While much research has examined second language (L2) phonetic acquisition, less research has examined first language (L1) attrition in terms of the voice onset time (VOT) of voiceless stops. The current study examined L2 acquisition and L1 attrition in the VOT of word-initial voiceless stops among late English-Arabic and Arabic-English bilinguals…

Lexical tone languages like Mandarin Chinese require listeners to discriminate among different pitch patterns. A syllable spoken with a rising pitch (e.g. "b[i-acute]" 'nose') carries a different meaning than the same syllable spoken with a falling pitch (e.g. "b[i with grave]" 'arm'). For native speakers (L1) of a non-tonal…

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)…

Purpose: This research compared individuals from two first language (L1) backgrounds (English and Japanese) to determine how they may differ in their perception of Mandarin tones (Tones 1 vs. 2 [T1-T2], Tones 1 vs. 3 [T1-T3], Tones 1 vs. 4 [T1-T4], Tones 2 vs. 3 [T2-T3], Tones 2 vs. 4 [T2-T4], Tones 3 vs. 4 [T3-T4]) on account of their L1. Method:…

We examine the second language (L2) acquisition of variable Spanish word order by first language (L1) speakers of English via the acquisition of unaccusative and transitive predicates in various focus-related contexts. We employ two bimodal linguistic tasks: (1) acceptability judgment task (B-AJT) and (2) appropriateness preference task (B-APT).…

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…

In the present study, three groups of interpreter trainees were formed, two experimental groups, i.e., blended prosody instruction (BPI) and computer-assisted prosody training (CAPT), and one control group (CON). In this experiment the participants took part in a four-week teaching program for 16 sessions (60 minutes per session), i.e., 16 hours…

Few standardized language assessments are adapted to different cultural and linguistic contexts to assess children's first language (L1) abilities. We introduce the Ivorian Children's Language Assessment Toolkit for measuring phonological awareness, vocabulary, oral comprehension, and tone awareness in the Abidji, Attié, and Baoulé languages of…

This dissertation presents three studies that examined issues related to the production and the perception of pitch in a tone language. The first study examined linguistic contexts that may modulate consonant-induced pitch perturbations (CF0) in a tone language. Previous studies have produced mixed findings regarding the role of linguistic…

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)…

This study examines whether Japanese native (L1) listeners can implicitly learn stress pattern regularities, not present in their L1, after a brief auditory exposure. In the exposure phase, the participants listened to and repeated words bearing stress patterned after Latin, but with a highly restricted consonant inventory. They performed a…

This research analyzes the acoustic characteristics and conducts a perception test of Thai tones produced by Chinese learners learning Thai through the "Thai Tone Application". A comparison of Thai tones pronounced by 40 Chinese learners learning Thai at Nakhon Ratchasima Rajabhat University with 40 Thai native speakers was also…

Background: Children with developmental language disorder (DLD) demonstrate deficits in vocabulary development and novel word learning processes, which have been proposed to stem from their speech perception deficits. Aims: This study had two aims. The first was to evaluate the efficacy of an intervention incorporating a computer-based phonetic…

While it is well established that non-native speakers differ from native speakers in their perception and/or production of Mandarin lexical tones, empirical studies focusing on non-native "learners" are still limited. The objective of this study is to add to the current understanding of lexical tone perception by comparing native…

Supra-segmental features refer to various forms of intonation and how words and sentences are uttered. Such features challenge meaning and comprehension, too. Despite the importance of these features and their reported association with phonological awareness and linguistic comprehension, their effects on reading comprehension have not been…
