Abstract
AIM
To analyze the accuracy of traditional acoustic measurements (F0, perturbation, and noise) and formant measurements in discriminating between women with and without voice disorders, and with different laryngeal disorders.
STUDY DESIGN
A descriptive, cross-sectional, and retrospective.
METHOD
Two hundred and sixty women participated. All participants recorded the spoken vowel /Ɛ/ and underwent laryngeal visual examination. Acoustic measures of the mean and standard deviation of the fundamental frequency (F0), jitter, shimmer, glottal-to-noise excitation ratio, and the values of the first three formants (F1, F2, and F3) were obtained.
RESULTS
Individual acoustic measurements did not demonstrate adequate (<70%) performance when discriminating between women with and without voice disorders. The combination of the standard deviation of the F0, shimmer, glottal-to-noise excitation ratio, F1, F2, and F3 showed acceptable (>70%) performance in classifying women with and without voice disorders. Individual measures of jitter as well as F1 and F3 demonstrated acceptable (>70%) performance when distinguishing women with different laryngeal diagnoses, including without voice disorders (healthy larynges), Reinke's edema, unilateral vocal fold paralysis, and sulcus vocalis. The combination of acoustic measurements showed excellent (>80%) performance when discriminating women without voice disorder from those with Reinke's edema (mean of F0, F1, and F3) and with sulcus vocalis (mean of F0, F1, and F2).
CONCLUSIONS
Individual formant and traditional acoustic measurements do not demonstrate adequate performance when discriminating between women with and without voice disorders. However, the combination of traditional and formant measurements improves the discrimination between the presence and absence of voice disorders and differentiates several laryngeal diagnoses.
