Background Dutch is a West‐Germanic language spoken natively by around 24 million speakers. Although studies on typical Dutch speech sound development have been conducted, norms for phonetic and phonological characteristics of typical development in a large sample with a sufficient age range are lacking. Aim To give a detailed description of the speech sound development of typically developing Dutch‐speaking children from 2 to 7 years. Methods & Procedures A total of 1503 typically developing children evenly distributed across the age range of 2;0–6;11 years participated in this normative cross‐sectional study. The picture‐naming task of the Computer Articulation Instrument (CAI) was used to collect speech samples. Speech development was described in terms of (1) percentage consonants correct—revised (PCC‐R) and percentage vowels correct (PVC); (2) consonant, vowel and syllabic structure inventories; (3) degrees of complexity (phonemic feature hierarchy); and (4) phonological processes. Outcomes & Results A two‐way mixed analysis of variance (ANOVA) confirmed a significant increase in the number of PCC‐R and PVC between the ages of 2;0 and 6;11 years (p < 0.001). The consonant inventory was found to be complete at 3;7 years of age for the syllable‐initial consonants, with the exception of the voiced fricatives /v/ and /z/, and the liquid /r/. All syllable‐final consonants were acquired before age 4;4 years. At age 3;4 years, all children had acquired a complete vowel inventory, and at age 4;7 years they produced most syllable structures correctly, albeit that the syllable structure CCVCC was still developing. All phonological contrasts were produced correctly at 3;8 years of age. Children in the younger age groups used more phonological simplification processes than the older children, and by age 4;4 years, all had disappeared, except for the initial cluster reduction from three to two consonants and the final cluster reduction from two to one consonant. Conclusions & Implications This paper describes a large normative cross‐sectional study of Dutch speech sound development which, in clinical practice, can help Dutch speech–language pathologists to differentiate children with delayed or disordered speech development from typically developing children.

Speech sound development of young Dutch children with a developmental language disorder: A complex matter

BackgroundApproximately 50% of all young children with a developmental language disorder (DLD) also have problems with speech production. Research on speech sound development and clinical diagnostics of speech production difficulties focuses mostly on accuracy; it relates children's phonological realizations to adult models. Contrarily to these relational analyses, independent analyses indicate the sounds and structures children produce irrespective of accuracy. Such analyses are likely to provide more insight into a child's phonological strengths and limitations, and may thus provide better leads for treatment.AimsRam (1) To contribute to a more comprehensive overview of the speech sound development of young Dutch children with DLD by including independent and relational analyses, (2) to develop an independent measure to assess these children's speech production capacities; and (3) to examine the relation between independent and relational speech production measures for children with DLD.Methods & ProceduresWe describe the syllable structures and sounds of words elicited in two picture‐naming tasks of 82 children with DLD and speech production difficulties between ages 2;7 and 6;8. The children were divided into four age groups to examine developmental patterns in a cross‐sectional manner. Overviews of the children's productions on both independent and relational measures are provided. We conducted a Spearman correlation analysis to examine the relation between accuracy and independent measures.Outcomes & ResultsThe overviews show these children are able to produce a greater variety of syllable structures and consonants irrespective of target positions than they can produce correctly in targets. This is especially true for children below the age of 4;5. The data indicate that children with DLD have difficulty with the production of clusters, fricatives, liquids and the velar nasal (/ŋ/). Based on existing literature and our results, we designed a Dutch version of an independent measure of word complexity, originally designed for English (word complexity measure—WCM) in which word productions receive points for specific word, syllable and sound characteristics, irrespective of accuracy. We found a strong positive correlation between accuracy scores and scores on this independent measure.Conclusions & ImplicationsThe results indicate that the use of independent measures, including the proposed WCM, complement traditional relational measures by indicating which sounds and syllable structures a child can produce (irrespective of correctness). Therefore, the proposed measure can be used to monitor the speech sound development of children with DLD and to better identify treatment goals, in combination with existing relational measures.WHAT THIS PAPER ADDSWhat is already known on the subjectSpeech production skills can be assessed in different ways: (1) using analyses indicating the structures and sounds a child produces irrespective of accuracy, that is, performance analyses; and (2) using analyses indicating how the productions of a child relate to the adult targets, that is, accuracy analyses. In scientific research as well as in clinical practice the focus is most often on accuracy analyses. As a consequence, we do not know if children who do not improve in accuracy scores, improve in other phonological aspects that are not captured in these analyses, but can be captured by performance analyses.What this study adds to the existing knowledgeThe overviews show these children are able to produce a greater variety of syllable structures and consonants irrespective of target positions than they can produce correctly in targets. Consequently, adding performance analyses to existing accuracy analyses provides a more complete picture of a child's speech sound development.What are the potential or actual clinical implications of this work?We propose a Dutch version of a WCM, originally designed for English, in which word productions receive points for word structures, syllable structures and sounds, irrespective of accuracy. This measure may be used by Dutch clinicians to monitor the speech sound development of children with DLD and to formulate better treatment goals, in addition to accuracy measures that are already used.

Children steer the inflectional diversity of their parents: The role of word births and growing vocabulary

The inflectional diversity of parents’ speech directed to children acquiring Dutch was investigated. Inflectional diversity is defined as the number of inflected forms of a particular lemma (e.g. singular, plural of a noun) and measured by means of Mean Size of Paradigm (MSP). Changes in the inflectional diversity of infant directed speech (IDS) were analyzed as a function of children’s developing linguistic abilities. Two types of changes in the inflectional diversity of nouns and verbs were analyzed: (1) coarse tuning: changes relative to children’s growing vocabulary and (2) fine lexical tuning: changes relative to children’s use of specific lexical items. In addition, it was investigated if those changes were similar depending on particular characteristics of the children, namely, differences in their hearing abilities. Longitudinal recordings of spontaneous speech of 30 children (0;6-2;0) with normal hearing (NH) and 10 hearing-impaired children with a cochlear implant (CI) (0;6-2;6), and their parents were analyzed. As to coarse tuning, it was found that the inflectional diversity of IDS decreased at the beginning of the child’s lexical development but increased again parallel to infants’ growing cumulative vocabulary. As to fine lexical tuning, IDS showed less inflectional diversity before each child’s first use of a word and gradually more inflectional diversity afterward. In addition, parents of children with CI used less inflectionally diverse speech than parents of children with NH, which suggests an adaptation to specific characteristics of the children. In conclusion, inflectional morphology in IDS appears to be tuned to children’s hearing status and linguistic knowledge.
