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…

Purpose: This study examined acoustic predictors of speech intelligibility in speakers with several types of dysarthria secondary to different diseases and conducted classification analysis solely by acoustic measures according to 3 variables (disease, speech severity, and dysarthria type). Method: Speech recordings from 107 speakers with…

The study examined the possibility that children who omit word-final stops as a clinical entity may preserve the voicing contrast of those omitted stops by differential durations of the preceding vowel. (Author)

The primary objective of this position paper is to assess the theoretical and empirical support that exists for the Mayo Clinic view of motor speech disorders in general, and for oromotor, nonverbal tasks as a window to speech production processes in particular. Literature both in support of and against the Mayo clinic view and the associated use…

The paper reviews instrumental studies of "functional" misarticulations in children and reports an experiment involving three subject groups (N=7 in each group) of normally articulating adults, normally articulating children, and children who misarticulate the /s/ sound. (Author)

Acoustic data for 26 typically speaking 9 to 15 year olds for the /s/ frication were collected and evaluated. Analysis of the reference data set indicated that acoustic characterization of /s/ is appropriately and optimally obtained from the midpoint of /s/, represented in linear scale, referenced to individual linguistic-phonetic contexts,…

Purpose: This study was designed to determine whether within-speaker fluctuations in speech intelligibility occurred among speakers with dysarthria who produced a reading passage, and, if they did, whether selected linguistic and acoustic variables predicted the variations in speech intelligibility. Method: Participants with dysarthria included a…
