Background: Classification systems in healthcare support shared understanding of conditions for clinical communication, service monitoring and development, and research. Children born with cleft palate with or without cleft lip (CP+/-L) are at high risk of developing cleft-related speech sound disorder (SSD). The way cleft-related SSD is…

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…

Background: Cleft lip and palate is one of the most common oral and maxillofacial deformities associated with a variety of functional disorders. Cleft palate speech disorder (CPSD) occurs the most frequently and manifests a series of characteristic speech features, which are called cleft speech characteristics. Some scholars believe that children…

Purpose: The purposes of this review article were to provide an introduction to and "bird's-eye" overview of the current evidence base for treatment of childhood apraxia of speech (CAS), identify some gaps and trends in this rapidly growing literature, and formulate some future research directions, in order to advance the evidence base…

Purpose: The purpose of the present study was to explore the ability of Hebrew-speaking children with childhood apraxia of speech (CAS) to produce lexical stress. Method: A total of 36 children aged between 4 and 7 years, 18 children with CAS, and 18 typically developing (TD) children participated in the study. All children completed language and…

Purpose: In a previous publication, we observed that maximum speech performance in a nonclinical sample of young adult speakers producing "alternating" diadochokinesis (DDK) sequences (e.g., rapidly repeating "pataka") was associated with cognitive control: Those with better cognitive switching abilities (i.e., switching…

Background: In response to the call for papers under the theme "What is in a name" proposed by the Scientific Child Speech Committee of the International Association of Communication Sciences and Disorders (IALP), the current paper discusses taxonomy and its relation to speech sound disorders (SSD) from a cross-linguistic perspective.…

Purpose: Neurogenic speech and language disorders--such as acquired apraxia of speech (AOS) and aphasia with phonemic paraphasia (APP)--are often misdiagnosed due to similarities in clinical presentation. Word syllable duration (WSD)--a measure of average syllable length in multisyllabic words--serves as a proxy for speech rate, which is an…

Purpose: Limited research exists assessing speech perception in school-age children with speech sound disorder (SSD) and childhood apraxia of speech (CAS); despite early evidence that speech perception may lead to error-prone motor planning/programming. In this study, we examine speech perception performance in school-age children with and without…

Autistic people who cannot speak risk being underestimated. Their inability to speak, along with other unconventional behaviors and mannerisms, can give rise to limiting assumptions about their capacities, including their capacity to acquire literacy. In this preregistered study, we developed a task to investigate whether autistic adolescents and…

Reading difficulty (RD) is associated with phonological deficits; however, it remains unknown whether the phonological deficits are different in children and adults with RD as reflected in foreign speech perception and production. In the current study, using functional Near-infrared spectroscopy (fNIRS), we found less difference between Chinese…

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: Speech--Music Therapy for Aphasia (SMTA), a method that combines speech therapy and music therapy, is introduced as a treatment method for childhood apraxia of speech (CAS). SMTA will be evaluated in a proof-ofprinciple study. The first case study is presented herein. Method: SMTA was evaluated in a study with a single-subject…

Purpose: Connected speech analysis has been effectively utilized for the diagnosis and disease monitoring of individuals with Alzheimer's disease (AD). Existing research has been conducted mostly in monolingual English speakers with a noticeable lack of evidence from bilinguals and non-English speakers, particularly in non-European languages.…

Literacy skills can assist in the navigation and enjoyment of adult life. For individuals who have reached adulthood without strong literacy skills, opportunities for continued literacy learning are few. Redesigning AAC technologies to support literacy skill development could extend literacy learning opportunities for adults with developmental…
