The purpose of this study was to examine stuttering behavior in German-English bilingual people who stutter (PWS), with particular reference to the frequency of stuttering on content and function words. Fifteen bilingual PWS were sampled who spoke German as the first language (L1) and English as a second language (L2). Conversational speech was sampled in each language and analyzed for the percentage of overall stuttering-like disfluencies and distribution of stuttering on content and function words. Significantly more stuttering was found to occur in L2 compared to L1. Stuttering occurred significantly more often on content words compared to function words in L1. No significant difference between stuttering on function and content words was observed in L2. Examination across L1 and L2 found a significantly greater percentage of stuttering on function words in L2 compared to L1, and a significantly lower percentage of stuttering on content words in L2 compared to L1. The characteristics of stuttering in L2 could not be differentiated on the basis of an L2 proficiency measure. The differences observed in the amount of stuttering between L1 and L2 suggest that stuttering in bilingual speakers is closely related to language dominance, with features of stuttering in L2 indicative of a less developed language system.
本研究的目的是考察德英双语口吃者（PWS）的口吃行为，特别关注实词和虚词上的口吃频率。抽取了15名双语口吃者作为样本，他们的第一语言（L1）是德语，第二语言（L2）是英语。对每种语言的对话语音进行采样，并分析总体口吃样不流畅的百分比以及实词和虚词上的口吃分布情况。结果发现，与L1相比，L2中出现的口吃明显更多。在L1中，实词上的口吃比虚词更频繁。在L2中，未观察到虚词和实词上的口吃有显著差异。对L1和L2进行考察发现，与L1相比，L2中虚词上的口吃百分比显著更高，而与L1相比，L2中实词上的口吃百分比显著更低。无法根据L2熟练程度指标来区分L2中的口吃特征。在L1和L2之间观察到的口吃量差异表明，双语者的口吃与语言优势密切相关，L2中的口吃特征表明语言系统发育程度较低。
