Abstract

Die Erfindung betrifft ein Verfahren zur Geschwindigkeitsmodifikation von Sprachsignalen, insbesondere digitalisierten Sprachsignalen. Bei diesem Verfahren wird ein analoges Sprachsignal digitalisiert und in einem Speicher gespeichert. Außerdem wird ein Faktor α definiert, um den das Sprachsignal verlängert oder verkürzt wird. Über das Sprachsignal wird eine Fensterfunktion mit einem ersten steigenden Abschnitt, einem zweiten, sich direkt an den ersten Abschnitt anschließenden, konstanten Abschnitt und einem dritten, sich direkt an den zweiten Abschnitt anschließenden, fallenden Abschnitt, gelegt.
