity judgments among pairs of speech sounds. Further, an attempt was made to describe the relationship between similarity judgments and auditory confusions for such listeners. Subjects provided similarity ratings and recognition responses to consonant pairs. The resulting similarity judgments were organized into a variety of similarity matrices and analyzed via multidimensional scaling and hierarchical clustering, as well as by traditional descriptive and interpretative statistics. The analyses of the similarity ratings between consonants showed that hearing-impaired listeners apply phonemic labels to the stimuli and base their ratings on these labels rather than on the unlabeled acoustic characteristics of the speech sounds. Analysis of the recognition data indicated that those consonants which are most confused are not necessarily the most conceptually similar to the listener.
本研究试图确定听力受损的听众在对语音对进行相似性判断时可能采用的听力策略或感知模式。此外，还尝试描述此类听众的相似性判断与听觉混淆之间的关系。受试者对辅音对提供相似性评分和识别反应。所得的相似性判断被整理成各种相似性矩阵，并通过多维尺度分析和层次聚类分析，以及传统的描述性和解释性统计进行分析。对辅音之间相似性评分的分析表明，听力受损的听众将音位标签应用于刺激，并基于这些标签而非语音未标记的声学特征进行评分。对识别数据的分析表明，那些最容易混淆的辅音对听众来说不一定在概念上最相似。
