在美式英语中,不发音的尾音/t/和/p/经常被声门化:它们有声门收缩,导致前面的元音发出嘎吱嘎吱的声音。先前的研究表明,这种全球化可以增强/t/,或者更普遍地说,增强结尾停顿的无声性。在这项研究中,我们考察了单词识别的时间进程,以测试全球化是否促进了以不发音的/t/和/p/结尾的单词的感知,如果全球化实际上是增强的,这是预期的。60名美国英语听众参加了一项眼球追踪研究,在这项研究中,他们听到了以/p、t、b、d/结尾的CVC英语单词的重新合成的声门音和非声门音版本,同时观看了一个显示两个单词的正字法。目标单词在发音位置(例如,cop-cot)或发音(例如,bat-bad, cap-cab)上有最小的差异。虽然很少有证据表明声门化有助于识别以/t/或/p/结尾的单词,但它有很强的抑制作用:当前一个元音被声门化时,以浊音顿音结尾的单词被识别得更慢、更差。这些发现并不能支持以听者为导向、以增强为基础的对美式英语尾语全球化现象的解释。另一方面,他们认为尾音/t/和/p/的声格化实例,而不是尾音/d/和/b/的声格化实例,被认为是这些声音的同样好的变体。
In American English, voiceless codas /t/ and /p/ are often glottalized: They have glottal constriction that results in creaky voice on the preceding vowel. Previous claims suggest that such glottalization can serve to enhance /t/ or, more generally, voicelessness of coda stops. In this study, we examine the timecourse of word recognition to test whether glottalization facilitates the perception of words ending in voiceless /t/ and /p/, which is expected if glottalization is in fact enhancing. Sixty American English listeners participated in an eye-tracking study, where they heard resynthesized glottalized and non-glottalized versions of CVC English words ending in /p, t, b, d/ while looking at a display with two words presented orthographically. Target words were presented with a minimal pair differing in place of articulation (e.g., cop-cot), or voicing, (e.g., bat-bad, cap-cab). Although there is little evidence that glottalization facilitates recognition of words ending in /t/ or /p/, there is a strong inhibitory effect: Words ending in voiced stops are recognized more slowly and poorly when the preceding vowel was glottalized. These findings lend little support to a listener-driven, enhancement-based explanation for the occurrence of coda glottalization in American English. On the other hand, they suggest that glottalized instances of coda /t/ and /p/, but not of coda /d/ and /b/, are perceived as equally good variants of these sounds.
