Description in English
The paper describes the realization algorithm of the cepstral IIR vocal tract model with poles and zeros, which is optimized from the viewpoint of the implementation on a fixed-point digital signal processor with dual Harvard architecture. Cepstral coefficients are used in the IIR model as coefficients of a FIR digital filter, which is introduced in the IIR digital filter instead of the delay blocks. The orders of the FIR and IIR filters depend on approximation accuracy and on sampling frequency.
