许多不同的研究者报告了美式英语/r/如何与邻近的片段共发音的相当大程度的变异性。声学和发音数据被用来调查这种变异的发言者的“rhotic”美国英语方言。解决的主要问题是在何种程度上节段上下文影响发音运动反映在F3轨迹。特别是，我们问的F3轨迹的持续时间是否受到冲突与非冲突的发音规范。通过自动程序测量F3共振峰轨迹持续时间，并比较形式为/'waCrav/和/waC'rav/的无意义单词，其中C表示唇音、齿龈音或软腭辅音，'标记音节重读。这些持续时间与/'warav/和/wa'rav/中的F3轨迹持续时间进行了比较。结果表明，F3轨迹持续时间是相似的辅音上下文中，这表明/r/的协同发音是通过重叠的一个稳定的/r/相关的发音手势与手势相邻的声音。这种解释，和一致性的F3时间过程与舌头运动/r/，支持舌头运动的直接措施，为一个主题。
A number of different researchers have reported a substantial degree of variability in how American English /r/ coarticulates with neighboring segments. Acoustic and articulatory data were used to investigate this variability for speakers of "rhotic" American English dialects. The major issue addressed is the degree to which segmental context affects articulatory movement as reflected in the F3 trajectory. In particular, we ask whether the duration of the F3 trajectory is affected by conflicting vs. nonconflicting articulatory specifications. The F3 formant trajectory durations were measured by an automatic procedure and compared for nonsense words of the form /'waCrav/ and /waC'rav/, where C indicates a labial, alveolar or velar consonant and ' marks the syllabic stress. These durations were compared to F3 trajectory durations in /'warav/ and /wa'rav/. Results indicated F3 trajectory durations were similar across consonant contexts, suggesting that coarticulation of /r/ is achieved by overlap of a stable /r/-related articulatory gesture with gestures for neighboring sounds. This interpretation, and the concordance of F3 time course with tongue movement for /r/, was supported by direct measures of tongue movement for one subject.
