Primary progressive aphasia (PPA) is an acquired neurodegenerative syndrome that has specific and devastating effects on an individual's speech and language ability. Based on a detailed assessment of behavior and cognition, combined with structural neuroimaging data and pathological evidence, PPA is typically classified into three variants: the…

This article analysed the acoustic structure of voiced stop ++ vowel sequences in a group of persons who stutter (PWS). This phonetic unit was chosen because successful production is highly dependent on the differential tweaking of right-to-left anticipatory coarticulation as a function of stop place. Thus, essential elements of both speech motor…

This article documents the typological occurrence and interactions of two seemingly independent error patterns, namely Velar Fronting and Labial Harmony, in a cross-sectional investigation of the sound systems of 235 children with phonological delays (ages 3;0 to 7;9). The results revealed that the occurrence of Labial Harmony depends on the…

This study describes the realization of onset and coda clusters in a 4-year old child acquiring American English, and with a higher than usual level of unintelligible speech. It reviews previous studies that have tested cluster realization against markedness and, in particular, the sonority hypothesis. This latter predicts steep rises in sonority…

This study investigated the development of English two-member onset #sC clusters in Spanish-English bilingual children with phonological disorders. Data from 30 children were analysed in terms of correct and incorrect productions, implicational relationships, and possible groupings according to the sonority index of the second member of the…

This study examines the production and reduction patterns of initial /s/ clusters by Hebrew-speaking children with phonological disorders. Data were collected from 30 children with phonological disorders between the ages of 3;5-5;2. The data were elicited by means of a picture-naming task combined with a sentence completion task. Target words…

Well-documented Romance-Germanic differences in the use of accent in speech to convey information-structure and focus cause problems for the assessment of prosodic skills in populations with clinical disorders. The strategies for assessing the ability to use lexical and contrastive accent in English and Spanish are reviewed, and studies in the…

Phonological acquisition traditionally has been measured using constructs that focus on segments rather than the whole words. Findings from recent research have suggested whole-word productions be evaluated using measures such as phonological mean length of utterance (pMLU) and the proportion of whole-word proximity (PWP). These measures have been…

The purpose of this paper was to examine the psychometric properties of a non-word repetition task (NRT), the Late-8 Non-word Repetition Task (L8NRT). This task was designed similarly to the NRT, but contains only Late-8 consonants to increase articulatory demands and avoid ceiling effects in studies with adolescents and adults. Thirty college…

This article honours Adele Miccio's life work by reflecting on the utility of phonetic transcription. The first section reviews the literature on cases where children whose speech appears to neutralize a contrast in the adult language are found on closer examination to produce a contrast ("covert contrast"). This study presents evidence…

Two member onset consonant clusters with /s/ as the first member (#sC onsets) behave differently from other double onset consonant clusters in English. Phonological explanations of children's consonant cluster production have been posited to predict children's speech acquisition. The aim of this study was to consider the role of the Sonority…

The purpose of the current study is to document phonological change from a multidimensional perspective for a 3-year-old boy with phonological disorder by comparing three measures: (1) accuracy of consonant productions, (2) dynamic assessment, and (3) acoustic analysis. The methods included collecting a sample of the targets /s, [image omitted],…

Generalization refers to the extension of learned behaviours to novel conditions, and it is one of the criteria by which the effectiveness and efficiency of a remediation programme may be judged. This article extracts principles of generalization from the treatment literature, and provides examples of how this information may be used to help guide…

Discusses the problems in obtaining data for the error analysis of deviant speech. It is suggested that the only way to obtain reliable data is to compare the difference between utterances of handicapped subjects and the analyzer's expectations with the differences of non-handicapped subjects and the analyzer's expectations.

The authors studied the acquisition of nine #sC clusters in 30 Croatian-speaking phonologically disordered children, aged between 3;8-7;0 years, by analysing their renditions of target words elicited in response to visual stimuli presented on a computer screen. Results did not support the idea that a greater jump in sonority from C1 to C2 would…
