Languages differ in the importance of acoustic dimensions for speech categorization. This poses a potential challenge for second language (L2) learners, and the extent to which adult L2 learners can acquire new perceptual strategies for speech categorization remains unclear. This study investigated the effects of extensive English L2 immersion on…

This dissertation examines heritage language learners of Spanish enrolled in university Spanish courses, focusing on their strategic use of suprasegmental speech features in two speaking tasks. The research investigates attitudes' influence on heritage language learners' speech production in different task types. Participants engaged in two…

In this study, 118 native speakers of Japanese watched 48 separate video clips in which a teacher provided recasts on phonological or lexical errors to students in Portuguese, a language with which the participants were unfamiliar. In the video clips, six recast characteristics were manipulated: length, segmentation (segmented/whole), prosodic…

This study compared holistic and analytic marking methods for their effects on parameter estimation (of examinees, raters, and items) and rater cognition in assessing speech act production in L2 Chinese. Seventy American learners of Chinese completed an oral Discourse Completion Test assessing requests and refusals. Four first-language (L1)…

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 study focuses on the development of L2 prosody and, in particular, whether different aspects can affect each other. Finnish-speaking learners of Swedish took part in a pronunciation and oral skills course and were recorded for various speaking tasks before and after the experimental intervention. Read-aloud declarative sentences (statements)…

With Conversation Analysis (CA) insights, this paper examines the textbooks used to teach oral English communication to Thai EFL learners in secondary schools. In an attempt to raise the awareness of features of naturally-occurring conversation and help increase the learners' exposure to these features, two textbook series, hereafter A and B, were…

The present study aimed to examine the contributions of two separate Pinyin skills and oral vocabulary to Chinese word reading of 70 third graders in a U.S. Mandarin Immersion program where Pinyin was introduced at Grade 3. Hierarchical regression analyses showed that Pinyin initial-final spelling--the skill to spell Chinese syllables using Pinyin…

Prosody is a linguistic feature in spoken English that is complex yet plays an important role in oral communication. Nevertheless, many EFL pronunciation classes in Thailand have not adequately emphasized the importance and functions of prosody to learners. This research study aims to investigate effect of an oral fluency instructional method…

This paper examines whether a web-based training on English discourse intonation leads to better spontaneous speech quality for Mandarin Chinese speakers who reside in the U.S. and in China. The four-week fully online training consisted of meta-instruction videos as well as listening and speaking activities, including instant visual pitch contour…

The research concerns the problem of mastering English voice production skills in oral interpretation of the authentic belles-lettres texts. The purpose of the paper is to present the teaching algorithm of training future English language and literature teachers' skills in decoding and orally interpreting verbalised English voice prosodic…

This study investigated the effects of temporal distribution of practice on the learning and retention of Mandarin tonal word production. Eighty native English-speaking adults with no prior knowledge of a tonal language participated in this study. They were randomly assigned to four experimental conditions varying in intersession interval (ISI)…

Although videos are now used pervasively in English as a Foreign Language settings, most existing literature centers on learners as knowledge receivers or passive video viewers (Lialikhova, 2014; Fisher & Frey, 2015; Bakar et al., 2019). Rarely do studies involving videos engaged learners as knowledge generators or active, self-directed…

This study investigated how adult second language (L2) learners of Mandarin Chinese use knowledge of phonological and lexical statistical regularities when acoustic information is insufficient for word recognition. A gating task was used to test intermediate L2 learners at two time points across a semester of classroom learning. Native Mandarin…

The current study investigates the effects of more explicit versus more implicit corrective feedback on beginner Mandarin learners' perception and production of Mandarin tones. The effects of oral corrective feedback have been extensively investigated for various domains of second language acquisition (see Mackey & Goo, 2007). For phonological…
