Two acoustic studies of voice onset time (VOT) in sibilant-stop (ST) consonant clusters, produced by first language (L1) speakers of Polish, are presented. In the first, a baseline study of L1 Polish comparing ST clusters with initial singleton stops, a small degree of VOT shortening after /s/ was found for /p/, but not /t/. The second study…

This study aimed to investigate the production of stress in English compound nouns and phrasal verbs by L1 Thai learners. Based on the Interlanguage Hypothesis (Corder, 1982; Selinker, 1972), it was hypothesized that (1) there is a positive relationship between English proficiency levels and accuracy in stress assignment in compound nouns and…

Given the controversies surrounding the critical period hypothesis on second-language (L2) learning outcomes, this study focuses on the phonological aspect of language acquisition--the strength of the foreign accent in L2. Drawing on data from a large-scale representative data set on immigrant adolescents in Germany--CILS4EU-DE--we first…

This study investigated the role of cross-linguistic similarity in the acquisition of Russian initial stop contrasts by Chinese learners, addressing two specific research questions: (1) How similar are Russian voiced stops to Mandarin stops for Chinese learners?; and (2) How can the speech learning model (SLM) be applied to account for the…

This dissertation investigates language-specific acoustic and aerodynamic phenomena in language contact situations. Whereas most work on second language and bilingual phonology has focused on individual consonants and vowels, this project examines patterns of coarticulation in the two languages of Spanish-English and French-English bilingual…

Research suggests that second language words are learned faster when they are similar in phonological structure or accent to the words of an individual's first language. Many major theories suggest this happens because of differences in frequency of exposure and context between first and second language words. Here, we examine the independent…

This study tests the hypothesis that late first-language English / second-language Spanish learners (L1 English / L2 Spanish learners) acquire spirantization in stages according to the prosodic hierarchy (Zampini, 1997, 1998). In Spanish, voiced stops [b d g] surface after a pause or nasal stop, and continuants [ß? ð? ??] surface postvocalically,…

This study investigates the degree to which native-English-speaking learners of Spanish can generate expectations for information likely to occur in upcoming portions of an unfolding linguistic signal. We examine Spanish clitic left dislocation, a long-distance dependency between a topicalized object and an agreeing clitic, whose felicity depends…

Variability in the form of article (i.e., a and the) omissions and stressing has been attributed to a mismatch between first (L1) and second language (L2) prosodic and syntactic structures. An overlap between the L1 and L2 systems, on the other hand, is expected to contribute to native-like article productions. This case study aims to explore the…

This study examined Spanish-Welsh (in Patagonia) and Welsh-English (in North Wales) bilingual children's and adults' processing of sentences in which two noun phrases acted as arguments of a verb. The goal was to determine the relative importance of distinct cues to the identification of the subject in the bilinguals' processing of their two…

Over the past decades, various teaching methods adopted from time to time have placed pronunciation teaching in the forefront or in the backend. This has resulted in second language facilitators to completely disregard or relentlessly correct pronunciation depending on their intuition due to the lack of research on pronunciation teaching or proper…

This study investigates whether a natural order exists for non-native acquisition in the production of English syllable coda obstruents by Korean and Chinese adult native speakers. We recorded L2 English monosyllabic words produced by 66 Chinese and 51 Korean native speakers. The recorded speech was then evaluated by 11 native-speaker listeners of…

Late second language (L2) learners often struggle with L2 prosody, both in perception and production. This may result from first language (L1) interference or some property of how a second language functions in a late learner independent of what their L1 might be. Here we investigate prosody's role in determining information structure through…

The current study unites multiple theories (i.e., the orthographic depth hypothesis and linguistic grain size theory, the simple view of reading, and the common underlying proficiency model) to explore differences in how 113 fourth-grade Spanish-speaking English learners (ELs) approached reading in their native language of Spanish, which is…

Learning new vocabulary words in a second language is a challenge for the adult learner, especially when the second language writing system differs from the first language writing system. According to the lexical quality hypothesis (Perfetti & Hart, 2001), there are three constituents to word-level knowledge: orthographic, phonological, and…
