本研究关注的是标准英式英语中的lax /u/-fron，特别是这种声音的变化是否可以归因于上下文的协同发音效应的感知补偿的减弱。年轻和年长的发言者产生了各种单音节，其中/u/出现在不同的对称辅音背景。同样的说话者参加了一个被迫选择知觉实验，在这个实验中，他们对嵌入在前置/s_t/和非前置/w_I/语境中的合成/I-u/连续体进行了分类。/u/被证明在生产和感知方面都领先于年轻年龄组。虽然没有确凿的证据表明，年轻的听众补偿coarticulation比年长的听众，coarticulatory的辅音上下文的影响/u/在知觉的大小被认为是小于生产的年轻人比老年组。研究结果是一致的声音变化的模型，其中感知补偿coarticulation减弱之前发生的变化，coarticulation的关系，在语音生产。因此，对于参与声音变化的一些说话者-听者来说，协同发音的感知和产生可能相对于彼此不寻常地不对准。
The present study is concerned with lax /u/-fron in Standard British English and in particular with whether this sound change in progress can be attributed to a waning of the perceptual compensation for the coarticulatory effects of context. Younger and older speakers produced various monosyllables in which /u/occurred in different symmetrical consonantal contexts. The same speakers participated in a forced-choice perception experiment in which they categorized a synthetic /I-u/continuum embedded in fronting /s_t/ and non-fronting /w_I/ contexts. /u/ was shown to be fronted for the younger age group in both production and perception. Although there was no conclusive evidence that younger listeners compensated less for coarticulation than did older listeners, the size of the coarticulatory influence of consonantal context on /u/ in perception was found to be smaller than in production for the younger than for the older group. The findings are consistent with a model of sound change in which the perceptual compensation for coarticulation wanes ahead of changes that take place to coarticulatory relationships in speech production. As a result, the perception and production of coarticulation may be unusually misaligned with respect to each other for some speaker-listeners participating in a sound change in progress.
