The use of novel stimuli for obtaining nasalance measures in young children was the focus of this study. The subjects were 20 children without a history of communication disorders and 20 children at risk for velopharyngeal insufficiency (VPI). Each subject recited three passages; the standard Zoo Passage, and two novel stimuli that were named the Turtle(More)
The effects of vocal loudness on measures of nasalance was evaluated. Subjects were 30 young adult females with no history of communication disorder who spoke two stimulus passages at three levels of vocal loudness. One passage contained no nasal consonants (Zoo Passage) and the other contained about 35% nasal consonants (Nasal Sentences). The results(More)
The purpose of this study was to take a critical look at a voice therapy technique known as the yawn-sigh. The voiced sigh as an approach in voice therapy has had increased use in recent years, particularly with problems of vocal hyperfunction. In this study, the physiology of the yawn-sigh was studied with video nasoendoscopy in eight normal subjects;(More)
This study correlated measures of nasalance computed by the Nasometer with listener judgments of nasality. The subjects were 25 children with craniofacial disorders who spoke three passages, each containing a different proportion of nasal consonants. The results showed a significant but modest correlation between nasalance and nasality when nasal consonants(More)
Neural response time (NRT) was compared for 12 adult stutterers and 12 matched normal speakers on two verbal tasks (production of /pae/ and /bae/) and one oral, nonverbal task (lip closure) in response to visual and auditory stimulation. The auditory response stimulus was presented separately to the left and right ears, and the visual stimulus to both eyes.(More)
The purpose of this study was to determine whether stutters and nonstutterers differed in latency of vocalization onset as a function of auditory and visual stimulus presentations. Twelve adult stutterers and 12 adult nonstutterers were compared for phonation onset latency under conditions of visual, right ear auditory, and left ear auditory cueing.(More)
This study compared the vibratory characteristics of normal vocal folds, Teflon-injected paralyzed vocal folds, and noninjected paralyzed vocal folds. Laryngeal videostroboscopy under eight phonatory conditions showed that the Teflon-injected vocal folds were adynamic. The noninjected vocal folds, however, vibrated during each of the phonatory conditions(More)
