Abstract
In this paper a new inverse filtering technique for the time-domain estimation of the glottal excitation is presented. This approach uses the DAP modeling for the vocal tract characterization, and a spectral model for the derivative of the glottal flow. This spectral model is based on the spectrum of the KLGLOTT88 model for the glottal source. The proposed procedure removes the glottal source from the spectrum of the speech signal in an accurate manner, particularly for highpitched signals and singing voice, and the estimated glottal waveforms present less amount of formant ripple.
