Abstract

The purpose of this study is to investigate the gradient tendencies of dissimilatory /r/-dropping in American English, with a focus on determining which of the two /r/s in a word is more likely to be deleted depending on different phonological environments. Utilizing both audio and text data from the Buckeye Corpus, we conducted a comprehensive quantitative analysis with Random Forest, considering three phonological factors: stress, syllable position, and word-edge. Our findings, aligned with previous research, confirm that the likelihood of /r/-dropping is significantly influenced by these factors. We also found that the probability of /r/-deletion is not solely governed by the individual position of an /r/, but by its relative position with another /r/. For instance, the first /r/ is predominantly dropped in unstressed coda positions when the succeeding /r/ is in a stressed onset, but the second /r/ is more prone to deletion where it is in an unstressed coda. Finally, key structures exhibiting high deletion probabilities of the first /r/ were identified, with certain patterns showing a notable tendency for the second /t/ to drop.

基于七叶语料库的美式英语中异化/r/降音的定量分析

本研究的目的是研究美式英语中异化的/r/下降的梯度趋势，重点是根据不同的语音环境确定一个单词中的两个/r/中哪一个更容易被删除。利用来自七叶树语料库的音频和文本数据，我们使用Random Forest进行了全面的定量分析，考虑了三个音系因素:重音、音节位置和词边。我们的发现与之前的研究一致，证实了/r/-下降的可能性受到这些因素的显著影响。我们还发现，/r/-缺失的概率不仅取决于一个/r/的个体位置，还取决于它与另一个/r/的相对位置。例如，当后面的/r/处于重音开头时，第一个/r/在非重读结尾时主要被省略，但第二个/r/在非重读结尾时更容易被省略。最后，发现了第一个/r/缺失概率高的关键结构，其中某些模式显示第二个/t/缺失的显著趋势。

期刊介绍： Concentric: Studies in Linguistics is a refereed, biannual journal, publishing research articles on all aspects of linguistic studies on the languages in the Asia-Pacific region. Review articles and book reviews with solid argumentation are also considered. The journal is indexed in Scopus, Emerging Sources Citation Index (ESCI), Modern Language Association (MLA) Directory of Periodicals, MLA International Bibliography, Linguistics & Language Behavior Abstracts (LLBA), EBSCOhost, Communication & Mass Media Complete (CMMC), Airiti Library (AL), Taiwan Citation Index-Humanities and Social Sciences, and Taiwan Humanities Citation Index(THCI)-Level 1. First published in 1964 under the title,The Concentric, the journal aimed to promote academic research in the fields of linguistics and English literature, and to provide an avenue for researchers to share results of their investigations with other researchers and practitioners. Later in 1976, the journal was renamed as Studies in English Literature and Linguistics, and in 2001 was further renamed as Concentric: Studies in English Literature and Linguistics. As the quantity of research in the fields of theoretical linguistics, applied linguistics, and English literature has increased greatly in recent years, the journal has evolved into two publications. Beginning in 2004, these two journals have been published under the titles Concentric: Studies in Linguistics and Concentric: Literary and Cultural Studies respectively.
