This dissertation delves into second language acquisition, sociophonetic variation, and speech perception, investigating how prior linguistic experiences and exposure to regional variations in a second language influence the decoding of dialectal linguistic cues. It aims to enhance the understanding of words pronounced with different phones and…

This study examines the effects of task complexity on second language (L2) pronunciation accuracy and global pronunciation measures in pronunciation-unfocused tasks and assesses the relationship between acoustic and listener-based pronunciation measures. Eighty-two Catalan/Spanish learners of English performed simple and complex versions of a…

This report examines the potential impacts of task and proficiency on listener judgments of intelligibility, comprehensibility, and accentedness in L2 Spanish. This study extends Huensch and Nagle ["Language Learning," 71, 626-668, (2021)], who explored the partial independence among the global speech dimensions for speech samples taken…

Purpose: Phonetic training has been found to be an effective way on second language (L2) learning, but the evidence is not conclusive regarding the effectiveness of different instructional approaches and possible interactions between language learners, training features, and outcome measures. This study aims to meta-analyze existing studies to…

Speech perception research has commonly relied on untrained listeners to provide impressionistic judgments of second language (L2) speech, and training listeners has been rare. The current study therefore explores the implications of training novice listeners (NLs) to rate accented speech. A total of 60 listeners were recruited, 30 who remained…

Although current approaches to second language (L2) pronunciation underscore that instruction should concentrate on pronunciation features that help learners be more intelligible (and not necessarily more native like), there is little empirical evidence as to what those features are, especially in languages other than English. To address this gap,…

We examined the naturalistic pronunciation development of two groups of L2 speakers over 10 years. Initially, 50 beginner ESL students participated in production tasks; despite attrition, the tasks were administered eight more times. Here we report listener judgements of accentedness, comprehensibility and fluency for the remaining six Mandarin…

This article examines language classrooms as communicative settings for learners' development of sociolinguistic competence involving target language variation in a study abroad context. Specifically, it investigates how two Spanish teachers in Peru imparted knowledge of the social and contextual appropriateness of local linguistic variants that…

Perception of second language (L2) speakers and their speech is known to be influenced both by phonetic and by sociolinguistic factors. The existing body of scholarly research on L2 speech perception, however, is overwhelmingly focused on Indo-European languages, raising doubts about the generalizability of existing sociolinguistic, phonetic,…

This mixed-methods study investigated Chinese tertiary-level students' perceptions of different English accents existing in mainland China. Also examined were their perception changes and factors that contributed to their perception changes. An electronic questionnaire survey was employed to investigate the general trend and the possible…

Purpose: This study aimed to examine the effects of sentence context, accent strength, and second language (L2) listening proficiency on word recognition accuracy and transcription time among Chinese learners of English for Pakistani-accented English. Method: Speech stimuli included 48 isolated words and 48 highly constraining sentences, each…

This study examines creative uses of emerging image-based social media for informal language learning. Adopting the ecological concept of affordances, it investigates new technological features on Instagram and TikTok and how they are utilised as resources for language learning. Using public data of Instagram photo/video and TikTok video posts,…

This sequential explanatory mixed-methods study provides a radical transformative framing of the power language dynamic in K-6 classrooms in the U.S. The quantitative phase of the study determined the relationship between teachers' self-efficacy and the use of linguistically responsive techniques in the classroom. The study's qualitative phase…

To examine speaker role models (SRMs) in second language acquisition (SLA), this study explored the sociolinguistic "English as a lingua franca" (ELF) perspective targeting international intelligibility. Thus, it examined the way ELF learners align with self-selected English speakers and anonymous (audio-recorded) English speakers as…

This study aimed to answer an ongoing validity question related to the use of nonstandard English accents in international tests of English proficiency and associated issues of test fairness. More specifically, we examined (1) the extent to which different or shared English accents had an impact on listeners' performances on the Duolingo listening…
