We propose a new glottis signal model. Most glottal pulse shape models have been
obtained so far by concatenating a small number of curved segments. We propose here an
alternative approach which consists of expanding the signal into a combination of a finite set
of basic time functions. These functions are chosen taking into account the point-like and
non-linear character of the acoustic voice source. We establish a mathematical relationship
between the weights of the individual time functions and the Fourier coefficients of the signal …
