Purpose

We explore the validity and reliability of an Audience Response Systems (ARS)-based measure of acceptability, applied to speech produced by children with speech sound disorder (SSD). We further explore how the suggested measure relates to an ARS-based measure of intelligibility. Finally, we explore potential differences between speech-language pathologists (SLPs), untrained adults, and children in their assessments.

Method

Fifty-three listeners participated in ARS-based assessments of acceptability and intelligibility: 19 SLPs, 18 untrained adults, and 16 children (aged 6-10 years). The listeners assessed speech samples collected from 14 children with SSD and 2 children with typical speech. The validity of the ARS-based acceptability measure was investigated through correlation analyses with reference to rating-based acceptability, as well as to measures of intelligibility and speech proficiency.

Results

The ARS-based acceptability measure correlated strongly with all assumed related measures. Listeners reacted more often to affected acceptability than to unintelligibility. Child listeners reacted less frequently to acceptability disruption than the SLPs and untrained adults.

Conclusions

ARS-based assessment of acceptability provides a valid and reliable measure of acceptability. The ARS-based methodology captures an anticipated pattern where listeners react more often to disruptions of acceptability than to unintelligibility. Children appear less sensitive to traits signaling SSD than SLPs and other adults are; however, replication is required to establish this for sure.

通过基于听众响应系统的评估来了解语音混乱的可接受性

目的

我们探索了基于听众反应系统（ARS）的可接受性度量的有效性和可靠性，该度量适用于患有语音障碍（SSD）的儿童所产生的语音。我们将进一步探讨建议的度量与基于ARS的清晰度度量之间的关系。最后，我们探讨了言语病理学家（SLP），未经训练的成年人和儿童在评估中的潜在差异。

方法

53名听众参加了基于ARS的可接受性和清晰度的评估：19位SLP，18位未经培训的成年人和16位儿童（6至10岁）。听众评估了从14名有SSD的儿童和2名有典型语音的儿童收集的语音样本。通过参考基于等级的可接受性以及清晰度和言语熟练程度的相关性分析，对基于ARS的可接受性度量的有效性进行了调查。

结果

基于ARS的可接受性度量与所有假定的相关度量高度相关。听众对受影响的可接受性的反应比对难以理解的反应更频繁。与SLP和未经训练的成年人相比，儿童听者对可接受性破坏的反应较不频繁。

结论

基于ARS的可接受性评估提供了有效和可靠的可接受性度量。基于ARS的方法捕获了一种预期的模式，在这种模式中，听众对可接受性中断的反应要多于对不可理解性的反应。与SLP和其他成年人相比，儿童对发信号表明SSD的性状不那么敏感。但是，必须进行复制才能确定这一点。
