This article reviews conventions for transcribing suprasegmental features in spoken English. It proposes that symbols based on the International Phonetic Alphabet and its recent extensions be supplemented, in the area of intonation, by selected tonetic stress marks and examples of the autosegmental notation used in the Tone and Break Indices…

This article reviews major approaches to the transcription of disordered speech using the International Alphabet (IPA). Application of selected symbols for transcribing non-English sounds is highlighted in clinical examples, as are commonly used diacritic symbols. Included is an overview of the IPA extensions for transcription of atypical speech,…

Images of tongue/palate contact for the nasal phoneme /n/ were created using the electropalatograph (EPG). Seven typical Australian adults with no history of hearing or communication difficulty produced syllables containing /n/ paired with five vowels. The majority of productions were symmetrical had contact with the alveolar ridge, and lateral…

Children with developmental speech disorders may have additional deficits in speech perception and/or short-term memory. To determine whether these are only transient developmental delays that can accompany the disorder in childhood or persist as part of the speech disorder, adults with a persistent familial speech disorder were tested on speech…

This study investigated lower-lip motor processes underlying production of iambic and trochaic metrical forms with 16 children (ages 3 and 4) and eight adults. Movement patterns were well differentiated for both groups but in qualitatively different ways. Results suggest that metrical forms are perceptually and linguistically established.…

Short-term changes in vowel fundamental frequency immediately preceding and following voiceless obstruents were examined in 30 4-year-olds, 8-year-olds, and 21-year-olds. Results suggest that fundamental frequency offset is simply an acoustic consequence of producing a voiceless obstruent preceded by a vowel since there were minimal age-related…

This article discusses 4 types of phonological knowledge: knowledge of the acoustic and perceptual characteristics of speech sounds (perceptual knowledge), knowledge of the articulatory characteristics of speech sounds (articulatory knowledge), higher level knowledge of the ways that words can be divided into sounds and related phonotactic…

This volume examines the ramifications of individual differences in therapy outcomes for a wide variety of communication disorders. In an era where evidence-based practice is the clinical profession's watchword, each chapter attacks this highly relevant issue from a somewhat different perspective. In some areas of communication disorders,…

This study examined visual analog scaling judgments of disfluency by normal listeners in response to oral reading by 20 adults with spasmodic dysphonia (SD) and nondysphonic controls. Findings suggest that although dysfluency is not a defining feature of SD, it does contribute significantly to the overall clinical impression of severity of the…

This paper examines a prolonged speech treatment model for stuttering, the Camperdown Program. Sixteen participants showed minimal or no stuttering in everyday speaking situations for up to 12 months after entering the program's maintenance phase, with speech rates in the normal range. Results were achieved in a mean of 20 hours of clinic…

This study (with 16 children and 11 adults) examined an alternative to the Developmental Weighting Shift model which explains age-related differences in labeling of speech stimuli as due to increasing experience with word-internal structure. Findings rejected the alternative model, that changes in perceptual weighting strategies are due to…

The anatomy of speech and language-related cortical areas is reviewed with an emphasis on neuroimaging methods that have been utilized to better understand the anatomy and functional extent of critical speech-language areas. Contributions from pneumoencephalography, computerized tomography scans, and magnetic resonance imaging are discussed.…

This review discusses how general principles of brain development have contributed to both human brain plasticity and the acquisition of the human capacity for speech. Specifically, the role played by plastic developmental processes in the evolution and development of articulate control over vocalization in speech is examined. (Contains…

This article reviews literature relating to the role of severe congenital speech impairment on phonological processing before reporting on a study of five adults with severe congenital speech impairments and their responses on tasks involving reading, receptive vocabulary, lexical decision making, and phoneme identification. Difficulties with…

Telephone interviews with families (n=4,689) in New South Wales, Australia, found the prevalence of stuttering in the overall population was 0.72% with highest rates in children (1.4) and lowest in adolescents (0.53%). Male to female ratios were 2.3:1 overall. Incidence estimates ranged from 2.1% in adults to 3.4% in older children. The…
