Aims: To investigate the developmental trajectory of the rate and perceptual assessment of oral diadochokinesis (DDK) in typically developing children compared with adults. Also to examine the characteristics of DDK productions in children with speech sound disorders (SSD) and the relationship between DDK production and percentage of consonants…

Purpose: Speech sound disorder (SSD) is one of the major speech disorders in school-age children. Given the heterogeneity in terms of subtypes within SSD, there is a need to develop techniques for a quick identification of these subtypes. Furthermore, given the paucity of studies from children with SSD from Cantonese-speaking homes and a noted…

This study investigates phonological characteristics of Korean monolingual children with phonological disorders (PD), using data from 13 children aged 3.6 to 5.9, and compares the analyses of single-word productions (SW) to those of conversational speech (CS). Phonological analyses include overall percentage of consonants correct (PCC), individual…

Purpose: Automatic speech analysis (ASA) and automatic speech recognition systems are increasingly being used in the treatment of speech sound disorders (SSDs). When utilized as a home practice tool or in the absence of the clinician, the ASA system has the potential to facilitate treatment gains. However, the feedback accuracy of such systems…

Purpose: The purpose of this study was to quantify changes in acoustic distinctiveness in two groups of talkers with Parkinson's disease as they modify across a wide range of speaking rates. Method: People with Parkinson's disease with and without deep brain stimulation and older healthy controls read 24 carrier phrases at different speech rates.…

Purpose: Children with speech sound disorders feature prominently on the caseloads of speech-language pathologists working in schools, with many receiving services once or twice weekly for 20-30 min. This study compared the outcomes of services provided twice weekly for 30 min to those provided 4 times weekly for 15 min to examine their…

Background: The articulatory accuracy of patients with dysarthria is one of the most affected speech dimensions with a high impact on speech intelligibility. Behavioural treatments of articulation can either involve direct or indirect approaches. The latter have been thoroughly investigated and are generally appreciated for their almost immediate…

Purpose: This study describes a phonetic complexity-based approach for speech intelligibility and articulatory precision testing using preliminary data from talkers with amyotrophic lateral sclerosis. Method: Eight talkers with amyotrophic lateral sclerosis and 8 healthy controls produced a list of 16 low and high complexity words. Sixty-four…

The aim of this article is to examine speech-language pathologists' (SLPs) knowledge and competence using Percentage of Consonants Correct (PCC). Participants were recruited through posts on social media and message boards for the American Speech-Language-Hearing Association (ASHA) Special Interest Groups. In addition, surveys were emailed via the…

Background: In the last decade, a large number of children with cleft lip and palate have been adopted to Sweden. A majority of the children were born in China and they usually arrive in Sweden with an unoperated palate. There is currently a lack of knowledge regarding speech and articulation development in this group of children, who also have to…

Purpose: This case-control study sought to determine if (a) children with childhood apraxia of speech (CAS), other speech sound disorders (SSDs), and typical development would perform differently on a procedural learning assessment and (b) whether grammatical ability would impact group differences. Method: Communication, motor, and procedural…

The auditory neural representations of infants can easily be studied with electroencephalography using mismatch experimental designs. We recorded high-density event-related potentials while 3-month-old infants were listening to trials consisting of CV syllables produced with different vowels (/bX/ or /gX/). The consonant remained the same for the…

Background: The assessment of intelligibility is an essential part of establishing the severity of a speech disorder. The intelligibility of a speaker is affected by a number of different variables relating, "inter alia," to the speech material, the listener and the listener task. Aims: To explore the impact of the number of…

Background: Research regarding expressive language performance in children born with cleft palate is sparse. The relationship between articulation/phonology and expressive language skills also needs to be further explored. Aims: To investigate verbal competence in narrative retelling in 5-year-old children born with unilateral cleft lip and palate…

A multimodal approach combining acoustics, intelligibility ratings, articulography and surface electromyography was used to examine the characteristics of dysarthria due to cerebral palsy (CP). CV syllables were studied by obtaining the slope of F2 transition during the diphthong, tongue-jaw kinematics during the release of the onset consonant,…
