Clinical measures of speech intelligibility are widely used as one means of characterizing the speech of individuals with dysarthria. Many variables associated with both the speaker and the listener contribute to what is actually measured as intelligibility. The present study explored the effects of presentation modality (audiovisual vs. audio-only(More)
PURPOSE This study examined the relationship between listener comprehension and intelligibility scores for speakers with mild, moderate, severe, and profound dysarthria. Relationships were examined across all speakers and their listeners when severity effects were statistically controlled, within severity groups, and within individual speakers with(More)
A growing body of experimental research suggests that speech supplementation strategies can markedly increase speech intelligibility for individuals with dysarthria (D. Beukelman & K. Yorkston, 1977; E. Crow & P. Enderby, 1989; L. Hunter, T. Pring, & S. Martin, 1991; K. C. Hustad & D. R. Beukelman, 2001). However, studies in which speech supplementation(More)
This study examined the effects of supplemental cues on the intelligibility of unrelated sentences and related sentences (narratives) produced by 4 women with severe dysarthria secondary to cerebral palsy. Visual images containing alphabet, topic, combined (alphabet and topic together), and no cues were imposed in real time on audio speech samples and(More)
PURPOSE This study addressed the effects of 3 different paradigms for scoring orthographic transcriptions of dysarthric speech on intelligibility scores. The study also examined whether there were differences in transcription accuracy among words from different linguistic classes. METHOD Speech samples were collected from 12 speakers with dysarthria of(More)
This study examined word level intelligibility differences between DECTalk and MacinTalk speech synthesizers using the Modified Rhyme Test in an open format transcription task. Three groups of listeners participated: inexperienced, speech-language pathologists, and speech synthesis experts. Results for between-subjects ANOVA showed that the expert group(More)
native communication (AAC) systems employ natural speech as one of several modes of communication. In spite of reduced intelligibility, these individuals are often able to communicate successfully using speech in specific situations with certain communication partners. For those AAC users who are able to produce natural speech, it is sometimes the most(More)
PURPOSE Speech acoustic characteristics of children with cerebral palsy (CP) were examined with a multiple speech subsystems approach; speech intelligibility was evaluated using a prediction model in which acoustic measures were selected to represent three speech subsystems. METHOD Nine acoustic variables reflecting different subsystems, and speech(More)
PURPOSE: The goals of this study were to 1) describe the feeding skills of young children with cerebral palsy (CP); and 2) elucidate the type and severity of feeding problems for children with and without oral-motor involvement. METHOD: Parents of 37 children (16 females, 21 males) with CP, who ranged in age from 11-58 months (mean age = 41 months),(More)
PURPOSE In this study, the authors proposed and tested a preliminary speech and language classification system for children with cerebral palsy. METHOD Speech and language assessment data were collected in a laboratory setting from 34 children with cerebral palsy (CP; 18 male, 16 female) with a mean age of 54 months (SD = 1.8). Measures of interest were(More)
