This dissertation examines the associations between pragmatic meaning categories in English and specific realizations of prosodic prominence. It has been well-established that in Mainstream American English (MAE), prominence is often used to convey contrast. A more limited set of studies suggests that prosodic prominence may also be capable of…

This dissertation explores the relationship between quantitative phonetic measurements and listener identification of accents of English, focusing on phonetic distance and its perceptual correlates across various English accent varieties. The Levenshtein distance (LD) measure, which quantifies string similarity by calculating the minimum cost of…

Understanding speech in an accent or dialect different than one's own can be challenging. McLaughlin and Van Engen (2020) were the first to quantify this increase in listening effort using Task Evoked Pupillary Response (TEPR), a common measure of cognitive arousal. They found that monolingual, English speaking adults' pupils dilated more quickly…

Due in part to its complex nature, there is still much to uncover in the investigation of the neural processes that contribute to synchronization between speakers and listeners during communication in the context of social cognition, specifically between native and nonnative English speakers and listeners. This study used a novel method of…

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…

This dissertation examines whether and how psycholinguistic priming, and social knowledge are integrated in the identification of sociolinguistic variants. Using the English variable (ING), the alternation between -ing and -in' (e.g. thinking vs. thinkin') as a testing ground, this dissertation probes whether and how individuals utilize…

To become a native speaker, beyond obligatory rules, children need to learn systematic variation in the language, as it is present at all levels of language structure and is an integral part of linguistic knowledge. To give an example in English, speakers sometimes pronounce words ending in -ing with -in' (e.g., working vs. workin') depending on…

The perception and encoding of voice cues in consonants have been well studied, whereas there has been relatively little research on aspiration. The current study examined the encoding and perception of aspiration and voicing in Hindi, American English, and Tamil listeners when relevant cues were and were not degraded by noise. This study is novel…

Having historically received less attention than other linguistic structures (Derwing & Munro, 2005), second language (L2) pronunciation instruction represents an emergent area of research in the field (Thomson & Derwing, 2015). While several methods have been shown to be effective for improving L2 segmental production, including explicit…

Arabic emphasis refers to the production of consonants resulting from a primary constriction in the dental or alveolar region and a secondary constriction in the back of the vocal tract, recognized as 'Emphatic.' These have contrastive consonants produced in the dental or alveolar region, recognized as 'Plain.' The existing research on emphasis in…

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…

The question of whether second languages (L2s) are best learned implicitly or explicitly has been a topic of much empirical discourse, with the majority of studies pointing to the benefits of explicit instruction when learning L2 grammar rules. However, given the focus on grammar, it is unclear how generalizable these findings are to other…

This dissertation presents three studies that examined issues related to the production and the perception of pitch in a tone language. The first study examined linguistic contexts that may modulate consonant-induced pitch perturbations (CF0) in a tone language. Previous studies have produced mixed findings regarding the role of linguistic…

This dissertation research examines the acquisition of second language vowels. For second language learners, learning a new languages' sound inventory, particularly its vowels, presents a challenge perceptually and in terms of production. Incorrectly perceiving and producing sounds in a second language results in a foreign accent in many adult…

One hypothesis to explain perceptual narrowing in speech perception is the distributional learning account. This account claims that both infants and adults are able to infer the number of phonemic categories through observations of frequency distributions of individual phones in their speech input (Maye, Werker, & Gerken, 2002). Although the…
