This study investigates the effects of native language experience and phonetic properties on the discrimination of labial-velar versus labial and velar contrasts, as well as voicing contrasts in labials, velars, and labial-velars. Research indicates that phonological perceptions are influenced by native language experience and the specific…

Listeners selectively tune in to the most relevant cues for contrasting sounds, and this process impacts their perceptual sensitivity to these cues (Nosofsky, 1986; Pisoni, 1991). For bilingual listeners, recent work suggests a shared L1/L2 phonology system with the phonetic properties of each sound established in a language-specific way…

Background: Bilingual speech production studies have highlighted that level of proficiency influences the acoustic-phonetic representation of phonemes in both languages (MacKay, Flege, Piske, & Schirru 2001; Zarate-Sandez, 2015). The results for bilingual speech production reveals that proficient/early bilinguals produce distinct acoustic…

The problem addressed in this study was that second language learners have difficulties pronouncing some English consonants that are not part of their language. Such errors occur because of first-language interference. The purpose of this qualitative case study was to explore the perceived effectiveness of using minimal pair training to…

This study investigated English phonological awareness in adult native speakers of English (L1) and in relation to their phonological awareness skills and proficiency in their German (L2). Most research in L1 phonological awareness focuses on younger children, their phonological awareness development, the relationship between reading and…

In the "Sound Pattern of English," Chomsky and Halle (1968) posited that English orthography, despite the complexity in how it relates to phonology, is in fact more "optimal" in at least one aspect: how it relates to morphology. A root or stem tends to maintain a constant visual form across words built upon it even as its…

Phonotactic patterns are generalizations that govern the order of consonants and vowels, within words and syllables. Certain second-order phonotactic patterns--those that relate multiple sounds within a syllable, such as "if the vowel is [near-close near-front unrounded vowel], then [s] can only appear at the end of the…

This dissertation examines the development of the internal structure of the Korean syllable by adult Korean learners whose native language is English. Prior research has identified the prominence of the body constituent in Korean and the rime constituent in English. The current study focuses on the acquisition of the body unit by English speakers…

Many studies evidence the flexibility of speech perception in the first language (L1), which allows rapid adaptation to unfamiliar foreign accents. Two influential studies by Bradlow and Bent (2008) and a follow-up study by Baese-Berk et al. (2013) found that increased variability as a function of the number of talkers and accents facilitated the…

Within the field of linguistics, whether considering language contact situations (Weinreich, 1979) or foreign language education (Lado, 1957), the topic of language transfer, especially as it relates to pronunciation, has always been an item of particular interest. While research on such transfer has mostly focused on various phenomena of the L1…

Nawat, the highly endangered indigenous language of El Salvador, is undergoing a revitalization process. This dissertation, conceived within this context, focuses on the second-language (L2) acquisition of features of Nawat pronunciation by learners who have Salvadoran Spanish as their first language (L1). Specifically, I assess the acquisition of…

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…

Individuals with lower proficiency in a second language tend to produce more disfluent speech patterns in the second language. Speech disfluencies refer to interruptions in the forward flow of speech and are distinct from the colloquial use of "fluency," to characterize knowledge of a language. Prior research indicates that some speech…

Millions engage in learning a Second Language (L2) using their mobile devices with a wide range of success. Concomitantly, there exists a growing interest in research on the effects of mobile-assisted language learning and predictors of learner outcomes (e.g., Loewen et al., 2020; Sudina & Plonsky, 2023). However, few of these apps and studies…

This dissertation investigates a typologically rare linguistic phenomenon found in Irish from three different perspectives: how it challenges phonological theory, how it is used by contemporary speakers, and how its written representation affects its acquisition. Initial consonant mutation (ICM), as it appears in the Celtic languages, is known to…
