The purpose of this project was to provide preliminary data on comparative judgments of tracheoesophageal (TE) speech intelligibility by two groups of listeners who varied in their listening sophistication. Four highly proficient TE talkers produced the stimuli for the study. Stimuli represented all consonant manner classes in both pre- and postvocalic contexts. The two listener groups were composed of 10 naive listeners and 10 experienced speech pathologists. Data from each listener group was analyzed for overall intelligibility and intelligibility by pre- and postvocalic phonetic position. Scores were also quantified by phonetic manner class. Statistically significant differences were identified between judgments of the two listener groups for prevocalic stops and fricatives. Experienced listeners did, however, generally judge talkers to exhibit higher intelligibility compared to naive listeners. The potential clinical implications of these data are discussed.
本项目的目的是提供初步数据，以了解两组听力水平不同的听众对食管气管（TE）语音清晰度的比较判断。四位高度熟练的TE说话者为该研究生成了刺激材料。刺激材料代表了元音前后语境中的所有辅音发音方式类别。两组听众分别由10名新手听众和10名经验丰富的言语病理学家组成。分析了每个听众组的数据，以了解总体清晰度以及元音前后语音位置的清晰度。分数也按语音发音方式类别进行了量化。在两组听众对元音前塞音和擦音的判断之间发现了统计学上的显著差异。然而，与新手听众相比，经验丰富的听众通常认为说话者的清晰度更高。讨论了这些数据潜在的临床意义。
