Background: Developmental dysarthria is a motor speech impairment commonly characterized by varying levels of reduced speech intelligibility. The relationship between intelligibility deficits and acoustic vowel space among these individuals has long been noted in the literature, with evidence of vowel centralization (e.g., in English and…

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…

Background: Acquired apraxia of speech (AOS) involves speech-production deficits on both the segmental and suprasegmental levels. Recent research has identified a non-linear interaction between the metrical structure of bisyllabic words and word-production accuracy in German speakers with AOS, with trochaic words (strong-weak stress) being…

'Dysarthria' is a group of motor speech disorders resulting from a disturbance in neuromuscular control. Most individuals with dysarthria cope with communicative restrictions due to speech impairments and reduced intelligibility. Thus, language-sensitive measurements of intelligibility are important in dysarthria neurological assessment. The…

Without data on speech accuracy of Vietnamese-English speakers, speech-language pathologists (SLPs) are unable to assess accurately this population for speech sound disorders. This study explored the heretofore uninvestigated speech accuracy and use of Vietnamese-English bilingual individuals residing in the USA. Participants included six…

Acquisition of oral English verb morphology presents difficulties for bilinguals, learners of EFL and English-speaking monolingual children with specific language impairment. This study aimed to identify challenging English verb inflections among sixth grade speakers of Arabic (N = 85) and Hebrew (N = 86) using an elicited oral narrative task, and…

Purpose: To examine how interaction contributes to phonological acquisition in bilingual children in order to determine what constitutes typical development of bilingual speech sound inventories. Method: Twenty-four children, ages 3-4, were included: eight bilingual Spanish-English-speaking children, eight monolingual Spanish speakers, and eight…

This study investigated the acquisition of word initial s clusters of 3-5 year old Dutch children with phonological disorders. Within these clusters, sl was produced correctly most often, whereas sn and sx were the more difficult clusters. In cluster reductions, s+obstruent and sl clusters reduction patterns followed the Sonority Sequencing…
