Abstract :
Presents two findings regarding an algorithm proposed by Milenkovic (1986) for determining the source and transfer function of the human vocal system. First, the authors show that more reliable estimates of the glottal endpoints can be obtained by modifying the procedure used to update the initial endpoint estimates. Second, they show that the algorithm is useful only for analyzing sounds of low to moderate pitch, because of its dependence on an initial transfer function estimate obtained by linear prediction
