Purpose: The purpose of this study was to evaluate adaptation to the electropalatograph (EPG) from the perspective of consonant acoustics, listener perceptions, and speaker ratings. Method: Seven adults with typical speech wore an EPG and pseudo-EPG palate over 2 days and produced syllables, read a passage, counted, and rated their adaptation to…

This study was designed to investigate if persons who stutter differ from persons who do not stutter in the coproduction of different types of consonant clusters, as measured in the number of dysfluencies and incorrect speech productions, in speech reaction times and in word durations. Based on the Gestural Phonology Model of Browman and…

In the speech production model proposed by [Levelt, W. J. M., Roelofs, A., Meyer, A. S. (1999). A theory of lexical access in speech production. "Behavioral and Brain Sciences," 22, pp. 1-75.], syllables play a crucial role at the interface of phonological and phonetic encoding. At this interface, abstract phonological syllables are translated…

This paper presents a single-subject case study illustrating the need to closely examine effects of dialect from syllable position on l-colouring, and the effects of domain-initial strengthening in General American English. Most investigators report lighter /l/ tokens in syllable onsets and darker tokens in coda positions in isolated words. The…

Purpose: The purpose of this study was to examine the relationship between the types of speech errors that are produced by children with speech-sound disorders and the children's phonological awareness skills during their prekindergarten and kindergarten years. Method: Fifty-eight children with speech-sound disorders were assessed during the…

The authors studied the acquisition of nine #sC clusters in 30 Croatian-speaking phonologically disordered children, aged between 3;8-7;0 years, by analysing their renditions of target words elicited in response to visual stimuli presented on a computer screen. Results did not support the idea that a greater jump in sonority from C1 to C2 would…

The observation of a syllable frequency effect in naming latencies has been an argument in favor of a functional role of stored syllables in speech production. Accordingly, various theoretical models postulate that a repository of syllable representations is accessed during phonetic encoding. However, the direct empirical evidence for locating the…

A number of authors have presented data on the word length (measured in syllables) in the spontaneous speech of children across the developmental period. These data suggest a developmental trend of increasing length with age. The current study sought to examine this possibility in more detail. Conversational speech data from 320 children with…

This study investigated the acquisition of word initial s clusters of 3-5 year old Dutch children with phonological disorders. Within these clusters, sl was produced correctly most often, whereas sn and sx were the more difficult clusters. In cluster reductions, s+obstruent and sl clusters reduction patterns followed the Sonority Sequencing…

The study examined the functions served by consonant assimilation and reduplication in the speech of eight language disordered boys (ages 3 to 5). (Author)

This paper describes a neural model of speech acquisition and production that accounts for a wide range of acoustic, kinematic, and neuroimaging data concerning the control of speech movements. The model is a neural network whose components correspond to regions of the cerebral cortex and cerebellum, including premotor, motor, auditory, and…

This study investigates the influence of initial and final consonants /p, b, s, z/ on the duration of four vowels /I, i, u, ae/ in 64 CVC syllables uttered by eight speakers of English from the same dialect area. The CVC stimuli were presented to the subjects in a frame sentence from a master tape. Subjects repeated each sentence immediately after…

This study examined the effect of lexical aspect and phonology on regular past-tense production. Data are presented from a group of 31 children, mean age 33 months, with typical language development. A case study of a 50-month-old child with Specific Language Impairment (SLI) is also presented. Children imitated sentence pairs that included an…
