This study investigated the effects of L2 pronunciation instruction on speech intelligibility and fluency, the relationship between intelligibility and fluency, and the extent to which utterance fluency can predict perceived fluency. Participants were 30 beginning adult EFL learners who received either segmental or suprasegmental instruction. Oral…

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)…

As part of the effort to elevate the oral English proficiency of Thai EFL learners, this paper explores university students' target-deviant English use in conversation, which should be systematically tackled in conversation teaching. Data examined included 41 two-three-minute video-recorded role-play dialogues from two English conversation…

While most empirical studies have investigated the improvement of learners' L2 spoken proficiency via speaking-related interventions, the present study examined the same topic through a different modality: listening. Ninety-five first-year tertiary-level students of English as a second language (ESL) in Hong Kong participated in this three-month…

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…

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…

The traditional focus of English phonetic teaching in China has consistently been on the segmental acquisition, which is mainly highlighting the pronunciation of vowels and consonants, while its suprasegmental knowledge in speech naturalness, coherence and understanding is relatively insufficient. In addition, Chinese students have a serious…

This study examines the relationship between German second language (L2) learners' awareness of the German lexical stress assignment system and their ability to accurately assign stress to cognate words with predictable lexical stress. Participants were 31 adult L2 German learners from three groups: native English speakers with a range of German…

High-stakes tasks may prevent language learners from performing successfully due to factors of "communicative stress" (Skehan, 1996, p. 52). Little research, however, has directly examined phonological patterns in learners' performances on low-stakes, medium-stakes, and high-stakes classroom tasks. The current study investigated the oral…

The main cause of pronunciation problems faced by EFL learners is their lack of a suprasegmental background. Most of those having oral comprehension and expression difficulties are unaware that their difficulty comes from their negligence of concepts of stress, pitch, juncture and linkers. While remedying stress problems, students should be taught…
