A method for detecting cough sounds from a sound wave of a subject includes applying features extracted from the sound wave to at least two electronic pattern classifiers including a first classifiertrained to detect an explosive phase of a cough and a second classifier trained to detect one or more post-explosive phases of the cough sound. The features extracted from the sound wave are applied to the second classifier after the first classifier has classified features of the sound wave as an explosive phase of a cough sound. 一种用于从受试者的声波中检测咳嗽声音的方法包括：将从声波中提取的特征应用于至少两个电子模式分类器，所述至少两个电子模式分类器包括训练为检测咳嗽的爆发相位的第一分类器和训练为检测一个或多个咳嗽的后爆发相位的第二分类器。在第一分类器将声波的特征分类为咳嗽声音的爆发相位之后，从声波中提取的特征以应用于第二分类器。
