PURPOSE
To determine the influence of clear speech on auditory-perceptual judgments of speech acceptability and listener comfort for electrolaryngeal speech.
METHOD
Voice recordings were obtained from 10 electrolaryngeal speakers. Each speaker read the Rainbow Passage in two conditions: habitual speech and clear speech. Speakers were encouraged to speak as clearly as possible and over-articulate in the clear speech condition. Auditory-perceptual rating tasks were completed by 20 normal-hearing adults who evaluated 20 randomized voice recordings. Two counterbalanced listening sessions were used to gather ratings of speech acceptability and listener comfort.
RESULTS
A significant effect of speaking condition was found on listener judgments of speech acceptability, but not listener comfort. However, listener scores for speech acceptability and listener comfort were found to be significantly related. For all speakers, objective temporal measures indicated reduced speaking rates in the clear speech condition.
CONCLUSIONS
These findings suggest that volitional attempts to improve electrolaryngeal speech using clear speech might negatively impact listener judgments of speech acceptability, but not listener comfort. Further, the data suggest that speech acceptability and listener comfort might address unique perceptual entities. Overall, the strong relationship between these auditory-perceptual dimensions provide support for the use of scaled measurements to assess the impact of speech rehabilitation on individuals who use the electrolarynx.
目的
确定清晰言语对电子喉言语的言语可接受性听觉感知判断和听众舒适度的影响。
方法
从10名电子喉使用者处获取语音录音。每位使用者在两种情况下朗读《彩虹段落》：习惯性言语和清晰言语。在清晰言语条件下，鼓励使用者尽可能清晰地说话并过度发音。20名听力正常的成年人完成了听觉感知评分任务，他们对20个随机语音录音进行了评估。使用两个平衡的听力环节来收集言语可接受性和听众舒适度的评分。
结果
发现说话条件对听众的言语可接受性判断有显著影响，但对听众舒适度没有影响。然而，发现听众的言语可接受性得分和听众舒适度得分显著相关。对于所有使用者，客观的时间测量表明在清晰言语条件下说话速度降低。
结论
这些发现表明，使用清晰言语来改善电子喉言语的自主尝试可能会对听众的言语可接受性判断产生负面影响，但不会影响听众舒适度。此外，数据表明言语可接受性和听众舒适度可能涉及独特的感知实体。总体而言，这些听觉感知维度之间的强关系为使用量表测量来评估言语康复对使用电子喉的个体的影响提供了支持。
