Vowel inventories and error patterns for three children with suspected developmental apraxia of speech (DAS) were analysed over a 3-year period using phonetic transcriptions of connected speech samples. The children demonstrated complete English vowel inventories except for rhotics. However, accuracy of vowel targets in connected speech did not…

Error inconsistency is often cited as a characteristic of children with speech disorders, particularly developmental apraxia of speech (DAS); however, few researchers operationally define error inconsistency and the definitions that do exist are not standardized across studies. This study proposes three formulas for measuring various aspects of…

Impaired speech prosody has been identified as a critical feature of suspected childhood apraxia of speech (sCAS). Lexical stress productions of children with sCAS have been characterized as 'excessive/equal/misplaced'. This investigation examines two potential explanations of this particular deficit, articulatory difficulty and impaired intrinsic…

Although there is extensive documentation of the morphological limitations of children with specific language impairment (SLI), few studies have reported on complex syntax acquisition in children with SLI. This case study examined the development of complex syntax in a child with SLI between 3 and 7 years. Twelve conversational samples were…

This study examined ten children with specific language impairment (SLI), 16 normally developing children, and ten adults for the production of novel root compounds. The participants were asked to invent names for pictures of 24 pairs of contrasting, novel objects. For half of the pictures, the context supported a grammatical novel root compound,…
