We examined what causes L1-L2 differences in sensitivity to prominence cues in discourse processing. Participants listened to recorded stories in segment-by-segment fashion at their own pace. Each story established a pair of contrasting items, and one item from the pair was rementioned and manipulated to carry either a contrastive or…

Eighty Japanese learners of English as a foreign language encountered 40 target words in one of four experimental conditions (three encounters, six encounters, three encounters with talker variability, and six encounters with talker variability). A picture-naming test was conducted three times (pretest, immediate posttest, and delayed posttest)…

This study tested the effects of hand-clapping to the rhythm of newly learned French words on the pronunciation of these words by 7- to 8-year-old Catalan children. In a short training experiment with a pre- and posttest design, 28 children either repeated cognate words in French (e.g. French "aspirateur," Catalan "aspirador"…

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…

This study explored the affective, behavioral, and cognitive engagement of 18 Iranian EFL learners with oral corrective feedback on lexical stress errors. The data were collected using questionnaires, pretests, posttests, and interviews. The questionnaire responses showed that the participants held various perceptions about direct feedback.…

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…

Perceptual grouping is fundamental to many auditory processes. The Iambic-Trochaic Law (ITL) is a default grouping strategy, where rhythmic alternations of duration are perceived iambically (weak-strong), while alternations of intensity are perceived trochaically (strong-weak). Some argue that the ITL is experience dependent. For instance, French…
