ABSTRACT

Speakers learning a second language show systematic differences from native speakers in the retrieval, planning, and articulation of speech. A key challenge in examining the interrelationship between these differences at various stages of production is the need for manual annotation of fine-grained properties of speech. We introduce a new method for automatically analysing voice onset time (VOT), a key phonetic feature indexing differences in sound systems cross-linguistically. In contrast to previous approaches, our method allows reliable measurement of prevoicing, a dimension of VOT variation used by many languages. Analysis of VOTs, word durations, and reaction times from German-speaking learners of Spanish (Baus et al., 2013 Baus, C., Costa, A., & Carreiras, M. (2013). On the effects of second language immersion on first language production. Acta Psychologica, 142(3), 402–409. https://doi.org/10.1016/j.actpsy.2013.01.010[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) suggest that while there are links between the factors impacting planning and articulation, these two processes also exhibit some degree of independence. We discuss the implications of these findings for theories of speech production and future research in bilingual language processing.

摘要

学习第二语言的说话者在语音的检索、规划和表达方面与母语者表现出系统性差异。在不同生产阶段检查这些差异之间的相互关系的一个关键挑战是需要对语音的细粒度属性进行手动注释。我们介绍了一种自动分析语音起始时间 (VOT) 的新方法，这是一种跨语言索引声音系统中的关键语音特征。与以前的方法相比，我们的方法允许可靠地测量预发音，这是许多语言使用的 VOT 变化的维度。西班牙语德语学习者的 VOT、单词持续时间和反应时间分析（Baus 等人，2013 年） Baus, C.、Costa, A.和Carreiras, M.（2013 年）。第二语言沉浸对第一语言产生的影响。心理学学报，142（3），402 – 409。https://doi.org/10.1016/j.actpsy.2013.01.010 [Crossref]、[PubMed]、[Web of Science®]、[  Google Scholar]）表明，虽然影响规划和表达的因素之间存在联系，这两个过程也表现出一定程度的独立性。我们讨论了这些发现对双语语言处理的语音产生理论和未来研究的影响。
