An aerodynamic investigation of the occurrence of intrusive stop consonants occurring in nasal-fricative consonant clusters in English revealed that intrusive stops were cued perceptually by silent gaps often followed by burst releases preceding the fricative consonant. In articulatory-aerodynamic terms, intrusive stops appear to result from a prolonged(More)
The speech of a five-year-old boy who suffered a profound hearing loss following meningitis was sampled at two-week intervals for nine months. Speech samples were subjected to phonetic transcription, spectrographic analysis, and intelligibility testing. Immediately post-trauma, the child displayed slightly slower, F0 elevated, acoustically intense speech in(More)
In this study, 22 children, ages 6:0 to 6:11, who misarticulated word-initial [r] as [w], were compared to 13, age-matched normally articulating children for their ability to identify and discriminate seven synthetic stimuli representing an acoustic continuum between [we] and [re]. Discrimination was tested among 3-step continuum stimulus pairs using the(More)
The imitation and recognition ability of brain-damaged and normal subjects was tested for 30 pairs of semantically matched ASL signs and corresponding Amer-Ind gestures. Subjects were rated according to severity and site of lesion. They were 6 nonaphasic, right-hemisphere brain-damaged subjects, 12 aphasic subjects, and 12 non-brain-damaged geriatric(More)
