1. A method for detecting cough sounds from a sound wave including the steps of:
acquiring the sound wave in electronic format;
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 sound and a second classifier trained to detect one or more post-explosive phases of the cough sound, the second classifier being arranged according to a training that is negative in respect of the explosive phase and positive in respect of portions of the cough sound subsequent to the explosive phase; and
identifying the cough sounds based on outputs from the first classifier and the second classifier.
