Magnetic resonance imaging (MRI) techniques were used to gather basic data to apply in computational models of speech articulation. Two experiments were performed. In experiment 1, voice recordings from two male subjects were obtained simultaneously with axial, coronal, or midsagittal MR images of their vocal tracts while they produced the four point(More)
We evaluated 4 patients who developed severe, symptomatic stridor during maximal cardiopulmonary exercise testing, all referred due to exercise-related dyspnea. All underwent resting, unsedated transnasal fiberoptic laryngoscopy and had normal findings. Four patients performed repeat maximal exercise testing with fiberoptic laryngoscopy, and they form the(More)
The speech of individuals with Parkinson's Disease (PD) is characterized by reduced stress, increased rate, monotonic pitch and loudness and imprecise consonant production (see Darley, Aronson, & Brown, 1975 for review). Acoustically, speech has decreased duration of voiced segments, reduced fundamental frequency variations and limited formant trajectories(More)
Magnetic resonance imaging (MRI) is a useful modality for three-dimensional evaluation of laryngeal anatomy. The authors present data on patients with unilateral vocal fold paralysis both before and after type I thyroplasty for medialization. Videoendoscopic and acoustic measures were obtained. MRI was performed preoperatively and postoperatively.(More)
Thevoiced/voiceless distinction for English utterance-initial stop consonants is primarily realIzed as differences in the voice onset time (VOT), which is largely signalled by the time between the stop burst and the onset of voicing. The voicing of stops has also been shown to affect the vowel's FO after release, with voiceless stops being associated with(More)
