Abstract

Die Erfindung betrifft ein Verfahren zur Codierung von Sprachsignalen, insbesondere von sogenannten 'Sprach-Onset'-Abschnitten. Durch Festsetzen des ersten Verstärkungsfaktors wird die Datenmenge zur Darstellung der Gesamtheit von erstem oder adaptivem Verstärkungsfaktor und adaptivem Codebucheintrag reduziert, wodurch andere Parameter, welche im Zuge der Sprachcodierung auftreten, genauer dargestellt werden können.Die Erfindung betrifft weiterhin ein Verfahren zur Übertragung von derart codierten Sprachsignalen.
