The revised Speech Learning Model (SLM-r) postulates that learners with more precisely defined categories in their native language (L1) exhibit greater proficiency in acquiring sounds in a second language (L2). Despite its recent emergence, empirical studies validating this hypothesis remain scarce. This study aims to investigate the predictive…

Although second language (L2) learners often have difficulty with learning the L2 pronunciation, the literature has reported a mix of more successful and less successful learners. Many factors could contribute to individual variation in L2 speech sound learning. This dissertation examines a few factors that are hypothesized to influence L2…

This study examines the effectiveness of study abroad and pragmatic instruction on L2 learners' acquisition of the speech acts of requesting, thanking, and refusing. In the study, speech acts produced by L2 learners of Spanish who studied abroad for six weeks in Buenos Aires, Argentina and L2 learners who received eight weeks of pragmatic…

The goal of this dissertation is to better understand the targets of vowels in speech production. Three experiments investigate vowel production in non-native speech, probing how new vowel categories, and thus targets, are formed. Three research questions are addressed: (1) Do vowels have articulatory targets (as predicted by Browman &…

The purpose of this paper was to study the effectiveness of language acquisition using speaker instruction and listener instruction and examining the emergence of bidirectional intraverbals using a non-sense language. Current research suggests that speaker type instruction is more effective in aiding untrained relations (Contreras et al., 2020;…

The recent world pandemic has highlighted the need for effective procedures to teach language in Computer Assisted Language Learning (CALL) environments. Fully online and asynchronous classrooms are especially challenged when addressing learning to speak a foreign language toward greater communicative competence. Current CALL research is…

The field of study abroad for language learning has drawn extensively on related fields such as applied linguistics and psychology to conceptualize learners' experiences, which then informs how practitioners go about designing programs for those learners. Research has encouraged practitioners to increase learners' access to the target language…

This study investigates acoustically one of long-term debated phonetic characteristics, the so-called Arabic voiced pharyngeal fricative /[voiced pharyngeal fricative]/. Most recent studies have found the Arabic pharyngeal to be approximant, while others have categorized it as a stop in careful speech, and still others have suggested it is a…

"How can teachers help students improve their second language (L2) speaking accuracy?" This is a question that most L2 educators ask themselves every day. Although L2 writing is a popular topic among Second Language Acquisition (SLA) researchers, the consideration that L2 writing has the potential to act as a scaffold for L2 speaking…

The study explores the attitudes of undergraduate Flagship students in the United States towards Arabic-accented speech in English. It examines the Familiarity Principle among these students and analyzes their attitudes based on socio-intellectual status, aesthetic quality, and dynamism of Arabic-accented speech. The study also discusses the…

Strategic competence, or the cognitive resources necessary for utilizing language knowledge, is widely recognized as an essential component of second language (L2) ability. However, research on strategic competence in the context of L2 speaking assessment has been limited, and findings have been inconsistent, making it challenging to discern the…

The purpose of this comparative study is to determine whether the linguistic input approach based on Krashen's (1989) comprehensible input (CI) and supported by Kolb's (2015) experiential learning (ELT) and Siemens' (2005) connectivism theory (CT) to improve eighth graders' Spanish speaking and writing linguistic proficiencies. Previous research…

This qualitative narrative research investigated successful cases of international students who actively verbally participate and speak up during academic or coursework discussions in the classrooms. More specifically, the aim of this narrative inquiry was to capture the lived and living experiences of English language learners (ELLs) navigating…

Many studies of non-native speech sound learning report a great deal of individual variability; some learners master the sounds of a second language with ease, while others struggle to perceive and produce sounds, even after years of learning the language. Although some contributions of phonological, auditory, or cognitive skills have been found…

Miniature language learning has been widely used to study the causality of language universals. However, factors that have been shown to affect language acquisition in other paradigms are understudied in miniature language learning, which calls into question results that claim to uncover universal biases. In this dissertation, I ask how the…
