Abstract

Die Erfindung bezieht sich auf eine Schaltungsanordnung für eine Verbesserung der Verständlichkeit von ggf. Sprache (px) enthaltenden Audiosignalen (i) mit einem Eingang (I) zum Eingeben eines solchen Audiosignals (i). Vorteilhaft wird die Schaltungsanordnung durch einen Sprachdetektor (SD) zum Detektieren von Sprache (px) in dem eingegebenen Audiosignal (i) und zum Bereitstellen eines Steuersignals (s) zum Steuern einer Sprachverarbeitungseinrichtung (SV) und/oder eines Sprachverarbeitungsverfahrens zum Verarbeiten des Audiosignals (i). Vorteilhaft ist entsprechend ein Verfahren zur Verarbeitung von ggf. Sprache enthaltenden Audiosignalen (i), bei dem in einem Audiosignal (i) enthaltene Sprache bzw. Sprachanteile (px) detektiert werden und abhängig von dem Ergebnis der Detektion ein Steuersignal (s) für eine Sprachverarbeitungseinrichtung (SV) und/oder ein Sprachverarbeitungsverfahren für eine Sprachverbesserung erzeugt und bereitgestellt wird.
