Cepstral speech modelling, continued fractions and excitation matching in speech synthesis.
Result description
In the contribution the principle of cepstral speech modeling based on continued fraction expansion of exponential functions, the Padé approximation, is shortly described. Further an improvement of the cepstral speech synthesis is presented. The RMS value of the exact residual signal corresponding to the cepstral vocal tract model is estimated in the frequency domain using the Parseval's theorem and is applied to excitation and gain matching of the cepstral speech production model.

Original language description
In dem Beitrag wird das Prinzip der cepstralen Sprachmodellierung dargestellt. Das cepstrale Vokaltraktmodell wird mit Hilfe der Entwicklung der Exponentialfunktion in einen Kettenbruch, der Padé-Näherung, konstruiert. Die Intensität der Anregung des cepstralen Vokaltraktmodells wird in der Frequenzebene mit Hilfe der Paserval'schen Gleichung aus der Energie des Restssignasls bestimmt.
