Method, apparatus and computer program for enhancing speech audibility in a multi-channel audio signal

摘要

"METHOD, APPARATUS AND COMPUTER PROGRAM FOR IMPROVING SPEAKING AUDIOBILITY ON A MULTI-CHANNEL AUDIO SIGN". The present invention relates to a method of enhancing speech audioability in a multi-channel audio signal. The method includes comparing a first feature and a second feature of the multi channel audio signal to generate an attenuation factor. The first feature corresponds to a first channel of the multi-channel audio signal containing speech and non-speech audio, and the second feature corresponds to a second channel of the multi-channel audio signal containing predominantly non-speech audio. The method further includes adjusting the attenuation factor according to a speech likelihood value to generate an adjusted attenuation factor. The method further includes attenuating the second channel using the adjusted attenuation factor.
