Methods and apparatus for cough detection in background noise environments

摘要

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 classifier trained 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.
