Spencer, Caroline; Davison, Kelsey E.; Boucher, Alyssa R.; Zuk, Jennifer – Language, Speech, and Hearing Services in Schools, 2022
Purpose: Beyond hallmark production deficits characterizing childhood apraxia of speech (CAS), largely attributed to disruption(s) in speech motor planning, children with CAS often present with co-occurring speech perception and language difficulties. Thus, careful consideration of the potential for speech perception difficulties to have cascading…

Sarah Alamri – ProQuest LLC, 2022
The Perceptual Assimilation Model (PAM) (Best, 1995) claims listeners directly perceive articulatory gestures of the vocal tract rather than acoustic/auditory signals. Accordingly, the articulatory similarities and discrepancies between native and non-native sounds determine the perceptual assimilation patterns of non-native sounds. This study…

Weerathunge, Hasini R.; Abur, Defne; Enos, Nicole M.; Brown, Katherine M.; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Gradual and sudden perturbations of vocal fundamental frequency (f[subscript o]), also known as adaptive and reflexive f[subscript o] perturbations, are techniques to study the influence of auditory feedback on voice f[subscript o] control mechanisms. Previous vocal f[subscript o] perturbations have incorporated varied setup-specific…

Cabbage, Kathryn L.; DeVeney, Shari L. – Topics in Language Disorders, 2020
Clinicians providing intervention for pediatric speech sound disorders (SSDs) have many treatment approach options from which to select. Because treatment needs vary across children based on many factors including the error type(s) present and patterns of deficit noted, these factors need to be considered early in the therapeutic process to find…

Sampaio, Marília; Masson, Maria Lúcia Vaz; de Paula Soares, Maria Francisca; Bohlender, Jörg Edgar; Brockmann-Bauser, Meike – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Smoothed cepstral peak prominence (CPPS) and harmonics-to-noise ratio (HNR) are acoustic measures related to the periodicity, harmonicity, and noise components of an acoustic signal. To date, there is little evidence about the advantages of CPPS over HNR in voice diagnostics. Recent studies indicate that voice fundamental frequency (F0)…

Xiaotong Xi; Peng Li; Pilar Prieto – Language Learning, 2024
This study investigates whether audiovisual phonetic training with hand gestures encoding visible or nonvisible articulation features has a differential impact on learning second language sounds. Ninety-nine Catalan-Spanish bilingual students were trained to differentiate English /ae/ and /[lambda]/, which differ in the visible lip aperture and…

Akiyo Hirai; Angelina Kovalyova – Language Learning & Technology, 2024
Speech-to-text applications have great potential for helping students with English language comprehension and pronunciation practice. This study explores the functionality of five speech-to-text (STT) applications (Google Docs voice typing tool, Apple Dictation, Windows 10 Dictation, Dictation.io [a website service], and "Transcribe" [an…

De Cock, Elien; Oostra, Kristine; Bliki, Lisa; Volkaerts, Anne-Sophie; Hemelsoet, Dimitri; De Herdt, Veerle; Batens, Katja – International Journal of Language & Communication Disorders, 2021
Background: Dysarthria is a common symptom following stroke and represents an important cause of functional impairment in stroke patients. A better characterization of dysarthria could facilitate differential diagnosis and optimize healthcare service distribution. Aim: To determine the speech characteristics, dysarthria type and severity in the…

The Relationship between Speech Perception and Speech Production in Children with Visual Impairments
Brouwer, Kyle; Gordon-Pershey, Monica – Journal of Visual Impairment & Blindness, 2021
The influence of visual impairment (i.e., blindness or low vision) on the development of children's speech sound production has undergone some speculation for over half a century. Children learn to produce speech sounds by utilizing and integrating several cognitive-linguistic and sensory-perceptual processes, which may include processing visual…

Wei Lai – ProQuest LLC, 2021
This dissertation examines how listeners' knowledge of interspeaker variability guides their generalization of perceptual learning in multi-talker listening. A series of perceptual learning experiments are conducted to evaluate whether listeners generalize what they have learned about a previous talker's production of sibilants and stop VOT to…

Chenausky, Karen V.; Gagné, Danielle; Stipancic, Kaila L.; Shield, Aaron; Green, Jordan R. – Journal of Speech, Language, and Hearing Research, 2022
Purpose: The purpose of this study was to investigate the association between perceived single-word speech severity and intelligibility in children with childhood apraxia of speech (CAS), with and without comorbid language impairment (LI), and to investigate the contribution of different CAS signs to perceived single-word speech severity and…

Peterson, Laura; Savarese, Christian; Campbell, Twylah; Ma, Zhigong; Simpson, Kenneth O.; McAllister, Tara – Language, Speech, and Hearing Services in Schools, 2022
Purpose: Although mobile apps are used extensively by speech-language pathologists, evidence for app-based treatments remains limited in quantity and quality. This study investigated the efficacy of app-based visual-acoustic biofeedback relative to nonbiofeedback treatment using a single-case randomization design. Because of COVID-19, all…

This study explored how university students in North America acquired the ability to express their career-related competencies in the context of a pre-professional career education program. We examined the intersection of happenstance learning theory (HLT) and experiential learning theory (ELT) to facilitate significant experiences that inspired…

Meghan Littlejohn; Edwin Maas – International Journal of Language & Communication Disorders, 2024
Background: 'Speech sound disorder' is an umbrella term that encompasses dysarthria, articulation disorders, childhood apraxia of speech and phonological disorders. However, differential diagnosis between these disorders is a persistent challenge in speech pathology, as many diagnostic procedures use symptom clusters instead of identifying an…
