The purpose of this study was to examine the effects of contrastive stress and phonetic context on misarticulations of consonantal /r/. Subjects were 9 children between the ages of 4:5 (years:months) and 5:7 who exhibited normal articulation development but inconsistently misarticulated /r/. The experimental task was designed to elicit consonantal /r/ in two phonetic contexts ([rV] & [CrV]) and two stress conditions (primary & nonprimary stress). Three listeners who were naive to the experimental hypotheses judged the children's productions for accuracy of /r/ production and for stress. Significant main effects were obtained for context and stress: /r/ productions were more often judged as correct in clusters than in singletons and in words not receiving primary stress than in words receiving primary stress. Results are discussed in terms of the possible effects of production and perceptual variables on listener judgments. Inferences are drawn concerning future research on speaker and listener effects in the study of articulation.
本研究的目的是考察对比重音和语音语境对辅音/r/发音错误的影响。研究对象是9名年龄在4岁5个月至5岁7个月之间的儿童，他们的发音发展正常，但/r/的发音不一致。实验任务旨在在两种语音语境（[rV]和[CrV]）和两种重音条件（主重音和非主重音）下引出辅音/r/。三名对实验假设不知情的听众判断儿童发音中/r/的发音准确性和重音情况。在语境和重音方面获得了显著的主效应：/r/在音节中比在单音中、在非主重音的单词中比在主重音的单词中更常被判断为正确。根据发音和感知变量对听众判断可能产生的影响对结果进行了讨论。得出了关于未来在发音研究中对说话者和听众影响的研究推论。
