Speech and music emerge from a spectrum of nested motor and perceptual coordination patterns across timescales of brief movements to actions. Intuitively, this nested clustering in movements should be reflected in sound. We examined similarities and differences in multimodal, multiscale coordination of speech and music using two complementary…

This study examined conversational turn-taking when reading scripted dialogue versus having a spontaneous conversation. When reading, listeners waited until speakers' turns had been completed before moving to start their own turns, and gap lengths between turns were longer than those of spontaneous, natural conversation. Theatrical performance…

Through providing an external support to speech, gesture observation may benefit a student's learning in a variety of areas, including narrative comprehension. Across two studies, we investigated factors that could moderate when gestures are most beneficial to narrative comprehension, including gesture type, task difficulty, and age, in order to…

This study investigates in a joint action setting a well-established effect in speech production, cumulative semantic interference, an increase in naming latencies when naming a series of semantically related pictures. In a joint action setting, two task partners take turns naming pictures. Previous work in this setting has demonstrated that…

Australian Indigenous sign languages are predominantly used by hearing people as a replacement for speech in certain cultural contexts. In some circumstances sign is used alongside speech, and in others it may replace speech altogether. This article provides a window on some of the articulatory dimensions of these sign languages by examining the…

Naming spaces is a human act and reflects traces of the culture and social group to which the person who names a place belongs, either in spoken or sign languages. This article presents an analysis of the toponyms in Libras that name the cities of the state of Acre. The toponyms were stored in digital files proposed by Sousa and Quadros (2019),…

Purpose: The goal of this study was to present vocal aerodynamic measurements from pediatric and adult participant pools. There are a number of anatomical changes involving the larynx and vocal folds that occur as children age and become adults. Data were collected using two methods of noninvasive aerodynamic assessment: mechanical interruption…

Identifying speech requires that listeners make rapid use of fine-grained acoustic cues--a process that is facilitated by being able to see the talker's face. Face masks present a challenge to this process because they can both alter acoustic information and conceal the talker's mouth. Here, we investigated the degree to which different types of…

From the point of word formation, the phenomenon of lexical blending is a common productive process, entailing the notion of combination of lexemes in so many languages. In the vast majority of literature on blends, they preserve a linear formation of segments with a shortening of both lexemes. However, in sign languages where morphological…

This study examines the second language (L2) development of variable /s/-weakening in the spontaneous speech of L2 learners of Spanish who studied abroad in either Dominican Republic, where /s/-weakening is widespread, or central Spain, where /s/-weakening is much less common. Learners' realizations of /s/ were coded impressionistically and…

Class conversation in the learning process has important benefits and can facilitate the learning process, students' understanding of the material and create a close relationship between teachers and students. This study describes the classroom conversation strategies implemented in junior high schools, namely preliminary, core and final at…

Children with partially intelligible speech and language difficulties are often provided with speech-generating devices (SGDs) to support their spoken communication. However, little is known about how SGDs can be used best to facilitate language development. This study evaluated the effects of a conversation-based intervention using SGDs, on the…

Purpose: The aim of the study was to assess the susceptibility to energetic and informational masking in patients with single-sided deafness (SSD) with one normal-hearing (NH) ear and a cochlear implant (CI) in the contralateral ear, understand the effect on speech recognition when spatially separating noise and speech maskers, and investigate the…

A prominent hypothesis holds that by speaking to infants in infant-directed speech (IDS) as opposed to adult-directed speech (ADS), parents help them learn phonetic categories. Specifically, two characteristics of IDS have been claimed to facilitate learning: "hyperarticulation," which makes the categories more "separable," and…

As our understanding of the construct of oral communication (OC) has evolved, so have the possibilities of computer technology undertaking the delivery of tests that measure this ability. It is paramount to understand to what extent such developments lead to accurate, comprehensive, and useful assessment of OC. In this paper, we discuss five…
