A group of children with dyslexia (mean ages 9 and 14 years) was studied, together with group of children without dyslexia matched for age. Participants were monolingual native speakers of the Bosnian language with transparent orthography. In total, the diagnostic tests were performed with 41 children with dyslexia and 41 nondyslexic children. The…

Studies of connected speech have repeatedly shown that the contextual predictability of a word is related to its phonetic duration; more predictable words tend to be produced with shorter duration, when other factors are controlled for (Aylett & Turk, 2004, 2006; Bell et al., 2003; Bell, Brenier, Gregory, Girand, & Jurafsky, 2009; Gahl,…

This dissertation makes two contributions, one empirical, the other theoretical. Empirically, the dissertation deepens our understanding of the lifecycle and behavior of the preaspirated stop, an extremely rare phonological feature. I show that in most confirmed cases, preaspirated stops develop from earlier voiceless geminate stops, less commonly…

The purpose of this study was to compare early speech and language development of children with and without cleft lip and/or palate (CLP) in the US and Slovakia from 6 to 24 months of age. Thirty-two children from the US (eight with CLP and eight noncleft) and Slovakia (eight with CLP and eight noncleft) participated in this study. The children…

The present study examines the effects of training native Japanese speakers in the production of American /r/ using spectrographic visual feedback. Within a modified single-subject design, two native Japanese participants produced single words containing /r/ in a variety of positions while viewing live spectrographic feedback with the aim of…

Purpose: The purpose of this study was to describe normative and validation data on the Intelligibility in Context Scale (ICS; McLeod, Harrison, & McCormack, 2012c) for English-speaking children. Method: The ICS is a 7-item, parent-report measure of children's speech intelligibility with a range of communicative partners. Data were collected…

Despite developments in phonology over the last few decades, models of verbal working memory make reference to phoneme-sized phonological units, rather than to the features of which they are composed. This study investigates the influence on short-term retention of such features by comparing the serial recall of lists of syllables with varying…

Increasingly, Chinese students are pursuing their studies abroad in English-speaking countries, such as the USA, the UK, Australia, and New Zealand. Despite the fact that they have studied English as a compulsory subject for a number of years and have passed multiple English proficiency tests, many still find it is difficult to communicate well in…

Purpose: To undertake a community (nonclinical) study to describe the speech of preschool children who had been identified by parents/teachers as having difficulties "talking and making speech sounds" and compare the speech characteristics of those who had and had not accessed the services of a speech-language pathologist (SLP). Method:…

The primary focus of this research study was to examine the benefit of a using a multimodal approach to speech sound correction with preschool children. The approach uses the auditory, tactile, and kinesthetic modalities and includes a unique, interactive visual focus that attempts to provide a visual representation of a phonemic category. The…

The purpose of this work is to investigate the role of three articulatory parameters (tongue position, jaw position and tongue grooving) in the production of /s/. Six normal speakers' speech was perturbed by a palatal prosthesis. The fricative was recorded acoustically and through electromagnetic articulography in four conditions: (1) unperturbed,…

This study aims to explore how the markedness effect shapes Mandarin slips of the tongue with respect to nasals in syllable-final positions. Data were collected via natural speech and elicitation tasks from 35 participants' reading of 346 test items. Three hundred and eight slips in Mandarin from natural data and 360 slips from elicited data were…

The precise structure of speech sound representations is still a matter of debate. In the present neurobiological study, we compared predictions about differential sensitivity to speech contrasts between models that assume full specification of all phonological information in the mental lexicon with those assuming sparse representations (only…

Debuccalization is a weakening phenomenon whereby various consonants reduce to laryngeals. Examples include Spanish s-aspiration (s becomes h word-finally) and English t-glottalization (t becomes glottal stop syllable-finally). Previous analyses of debuccalization view it as a lenition process that deletes or manipulates formal phonological…

The influence of coarticulation cues on spoken word recognition is not yet well understood. This acoustic/phonetic variation may be processed early and recognized as sensory noise to be stripped away, or it may influence processing at a later prelexical stage. The present study used event-related potentials (ERPs) in a picture/spoken word matching…
