In this study, we investigated developmental aspects of eye movements during reading of three languages (English, German, and Finnish) that vary widely in their orthographic complexity and predictability. Grapheme-phoneme correspondence rules are rather complex in English and German but relatively simple in Finnish. Despite their differences in…

The schwa sound, as the most frequent in English, is a near constant in words of three syllables or longer in academic texts. As linguistic research has shown, it characteristically recurs in rhythmic alternation with stressed syllables, contributing to a word's distinctive sound shape. The location of strong stress and therefore schwa is often…

Purpose: Speech-language pathologists (SLPs) working within the pediatric field will find themselves working with school-age children and consequently collaborating with teaching staff. Knowledge of the links between language, speech, and literacy can support and inform successful collaboration between the SLP and the teacher and their shared goal…

Multiple acoustic dimensions signal speech categories. However, dimensions vary in their informativeness; some are more diagnostic of category membership than others. Speech categorization reflects these dimensional regularities such that diagnostic dimensions carry more "perceptual weight" and more effectively signal category membership…

The goal of this study was to investigate non-adjacent consonant sequence patterns in target words during the first-word period in infants learning American English. In the spontaneous speech of eighteen participants, target words with a Consonant-Vowel-Consonant (C[subscript 1]VC[subscript 2]) shape were analyzed. Target words were grouped into…

This dissertation investigates language-specific acoustic and aerodynamic phenomena in language contact situations. Whereas most work on second language and bilingual phonology has focused on individual consonants and vowels, this project examines patterns of coarticulation in the two languages of Spanish-English and French-English bilingual…

This study employed a targeted phonetic instruction to explore the mechanisms that underpin second language (L2) phonetic acquisition. Broadly, two general approaches to phonetic acquisition have been previously proposed. A segmental approach suggests that learners acquire a series of individual, discrete phonemes (e.g., Flege, 1995), while a…

The present study investigated whether morphological processing in reading is influenced by the orthographic consistency of a language or its morphological complexity. Developing readers in Grade 3 and skilled adult readers participated in a reading aloud task in four alphabetic orthographies (English, French, German, Italian), which differ in…

The study analysed spectral and tongue shape dynamics of voiceless alveolar and postalveolar fricatives produced by ten children learning Scottish English. Synchronised ultrasound tongue imaging data and acoustic data were used to characterise children's productions of the phonemic contrast. Six children had consistently accurate productions of…

Purpose: This study used perceptual and acoustic measures to examine the time course of speech adaptation after the attachment of electromagnetic sensor coils to the tongue, lips, and jaw. Method: Twenty native English speakers read aloud stimulus sentences before the attachment of the sensors, immediately after attachment, and again 5, 10, 15,…

Purpose: This study aimed to examine whether abstract knowledge of word-level linguistic prosody is independent of or integrated with phonetic knowledge. Method: Event-related potential (ERP) responses were measured from 18 adult listeners while they listened to native and nonnative word-level prosody in speech and in nonspeech. The prosodic…

This article summarises the linguistic base of initial reading and spelling in English for the benefit of teachers and others engaged in education who need explicit understanding of parts of the linguistic base in order to teach initial literacy accurately. The aspects covered are those most relevant to children entering formal schooling: spoken…

This study examined how intervention dose frequency affects phonological acquisition and generalization in preschool children with speech sound disorders (SSD). Using a multiple-baseline, single-participants experimental design, eight English-speaking children with SSD (4;0 to 5;6) were split into two dose frequency conditions (4…

Non-native phoneme perception can be challenging for adult learners. This article explores two routes to strengthening early representations of non-native targets: perceptual training, which focuses on auditory discrimination of novel contrasts, and articulatory training, which highlights the articulatory gestures of non-native categories. Of…

Purpose: The purpose of this study was to examine the diagnostic accuracy of traditional measures of phonological ability developed for monolingual English-speaking children with their bilingual peers in both English and Spanish. We predicted that a composite measure, derived from a combination of English and Spanish phonological measures, would…
