Recent findings have revealed that very preterm neonates already show the typical brain responses to place of articulation changes in stop consonants, but data on their sensitivity to other types of phonetic changes remain scarce. Here, we examined the impact of 7-8 weeks of extra-uterine life on the automatic processing of syllables in 20 healthy…

Purpose: This study compared performance on the Syllable Repetition Task (SRT) by preschoolers with diverse speech and language abilities to identify underlying impairments in speech processes. Method: Three groups of 13 children ages 4 and 5 years with (a) typically developing (TD) speech and language, (b) speech sound disorder (SSD), and (c)…

Purpose: The aim of this study was to investigate developmental and noise-induced changes in central auditory processing indexed by event-related potentials in typically developing children. Method: P1, N2, and N4 responses as well as mismatch negativities (MMNs) were recorded for standard syllables and consonants, frequency, intensity, vowel, and…

The aim of this experiment was to examine the preattentive processing of syllables in 9-11-year-old children with dyslexia and matched controls using the Mismatch Negativity (MMN), an auditory Event-Related brain potential (ERP) related to preattentive discrimination. Children were presented with a sequence of syllables that included standards…

In a noisy environment, visual perception of articulatory movements improves natural speech intelligibility. Parallel to phonemic processing based on auditory signal, visemic processing constitutes a counterpart based on "visemes", the distinctive visual units of speech. Aiming at investigating the neural substrates of visemic processing in a…

Recent research has shown that adults can implicitly learn artificial phonotactics constraints from experience producing syllables that contain those constraints, and that this learning is reflected in their speech errors. However, second-order constraints in which the placement of a consonant depends on another characteristic of the syllable…

Purpose: This study investigated the network of brain regions involved in overt production of vowels, monosyllables, and bisyllables to test hypotheses derived from the Directions Into Velocities of Articulators (DIVA) model of speech production (Guenther, Ghosh, & Tourville, 2006). The DIVA model predicts left lateralized activity in inferior…

Two word-spotting experiments are reported that examine whether the Possible-Word Constraint (PWC) is a language-specific or language-universal strategy for the segmentation of continuous speech. Examined cases where the residue was either a CVC syllable with a Schwa or a CV syllable with a lax vowel. Showed that the word-spotting results…

In this paper we report on an adult male participant with a rare form of progressive speech degeneration. We present acoustic phonetic data on his vowel and consonant production, and describe his prosody and syllable structure. We suggest possible phonological analyses of his speech, concluding that a gestural approach to phonology best…

Speech production studies have shown that the phonological form of a word is made up of phonemic segments in stress-timed languages (e.g., Dutch) and of syllables in syllable timed languages (e.g., Chinese). To clarify the functional unit of mora-timed languages, the authors asked native Japanese speakers to perform an implicit priming task (A. S.…

This paper argues that Chomsky's and Halle's restriction on the features [+high, +low] are too severe; that this restriction is inconsistent with the generative treatment of affricates, laterally-released stops, and prenasalized stops; and that the restriction is inconsistent with the notion that linguistic descriptions are abstract theories about…

The pronunciations of children do not merely represent accidental misses with respect to adult pronunciation. Children employ substitutions and deletions in highly systematic ways; child pronunciations reflect a set of simplification strategies. The major common processes of both normal and abnormal child phonology result in simplification of…

In "The Sound Pattern of English," Chomsky and Halle maintain that the phonetic representation of most words can be generated from underlying forms and a small set of rules. Since these underlying forms are frequently close to the traditional spelling, we may hypothesize that literate native speakers share comparable internalized rules which…

The ability of 78 disabled and nondisabled second, third, and fourth graders to discriminate between syllables that were vowels and syllables beginning with liquid and plosive consonants was studied. The results suggest that children with reading disabilities experience a deficit in processing phonemic information within syllables. (SLD)
