Background: Adults presenting with unrepaired cleft palate are not a rare occurrence in middle-income countries. However, many surgeons are hesitant to operate on these individuals because of the challenges in repairing the wide adult cleft palate, as well as concerns regarding any improvement in speech in older patients. Unfortunately, the…

Our purpose is to highlight the contributions of TalkBank initiatives to improved understanding of clinical impairments in adult and child speakers and examine remaining challenges and proposed solutions. We review the origins and development of TalkBank initiatives that have targeted a wide array of typical and atypical child and adult…

Purpose: Apraxia of speech (AOS) is a motor speech disorder affecting articulatory planning and speech programming. When AOS is the sole manifestation of neurodegeneration, it is termed primary progressive apraxia of speech (PPAOS). Recent work has shown that there are distinct PPAOS subtypes: phonetic, prosodic, and those that do not clearly…

Purpose: This study evaluates the initial efficacy of Chaining SPeech Lessons in Intensive Ten-minute Sessions (SPLITS), an alternative service delivery model for the Speech Motor Chaining treatment approach. We hypothesized that Chaining SPLITS would result in improvements in /[Voiced alveolar approximant]/ accuracy on syllables and untrained…

Background: Children born with cleft palate ± lip (CP ± L) are at risk of speech sound disorder (SSD). Up to 40% continue to have SSD at age 5-6 years. These difficulties are typically described as articulatory in nature and often include cleft speech characteristics (CSC) hypothesized to result from structural differences. In non-CP ± L SSD…

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…

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…

Aims: To describe typical phonological development of Brazilian Portuguese (BP)-speaking children, considering the following parameters: age of customary production, acquisition and mastery. Methods & Procedures: Data were collected from 857 children aged between 3 years and 8 years 11 months with typical language and speech development. The…

Purpose: Laryngeal high-speed videoendoscopy (LHSV) has been recognized as a highly valuable modality for the scientific investigations of vocal fold (VF) vibrations. In contrast to stroboscopic imaging, LHSV enables visualizing aperiodic VF vibrations. However, the technique is less well established in the clinical care of disordered voices,…

Covert contrast is the statistically reliable distinction between target language phonemes produced in the process of language acquisition that is nevertheless not perceived by a native speaker of that language. This paper examines the acquisition of contrasts in four Najdi Arabic fricatives, /s/, /[voiceless palato-alveolar fricative]/,…

Purpose: This review article critically interrogates the history and the current practice of standardized assessment in speech and language therapy. Speech and language assessments utilizing standardized linguistic norms are a critical tool for constructing disability and controlling disabled individuals. Such practices are rooted in a medical…

Purpose: This study aimed to (a) relate temporal patterning of articulation to functional speech outcomes in neurologically healthy and impaired speakers, (b) identify changes in temporal patterning of articulation in neurologically impaired speakers, and (c) evaluate how these changes can be modulated by speaking rate manipulation. Method:…

Introduction: Assessment of resonance characteristics is essential in research and clinical practice in individuals with velopharyngeal impairment. The purpose of this study was to systematically review correlations between auditory perceptual ratings and nasalance scores obtained by a nasometer in individuals with resonance disorders and to…

Purpose: The purpose of this tutorial is to guide practitioners to a critical praxis of speech, language, and hearing. This tutorial provides a foundational knowledge of critical theory as an approach to framing, conceptualizing, and interpreting phenomena and demonstrates its application to the speech, language, and hearing profession. Method:…

Purpose: Bilingual children often demonstrate a high rate of disfluencies, which might impact the diagnostic evaluation of fluency disorders; however, research on the rates and types of disfluencies in bilinguals' two languages is limited. The purpose of this research is to profile disfluencies of two types, stuttering-like disfluencies (SLDs) and…
