This article reports on two experiments that examine the computation of contrastive focus in Russian on the part of adult English-dominant heritage speakers and second language learners of Russian, in comparison with baseline monolinguals. The first experiment uses an acceptability judgment task to determine whether bilingual and monolingual…

Lexical stress is the contrast between strong and weak syllables within words. Ballard et al. (2012) examined the amount of stress contrastivity across adjacent syllables in word productions of typically developing three- to seven-year-olds and adults. Here, eight- to eleven-year-olds are compared with the adults from Ballard et al. using acoustic…

Purpose: The fine-tuning of linguistic prosody in later childhood is poorly understood, and its neurological processing is even less well studied. In particular, it is unknown if grammatical processing of prosody is left- or rightlateralized in childhood versus adulthood and how phonological working memory might modulate such lateralization.…

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…

Reading prosody is considered one of the essential markers of reading fluency, alongside accuracy and speed. The aim of our study was to investigate how development of reading prosody in Spanish children varies with sentence type and length. We compared primary school children from the third and fifth grades with an adult sample. Participants were…

Purpose: We aim to identify the possible sources for age-related differences in the perception of emotion in speech, focusing on the distinct roles of semantics (words) and prosody (tone of speech) and their interaction. Method: We implement the Test for Rating of Emotions in Speech (Ben-David, Multani, Shakuf, Rudzicz, & van Lieshout, 2016).…

Background: German participles are formed by a co-occurrence of prefixation and suffixation. While the acquisition of regular and irregular suffixation has been investigated exhaustively, it is still unclear how German children master the prosodically determined prefixation rule (prefix "ge-"). Findings reported in the literature are…

This study examined whether social bias manipulation can influence how naïve multiage listeners evaluate second language (L2) speech. Sixty native English-speaking listeners (Montreal residents) rated audio recordings of 40 Quebec French speakers of L2 English for five dimensions of oral performance (accentedness, comprehensibility, segmental…

Background: Sentence repetition is gaining increasing attention as a source of information about children's sentence-level abilities in clinical assessment, and as a clinical marker of specific language impairment. However, it is widely debated what the task is testing and therefore how informative it is. Aims: (1) To evaluate the effects of…

Late second language (L2) learners often struggle with L2 prosody, both in perception and production. This may result from first language (L1) interference or some property of how a second language functions in a late learner independent of what their L1 might be. Here we investigate prosody's role in determining information structure through…

Purpose: Accurate production of lexical stress within English polysyllabic words is critical for intelligibility and is affected in many speech-language disorders. However, models of speech production remain underspecified with regard to lexical stress. In this study, the authors report a large-scale acoustic investigation of lexical stress…

The current dissertation investigated segmental and prosodic aspects of first- (L1) and second-language (L2) speech production. Forty Korean-speaking adults and children varying in L2 experience (6 months-inexperienced vs. 6 years-experienced) as well as twenty age-matched native English speaking adults and children participated. Experienced…

This study reports an exploratory analysis of the age of arrival (AoA) effect on the production of second language (L2) prosody. Three groups of Mandarin-speaking immigrants (N = 10 in each group) with varying AoA in the United States and ten native speakers of English as controls participated in the study. All participants read a paragraph of…

Purpose: This study was aimed at determining the role of prosody and situational context in children's understanding of expressive utterances. Which one of these 2 cues will help children grasp the speaker's intention? Do children exhibit a "contextual bias" whereby they ignore prosody, such as the "lexical bias" found in other studies (M. Friend…

This study investigated multiple models for assessing oral reading fluency, including 1-minute oral reading measures that produce scores reported as words correct per minute (wcpm). We compared a measure of wcpm with measures of the individual and combined indicators of oral reading fluency (rate, accuracy, prosody, and comprehension) to examine…
