In a word learning experiment, 14- and 18-month-old infants are tested on their perceptual sensitivity to coda-consonant omissions. The results indicate that 14-month-olds are not sensitive to coda consonant omissions, showing a parallel with the omission of target coda consonants in early child language productions. At 18 months, infants are…

The objective of this study was to investigate the perceptual relevance of acoustic differences in vowels produced by 6 children between the ages of 9-13 years old with unilateral cochlear implants. Formant frequencies were estimated for 12 repetitions of vowels /hid/, /hed/, /haed/, /hud/, /hUd/, and /hAd/ produced by the children. The estimated…

The present article reports on the findings of a cross-sectional acoustic study of the production of the Spanish /e/-/ei/ contrast, as in "pena-peina" and "reno-reino," by native-English intermediate and advanced learners of Spanish. The acoustic parameter that distinguishes Spanish /e/ from /ei/ is formant change--/e/ is a…

Background: Swahili is widely spoken in East Africa, but to date there are no culturally and linguistically appropriate materials available for speech-language therapists working in the region. The challenges are further exacerbated by the limited research available on the typical acquisition of Swahili phonology. Aim: To describe the speech…

Many children experience recurrent acute otitis media (RAOM) in early childhood. In a previous study, 2-year-old children with RAOM were shown to have immature neural patterns for speech sound discrimination. The present study further investigated the consonant inventories of these same children using natural speech samples. The results showed…

Access to morphological structure during lexical processing has been established across a number of languages; however, it remains unclear which constituents are held as mental representations in the lexicon. The present study examined the auditory recognition of different noun types across 2 experiments. The critical manipulations were…

This study investigates consonant development in the spoken language of 269 children with hearing loss between 15 and 84 months of age. Children with mild, moderate, severe, and profound degrees of bilateral hearing loss, including those with cochlear implants, were evaluated. Speech samples from 885 different test sessions of 25-minute…

Theoretical approaches to the principles governing the coordination of speech gestures differ in their assessment of the contributions of biomechanical and perceptual pressures on this coordination. Perceptually-oriented accounts postulate that, for consonant-consonant (C1-C2) sequences, gestural timing patterns arise from speakers' sensitivity to…

Every language has its own rhythm. Unlike many other languages in the world, English depends on the correct pronunciation of stressed and unstressed or weakened syllables recurring in the same phrase or sentence. Mastering the rhythm of English makes speaking more effective. Experiments have shown that we tend to hear speech as more rhythmical…

Acquiring literacy establishes connections between the spoken and written system and modifies the functioning of the spoken system. As most evidence comes from on-line speech recognition tasks, it is still a matter of debate when and how these two systems interact in metaphonological tasks. The present event-related potentials study investigated…

A high percentage of individuals with dyslexia struggle to learn unfamiliar spoken words, creating a significant obstacle to foreign language learning after early childhood. The origin of spoken-word learning difficulties in this population, generally thought to be related to the underlying literacy deficit, is not well defined (e.g., Di Betta…

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,…

Juncture phonemes are very important sound structures in applied phonetics and phonology. Therefore, they must be taught properly to so that non-native students of English language can master the spoken form of the target language. In phonetics, they are the features in speech that enable a hearer to detect a beginning, word boundary, ups and…

This study is a systematic analysis of the information content of a wide range of distributional cues to word boundaries, individually and in combination, in naturally occurring child-directed speech across three languages (English, Polish, and Turkish). The paper presents a series of statistical analyses examining the relative predictive strength…

Current models of word production assume that words are stored as linear sequences of phonemes which are structured into syllables only at the moment of production. This is because syllable structure is always recoverable from the sequence of phonemes. In contrast, we present theoretical and empirical evidence that syllable structure is lexically…
