The purpose of this study was to determine whether: (a) inexperienced listeners can reliably judge listener effort and (b) whether listener effort provides unique information beyond speech intelligibility or acceptability in tracheoesophageal speech. Twenty inexperienced listeners made judgments of speech acceptability and amount of effort required to listen to 14 male tracheoesophageal speakers using a paired comparison paradigm. Intelligibility was controlled to limit the analysis to the relationship between ratings of listener effort and speech acceptability. Results showed that as a group, inexperienced listeners reliably rated both speech acceptability and listener effort. In addition, ratings of speech acceptability and listener effort were strongly correlated (r>.99); however, there was evidence that some individual listeners assigned different ratings for each dimension for the same speech samples. Results have important implications for communication success for tracheoesophageal speakers.
Readers will be able to describe: (a) the measurement of listener burden in speech and (b) the differences and relationships among listener effort, speech acceptability and speech intelligibility.
本研究的目的是确定：（a）缺乏经验的听众能否可靠地判断听的努力程度；（b）在食管气管语音中，听的努力程度是否能提供超越言语可懂度或可接受性的独特信息。20名缺乏经验的听众采用配对比较范式，对14名男性食管气管发音者的言语可接受性和听的努力程度进行了判断。将可懂度控制在一定范围内，以便将分析限定在听的努力程度评分与言语可接受性之间的关系上。结果表明，作为一个群体，缺乏经验的听众能够可靠地对言语可接受性和听的努力程度进行评分。此外，言语可接受性评分和听的努力程度评分高度相关（r>.99）；然而，有证据表明，一些个体听众对相同言语样本的每个维度给出了不同的评分。这些结果对食管气管发音者的沟通成功具有重要意义。
读者将能够描述：（a）言语中听的负担的测量方法；（b）听的努力程度、言语可接受性和言语可懂度之间的差异及关系。
