This study is part of a larger investigation designed to assess the ability of esophageal speakers to effect systematic changes in listener perceptions of syllable stress. Ten male functional esophageal speakers and ten normal speakers were instructed to produce 25 repetitions of the disyllable/mama/ using five different conditions of syllable stress, ranging from strong first syllable stress through strong second syllable stress. Nine normal listeners judged both relative and absolute syllable stress of the disyllables, using a nine-point scale for each syllable. The results indicated that highly reliable judgments can be made when judging relative and absolute syllable stress in disyllables produced by both normal and esophageal speakers. In response to experimenter direction, both normal and esophageal speakers are able to effect systematic changes of direction and degree in listener perceptions of relative stress.
本研究是一项更大规模调查的一部分，该调查旨在评估食管发声者改变听众对音节重音感知的系统变化的能力。十名男性功能性食管发声者和十名正常发声者被要求在五种不同的音节重音条件下，从第一个音节重音强到第二个音节重音强，重复发出双音节/mama/ 25次。九名正常听众使用九点量表对双音节的相对和绝对音节重音进行判断。结果表明，在判断正常发声者和食管发声者发出的双音节的相对和绝对音节重音时，可以做出高度可靠的判断。根据实验者的指示，正常发声者和食管发声者都能够在听众对相对重音的感知上实现方向和程度的系统变化。
