The aim of this study is to comparatively review and evaluate three variants of the glottal
inverse filtering algorithm based on iterative adaptive inverse filtering (IAIF): the Standard
algorithm, and two recently proposed variants that use iterative optimal preemphasis (IOP)
and a glottal flow model (GFM), respectively. To enable an objective evaluation, a
computational physical model of voice production is used to generate time-domain signals
pertaining to both the input glottal flow and the output speech pressure, for a wide range of …
