Experiences with the IIR cepstral model based on Padé approximation of the exponential function indicate some problems with stability. An experiment in designing a FIR cepstral vocal tract model has been made. The computation of the impulse response of the FIR filter that realizes the vocal tract model can be accomplished either using the window method of digital filter design or by a recursive computation directly from real cepstrum using the minimum-phase approximation.
