This paper investigates various aspects of intonation and phonation in young adults with Down syndrome. The speech of nine speakers with Down syndrome was analyzed acoustically for different aspects of intonation and phonation. The results of these analyses were compared to similar speech samples of nine typical speakers of Standard British English. The controls were matched for age and gender....

The correlation between laryngo-pharyngeal reflux and dysphonia has been evaluated in patients without significant laryngoscopic findings and without vocal misuse. Studies were performed, using a validated questionnaire on typical reflux symptoms as well as instrumental means, e.g. videolaryngoscopy, multi-electrode 24-hr oesophageal pH monitoring, vocal acoustic analysis, gastro-oesophagoscopy...

BACKGROUND The objective of this work was to obtain a controlled subjective and objective in vivo clinical comparison of the Passy-Muir, Shiley, and Ball speaking valves. METHODS Ten patients free of laryngeal pathology but dependent on tracheotomy for respiration were tested with each of the speaking valves. Olfaction was assessed for each patient using the University of Pennsylvania Smell I...

ABSTRACT Purpose: to characterize voice therapy with a respiratory approach in dysphonic older people. Methods: search made PubMed, VHL, Scopus, Web of Science, and EMBASE. Original studies English, Spanish, Portuguese, addressing combination the population, were included. The analysis encompassed sex, age, associated etiology, session frequency duration, exercise dosage, intervention, benefits...

Background and aims: Maximum phonation time (MPT), which is related to respiratory function, is widely used to evaluate maximum vocal capabilities, because its use is non-invasive, quick, and inexpensive. We aimed to examine differences in MPT by age, following recovery phase II cardiac rehabilitation (CR). Methods: This longitudinal observational study assessed 50 consecutive cardiac patients ...

BACKGROUND Obese people have abnormal deposition of fat in the vocal tract that can interfere with the acoustic voice. Aim : To relate the fundamental frequency, the maximum phonation time and voice complaints from a group of morbidly obese women. METHODS Observational, cross-sectional and descriptive study that included 44 morbidly obese women, mean age of 42.45 (± 10.31) years old, observat...

This paper analyzes the interaction between the vocal folds and vocal tract at phonation onset due to the acoustical coupling between both systems. Data collected from a mechanical replica of the vocal folds show that changes in vocal tract length induce fluctuations in the oscillation threshold values of both subglottal pressure and frequency. Frequency jumps and maxima of the threshold pressu...

BACKGROUND Maximum phonation times (MPT) of vowels in adult women with vocal nodules. AIM To verify and to correlate the values of MPT of vowels in young and middle-aged adult women with vocal nodules. METHOD Database records from a speech therapy school-clinic were used, making up a total of 38 subjects. INCLUSION CRITERIA female adults, aged between 20 and 53 years, with otorhinolaryngo...
