Abstract

Винахід належить до обробки звукових сигналів, поліпшення сприйманості мови в багатоканальному звуковому сигналі. Спосіб включає порівняння першої характеристики і другої характеристики багатоканального звукового сигналу для генерації коефіцієнта ослаблення, при цьому перша характеристика відповідає першому каналу багатоканального звукового сигналу, який містить мовні і немовні звукові сигнали, а друга характеристика відповідає другому каналу багатоканального звукового сигналу, який, переважно, містить немовні звукові сигнали. Спосіб додатково включає в себе коректування послаблюючого коефіцієнта, згідно з оцінкою імовірності мови, для генерації скоректованого послаблюючого коефіцієнта та включає в себе ослаблення другого каналу з використанням скоректованого послаблюючого коефіцієнта.
