As one of the Celtic languages, Irish is among the few languages in the world that employ word initial mutations (IMs) in order to express grammatical functions. IMs express grammatical information by a way of systematic alternation of minimal phonological contrasts, which closely links segmental phonology to grammatical morphology (Irish also employs final consonant palatalization as a grammatical marker, but this will not be the focus of our paper). The overwhelming majority of Irish speakers are bilingual (with English), and virtually all Irish-speaking children grow up with varying degrees of exposure to and use of English in the home...

The contribution of the phonological working memory to the Non-Word Repetition (NWR) task is well established, but growing evidence also suggests a valuable underlying role of oro-motor abilities. Assuming that NWR involves output implementation mediated by the speech motor system, the study aimed to develop a novel Italian NWR task of disyllabic and trisyllabic items. The task, for the first time, was composed using each Italian speech sound. The study also aimed to investigate the reliability proprieties of the task (test-retest, intra-rater, inter-rater), internal consistency, concurrent and construct validity, and to collect normative data for pre-school children...

Demonstratives (e.g. here, that, these) and personal pronouns are early developing components of language, which are often impaired in young children with autism spectrum disorder (ASD). Additionally, demonstrative and personal pronoun use are linked to joint attention and language ability early in life for individuals with ASD. Fragile X syndrome (FXS) is a genetic disorder with a significant amount of overlap in its behavioural phenotype with ASD. The present study examined demonstrative and personal pronoun production during a conversation sample in adolescent boys with ASD and adolescent boys with FXS with a co-diagnosis of ASD (FXS+ASD)...

Although much of the research on morphology and aphasia has focused specifically on the distinction between regular and irregular verb production, individuals with aphasia often present with differences in performance within these categories. While these within-category differences are relatively understudied, they have the potential to inform our understanding of the morphological processing system and treatment protocols for morphological impairment. The present study examines how morphophonological patterns in English impact past-tense production within the categories of regular and irregular verbs based on errors of an individual with acquired morphological impairment...

We aim at determining whether 7-year-old Italian-speaking children with Specific Language Impairment (SLI): (1) have problems with the production of wh- questions; (2) display a subject/object asymmetry in producing which- and who questions; (3) attempt to simplify questions, especially which- questions; (4) have difficulties with movement and verbal agreement in wh- questions. We elicited subject and object who and which NP questions in 10 children with SLI (M = 7;2), in 10 chronological age (CA)-matched controls (M = 7;2) and 10 language-matched controls (M = 5;2)...

Morphosyntax is one of the most impaired aspects of language development in children with Down syndrome. The present study aimed to assess the emergence of multiword utterances in this population. Sixteen Italian-speaking children with Down syndrome were followed from 36 to 48 months of age. Data derived from an analysis of their spontaneous productions showed that although the mean productivity of multiword utterances increased over the three time points (36, 42 and 48 months), different growth patterns of early syntactic development could be identified: (1) null or marginal development; (2) a gradual increase in multiword production over time; (3) an increase in the production of more complex multiword utterances and a decrease or inverted U-shaped profile in the production of simpler multiword productions; (4) an inverted U-shaped profile in multiword productions...

The aim of this research was to explore how preschool-aged children with phonological impairment (PI) realise grammatical morphemes across different phonological contexts (i.e. singleton consonant, consonant cluster, syllable), conditions of finiteness and individual morpheme types. Factors accounting for children's realisation of grammatical morphemes were also examined. Eighty-seven Australian English-speaking preschoolers (aged 4-5 years) with PI completed the Children's Assessment of Morphophonology (CHAMP)-an elicited response task-in addition to standardised tests of speech and receptive language...

There is continuing debate about the origins of productive morphological errors in children with speech sound disorders. This is the case for children with theorised phonetic and motor disorders, such as children with childhood apraxia of speech (CAS, e.g., Ekelman & Aram, 1983; McNeill & Gillon, 2013 ). The morphological skills of children with CAS remain relatively unexplored in pre-schoolers. We investigated English morphology in a retrospective, cross-sectional design of 26 children aged 4-5 years who completed the Clinical Evaluation of Language Fundamentals-Preschool (2nd edition; Wiig, Secord & Semel, 2006)...

Speakers of North American English use variable tongue shapes for rhotic sounds. However, quantifying tongue shapes for rhotics can be challenging, and little is known about how tongue shape complexity corresponds to perceptual ratings of rhotic accuracy in children with residual speech sound errors (RSE). In this study, 16 children aged 9-16 with RSE and 14 children with typical speech (TS) development made multiple productions of 'Let Robby cross Church Street'. Midsagittal ultrasound images were collected once for children with TS and twice for children in the RSE group (once after 7 h of speech therapy, then again after another 7 h of therapy)...

Acoustic measurements have shown that the speech of hearing-impaired (HI) children differs from that of normally hearing (NH) children, even after several years of device use. This study focuses on the perception of HI speech in comparison to NH children's speech. The purpose of this study was to investigate whether adult listeners can identify the speech of NH and HI children. Moreover, it is studied whether listeners' experience and the children's length of device use play a role in that assessment. For this study, short utterances of 7 children with a cochlear implant (CI), 7 children with an acoustic hearing aid (HA) and 7 children with NH were presented to 90 listeners who were required to specify the hearing status of each speech sample...

The purpose of this paper is to provide guidelines on how to develop a naming test for an under-researched language, through adaptation of an English test. An additional consideration is how to make an assessment suitable for bilinguals. While test development involves a number of phases, the focus in this research is on test construction. To illustrate the steps required for this, a Tongan adaptation of the Boston Naming Test (BNT) for Tongan-English bilinguals is discussed. In the adaptation, language structure and cultural appropriateness are considered in item selection...

Identification of children with specific language impairment (SLI, now known as Developmental Language Disorder) remains challenging. Morphosyntax difficulties have been proposed as potential linguistic 'markers' for SLI across a number of languages. This study investigates the existence of such a clinical marker in German-speaking children with SLI, looking in particular at German case marking, and makes comparisons with matched typically developing groups and a group with isolated phonological impairment (PI)...

Cluttering is a fluency disorder which can be characterised by excessive disfluencies. However, the low number of studies dealing with the analysis of disfluencies in cluttering show contradictory results. The aim of this article is to analyse disfluency clusters in cluttered, fast and typical speech. Frequency of all disfluency clusters and those complex disfluencies which contain more than two constituents were analysed. The number and types of the constituents of complex disfluencies and the reason of their occurrence were analysed in detail...

Dysphonia Severity Index (DSI) is an objective multi-parametric measurement of voice quality, which has been widely used in different countries. Studies indicate that DSI may be influenced by vocal pathology, age and geographical factors, whereas gender does not significantly affect DSI. The purpose of this study was to investigate the effects of gender and age on the DSI and related parameters in a Shanghainese population. The present study measured the DSI and the parameters maximum phonation time (MPT), highest fundamental frequency (HF0), lowest intensity (LI) and Jitter in 187 Shanghainese subjects, including 106 young adults aged 18-23 years (52 males and 54 females) and 81 children aged 7-9 years (44 boys and 37 girls)...

The current study investigates the role of the morphophonological realisation of grammatical features as a compensatory mechanism for morphosyntactic deficits in specific language impairment (SLI). The phenomenon examined is past tense formation in Standard Modern Greek (SMG) and Cypriot Greek (CG) as it manifests a distinction in morphophonological salience realisation in the two linguistic varieties via differential use of a stress shift and stressed syllabic augment [é] required for past tense rule formation...

Analysing spoken and written language samples across different genres provides speech-language pathologists (SLPs) and educators with information about adolescents' production of complex syntax, an important socially and academically related language skill. However, researchers report that production of complex syntax is affected by genre and modality. Although the narrative and expository genres elicit a greater amount of complex syntax than conversational discourse, it is unknown whether differences in production of complex syntax exist between the persuasive and expository genres...

Non-word repetition is weaker for adults who stutter (AWS) compared to adults who do not stutter (AWNS) as phonological demands increase. However, non-word stimuli used in previous studies varied by length, but did not vary with regard to segmental or metrical complexity. The purpose of the present study was to examine the unique influence of these two distinct types of complexity on non-word repetition in AWS and AWNS via administration of the Test of Phonological Structure (TOPhS). Twenty-four adults (12 AWNS, 12 AWS) repeated 96 non-words within a soundproof booth immediately after auditory presentation...

This pilot study aims to evaluate the effectiveness of a school-based intervention using visual strategies for improving accurate use of auxiliary and copula marking in singular and plural, past and present tense by students with moderate learning disability and complex needs. Eleven students, aged 10-14 years, in a specialist school based in the UK, participated in the study. A within participants design was used which included testing at baseline, pre- and post-intervention to consider progress with intervention as compared with progress during a baseline period of similar length...
