外国人引语是一种经常被引用的言语风格，但它的声学特性却出人意料地缺乏研究，许多现有的研究唤起了想象中的对话者来引出外国人引语。本研究从声学角度对外国人言语和母语言语在真实和想象条件下的差异进行了比较。十名以英语为母语的人在地图上向两名南部邦联听众(一名以英语为母语的人和一名以普通话为母语的人)和两名想象中的听众(一名被描述为英语母语者，另一名被描述为非母语者)描述了地标之间的路径。考察了22个目标词在母语为外国人和真实想象条件下的元音时长、发音率和元音中心度。外国人主导的重读元音比母语导向的元音更长，语速更慢。此外，在外国人引导的情况下，/ae/在元音空间中更偏向边缘。这些影响在现实和图像中都是一致的。
Foreigner‐directed speech is a much cited speech style, but its acoustic properties are surprisingly under‐studied, and many existing studies evoke imagined interlocutors to elicit foreigner‐directed speech. This study provides an acoustic comparison of foreigner‐directed and native‐directed speech in real and imaginary conditions. Ten native English speakers described the path between landmarks on a map to each of two confederate listeners (one native English speaker and one native Mandarin speaker) and to two imagined listeners (one described as a native English speaker and the other as a non‐native speaker). Vowel duration, rate of speech, and vowel centralization were examined across native‐foreigner and real‐imagined conditions in 22 target words. Stressed vowels were longer and rate of speech was slower in foreigner‐directed than in native‐directed speech. Additionally, /ae/ was more peripheral in the vowel space in the foreigner‐directed condition. These effects were consistent across real and imag...
