本研究的目的是评估是否隐性修复假说（CRH; Postma & Kolk，1993），一个理论，旨在解释发生言语不流利的成年人口吃，也可以解释选定的言语特征的儿童口吃和表现出紊乱的语音。受试者为9名口吃并表现出正常语音的男孩（S + NP;平均年龄= 61.33个月;SD= 10.16个月）和9名口吃并表现出语音紊乱的男孩（S + DP;平均年龄= 59.11个月;SD= 9.37个月）。每个孩子的语音流畅性和语音的选择方面进行了分析的基础上的音频/录像图片命名任务和30分钟的对话与他的母亲的互动。结果表明，S + NP和S + DP儿童的基本言语不流利，非系统性言语错误，自我修复行为方面是大致相当的。CRH的预测，即发音速度快或反应时间短的话语更可能包含言语错误或言语不流畅，这一预测不被支持。CRH的预测关于言语不流利和言语错误的共同发生支持非系统性（“口误”），但不支持系统性（语音过程/基于规则），言语错误。此外，无论是S + NP还是S + DP主题修复他们的系统性语音错误在会话讲话，这表明系统偏离成人形式可能不代表真正的“错误”，至少对于一些儿童表现出语音过程。研究结果表明，言语不流利可能不代表对话过程中产生的系统性言语错误的自我修复的副产品，但非系统性言语错误的自我修复可能与儿童的言语不流利的生产。
The purpose of this study was to evaluate whether the Covert Repair Hypothesis (CRH; Postma & Kolk, 1993), a theory designed to account for the occurrence of speech disfluencies in adults who stutter, can also account for selected speech characteristics of children who stutter and demonstrate disordered phonology. Subjects were 9 boys who stutter and exhibit normal phonology (S + NP; mean age = 61.33 months;SD= 10.16 months) and 9 boys who stutter and exhibit disordered phonology (S + DP; mean age = 59.11 months;SD= 9.37 months). Selected aspects of each child’s speech fluency and phonology were analyzed on the basis of an audio/videotaped picture-naming task and a 30-min conversational interaction with his mother. Results indicated that S + NP and S + DP children are generally comparable in terms of their basic speech disfluency, nonsystematic speech error, and self-repair behaviors. CRH predictions that utterances produced with faster articulatory speaking rates or shorter response time latencies are more likely to contain speech errors or speech disfluencieswere notsupported. CRH predictions regarding the co-occurrence of speech disfluencies and speech errorsweresupported for nonsystematic (“slip-of-the-tongue”), but not for systematic (phonological process/rule-based), speech errors. Furthermore, neither S + NP nor S + DP subjects repaired their systematic speech errors during conversational speech, suggesting that systematic deviations from adult forms may not represent true “errors,” at least for some children exhibiting phonological processes. Findings suggest that speech disfluencies may not represent by-products of self-repairs of systematic speech errors produced during conversational speech, but that self-repairs of nonsystematic speech errors may be related to children’s production of speech disfluencies.
