Phonatory Symptoms and Acoustic Findings in Patients with Asthma: A Cross‐Sectional Controlled Study

Subjects and Methods: A total of 50 subjects, 31 asthmatics and 19 control subjects matched according to age and gender were enrolled in this study. All subjects were asked about the presence or absence of cough, dyspnea, respiratory failure, dysphonia, degree of vocal fatigue and phonatory effort. Perceptual evaluation, acoustic analysis and aerodynamic measurements were also performed. Patient’s self assessment using the Voice Handicap Index 10 was reported.
