A stroboscopic evaluation was prepared for every participant. Additionally, the voice classification and features of individuals were correlated statistically. <strong>Results:</strong> Statistically significant difference were observed between the voice categories and the size of stomatopharynx, the shape of the hard palate, the length of the vocal folds, the width and thickness of the vocal folds, as well as the tone of speech, in male singers. Statistically significant differences were also observed between the voice categories and all the variables except the shape of epiglottis, the color of speech and the shape of the vocal folds, in female singers. <strong>Conclusions:</strong> There is correlation between the morphometric characteristics of the vocal folds and the voice categories.展开更多

All participants underwent stroboscopic and cervical posterior-anterior radiographic imaging of their oral pharyngeal and laryngeal area. Additionally, the voice classification and features (e.g., height, weight) of individuals were correlated statistically. <strong>Results:</strong> Statistically significant correlations were observed between the VC of the participants with the Phonetic Area (PA) (r = −0.451, p = 0.001) and the VC with the Oral-pharyngeal Cavity (OPC) area (r = −0.402, p = 0.001) in the total sample. Specifically, in male singers, the PA and VC correlation was r = −0.319, p = 0.047, and the VC and OPC area was r = −0.328, p = 0.044. Likewise, in female singers, the PA area and VC and PA were r = −0.336, p = 0.041 and the OPC area and VC were r = −0.344, p = 0.039. The analysis confirmed no correlations between VC and height and body weight. <strong>Conclusions:</strong> The cervical posteroanterior radiography in conjunction with laryngeal stroboscopy provided new morphometric correlations of the VC of professional singers with their Oropharyngeal and Laryngeal Anatomy.展开更多
