Abstract

Die Erfindung betrifft ein Verfahren zum Bestimmen des zeitlichen Verlaufs einer Grundfrequenz einer zu synthetisierenden Sprachausgabe. Die Erfindung zeichnet sich dadurch aus, daß Vorgabemakrosegmente der Grundfrequenz mittels eines neuronalen Netzwerkes bestimmt werden, und diese Vorgabemakrosegmente mittels in einer Datenbasis gespeicherten Grundfrequenzsequenzen nachgebildet werden. Durch das erfindungsgemäße Verfahren wird die Grundfrequenz auf Grundlage eines größeren Textabschnittes, der mittels des neuronalen Netzwerkes analysiert wird, erzeugt, wobei aus der Datenbasis Mikrostrukturen in der Grundfrequenz aufgenommen werden. Die derart gebildete Grundfrequenz ist somit bezüglich ihrer Makro- als auch ihrer Mikrostruktur optimiert. Hierdurch wird ein äußerst natürlicher Klang erzielt.
