This study was driven by the need to understand the mechanisms underlying Lidcombe Program treatment efficacy. The aim of the present study was to extend existing data exploring whether stuttering reductions observed when children successfully treated with the Lidcombe Program are associated with restricted language development. Audio recordings of 10-min parent-child conversations at home were transcribed verbatim for 11 pre-school-age children with various stuttering severities. Language samples from three assessments-pre-treatment, 9 and 18 months after beginning treatment-were analysed using SALT software for lexical diversity, utterance length and sentence complexity...

Recent studies by Bastiaanse and colleagues found that time reference is selectively impaired in people with nonfluent agrammatic aphasia, with reference to the past being more difficult to process than reference to the present or to the future. To account for this dissociation, they formulated the PAst DIscourse LInking Hypothesis (PADILIH), which posits that past reference is more demanding than present/future reference because it involves discourse linking. There is some evidence that this hypothesis can be applied to people with fluent aphasia as well...

While growing evidence reports changes in language use in non-demented individuals with Parkinson's disease (PD), the presence and nature of the deficits remain largely unclear. Researchers have proposed that dysfunctioning fronto-basal ganglia circuit results in impaired grammatical processes, predicting qualitatively similar language impairments between individuals with PD and agrammatic Broca's aphasia, whereas others suggest that PD is not associated with language-specific grammatical impairment. In addition, there is a paucity of research examining syntactic production in PD at the sentence-level...

Numerous investigations have identified weaknesses in speech processing and language skills in children with dyslexia; however, little is known about these abilities in children with reading difficulties (RD). The primary objective of this investigation was to determine the utility of auditory speech processing tasks in differentiating children with RD from those with typical reading skills. It was hypothesized that children, who perform below grade level in reading, would also show poorer performance on both dichotic listening and sentence repetition tasks because of the reciprocal influences of deficient auditory speech processing and language abilities...

The aim of the present study was to investigate whether the degree of incongruity between contextual information and a target sentence influences the extent to which irony is understood in individuals with right-frontal-hemisphere damage (RHD). A psycholinguistic paradigm was used, allowing us to assess whether impairment in irony understanding is likely to be due to insensitivity (i.e. difficulty in capturing or detecting relevant contextual information) to relevant contextual information or to difficulties in integrating contextual information...

Mixed and inconsistent findings have been reported across languages concerning grammatical morphology in speakers with Autism Spectrum Disorders (ASD). Some researchers argue for a selective sparing of grammar whereas others claim to have identified grammatical deficits. The present study aimed to investigate this issue in 26 participants with ASD speaking European French who were matched on age, gender and SES to 26 participants with typical development (TD). The groups were compared regarding their productivity and accuracy of syntactic and agreement categories using the French MOR part-of-speech tagger available from the CHILDES...

This study examined changes in speech motor control across a movement transition between sounds within a motor learning task in children with apraxia of speech (CAS) and typical development (TD). It was investigated whether oral articulator movement was refined with practice and whether practice gains generalized to words not included in the practice session. A total of 16 children (ages 5-6) with CAS (n = 8) and TD (n = 8) participated in this study. Novel and real word tokens were produced at three time points...

There is substantial evidence that a speaker's accent, specifically an unfamiliar accent, can affect the listener's comprehension. In general, this effect holds true for both adults and children as well as those with typical and impaired language. Previous studies have investigated the effect of different accents on individuals with language disorders, but children with speech sound disorders (SSDs) have received little attention. The current study aims to learn more about the ability of children with SSD to process different speaker accents...

The aim of our study was to examine the extent to which linguistic approaches to sentence comprehension deficits in aphasia can account for differential impairment patterns in the comprehension of wh-questions in bilingual persons with aphasia (PWA). We investigated the comprehension of subject and object wh-questions in both Turkish, a wh-in-situ language, and German, a wh-fronting language, in two bilingual PWA using a sentence-to-picture matching task. Both PWA showed differential impairment patterns in their two languages...

The central aim of this experiment was to compare acoustic parameters, formant frequencies and vowel space area (VSA), in adolescents with hearing-impaired (HI) and their normal-hearing (NH) peers; for kinematic parameters, the movements of vocal organs, especially the lips, jaw and tongue, during vowel production were analysed. The participants were 12 adolescents with different degrees of hearing impairment. The control group consisted of 12 age-matched NH adolescents. All participants were native Chinese speakers who were asked to produce the Mandarin vowels /a/, /i/ and /u/, with subsequent acoustic and kinematic analysis...

The rehabilitation of speech disorders benefits from providing visual information which may improve speech motor plans in patients. We tested the proof of concept of a rehabilitation method (Sensori-Motor Fusion, SMF; Ultraspeech player) in one post-stroke patient presenting chronic non-fluent aphasia. SMF allows visualisation by the patient of target tongue and lips movements using high-speed ultrasound and video imaging. This can improve the patient's awareness of his/her own lingual and labial movements, which can, in turn, improve the representation of articulatory movements and increase the ability to coordinate and combine articulatory gestures...

The aims of this study were to: 1) compare voicing contrast in speakers with Parkinson disease (PD) and healthy controls by comparing the separation of voice onset time (VOT) distributions of voiced and voiceless stop consonants and 2) to determine whether the administration of dopaminergic medication affected VOT separation in speakers with PD. Data from a previous study by Fisher and Goberman (2010) were used to compare the VOT measures obtained from a group of speakers with PD with both ON and OFF medication, and a group of healthy controls...

In this article, we explore the naming skills of a bilingual English-Norwegian speaker diagnosed with Primary Progressive Aphasia, in each of his languages across three different speech contexts: confrontation naming, semi-spontaneous narrative (picture description), and conversation, and at two points in time: 12 and 30 months post diagnosis, respectively. The results are discussed in light of two main theories of lexical retrieval in healthy, elderly speakers: the Transmission Deficit Hypothesis and the Inhibitory Deficit Theory...

Many studies reported the presence of language impairments in children and adolescents with Klinefelter syndrome (KS). However, the first stage of their language development has been scarcely studied. The present study aimed to describe the spontaneous communicative production of 18-month-old children with KS, in comparison with that of typically developing (TD) male peers, aiming to verify the existence of different early communicative skills in both vocal and gestural modality and to identify the presence of possible associations with their later vocabulary size...

In this article, disfluent word-repetitions are analysed in cluttered and control speech. The main questions are the following: (1) Do different functions of word-repetitions occur in different ratio in cluttered and control speech? (2) Are there any differences between PWC and control speakers in durational parameters of disfluent word-repetitions? Results show that there are differences between the two groups of speakers in the types of word-repetitions, and in their durational parameters. In cluttered speech, the most frequent type of repetitions were covert self-repairs while in control speech canonical repetitions are dominated...

This paper describes word-initial (WI) rhotic cluster development in Slovenian 4-year-olds. Data for /l/ and WI singleton /r/ serve as comparisons. Participants were 19 children with typical development (TD) and 13 with more protracted phonological development (PPD). A single-word list included 15 WI /r/-clusters, 9 /l/-clusters and 3 singleton /r/s and /l/s each. Results showed significantly higher match (accuracy) levels for rhotics in the TD group. Among rhotic clusters, TD children showed highest match levels for labial clusters, and the PPD group, for /dr/...

Rhotic clusters are complex structures segmentally and prosodically and are frequently one of the last structures acquired by Portuguese-speaking children. This paper describes cross-sectional data for word-initial (WI) rhotic tap clusters in typically developing 3-4- and 5-year-olds in Portugal. Additional information is provided on WI /l/ as a singleton and in clusters. A native speaker audio-recorded and transcribed single words in a story-telling task. Results for WI rhotic clusters show an age effect consistent with previous research on European Portuguese...

This study investigates the developmental patterns of acquisition of word-initial (WI) /r/-clusters in children speaking Hungarian, typically developing (TD) or with protracted phonological development (PPD). Comparison data were also analysed for WI singleton /r/ and /l/. Participants were 191 children (aged 3;0-5;11) divided into three age groups (3, 4, 5 years), and further subdivided into TD and PPD subgroups on the basis of Whole Word Match scores (WWM). Acoustic analyses of perceptually accurate clusters were conducted to investigate epenthesis...

The current paper describes acquisition of word-initial (WI) trilled /r/ in clusters and as a singleton in 60 Bulgarian 3-5-year-olds with typically developing (TD) versus protracted phonological development (PPD). A native speaker audio-recorded and transcribed single-word responses to a picture-naming task (110 words) that included eight words with WI rhotic clusters and two with WI singleton /r/. Accuracy was significantly higher in the TD groups and for the PPD groups, by age. Mismatch patterns varied: the PPD cohort had the most varied patterns although the younger children with PPD showed more /r/ deletion in clusters, and the TD groups and 5-year-olds with PPD more substitutions for /r/...
