A multimodal approach combining acoustics, intelligibility ratings, articulography and surface electromyography was used to examine the characteristics of dysarthria due to cerebral palsy (CP). CV syllables were studied by obtaining the slope of F2 transition during the diphthong, tongue-jaw kinematics during the release of the onset consonant,…

Language functions are generally represented in the left cerebral hemisphere. After early (prenatally acquired or perinatally acquired) left hemispheric brain damage language functions may be salvaged by reorganization into the right hemisphere. This is different from brain lesions acquired in adulthood which normally lead to aphasia. Right…

Some children with cerebral palsy have articulation disorders that are resistant to conventional speech therapy. The aim of this study was to investigate whether the visual feedback method of electropalatography (EPG) could be an effective tool for treating five children (mean age of 9.4 years) with dysarthria and cerebral palsy and to explore…

This paper analyses consonant articulation errors in dysarthric speech produced by seven American-English native speakers with cerebral palsy. Twenty-three consonant phonemes were transcribed with diacritics as necessary in order to represent non-phoneme misarticulations. Error frequencies were examined with respect to six variables: articulatory…

Inequality in communicative resources available to non-speaking children with cerebral palsy in comparison with their "naturally" speaking co-participants has material consequences for the ways in which face-to-face interaction is organized. Analyses of interaction involving non-speaking children with physical disability and speaking…

Familiarity is thought to aid listeners in decoding disordered speech; however, as the speech signal degrades, the "familiarity advantage" becomes less beneficial. Despite highly unintelligible speech sound production, many children with dysarthria vocalize when interacting with familiar caregivers. Perhaps listeners can understand these…

The primary objective of the present study was to document tone production and intelligibility deficits in Mandarin-speaking persons with cerebral palsy (CP). Spastic, athetoid, and mixed types of CP were studied, along with a control group, to investigate the possibility of tone production and intelligibility deficits that were differentially…

This study examined the relative benefit of three interventions (i.e. physiological, behavioural, and pragmatic) designed to facilitate speech recognition software use. Participants were 15 adults with dysarthria associated with a variety of aetiological conditions, including cerebral palsy, Parkinson's disease, and motor neuron disease. Results…

An analysis is presented of two different therapeutic activities designed for a profoundly deaf adult with cerebral palsy, DP. The study draws on techniques of qualitative methodology to identify elements that contribute to effective intervention practices for DP. Results indicate that therapeutic materials and activities must first of all be…
