“…Medial stable 10 seconds of sustained vowel samples of /a/, to avoid fade-in and fade-out effects of signal, were taken for acoustical analysis in Multidimensional Voice Profile (MDVP) and z-tool for measuring parameters such as the following: average F0: the average mean of vocal fold vibration across the length of the recorded voice sample of an individual; jitter and shimmer: the fluctuation rate or vocal fold vibratory characteristics in terms of frequency and intensity [ 21 ]; noise to harmonic ratio (NHR): the information on presence of noise in a particular voice signal compared to harmonic organization [ 22 , 23 ]; soft phonation index (SPI): a parameter to check for noise or breathiness in the voice signal; high rate of SPI indicates poor adduction of vocal folds and more breathy voice [ 23 ]; cepstral peak prominence and smoothened cepstral peak prominence (CPP and sCPP): the information on harmonic structure in the voice signal; they are the best predictors of dysphonic components of voice compared to NHR or SPI [ 16 , 24 , 25 ]. …”

Summary. Objective Pranayama is known for improving various health conditions. The present study is aimed at investigating the effects of bhramari pranayama on aerodynamic and acoustic parameters of voice in healthy individuals. Study Design This is a pretest-posttest design study. Methods A total of 24 participants in the age range of 20 to 25 years completed the bhramari pranayama regimen for 30 sessions. Aerodynamic and acoustic assessments were done before and after pranayama sessions. Maximum phonation duration, pitch, loudness, subglottal pressure, glottal airflow, laryngeal resistance and conductance along with acoustical parameters such as average F0, jitter, and shimmer, soft phonation index, noise to harmonic ratio, cepstral peak prominence, and smoothened cepstral peak prominence were analysed. Results The results revealed significant improvement in the maximum phonation duration, glottal airflow and pressure, average fundamental frequency, and cepstral peak prominence after practice suggesting that it has an effect on voice parameters. Conclusion Bhramari pranayama is effective in improving the acoustic and aerodynamic parameters of voice. The same needs to be investigated in hyper- and hypofunctional voice disorders in the future studies.

“…There may be changes in the postoperative voice performance due to trauma occurring during orotracheal intubation or edema occurring thereafter in the larynx. A study based on a large series of patients conducted by Sorensen et al reported a significant increase in jitter% and shimmer% values in the acoustic voice analysis performed 12-24 hours after surgery [6]. In another study evaluating the postoperative acoustic voice analysis of patients who underwent thyroidectomy and parathyroidectomy, patients with nerve damage and/or injury were excluded, and a significant deterioration in the F0 and shimmer% values was detected in the first 24 hours postoperatively [11].…”

ObjectiveChanges in voice performance in the postoperative period due to trauma suffered during endotracheal intubation or edema occurring in the postoperative period are often observed. The present study aimed to evaluate the effects of different types of intubation tube applications on voice performance in the early postoperative period using objective and subjective voice analysis methods.Materials and MethodsA total of 88 patients who underwent endotracheal intubation either using a cuffed endotracheal (n = 44) or spiral-embedded cuffed endotracheal (n = 44) tube were included in this study. An endotracheal tube of 7.5 mm was used for female patients and that of 8 mm was used for male patients. Preoperative acoustic voice analysis was performed, and fundamental frequency (F0), jitter%, and shimmer% values were recorded. In addition, the voice handicap index-30 (VHI-30) questionnaire was completed by the patients for subjective evaluation. The same procedure was repeated in the first 48 hours postoperatively. The preoperative and postoperative data were statistically compared. In addition, the effect of the type of endotracheal intubation tube on acoustic voice analysis parameters and VHI-30 scores was statistically evaluated.ResultsIn the early postoperative period, a significant decrease in the F0 value and a significant increase in jitter% and shimmer% values were detected. The VHI-30 score was also found to be significantly higher in the early postoperative period than in the preoperative period. The effects of both the intubation tubes on voice performance were found to be similar.ConclusionObjective and subjective evaluations revealed that voice performance was declined in the early postoperative period after orotracheal intubation.
