我们目前的舌腭接触（EPG）和声学数据英语的咝咝声同化，特别关注的不对称性所产生的咝咝声的顺序。众所周知，/s#/序列在流利的语音中可能会表现出不同程度的回归同化，然而对于/s #/序列，人们普遍认为没有同化发生，尽管这一假设的经验内容很少被调查，也没有提出明确的理论解释。 本文系统地比较了两种擦音语序在词界语簇中的异同。我们的数据表明，/s#/序列同化频繁，这种同化是严格的回归。 通过我们的测量，同化序列可能无法与同源对照序列区分开，或者其特征在于测量值介于/s/或/s/的典型值之间。 /n #s/序列也可能表现出退化同化，尽管频率较低，程度较低。 同化的/s #s/序列总是可以与/s#s/序列区分开来。 在少数情况下，我们识别出/#s/的渐进同化。 我们讨论了如何解释同化程度的差异，我们提出，顺序不对称可能会产生从不同的发音控制结构，结合phonotactic概率效应的两个咝音。
We present tongue-palate contact (EPG) and acoustic data on English sibilant assimilation, with a particular focus on the asymmetry arising from the order of the sibilants. It is generally known that /s#ʃ / sequences may display varying degrees of regressive assimilation in fluent speech, yet for / ʃ #s/ it is widely assumed that no assimilation takes place, although the empirical content of this assumption has rarely been investigated nor a clear theoretical explanation proposed. We systemat ically compare the two sibilant orders in word-boundary clusters. Our data show that /s#ʃ / sequences assimilate frequently and this assimilation is strictly regressive. The assimilated sequence may be indistinguishable from a homorganic control sequence by our measures, or it can be characterized by measurement values intermediate to those typical for / ʃ / or /s/. / ʃ #s/ sequences may also show regressive assimilation, albeit less frequently and to a lesser degree. Assimilated / ʃ #s/ sequences are always distinguishable from /s#s/ sequences. In a few cases, we identify progressive assimilation for / ʃ #s/. We discuss how to account for the differences in degree of assimilation, and we propose that the order asymmetry may arise from the different articulatory control structures employed for the two sibilants in conjunction with phonotactic probability effects.
