This dissertation investigates intuitions about Spanish syllable structure and whether or not word segmentation strategies are affected by these syllabic intuitions. The study utilizes monolingual Spanish speakers, L1 Spanish speakers who are L2 learners of English and L1 English speakers who are L2 learners of Spanish. For Spanish syllabic…

With the increasing prevalence of autism diagnoses globally, the overall aim of this dissertation is to improve our understanding of the linguistic aptitude of autistic individuals. Given that the autism diagnosis is a spectrum, we rely on the Autism Quotient (AQ) test, which measures the quantity of autistic-like traits an individual possesses,…

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…

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 investigated how a bilingual's experiences can affect how their first language pronunciation can differ from monolingual speakers of their two languages. We used a methodology incorporating quantitative phonetic measurements of voice onset time and vowel formants, grammar and vocabulary tests, and qualitative measures of language…

Although Spanish and Italian voiced stops are similar in articulatory (place of articulation) and acoustic (prevoicing) terms, there are important contrasts associated with these sounds in each language that may affect second language (L2) learners' acquisition. Spanish maintains an allophonic alternation between word-initial voiced stops and…

The rapid growth of Mandarin Chinese and English dual-language (DL) programs and the differences between these two languages have fostered the need to investigate the early literacy performance of young students in a Mandarin/English DL program. This study used the interactive transfer framework (Chung et al., 2019) to understand the Mandarin and…

This study aimed to investigate the effect of written cues on the second- language (L2) language perception, processing, and word learning, especially when the person's first language (L1) belongs to a different rhythmic type of language than L2. The first objective was to examine whether late bilinguals as L2 learners can benefit more from…

In Spanish, the phoneme /s/ has two variants: [z] occurs in the coda when preceding a voiced consonant, and [s] occurs elsewhere. However, recent research has revealed irregular voicing patterns with regards to this phone. This dissertation examines two of these allophonic variations. It first investigates how speech rate and speech formality…

This dissertation investigated the speech productions of the implosive -r consonant by U.S.-born Puerto Rican and Dominican Heritage Language Spanish speakers in New York. The following main research questions were addressed: 1) Do heritage language Caribbean Spanish speakers evidence the same variation with the /?/ consonant in the implosive…

Because language, as a method of communication, is a two-way channel involving both speakers and listeners, a methodical study of linguistic variation should involve an analysis of both, how it is expressed and how it is interpreted. Furthermore, because language is known to vary between individuals (inter-speaker variation) as well as at the…
