这项研究调查了在清晰的说话风格下进行的适应是否比在随意风格下的适应产生了更容易辨别的语音类别。对40名成年人进行多次重复关键词--首字母/S/-/ʃ/，通过图片描述进行随意清晰的语音描述。对于质心，清晰语音的跨类别距离增加，但类别内的离散度没有变化，对区分度也没有影响。然而，说话者产生的/S/-/ʃ/区分的质心在模糊区域的记号较少。这些结果表明，尽管交际者对交际成功的反馈可能会促进更大的分段适应，但某些适应并不是必须发生的。
This study investigated whether adaptations made in clear speaking styles result in more discriminable phonetic categories than in a casual style. Multiple iterations of keywords with word-initial /s/-/ʃ/ were obtained from 40 adults in casual and clear speech via picture description. For centroids, cross-category distance increased in clear speech but with no change in within-category dispersion and no effect on discriminability. However, talkers produced fewer tokens with centroids in the ambiguous region for the /s/-/ʃ/ distinction. These results suggest that, whereas interlocutor feedback regarding communicative success may promote greater segmental adaptations, it is not necessary for some adaptation to occur.
