Abstract

Die Erfindung betrifft ein Verfahren, mit dem Sprache in gestörter Umgebung mit möglichst hoher Sprachqualität erfaßt wird. Dazu wird ein kompaktes Array aus beispielsweise zwei Einzelmikrofonen durch Signalverarbeitungsverfahren aus adaptivem Strahlformen und spektraler Subtraktion zu einem System zusammengefaßt. Das Referenzsignal des Strahlformers wird durch Kombination mit einer spektralen Subtraktion von Sprachsignalanteilen soweit befreit, daß ein Referenzsignal der Störung entsteht und der Strahlformer hohe Gewinne ergibt.
