Treatment using electropalatography (EPG) is described. Speech learners wear a custom-made appliance called a pseudopalate in order to view their tongue-to-palate (lingual palatal) contacts on a computer monitor. The results from studies with children who have either articulation or phonology-based problems are discussed. Assessments of contact patterns(More)
Five profoundly hearing-impaired children were taught the consonants /t,d,k,g,s,z integral of/ using palatometry. Changes in linguapalatal contact patterns and listener perceptions showed significant improvement in the place and manner of consonants produced by all subjects. Velar stops were as easily and accurately learned as alveolar stops. Distinctive(More)
This study examined changes in the sentence intelligibility scores of speakers with dysarthria in association with different signal-independent factors (contextual influences). This investigation focused on the presence or absence of iconic gestures while speaking sentences with low or high semantic predictiveness. The speakers were 4 individuals with(More)
Ten normal hearing (NH) and 18 profoundly hearing-impaired (HI) children were recorded using palatometry and audiotape while producing the consonants /t,d,k,g,s,z,integral of/ in CV syllables (V = /i, a/). The lingual-palatal contacts produced by the NH subjects for the alveolar stops were undifferentiated across voicing and vowel environment differences.(More)
The effects of noise and reverberation on the identification of monophthongs and diphthongs were evaluated for ten subjects with moderate sensorineural hearing losses. Stimuli were 15 English vowels spoken in a /b-t/ context, in a carrier sentence. The original tape was recorded without reverberation, in a quiet condition. This test tape was degraded either(More)
There were two aims of this study. The first was to compare indirect inferencing abilities by nine right hemisphere brain-damaged (RHD) adults with 18 matched normal controls. The second purpose was to determine the best condition in which to present information to the RHD individuals for the purpose of forming these inferences. Three conditions were(More)
This study investigated the effects of listening condition on speech rate judgment. Four listening conditions, in which a single sentence was presented at 21 speech rates ranging from 90 WPM to 250 WPM, were incorporated. These conditions included non-degraded, reverberation, band-pass filtered, and low-pass filtered conditions, each of which was selected(More)
Sentences recorded by four speakers with dysarthria and two control speakers were presented to listeners at three different rates: habitual, a 30% slower rate and a 30% higher rate. Rate changes were made by digitally manipulating the habitual sentences. Thirty young normal adult listeners rated the sentences for intelligibility (per cent correct words) and(More)
PURPOSE This study attempted to determine whether there were any differences or similarities in the basic cognitive and language skills of 4 groups of adolescents: adjudicated (a judge's decision to establish responsibility for a delinquent act) and nonadjudicated male and females. METHOD The 4 groups of adolescents were 18 adjudicated females, 18(More)
Two groups of nine children with profound hearing impairments and low intelligibility were taught to produce the consonants /t,d,k,g,s,z,S/ using either electropalatographic (palatometry) or traditional aural-oral techniques. Testing was completed pre-, immediately post-, and 6 months post-treatment by examining productions of CV syllables (V = /i,a/) using(More)
