title: [Quantitative spectral evaluation of vocal hypofunction].
abstract: The purpose of this study was to explore the interaction between voice asthenicity and the acoustic prediction of vocal hypofunction. One hundred and seven phonatory samples of Reinke's edema were categorized by listeners using GRBAS scale. Seven frequency and time domain parameters were used to predict perceptual severity of asthenicity. Logistic regresion analysis showed that a useful measure for the prediction of asthenicity was the loss of harmonic components in the middle and upper portion of the spectrum. A spectral classification of vocal hypofunction is proposed.
