Abstract
Systems and methods of predicting glottal insufficiency by at least one hardware processor including receiving a voice recording comprising a phonation by a subject, analysis of the voice recording to calculate a fundamental frequency contour curve of the phonation, and measurement of at least one of (i) a time period from a start of the phonation until the contour curve reaches a settled level, (ii) a slope of the contour curve during the time period, and (iii) an area under the contour curve during that time period. In certain embodiments, the processor subsequently, determines a glottal closure insufficiency in the subject based on these measurements.
