Method and apparatus for maintaining multi-channel audio speech audibility with minimal impact on immersive experience

摘要

METHOD AND APPARATUS FOR MAINTAINING SPEAKER AUDIBILITY IN MULTIPLE CHANNEL AUDIO WITH MINIMUM IMPACT IN INVOLVING EXPERIENCE. The present invention relates to a method of enhancing speech audibility 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 probability value to generate an adjusted attenuation factor. The method further includes attenuating the second channel using the adjusted attenuation factor.
