Children with hearing loss often attend inclusive preschool classrooms aimed at improving their spoken language skills. Although preschool classrooms are fertile environments for vocal interaction with peers, little is known about the dyadic processes that influence children's speech to one another and foster their language abilities and how these…

In human languages, different speech sounds can be contextual variants of a single phoneme, called allophones. Learning which sounds are allophones is an integral part of the acquisition of phonemes. Whether given sounds are separate phonemes or allophones in a listener's language affects speech perception. Listeners tend to be less sensitive to…

Background: Respiratory muscle impairment following cervical spinal cord injury (CSCI) may lead to reduced voice function, although the individual variation is large. Voice problems in this population may not always receive attention since individuals with CSCI face other, more acute and life-threatening issues that need/receive attention.…

Purpose: Diagnostic recommendations for acquired apraxia of speech (AOS) have been contradictory concerning whether speech sound errors are consistent or variable. Studies have reported divergent findings that, on face value, could argue either for or against error consistency as a diagnostic criterion. The purpose of this study was to explain…

Children's speech development begins in infancy. The pattern of this development has been explored in studies over a number of years using a range of research methodology and approaches to investigation. A systematic review of the existing literature was carried out to determine the collective contribution of this literature to our understanding…

A special feature of class interaction discourse relates to typical elements of context. The elements of the context include the participants, the background, the topic, the nature of the message, and the message tone. Teachers are more dominant to organize the course of teaching and learning activities, such as topic selection, topic development,…

This article studies the cognitive dynamics of stancetaking in the discourse situations associated with risky behaviour and perilous decisions. The objective of this work is to find out what linguistic and cognitive mechanisms are used by speech participants to conceptualise a discourse situation as a situation of risk, and analyse the ways the…

In this article, I present my view on the significant developments and theoretical/empirical tipping points in nonverbal and verbal deception and lie detection from the last 30 years and on prospects for future research in this domain. I discuss three major shifts in deception detection research: (a) From observing target persons' nonverbal…

Purpose: Conversational entrainment is the tendency for individuals to modify their behavior to more closely converge with the behavior of their communication partner and is an important aspect of successful interaction. Evidence of entrainment in adults is robust, yet research regarding its development in children is sparse. Here, we investigate…

Willingness to communicate in a second language (L2 WTC) is a learner's volitional participation in oral communication using L2. Previous research has expended considerable attention to the stable, trait-like disposition of learners' L2 WTC, while less focus has been accorded to the complex nature of variations in L2 WTC on multiple timescales.…

I investigated the emotional coordination (matching, synchrony, completion and attunement) between infant and paternal facial expressions of emotion in the course of paternal questions addressed to infants during their spontaneous dyadic interaction. Eleven infant-father dyads were observed during their natural interactions at home from the second…

Purpose: The purpose of this study was to investigate whether speech perception would reflect small latency changes in subcortical speech representation. Method: Twelve native Japanese listeners participated in the experiment. Those listeners participated in speech identification task and auditory brainstem response (ABR) measurement using…

The objective of this study was to examine the links between prosodic features of paternal Infant-Directed Speech (IDS) and child characteristics. Pitch variability measures were extracted from the speech samples of 50 fathers during unstructured play with their two-year-old children. Evidence for a link between child receptive language ability…

Sign languages present particular challenges to language assessors in relation to variation in signs, weakly defined citation forms, and a general lack of standard-setting work even in long-established measures of productive sign proficiency. The present article addresses and explores these issues via a mixed-methods study of a human-rated…

For the past five years, the Alutiiq Museum and Archaeological Repository has been documenting intricacies of the Alutiiq language with the help of Elder speakers and a grant from the National Science Foundation (#1360839). The project's primary focus has been recording vocabulary, grammar, and ways of speaking for this threatened Native Alaskan…
