    摘要: A system comprising at least one hardware processor and a non-transitory computer-readable storage medium having stored thereon program instructions, the program instructions executable by the at least one hardware processor to: receive a voice recording comprising a phonation by a subject, analyze said voice recording to calculate a fundamental frequency contour curve of said phonation, measure at least one of (i) a time period from a start of said phonation until said contour curve reaches a settled level, (ii) a slope of said contour curve during said time period, and (iii) an area under said contour curve during said time period, and determine a glottal closure insufficiency in said subject based, at least in part, on said measuring.
