Abstract

В одном способе осуществления данное изобретение включает способ улучшения восприятия языка в многоканальном звуковом сигнале. Этот способ включает сравнение первой характеристики и второй характеристики многоканального звукового сигнала для генерации коэффициента ослабления. Эта первая характеристика отвечает первому каналу этого многоканального звукового сигнала, содержащего языковые и неязыковые звуковые сигналы, а вторая характеристика отвечает второму каналу этого многоканального звукового сигнала, который преимущественно содержит неязыковые звуковые сигналы. Этот способ дополнительно включает корректирование этого ослабляющего коэффициента, согласно оценке вероятности языка, для генерации скорректированного коэффициента ослабления.
