Abstract

In this paper, we discuss the estimation of a glottal excitation source using the glottal inverse filtering (GIF) analysis method. The WRLS-VFF-VT algorithm, which sequentially estimates the filter coefficients, estimation error, the variable forgetting factor, the pitch period, and the instant at which the glottis closes, can be applied to GIF analysis. For the estimation of the pitch period and the glottal opening/closed instants, we can use the VFF signal. The performance of this method is compared with other methods such as the two-pass and two-channel methods
