Humans implicitly pick up on probabilities of stimuli and events, yet it remains unclear how statistical learning builds expectations that affect perception. Across 29 experiments, we examine the influence of task-irrelevant distributions--defined across acoustic frequency--on both tone detection in noise and tone duration judgments. The shape and…

Background: Effective classroom communication is key to shaping the learning environment and inspiring student engagement. And, it's not just what is said, but how it's said, that influences students. Yet, few (current or future) teachers receive education on vocal pedagogy. Aims: This study examined the impact of raising vocal awareness in…

Autistic adults are often perceived as having an atypical speech. The acoustic characteristics of these impressions prove surprisingly difficult to delineate, but one feature that does robustly emerge across different studies is higher pitch (F0 values) in autistic versus neurotypical individuals. However, there is no clear explanation why…

Prosody is an important indicator of reading development, but many teachers are unclear about how it can help students improve their reading fluency. Beyond demonstrating expressive or flowing reading, specific components of "reading prosody" can distinctly reveal how well word recognition and comprehension processes coalesce, providing…

When infants hear sentences containing unfamiliar words, are some language-world links (such as noun-object) more readily formed than others (verb-predicate)? We examined English learning 14-15-month-olds' capacity for linking referents in scenes with bisyllabic nonce utterances. Each of the two syllables referred either to the object's identity,…

Vocal imitation in English-speaking autistic individuals has been shown to be atypical. Speaking a tone language such as Mandarin facilitates vocal imitation skills among non-autistic individuals, yet no studies have examined whether this effect holds for autistic individuals. To address this question, we compared vocal imitation of speech and…

Purpose: Autistic individuals often face challenges perceiving and expressing emotions, potentially stemming from differences in speech prosody. Here we explore how autism diagnoses between groups, and measures of social competence within groups may be related to, first, children's speech characteristics (both prosodic features and amount of…

The purpose of this literature review was to synthesize research related to perceptions of choral tone and to provide implications for future research and praxis. Although considerable research exists on the topic of choral tone, choral music professionals have indicated contradictory philosophies of what makes "good" choral tone. To…

To investigate how a high risk for infant neurological impairment affects the quality of infant verbal interactions, and in particular properties of infant-directed speech, spontaneous interactions between 14 mothers and their 4.5-month-old infants at high risk for neurological disorders (7 female) were recorded and acoustically compared with…

Cross-linguistic studies found that reading comprehension correlates with oral reading prosody. The study examined whether text difficulty would be involved in oral reading prosody in orthographically deep languages like Mandarin. One hundred and three fourth-grade children were recruited in Taipei, Taiwan. Their oral reading prosody was elicited…

This cross-sectional study examines the sociopragmatic use of pitch and fluency features in requests among second language (L2) Chinese learners at two proficiency levels alongside native Chinese speakers. Twenty-eight L2 learners completed a 40-item oral discourse task with two types of request-making situations: (a) a high-imposition request to…

Friday sermons portray patterns of lexical cohesion which can demonstrate how effective communication is achieved. This study proposes a model of lexical cohesion that fits the spoken discourse of Friday sermons in the United Arab Emirates (UAE). To that end, a corpus of 25 sermons was analyzed to identify patterns of cohesion and show the impact…

We introduce the Corpus of Spoken Yiddish in Europe (CSYE), an Open Access digital language archive based on several hundred testimony interviews with Holocaust survivors from the USC Shoah Foundation. The testimonies are a uniquely rich source of information on all aspects of European Yiddish: its regional dialects, grammatical structures,…

Kindergarten principals' ethical leadership, preschool teachers' perceived organizational support, voice behavior, and work engagement are important components that promote high-quality development in kindergartens. In order to understand the relationship between the four variables, this study conducted an online survey of 819 preschool teachers.…

There is growing theoretical and empirical consensus for a role of awareness of suprasegmental phonology, also known as prosody, or the rhythmic elements of speech, in reading comprehension. Here we explore a potential mechanism by which this relation functions: awareness of how punctuation reflects prosody, for instance appreciating that a period…
