Abstract
A linear-predictive-coding (LPC) based method for computing glottal pulses is presented. The method is based on modeling the speech production mechanism with three digital filters. The glottal contribution to the speech spectrum is first estimated with two consecutive LPC analyses. After the effect of the glottals are eliminated the vocal tract and radiation effects are modeled. Glottal waves close to the natural shape can be achieved with this straightforward method. Applications to speech coding are briefly described
