Prosody is considered one of the most challenging aspects of second language (L2) speech acquisition. This study explores the role of working memory (WM) in the perception and production of English nuclear accent (NA) by L1 Spanish learners. It focuses on both default and non-default patterns of NA placement in English. Twenty-four participants…

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…

We investigated the role of cue weighting, second language (L2) proficiency, and L2 daily exposure in L2 learning of suprasegmentals different from the first language (L1), using eye-tracking. Spanish monolinguals, English-Spanish learners, and Mandarin--Spanish learners saw a paroxytone and an oxytone verb (e.g., "FIRma-firMÓ"…

The primary aim of this study was to investigate prosodic prominence across three groups of Sylheti-English bilinguals: first-generation who arrived as adults, first-generation who arrived as children, and second-generation, i.e., born in the United Kingdom to parents who grew up in Bangladesh. To measure prominence, f0, duration, and intensity…

Two acoustic studies of voice onset time (VOT) in sibilant-stop (ST) consonant clusters, produced by first language (L1) speakers of Polish, are presented. In the first, a baseline study of L1 Polish comparing ST clusters with initial singleton stops, a small degree of VOT shortening after /s/ was found for /p/, but not /t/. The second study…

It has been proposed that second language (L2) learners differ from native speakers in processing due to either influence from their native language or an inability to integrate information from multiple linguistic domains in a second language. To shed new light on the underlying mechanism of L2 processing, we used an event-related potentials…

Purpose: Prosodic sensitivity, or the ability to perceive suprasegmental features of speech such as lexical tone in Cantonese and lexical stress in English, has been recognized as an essential component of reading acquisition. However, the specific pathways by which it influences reading comprehension remain unclear. This study evaluates how…

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…

While monolingual speakers can use contrastive pitch accents to predict upcoming referents, bilingual speakers do not always use this cue predictively in their L2. The current study examines the role of recent exposure for predictive processing in native German (L1) second language learners of English (L2). In Experiment 1, participants followed…

We investigated how native and fluent users of English segment continuous speech and to what extent they use sound-related and structure-related cues. As suggested by the notion of multi-competence, L1 users are not seen as ideal models with perfect command of English, and L2 users not as lacking in competence. We wanted to see how language…

This dissertation investigated the acoustic and articulatory correlates of lexical stress in Mandarin second language (L2) learners of English, as well as in first language (L1) speakers. The present study used a minimal pair respective to stress location (e.g., OBject versus obJECT) obtained from a publicly available Mandarin Accented English…

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…

The Sylheti Bangla, a variety of Bangla language is primarily spoken in the Sylhet District of Bangladesh, Barak Valley of Assam, Tripura, especially in North Tripura. The systematic perusal on English spoken by Sylheti Bangla speakers demonstrates that it carries a huge difference with English (RP) specially in respect to pronunciation, syllable…

This study investigated bilingualism effects on the production of focus in 5- to 9-year-old Cantonese-English bilingual autistic children's L1 Cantonese, compared to their monolingual autistic peers as well as monolingual and bilingual typically developing children matched in nonverbal IQ, working memory, receptive vocabulary and maternal…

Prosody is crucial for language comprehension because it highlights underlying structures. This study explores whether prosody facilitates "memory recall" to the same extent in L1 and L2, and whether memory recall is poorer in L2 or whether language-specific differences can mitigate L2 processing difficulties. Nineteen Greek learners of…
