Purpose: Place and manner of articulation in American English-learning children's salient consonant-vowel-consonant-vowel (C[subscript 1]VC[subscript 2]V) target words (e.g., "baby," "bunny," and "cookie") were compared with their actual productions of these words. We hypothesized that target words with repeated place…

Since there are no systematic pauses delimiting words in speech, the problem of word segmentation is formidable even for monolingual infants. We use computational modeling to assess whether word segmentation is substantially harder in a bilingual than a monolingual setting. Seven algorithms representing different cognitive approaches to…

Purpose: This study aims at investigating the phonological development of the six guttural consonants of Jordanian Arabic, /[chi]/, /[voiced uvular fricative]/, /[voiceless pharyngeal fricative]/, /[voiced pharyngeal fricative]/, /[glottal stop]/, and /h/. Method: An articulation test is designed to involve two tasks: picture naming and…

Purpose: This study aimed to investigate the vocal characteristics of children with cerebral palsy (CP) and anarthria using the stage model of vocal development. Method: Vocal characteristics of 39 children with CP and anarthria around 4 years of age were analyzed from laboratory-based caregiver--child interactions. Perceptual coding analysis was…

Purpose: This study determined the time course of the emergence of prevocalic stop consonants in young children with cleft palate following surgical repair. Method: A total of 120 children in four cohorts from three institutions were followed from 12 to 24 months of age: (a) 24 with repaired cleft lip and palate (CLP), (b) 36 with repaired cleft…

Studies have suggested that multiple features influence letter knowledge across different orthographies. Arabic offers a unique opportunity to investigate the relations of letter properties on letter knowledge, but research on Arabic letter knowledge is scarce. This study was designed to investigate (a) letter frequency, (b) letter sequence, (c)…

Current theories of phonological development make contrasting predictions about the role of vocabulary growth and orthographic knowledge in the emergence of segmental phonological representations. Testing these predictions in children is made difficult by the metacognitive nature of tasks used to assess phonological representations. In this study,…

Purpose: Acoustic measurement of speech sounds requires first segmenting the speech signal into relevant units (words, phones, etc.). Manual segmentation is cumbersome and time consuming. Forced-alignment algorithms automate this process by aligning a transcript and a speech sample. We compared the phoneme-level alignment performance of five…

Reading acquisition is based on a set of preliteracy skills that lay the foundation for future reading abilities. Phonological awareness--the ability to identify and manipulate the sound units of oral language--has been reported to play a central role in reading acquisition. However, current evidence is mixed with respect to its universal…

This paper addresses how input variability in the adult phonological system is mastered in the output of young children in Akan, a Kwa language spoken in Ghana, involving variability between labio-palatalized consonants and front rounded vowels. The high-frequency variant involves a complex consonant which is expected to be mastered late, while…

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: This article reports on the effectiveness of a novel tablet-based approach to phonological intervention and compares it to a traditional tabletop approach, targeting children with phonologically based speech sound disorders (SSD). Method: Twenty-two Portuguese children with phonologically based SSD were randomly assigned to 1 of 2…

Two methods of decoding instruction were compared. Participants were kindergartners who knew letter sounds but could not decode nonwords, M = 5.6 years. The segmented phonation treatment taught students to convert graphemes to phonemes by breaking the speech stream ("sss -- aaa -- nnn") before blending. The connected phonation treatment…

This study investigates the phonological awareness of a Turkish monolingual and a Turkish-English bilingual child in Turkish. As a case study, the main focus of this study is to explore whether a bilingual advantage exists in phonological processing. Theories of bilingualism and empirical data led to the prediction that the bilingual participant…

Purpose: Generalizations can be made about the order in which speech sounds are added to a child's phonemic inventory and the ways that child speech deviates from adult targets in a given language. Developmental and disordered speech patterns are presumed to reflect differences in both phonological knowledge and skilled motor control, but the…
