This paper investigates whether stuttering rates in English-speaking adults and children are influenced by phonological and morphological complexity at the ends of words. The phonology of English inflection is such that morphological and phonological complexity are confounded, and previous research has indicated that phonological complexity influences stuttering. Section 1 of this paper considers how to disentangle phonological and morphological complexity so that the impact of each on stuttering can be tested. Section 2 presents an analysis of some adult corpus data, and shows that phonological and morphological complexity at the word end do not influence stuttering rates for English-speaking adults, at least in spontaneous speech. Section 3 presents results from a non-word repetition task and a past tense elicitation task which reveal that while word-end phonological and morphological complexity do not affect stuttering rates in most of the adults and children tested, a small proportion of adults and children do stutter over morphologically complex words in an elicitation task. Taken as a whole, these results suggest that morphology has an impact on stuttering for some individuals in certain circumstances.
本文研究了说英语的成年人和儿童的口吃发生率是否受单词词尾的音系和形态复杂性影响。英语屈折变化的音系使得形态复杂性和音系复杂性相互混淆，而先前的研究表明音系复杂性会影响口吃。本文第1节探讨了如何区分音系复杂性和形态复杂性，以便能够测试二者对口吃的影响。第2节对一些成人语料库数据进行了分析，结果表明，至少在自然言语中，词尾的音系和形态复杂性不会影响说英语成年人的口吃发生率。第3节展示了一项非词重复任务和一项过去式引出任务的结果，这些结果表明，虽然在大多数接受测试的成年人和儿童中，词尾的音系和形态复杂性不会影响口吃发生率，但在引出任务中，一小部分成年人和儿童在形态复杂的单词上确实会口吃。总体而言，这些结果表明，在某些情况下，形态对一些个体的口吃有影响。
