| Методика субъективных испытаний для оценки систем речевой связи, включающих алгоритм подавления шумов |
В данной Рекомендации описывается методология для оценки субъективного качества речи в условиях шума и пригодная, в частности, для оценки алгоритмов подавления шума. Эта методология использует отдельные шкалы оценки, чтобы независимо оценивать субъективное качество только речевого сигнала, только фонового шума и общее качество. |
