目的：本研究的目的是检验（a）邻区密度（与目标词在语音上相似的词的数量）和频率变量对学龄前口吃儿童口吃样不流利的作用，以及（6）这些变量是否对口吃样不流利产生的类型有影响。方法：从每个参与者（N = 15）中获得500+词的语音样本。每个口吃的单词都随机与第一个在语法类别、熟悉程度和音节/音素数量上与之紧密匹配的单词配对。从网上数据库中获得口吃和流利词的频率、邻域密度和邻域频率值。结果：口吃词的频率和邻域频率低于流利词。包含部分词重复和声音重复的词在频率和/或邻域频率上也低于流利词，但这些频率变量对单音节词重复没有影响。邻里密度未能影响口吃的易感性的话，以及类型的口吃般的不流利produced.Conclusions：在一般情况下，研究结果表明，邻里和频率变量不仅影响的流畅性与言语中产生的话，但也有影响类型的口吃般的不流利产生。
Purpose: The purpose of this study was-to examine (a) the role of neighborhooddensity (number of words that are phonologically similar to a target word) and frequency variables on the stuttering-like disfluencies of preschool children who stutter, and (6) whether these variables have an effect on the type of stuttering-like disfluency produced.Method: A 500+ word speech sample was obtained from each participant (N = 15). Each stuttered word was randomly paired with the firstly produced word that closely matched it in grammatical class, familiarity, and number of syllables/phonemes. Frequency, neighborhood density, and neighborhood frequency values were obtained for the stuttered and fluent words from an online database.Results: Findings revealed that stuttered words were lower in frequency and neighborhood frequency than fluent words. Words containing part-word repetitions and sound prolongations were also lower in frequency and/or neighborhood frequency than fluent words, but these frequency variables did not have an effect on single-syllable word repetitions. Neighborhood density failed to influence the susceptibility of words to stuttering, as well as the type of stuttering-like disfluency produced.Conclusions: In general, findings suggest that neighborhood and frequency variables not only influence the fluency with which words are produced in speech, but also have an impact on the type of stuttering-like disfluency produced.
