Resumen
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

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. [--]
