ABSTRACT
Introduction:
The understanding of normal vocal production is essential to guide any voice professional as it is fundamental to understand the effects of the posterior glottal gap on the vocal quality.Objective:
The aim of the present study was to verify the association between glottic closure, acoustic parameters, and some characteristics of the videolaryngostroboscopy of young women without vocal complaints nor laryngeal disorders.Methods:
This is a cross-sectional study with 56 women between 20 and 30 years old who underwent videolaryngostroboscopy. The acoustic parameters of the vowel /a/ were analyzed using the Praat software, Release 4.6.10 (Paul Boersman and David Weenik, Amsterdam, Netherlands). StatisticalAnalysis:
The chi-squared, Fischer, and Kruskall-Wallis tests were applied, with 5% significance.Results:
Significant occurrence of posterior glottal gap (85.71%, p < 0.001), of normal vocal folds vibration amplitude (82.14%, p < 0.001), and of absence of significant constriction of the laryngeal vestibule (98.21%, p < 0.001); no significant association of the glottic closure with the vocal acoustic parameters; no significant association of glottic closure, vocal folds vibration amplitude, and constriction of the laryngeal vestibule.Conclusion:
There was a predominance of posterior glottal gap, normal vocal folds vibration amplitude, and absence of laryngeal vestibule constriction, and no relation with the acoustic parameters, suggesting that the posterior glottal gap did not generate impact on the vocal production of the young adult women studied (AU)Palabras clave
