This study aims to identify the pronunciation issues with English fricatives that undergraduate students encounter as a result of the intricate link between the English letter and sound. The purpose of this study is to gather comprehensive data regarding students' pronunciation difficulties in terms of the degree of difficulty associated with each…

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…

Rhythmic structure in speech is characterized by sequences of stressed and unstressed syllables. A large body of literature suggests that speakers of English attempt to achieve rhythmic harmony by evenly distributing stressed syllables throughout prosodic phrases. The question remains as to how speakers plan metrical structure during speech…

In this experiment, we examined whether beginning readers benefit more from grapheme-phoneme decoding (GPD) than from whole-syllable decoding (WSD) instruction in learning to read and write words. Sixty Brazilian Portuguese-speaking first graders (M age = 6 years 1 month) who knew letter names but could not read or write words were randomly…

In this article, the relationship between alphabet knowledge and reading development will be explored. Key topics will include how alphabet knowledge is not only a predictor for future reading success, but also how letters and their sounds serve as a bridge from a pre-alphabetic phase into a partial alphabetic phase, and beyond. Since each phase…

Purpose: One of the central questions in speech production research is to what degree certain structures have an inherent difficulty and to what degree repeated encounter and practice make them easier to process. The goal of this article was to determine the extent to which frequency and sonority distance of consonant clusters predict production…

For students to be able to read and comprehend, they must first develop phonological awareness, the ability to recognize and manipulate the segments of sound in words. To develop this ability, students must be able to identify the following: individual sounds (phonemes) in words; print letters of the alphabet; and corresponding sounds for each…

Purpose: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects bulbar functions including speech and voice. Voice onset time (VOT) was examined in speakers with ALS in early and late stages to explore the coordination of the articulatory and phonatory systems during speech production. Method: VOT was measured in nonword…

Production of certain English phonemes relies heavily on effort from the abdominal region, and under-utilization of this region by second language English speakers can create difficulties pronouncing these sounds. In particular, production of long vowel/diphthong sounds requires sustained abdominal contraction to maintain the length of these…

Yamdena is an Austronesian language of eastern Indonesia. Although many language materials are available, the language has received very little scientific attention. In this article, I present the Yamdena corpus, which includes glossed legacy materials and original fieldwork. I also give an up-to-date introduction to Yamdena grammar, sketching its…

Programs for teaching English reading, especially for students with dyslexia, and educational practice standards often recommend instruction on dividing polysyllabic words into syllables. Syllable division is effort intensive and could inhibit fluency when reading in text. The division strategies might still be useful if they work so consistently…

This review describes a computational approach for modeling the development of speech motor control in infants. We address the development of two levels of control: articulation of individual speech sounds (defined here as phonemes, syllables, or words for which there is an optimized motor program) and production of sound sequences such as phrases…

Learning a spoken language requires learning a phonological inventory and phonotactics, or the sequences of phonemes possible in the language. Laboratory investigations of phonotactic learning include tongue-twister studies that show that speech errors respect artificial phonotactic constraints, for example that /k/ never appears as a syllable…

Learning to read English is more difficult than in most other alphabetic languages. It sometimes seems there are not reliable rules for linking letters with sounds. Teaching students all of the letter patterns they may find in texts is no simple task. Students struggle processing the sounds in words, so even words with simple spellings are…

We examined full-term and preterm infants' perception of frequent and infrequent phonotactic pairings involving sibilants and liquids. Infants were tested on their preference for syllables with onsets involving /s/ or /?/ followed by /l/ or /r/ using the Headturn Preference Procedure. Full-term infants preferred the frequent to the infrequent…
