This systematic literature review aimed to study the effects of early reading interventions in early grades. Specifically, interventions in the early stages affect letter-sound recognition, phonemic awareness, and word identification. Many students may fail to reach the end-of-the-year standards, even with strong classroom teaching. Intervention…

For students to be able to read and comprehend, they must first develop phonological awareness, the ability to recognize and manipulate the segments of sound in words. To develop this ability, students must be able to identify the following: individual sounds (phonemes) in words; print letters of the alphabet; and corresponding sounds for each…

Purpose: Secretion bubbling on the superior aspect of the velopharyngeal (VP) valve typically occurs with a small VP opening during production of oral pressure consonants. The use of high-speed nasopharyngoscopy has shown correlation between the bubbling frequency and the acoustics captured with the nasal microphone of the nasometer. The purpose…

Multisyllabic words constitute a large portion of children's vocabulary. However, the relationship between phonological neighborhood density and English multisyllabic word learning is poorly understood. We examine this link in three, four and six year old children using a corpus-based approach. While we were able to replicate the well-accepted…

Purpose: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects bulbar functions including speech and voice. Voice onset time (VOT) was examined in speakers with ALS in early and late stages to explore the coordination of the articulatory and phonatory systems during speech production. Method: VOT was measured in nonword…

Purpose: The primary aim was to assess whether children have difficulty distinguishing similar-sounding novel words. The secondary aim was to assess what task characteristics might hinder or facilitate perceptual discrimination. Method: Three within-subjects experiments tested ninety-nine 3- to 5-year-old children total. Experiment 1 presented two…

Studies have suggested that multiple features influence letter knowledge across different orthographies. Arabic offers a unique opportunity to investigate the relations of letter properties on letter knowledge, but research on Arabic letter knowledge is scarce. This study was designed to investigate (a) letter frequency, (b) letter sequence, (c)…

Background: Speech and language are interconnected systems, and language disorder often co-occurs with childhood apraxia of speech (CAS) and non-CAS speech sound disorders (SSDs). Potential trade-off effects between speech and language in connected speech in children without overt language disorder have been less explored. Method: Story retell…

Production of certain English phonemes relies heavily on effort from the abdominal region, and under-utilization of this region by second language English speakers can create difficulties pronouncing these sounds. In particular, production of long vowel/diphthong sounds requires sustained abdominal contraction to maintain the length of these…

The purpose of this qualitative study was to describe the verbal interventions produced by teachers to support pupils' development of orthographic knowledge through invented spelling in three research-based intervention conditions: conventional (C condition), proximal (P condition), and progressive complexification (PC condition). We recorded six…

Purpose: Real-time altered feedback has demonstrated a key role for auditory feedback in both online feedback control and in updating feedforward control for future utterances. The aim of this study was to examine adaptation in response to temporal perturbation using real-time perturbation of ongoing speech. Method: Twenty native English speakers…

A challenge for listeners is to learn the appropriate mapping between acoustics and phonetic categories for an individual talker. Lexically guided perceptual learning (LGPL) studies have shown that listeners can leverage lexical knowledge to guide this process. For instance, listeners learn to interpret ambiguous /s/-/[esh]/ blends as /s/ if they…

Purpose: The goal of this study was to explore the relationships among vocal effort, extrinsic laryngeal muscle activity, and vocal tract length (VTL) within healthy speakers. We hypothesized that increased vocal effort would result in increased suprahyoid muscle activation and decreased VTL, as previously observed in individuals with vocal…

Preschoolers born preterm are at an increased risk for adverse neurodevelopmental outcomes; however, the impact of preterm birth on speech development has not been fully investigated. The primary objective of this study was to document the conversational speech production abilities of preschoolers born preterm via speech sample analysis. A…

The acquisition of Italian stop consonants by Mandarin Chinese-speaking learners has hardly been investigated. This study was designed to fill this gap. To investigate Chinese learners' acquisition patterns of Italian voiced and voiceless stops, a perception experiment and a production experiment were conducted. Twenty Mandarin Chinese-speaking…
