An often overlooked but fundamental issue for any comprehensive model of visual-word recognition is the representation of diacritical vowels: Do diacritical and nondiacritical vowels share their abstract letter representations? Recent research suggests that the answer is "yes" in languages where diacritics indicate suprasegmental…

This research investigated whether observing beat gesture and hearing contrastive accenting with novel words enhances their learning in early childhood and whether these effects differ by sex in light of sex differences in the pace of language development. Fifty-three 3- to 5-year-old boys and girls learned pairs of novel words with contrasting…

Whereas many scholars have emphasized the relative importance of "comprehensibility" as an ecologically valid goal for L2 speech training, testing, and development, eliciting listeners' judgments is time-consuming. Following calls for research on more efficient L2 speech rating methods in applied linguistics, and growing attention toward…

Children are adept at learning their language's speech-sound categories, but just how these categories function in their developing lexicon has not been mapped out in detail. Here, we addressed whether, in a language-guided looking procedure, 2-year-olds would respond to a mispronunciation of the voicing of the initial consonant of a newly learned…

Our motivation was to examine how toddler (2;6) and adult speakers of American English prosodically realize information status categories. The aims were three-fold: (1) to analyze how adults phonologically make information status distinctions; (2) to examine how these same categories are signaled in toddlers' spontaneous speech; and (3) to analyze…

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…

This study explores the effects of embodied prosodic training on the production of non-native French front rounded vowels (i.e. /y, ø, oe/) and the overall pronunciation proficiency. Fifty-seven Catalan learners of French practiced pronunciation in one of two conditions: one group observed hand gestures embodying prosodic features of the sentences…

Explicit pronunciation instruction enhances production of intelligible, comprehensible, and fluent second language (L2) speech. Additionally, task-based instruction (TBI) enhances the production of segmentals and suprasegmentals, and promotes awareness of L2 forms in pronunciation. Since most previous research on TBI in L2 pronunciation learning…

The present dissertation analyzed speech production and perception in early heritage Spanish-English bilingual children. Specifically, I investigated how perception and production of lexical stress develops in bilingual children. Current models of second language (L2) speech perception do not include heritage bilinguals or suprasegmental aspects…

Prosody signals important aspects of meaning, and hence, is crucial for language comprehension and learning, yet remains under-investigated in second-language (L2) processing. The present electrophysiology study investigates the use of prosody to cue information structure, in particular, the use of contrastive pitch accent (L+H*) to define the set…

This study explores the use of F0, intensity and duration in the production of two types of prominences in French: primary accent with duration as the main acoustic cue, and secondary accent with F0 and intensity as acoustic cues. These parameters were studied in 13 children using a cochlear implant (CI) and 17 children with a normal hearing (NH),…

Purpose: Research has shown that observing hand gestures mimicking pitch movements or rhythmic patterns can improve the learning of second language (L2) suprasegmental features. However, less is known about the effects of hand gestures on the learning of novel phonemic contrasts. This study examines (a) whether hand gestures mimicking phonetic…

This study investigates the perception and production of a specific type of metaphoric gesture that mimics melody in speech, also called "pitch gesture," in the learning of L2 suprasegmental features. In a between-subjects design, a total of 106 participants with no previous knowledge of Chinese were asked to observe (Experiment 1) and…

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…

This study examined pinyin (the official phonetic system that transcribes the lexical tones and pronunciation of Chinese characters) invented spelling and English invented spelling in 72 Mandarin-speaking 6th graders who learned English as their second language. The pinyin invented spelling task measured segmental-level awareness including…
