Background: Accurate nonword repetition (NWR) is contingent on many underlying skills, including encoding, memory and motor planning and programming. Though vowel errors are frequently associated with childhood apraxia of speech (CAS), several recent studies have found that children with developmental language disorder (DLD) produce high rates of…

Some children's speech impairment resolves spontaneously. Others have persistent problems affecting academic and social development. Identifying early markers that reliably predict long-term outcome would allow better prioritization for preschool intervention. This article evaluates the significance of different types of speech errors, made by 93…

We studied spontaneous speech noun-phrase production in eight French-speaking children with SLI (aged 5;0 to 5; 1) and controls matched on age (4;10 to 5;11) or MLU (aged 3;2 to 4;1). Results showed that children with SLI prefer simple DP structures to complex ones while producing more substitution and omission errors than controls. The three…

In this article we report two studies: a detailed longitudinal analysis of errors in "wh"-questions from six German-learning children (age 2 ; 0-3 ; 0) and an analysis of the prosodic characteristics of "wh"-questions in German child-directed speech. The results of the first study demonstrate that German-learning children…

Error patterns in children's phonological development are often described as simplifying processes that can interact with one another with different consequences. Some interactions limit the applicability of an error pattern, and others extend it to more words. Theories predict that error patterns interact to their full potential. While specific…

This dissertation investigates the acquisition of early verb inflection in child Slovenian from morphosyntactic and morphophonological perspectives. It centers on the phenomenon of root nonfinites, particularly the patterns of omission and substitution errors in verb inflection marking. It argues that every acquisition model needs to account…

Our previous research showed that Russian children commit fewer gender-agreement errors with diminutive nouns than with their simplex counterparts. Experiment 1 replicates this finding with Russian children (N=24, mean 3;7, range 2;10-4;6). Gender agreement was recorded from adjective usage as children described animal pictures given just their…

The acquisition of noun gender on articles was studied in a sample of 21 young German-speaking children. Longitudinal spontaneous speech data were used. Data analysis is based on 22 two-hourly speech samples per child from 6 children between 1 ; 4 and 3 ; 8 and on 5 two-hourly speech samples per child from 15 children between 1 ; 4 and 2 ; 10. The…

Two common and seemingly independent error patterns, namely consonant harmony and gliding, are examined for their typological characteristics based on cross-sectional and longitudinal evidence from young children's developing phonologies. Data are drawn from the published literature and from the developmental phonology archives at Indiana…

To examine possible explanations of reported inaccuracies of children with specific language impairment (SLI) on nonword repetition, study compared repetitions of 54 SLI children and peers for number and type of error, latency, and duration of response. Found no evidence of differences between groups in auditory discrimination or response…

In a study of very young children's pronunciation of nouns and verbs, ten children aged 20 to 25 months were exposed to experimental nouns and verbs, which had not yet been comprehended or produced by the children. Each of the objects and actions was given an experimental name based on phonemes in the children's speech. These objects and actions…

It is argued here that childhood phonological errors systematically simplify the child's inventory of phonetic elements and strings. (Author/KM)

Results of a study of sound system acquisition of five-year-old students of English-as-a-second-language show that first- and second-language learners exhibit similar but not identical simplification processes, and that evidence for a common developmental sequence in acquisition of consonant sounds was limited.

This project began with a theory about the prediction of errors in childrens' attempts to pronounce utterances modeled for them by adults. Subjects were children from 15 to 54 months old in all positions in the family. The sample from each child was an unprompted utterance judged to be an attempt to say something in English. Differences between…

Describes the phoneme repertoires and phonological error patterns used by Cantonese-speaking children, as well as a longitudinal study of tone acquisition by four children. The developmental error patterns used by more than 10% of children are reported as common in other languages. Specific rules associated with Cantonese phonology are identified.…
