Eight native speakers of American English each produced ten tokens of all possible CV, FCV, and VFCV utterances with V = [a] or [u], F = [s] or [integral of], and C = [t] or [k]. Acoustic analysis showed that the formant transition onsets following the stop consonant release were systematically influenced by the preceding fricative, although there were large individual differences. In particular, F3 and F4 tended to be higher following [s] than following [integral of]. The coarticulatory effects were equally large in FCV (e.g.,/sta/) and VFCV (e.g.,/asda/) utterances; that is, they were not reduced when a syllable boundary intervened between fricative and stop. In a parallel perceptual study, the CV portions of these utterances (with release bursts removed to provoke errors) were presented to listeners for identification of the stop consonant. The pattern of place-of-articulation confusions, too, revealed coarticulatory effects due to the excised fricative context.
八位以美式英语为母语的人分别产出了所有可能的CV、FCV和VFCV发音的十个样本，其中V为[a]或[u]，F为[s]或[ʃ]，C为[t]或[k]。声学分析表明，尽管个体差异较大，但塞音除阻后的共振峰过渡起始受到前一个擦音的系统性影响。具体而言，F3和F4在[s]之后往往比在[ʃ]之后更高。协同发音效应在FCV（如/sta/）和VFCV（如/asda/）发音中同样显著；也就是说，当擦音和塞音之间有音节边界介入时，协同发音效应并未减弱。在一项平行的感知研究中，这些发音的CV部分（去除释放音爆以引发错误）被呈现给听众，以识别塞音。发音部位混淆的模式也揭示了由于去除的擦音语境而产生的协同发音效应。
