摘要 先前的工作表明，一个单词的形态简单或复杂的状态可能反映在它的语音实现中。这些影响的一个可能来源是语音范式的一致性，其中预期单词的语音实现受到其形态相关的影响。例如，变形词 frees 的实现应该受到音系 for free 的影响，从而与形态简单的词 freeze 不谐音。我们通过分析四十个这样的屈折/简单单词对的产生来测试这一预测，这些单词对嵌入到伪会话语音中，其结构以避免元语言任务影响，并平衡频率、正字法以及片段和韵律上下文。我们发现，与简单的对应词（freeze、lapse）相比，词尾摩擦词（frees、laps）的词干和后缀持续时间显着长约 4-7%，而词尾停词的效果为零。结果表明词形影响其亲属的产生。
ABSTRACT Previous work demonstrates that a word's status as morphologically-simple or complex may be reflected in its phonetic realisation. One possible source for these effects is phonetic paradigm uniformity, in which an intended word's phonetic realisation is influenced by its morphological relatives. For example, the realisation of the inflected word frees should be influenced by the phonological plan for free, and thus be non-homophonous with the morphologically-simple word freeze. We test this prediction by analysing productions of forty such inflected/simple word pairs, embedded in pseudo-conversational speech structured to avoid metalinguistic task effects, and balanced for frequency, orthography, as well as segmental and prosodic context. We find that stem and suffix durations are significantly longer by about 4–7% in fricative-final inflected words (frees, laps) compared to their simple counterparts (freeze, lapse), while we find a null effect for stop-final words. The result suggests that wordforms influence production of their relatives.
