“…4 On a larger scale, voice has also been considered an acoustic cue to body size and shape. 5,6 There is invariably an inverse relationship among body weight, height, and vocal pitch. 7 More so, there is a correlation among vocal pitch, shoulder and waist-to-hip ratio, and skull and chest circumference.…”

“…People with obesity have an altered voice quality, which is perceived as more strangled, hoarse, and breathy compared with nonobese ones [16]. Another study with class III subjects reported hoarseness, murmuring, vocal instability, altered jitter and shimmer, voice strangulation at the end of emission, and decreased MPT [12].…”

“…On the other hand, there are reports showing that there is no change in the MPT in people with obesity after the surgery [16,17]. In one of these studies, although one-third of patients showed a change in the voice quality after weight loss, it was not detected acoustically, and the MPTdid not change [16]. In addition, most of the patients were not class III obese according to the World Health Organization classification [21].…”

“…ere is a controversy about what happens to the MPT after surgical treatment of obesity and consequent weight loss. While some studies have shown increased MPT after surgery [11,15], others have shown no alteration [16,17]. Our hypothesis was that (a) obesity decreases MPT, which is improved after surgical treatment of obesity; (b) there is a correlation of the duration of MPT with weight, body mass index (BMI), and neck circumference; and (c) obesity causes abnormalities in forced expiratory volume in one second (FEV 1 ) and forced vital capacity (FVC).…”

Maximum Phonation Time in People with Obesity Not Submitted or Submitted to Bariatric Surgery

2019

Background. Our aim in this investigation was to evaluate maximum phonation time in people with obesity not submitted to surgery and in people with obesity submitted to bariatric surgery and compare it with maximum phonation time of healthy volunteers. The hypothesis was that the reduced maximum phonation time in people with obesity would be corrected after surgery due to weight loss. Method. Maximum phonation time was evaluated in 52 class III patients (Group A), 62 class III patients who were treated by surgery 3 to 115 months before (Group B), 20 controls (Group C), and 15 class III patients whose maximum phonation time was evaluated before and two to six months after surgery (Group D). Maximum phonation time was measured in the sitting position with the vowels /A/, /I/, and /U/. Results. Maximal phonation time was shorter in groups A and B compared with that of controls. There was an increase in maximal phonation time after surgery (Group B); however, the difference was not significant when compared with that in group A. In group D, maximal phonation time for /A/ increased after the surgery. In group A, there was a negative correlation between maximal phonation time and weight or body mass index and a positive correlation between maximal phonation time and height. In group B, there was an almost significant positive relation between percentage of weight loss and maximal phonation time for /A/ (p=0.08) and /I/ (p=0.07). Mean values of spirometry testing (FEV1, FVC, and FEV1/FVC) in people with obesity (groups A and B), expressed as percentage of the predicted value, were within the normal range. Conclusion. Compared with healthy controls, maximal phonation time is shorter in people with obesity, with a tendency to increase after bariatric surgery, as a possible consequence of weight loss.

“…Biological patterns of voice production associated with physical body characteristics are not new concerns in the field of voice quality research; however, the results achieved are controversial and none of these studies included dysphonic speakers. 6,[10][11][12][13][14][15][16][17][18][19][20][21] Body size has been related to vocal tract morphology. [10][11][12][13][14]16 Fitch and Giedd 10 found differences in vocal tract morphology both in male and in female speakers, including changes in vocal tract length and in the relative proportions of the oral and the pharyngeal cavities, with consequences in formant frequencies.…”
